  • A distant lightning storm moves south past the Badlands in South Dakota. The red sky in the west was casting a soft glow on the tops of the cliffs. This was a typical late summer evening when a thunderstorm formed over the Black Hills and moved out across the plains.<br />

  • At nearly 11,000 feet in elevation, the Beartooth Highway is the highest road in the Northern Rockies. The scenic 68 mile byway starts near Red Lodge, Montana, and leads to the northeast entrance of Yellowstone National Park. Summers are very short in this harsh alpine zone. It was stormy when I drove up a couple weeks ago. Once I reached Beartooth Pass, a mix of rain, snow, and graupel was falling from the sky. But I knew a rainbow was likely as soon as the sun came back out. So I put on a rain jacket and climbed up this pile of rocks to get a better view. When the rainbow first appeared, it was so close and vivid it felt like I could reach out and touch it. But it only lasted a few minutes as the storm moved away and the sun quickly melted the snow and graupel that coated the ground.

  • Cave-in-Rock is a cavern carved out of a limestone bluff along the Ohio River. The 500 foot long cave has a skylight at the end so it's not completely dark, and a side room where bats were sleeping on the ceiling. Discovered in 1739 by a French explorer, this place has a colorful history. It was first used as a hideout for pirates and outlaws. They would rob riverboats carrying their goods down the river to sell. In the centuries since, this unique cave has been used as a tavern, a church, a shelter, and is now preserved as a state park. It was a challenge to stay out of the rain on this day, but I liked the way the stormy clouds matched the darkness of the cave.<br />

  • Mammatus clouds are a cellular pattern of pouches that hang beneath a much larger cloud. The formation isn't very distinct here as the wind breaks it up. This stormy scene occurred over the Bighorn Mountains in northeast Wyoming.<br />

  • I had to pull off of I-90 to shoot this distant view of a thunderstorm rolling out of the Bighorn Mountains. But I nearly got stuck on a muddy road.
    Where the Rain Falls
  • On this evening I headed up into the hills to watch lightning. The first storm that made me head out the door wasn't any good for pictures, since most of the lightning was intra-cloud. But then I watched another cell pop up to my south. As this updraft exploded into the starry sky, it started producing positive lightning strikes. Positive lightning accounts for 5-10% of all lightning, and is up to 10X more powerful than negative strikes with a peak discharge of 1 billion volts. It originates from the top of a thundercloud and travels through miles of air before striking the ground. Positive bolts can hit up to 25 miles away from the parent thunderstorm. These "bolts from the blue" are especially dangerous because people may assume they're a safe distance away from the storm when they strike.<br />
The night couldn't have been more perfect for watching lightning.A full moon helped to light up the landscape and gave the thundercloud a silver lining. I stayed in the same spot for hours as multiple storms followed the same path.

  • A series of lightning bolts strike in the distance beyond Spring Lake. This storm was part of a derecho that formed over Nebraska and caused extensive damage as it headed towards Illinois. Even though this part of the storm was weaker it still displayed a nice shelf cloud and put on a great lightning show.<br />

  • On the longest day of the year, a thunderstorm came rolling through Antioch, Illinois. Lightning is a lot more challenging to capture during the day. At night you can use a long exposure of 30 seconds and try to catch a bolt of lightning in that time frame. But during the day, you have to use shorter exposure times. This storm was dark enough that I could use a 2 second exposure and eventually caught these twin strikes.<br />

  • A few minutes earlier this supercell produced a tornado, but I couldn't see it from my vantage point. I thought it was going to do it again here, but there was only this funnel cloud.

  • I couldn’t let NEOWISE leave without trying to capture it over Devils Tower. But this wasn’t the shot I had in mind. The forecast called for mostly clear skies after earlier severe weather exited. But sometimes what actually happens is so much better than what I can imagine. This supercell popped up to the west around 10PM and the anvil quickly blocked out the comet. But then just as the storm was showing its best mothership structure during a close encounter with the tower, a hole in the clouds opened up. It was perfectly placed to reveal the comet once again for just a few minutes. It’s a good thing that most of the lightning was intracloud. If bolts of lightning were jumping out they would have been too bright to expose for the comet. Every single flash highlighted or backlit a different part of the storm. While the lightning continued for most of the night, I was glad the large hail stayed away. I didn’t want to test the hailproofness of my tent.
    A Hole in the Clouds
  • When the lightning rod at the top of Black Mountain started buzzing, I knew I had to descend to escape the lightning danger. But I'm glad I returned afterwards, because the  sunset was incredible. Mammatus filled the sky as the storm cleared and it took on an orange color as the sun lowered. All the smoke in the air added to the surreal atmosphere. The fire lookout structure was recently closed to the public because it's fallen into disrepair.
    Lookout Above
  • When I saw this strongly rotating thunderstorm heading my way, I found a hilltop near Ranchester to watch it come in. This is the first time I've seen a funnel cloud this close to home.

  • On this late June day in central Montana, I didn’t think I would end up with any storm pictures. Just as the storms started firing at 5PM my car suffered a flat tire. After all the miles I’ve driven while stormchasing, it was bound to happen eventually. But thankfully this cell took it’s time and let me get my spare on before I could catch back up. Near the aptly named town of Grass Range, the sun came out as the rain and hail moved to the north. The golden light contrasted with the cool blues on the other side of the sky. Outflow winds gave meaning to the term (not yet amber) "waves of grain". I tried to use a long enough exposure to show some of this movement in the wheat. From here it would be a long 250 mile drive home on a donut tire.

  • This tornado near Broadwater, Nebraska, developed almost on top of me while I was attempting to core punch the storm. At the intersection of Rd 78 and Hwy 385 I was close enough to hear the roaring waterfall sound and feel the intense RFD winds. But I couldn't see it because the storm had become HP (high precipitation) and visibility was horrible. As I fled south on Hwy 385 debris started flying past me including sheet metal hitting my car. A semi truck that I passed would be flipped over on it's side and all the sign posts at the nearest intersection snapped in half. Once I made it a safe distance away (about 5 miles) I stopped and took this picture looking north. Visibility was still bad, I couldn't see the tornado and I even missed it the first time after reviewing my pictures. But after enhancing the contrast the twister became visible in the rain shaft on the left.

  • A severe thunderstorm rolls across the hills of northeast Wyoming. This storm formed from orographic lifting over the Big Horn Mountains, before moving southeast. The curl at the base of the rain shaft is an indication that a wet microburst is occurring. Caused by evaporational cooling weakening a thunderstorm's updraft, it results in a sudden release of torrential rain and strong damaging winds in a localized area. But no damage was reported with this storm because it was in such a remote area. There are no paved roads (other than I-90), towns, or services for at least 25 miles in any direction.

  • A shelf cloud approaches a grassy field near Mackinaw, Illinois. This storm hit a half an hour before sunset. It actually became so dark that fireflies started to come out.<br />

  • With winds blowing over 40 mph, it was not the most pleasant evening for a hike. At first it was sunny, but the weather changed quickly as a cold front blew through. A fiery orange glow appeared at sunset while rain showers moved in over the mountains. I was standing on top of Lodge Trail Ridge, a mile high vantage point overlooking the small town of Story to the west. There's a lot of history here, as this ridge sits in between Fort Kearney and the Fetterman Battlefield. The fort was established to protect travelers of the Bozeman Trail, an offshoot of the Oregon Trail which passed through Indian land. Tensions culminated in 1866 in an ambush led by Crazy Horse that killed 81 soldiers. It was the US Army's worst defeat in the West until the Battle of Little Bighorn 10 years later.

  • I arrived in Badlands National Park just in time to watch the first of 4 thunderstorms move through.
    Welcome to the Badlands
  • Tumbleweeds rolled across the road as I drove through the Nebraska panhandle with this stunning supercell behind me. I was looking for something, a barn, winding road, etc, to shoot in front of the storm. But mostly I wanted to capture a time lapse without power lines getting in the way. Finally I found what I was looking for: a lone tree on the edge of a barren field. I ran out to the tree and had 6 minutes to take pictures before the winds would blow over my tripod.
    Tree Vs Supercell
  • With severe weather in the forecast, I headed downstate to do some storm chasing. This cell formed over the Laramie Mountains before pushing east onto the High Plains. At first it took it's time maturing. But just before 4PM it transformed from an ok looking storm into this in only 10 minutes. As the storm moved into a better wind shear environment, it turned into a mothership supercell displaying very impressive structure. I was mesmerized watching it roll across the Nebraska stateline outside of La Grange. Despite the ominous and otherworldly look, the storm wasn't severe at this time. As it passed over me it brought small hail and blowing dust with lots of tumbleweeds.
    Mothership Supercell
  • I was driving through southeast Montana when I started seeing flashes to the west.I pulled in to Rosebud Battlefield State Park to try to get some lightning shots. Most of the lightning was intracloud but occasionally a bright bolt of lightning would jump out and strike the ground, making it a challenge to get the exposure right. This is a very remote part of the state, about 35 miles from the nearest town. It was at this location in 1876 that one of the largest battles of the Indian Wars took place. The Battle of Rosebud also played a role in the defeat of Colonel Custer one week later at Little Bighorn.

  • An updraft is a rising current of air that often leads to thunderstorms. The updraft of a developed storm is also the most active part with large raindrops and hailstones constantly rising and falling. As the rain and hail collide, this creates an electric field and eventually lightning. As the sun set, it gave this storm a beautiful orange color and highlighted the details and the structure.<br />

  • This was the best lightning storm I saw all year. A couple thunderstorms passed very close, but the rain stayed out of the way. Sometimes I stack lightning shots, but this is just one exposure. The two lightning crawlers occurred about 15 seconds apart within the 30 second exposure. After chasing some storms to the south and coming back home I think I saw about 10 thunderstorms on this day. There are often deer in this field at night, you can see a couple under the bright streetlight.<br />

  • Even though 2019 was a very active storm season overall, it started quite late. It was well into June before there were any thunderstorms worth chasing locally. I caught up with this long shelf cloud on the plains outside of Broadus, Montana. When air cooled by rain hits the ground, it spreads out ahead of the storm. This lifts the warmer, moist air ahead of it, which condenses into a shelf cloud. They are usually associated with strong winds and heavy rain, but rarely tornadoes because they do not have the right shape.

  • A vivid rainbow appeared on the other side of this storm near Crazy Woman Canyon.

  • In front of me was a rainbow, lightning to the left, a colorful sunset behind me, and to my right were baby bighorn sheep prancing around. When the downpour ended and the sun came out, it was an overwhelming few minutes and I didn’t know where to point my camera. I was just lucky to be at this overlook in Badlands National Park. When the storm was closing in I made a bad decision to turn down a very muddy road. But somehow my car made it back out after spinning the wheels for 5 minutes. My last 2 visits to this South Dakota national park were both very short and involved waiting out heavy thunderstorms, which isn't all that enjoyable in a tent. One of these days I'll return when the weather is actually nice. But bad weather makes for the best pictures.

  • It wasn't until 7:30PM that I decided to intercept this supercell to my south. The rotation here was very apparent. It was nice seeing some of the best storm structure of the year so close to home.
    Ucross Supercell
  • A supercell lurked in the darkness. Every few seconds a flash would illuminate the thundercloud and show a silhouette of the sharp spires of the Badlands. This was the 4th storm I watched this evening. Rumbles of thunder slowly grew louder as yet another storm approached from the west and threatened to block the view of this one. Badlands National Park is one of my favorite places to capture storms. Even when they’re 100 miles away, the views here are excellent. And distant storms are preferred when I’m camping. The Badlands are very exposed to the elements. There is no escaping the rain, wind, and mud. An earlier downpour soaked me to the skin but the wind that followed dried me in minutes. The mud is the type that cakes to the bottom of your shoes making every footstep heavier. But a few hours in the hot sun and the mud is baked dry. At the time of this picture tennis-ball sized hail was reported in the Pine Ridge Reservation to the south. The lights are from the metropolis of Interior, population 94. The lightning was mostly cloud-to-cloud; this was the only strike I captured out of 500 shots.
    Strike Beyond Interior
  • On my way back from South Dakota I had a chance to intercept this severe storm at Devils Tower. I got there in time to watch the shelf cloud roll by over the tower. This storm was a prolific hail producer. I misjudged the movement of the storm and ended up getting caught on the edge of the hail core as I fled east towards Sundance. Golf ball-sized chunks of ice left additional dents in my car. But I got off easy, there were a lot of cars with smashed windshields. Hailstones up to 4.5" in size damaged crops further east where the storm also produced a tornado.

  • While I was visiting Illinois I had the chance to chase this storm outside of the town of Benson. The storm wasn't much, although it had some OK structure. But it was nice being back, since central Illinois is where I first learned how to storm chase.

  • This severe thunderstorm rolled across the grassland near Decker, Montana late at night. There were dozens of wildfires burning across Montana. Before this storm hit, the air was mostly clear. But the strong winds brought in thick smoke from the northwest. It smelled like there was a fire nearby, even though there were none in the immediate area. All the lightning had a reddish-orange tint to it.

  • Before heading back, I wanted to make it to the Upper Lost Twin Lake. This was more difficult than I expected, since there was no trail, and I had to hop across boulders still wet from the morning storms. This was the view from the hill above the lower Lost Twin Lake.

  • The horizontal cloud stretching out from the supercell is known as a beaver tail. It is formed from moist inflow winds feeding into the storm. The winds were very strong as you can see from all the dust picked up underneath. There was a tornado ongoing at this time which damaged 2 homesteads near the Nebraska/Wyoming border. But it wasn't visible from my location and I couldn't get any closer because there weren't any roads heading east.
    Beaver Tail
  • It was a very dark night at Devil's Tower, in between lightning bolts. The lightning was difficult to expose for, since it was infrequent, and usually very bright. This was one of the dimmer bolts. I was standing underneath the back door of my car to stay out of the rain when I took this.

  • A partial rainbow hangs above the buttes and mesas of eastern Arizona. On this early November afternoon, scattered rain showers drifted across the landscape. The shadows and patches of sunlight revealed the full range of colors that the Painted Desert is known for. This desert was once a forest with a much wetter climate, and a wide variety of wildlife. But now it's filled with petrified logs and fossils. Also found in Petrified Forest National Park are many archaeological sites including pueblos, petroglyphs, and other artifacts, some of which are thousands of years old.

  • While camping at Garden of the Gods, I watched a storm roll through at 8am. I would have liked to make a time lapse but the storm was just approaching too slowly. A proper shelf cloud never formed, it was mostly dark scud clouds that drifted across the sky. Once the rain started falling, and the lightning started striking nearby, I quickly made it back to my car where I waited out the storm.<br />

  • This thunderstorm formed ahead of an outflow boundary near Goodfield, Illinois. The updraft at the beginning was strong enough to keep the rain aloft. Then suddenly, a column of sinking air within the thunderstorm rushed to the ground, bringing strong winds and torrential rain. This is known as a microburst. It is a very localized event that can be difficult to predict. For a pilot, a microburst is the most dangerous part of a thunderstorm. Microbursts have caused numerous plane crashes, they are especially dangerous when an aircraft is trying to land.<br />

  • The air felt heavy and still. As it rotated closer, this supercell seemed to grow wings. Within a couple of minutes Sundance Mountain was swallowed up by the precipation core. The 'calm before the storm' does not happen with every storm, but when it does it's very noticeable. Then a giant bolt of lightning struck out of frame, with a deafening thunder shattering the silence. An errant hailstone, big enough to leave a bruise, bounced off of the ground with a thud. It was time to move. This cell turned out to be an ice machine, piling up baseball-sized hail on the road, and making the temperature plummet which created hail fog. Chasing storms in and around the Black Hills has it's challenges. Winding roads through hilly terrain makes viewpoints limited and cell signal sporadic. But when everything comes together just right, the structure and color of the storms around here are incredible.

  • I spent Memorial Day chasing storms across the Colorado High Plains. Colorado may not be the first state people think of when it comes to tornadoes. But it actually sees more than 50 a year on average, mostly in the eastern third of the state. Upslope flow causes storms to fire when moist southeasterly winds encounter the Rockies. The Palmer Divide is a ridge east of the Front Range and it creates what's known as the Denver Convergence Vorticity Zone. The changing winds in the DCVZ generates extra spin which makes storms rotate. But many of the tornadoes are weak and short-lived, at least they were on this day. Of the 3 possible twisters I saw, none of them were very clear. This was taken near Holyoke when swirling dust appeared underneath a funnel.

  • On Memorial Day I spent the afternoon following multiple supercells, funnel clouds, and tornadoes across the high plains of Colorado. After a long day I was ready to head for home. But at 7PM the atmosphere still wasn’t done producing. This last storm spun up near the town of Wray. It displayed some impressive structure as it passed over the hills covered with sage brush and yucca. The NWS surprisingly issued a tornado warning for this cell, but nothing came of it. Most of the day had been fast-paced and hectic, dodging hail while surrounded by crowds of chasers there for the same reason. But now it was quiet and peaceful. This was the perfect storm to end the day with before beginning the long drive back.

  • After a shelf cloud passes overhead and before the rain arrives, it's called being 'in the whale's mouth.' With dark, fast-moving, turbulent clouds filling almost the entire sky, and only a narrow opening letting in light, it really can feel like you've been swallowed up by a whale.

  • Badlands are a type of terrain that experiences rapid erosion, estimated to be an inch per year at Badlands National Park. Much of that erosion happens during thunderstorms like this one. When the downpour first started I was disappointed because I didn’t get any shots of the storm structure beforehand. But then there was a break in the rain. It lasted just long enough for me to rush back to this overlook and capture the dark menacing clouds above surrounded by two blueish-green rain cores. Hidden in the ravine below were big horn sheep climbing the steep muddy terrain. The second wall of water hit even heavier than the first and dropped visibility to almost zero. A local told me they had never seen a spring with more rain. And they were right, 2019 was to become the wettest year on record in western South Dakota.

  • After waiting out a heavy thunderstorm at the Pinnacles Overlook, the sun began to come out. Beautiful golden light illuminated everything, a double rainbow appeared with lightning, and bighorn sheep wandered around. It was an overwhelming few minutes as I didn't know where to point my camera.

  • I spent the fourth of July chasing tornadoes in Chugwater, Wyoming. Chugwater has a certain legendary status among storm chasers. Storms form over the Laramie Mountains to the west, and the local terrain seems to enhance tornadic potential. On at least 3 other occasions I've seen funnel clouds here. And having one of the few paved, east-west highways also makes it a great place to target. Luckily there is not much around for a tornado to damage. I had to pick a spot either below the bluff or on top. I chose on top, which put me a little over a mile away from the developing tornado. Powerful cloud to ground lightning bolts were dropping during tornadogenesis. My camera was left outside to shoot automatically while I stayed in my car.

  • Earlier in the spring I came across this overlook on a hilltop with a view of the mountains to the west. I knew it would be be the perfect spot to watch a storm roll out of the Bighorns, I just needed to wait for the right storm. My first attempt didn’t yield the pictures I wanted as the cell went too far south. But the second time’s a charm. This storm intensified after I got here and started spitting out dozens of close lightning bolts. It was dark enough that I could use a longer shutter speed, and capture about 40% of the strikes that occurred. But there were many more out of frame to the right. This is a composite image showing 5 of the best strikes. By the time I left there was a small stream running under my car as well as some minor street flooding in Sheridan.

  • It wasn't just a good night for watching lightning, there were plenty of Delta Aquarid meteors as well. This one was particularly colorful.

  • In this part of Montana there’s a whole lot of nothing. The sprawling ranches have more acreage than many towns. I’ve previously driven hours along this road east of Decker without seeing another human. You're more likely to encounter wildlife such as pronghorn antelope, which I've raced across these plains and found that they really can run 60 mph. On a warm August evening I followed this storm for awhile. The radar showed it was producing hail the size of baseballs. But since the core passed through a roadless area, any severe weather went unseen and unreported. Abandoned houses are not hard to find as they are more common than lived-in houses. By now I know where most of them are so I kept driving until I could shoot the storm above this one. When the evening sun came out it highlighted the puffy cumulonimbus clouds receding into the distance. The white containers next to the tree are bee hive boxes. I've noticed them popping up more and more across Montana as it's one of the top honey-producing states.

  • On this evening I headed up into the hills to watch lightning. The first storm that made me head out the door wasn't any good for pictures, since most of the lightning was intra-cloud. But then I watched another cell pop up to my south. As this updraft exploded into the starry sky, it started producing positive lightning strikes. Positive lightning accounts for 5-10% of all lightning, and is up to 10X more powerful than negative strikes with a peak discharge of 1 billion volts. It originates from the top of a thundercloud and travels through miles of air before striking the ground. Positive bolts can hit up to 25 miles away from the parent thunderstorm. These "bolts from the blue" are especially dangerous because people may assume they're a safe distance away from the storm when they strike.<br />
The night couldn't have been more perfect for watching lightning.A full moon helped to light up the landscape and gave the thundercloud a silver lining. I stayed in the same spot for hours as multiple storms followed the same path.

    Moon Behind the Anvil
  • There was an outbreak of at least 3 tornadoes in southeast Wyoming. September tornadoes are very rare in this state. But 2019 has been a strange storm season, both starting late and ending late. This supercell north of Torrington developed a long inflow tail (aka a beaver tail) feeding moisture into the storm. It’s common to feel cool outflow winds coming out of a storm. But when you feel warm and moist inflow winds blowing into the storm that’s when you know tornado potential is high. These opposing winds help tighten up the rotation near the ground. The southeasterly winds were kicking up so much sand and dust I could feel it in my eyes, ears, and mouth. Because of poor ground visibility I didn’t get a very good view of the twister, but the structure was still impressive. When the sun came out it provided a stark contrast between the dark blue clouds and the bright golden grass.
    Beaver Tail and Bluff
  • It was great to get out for my first storm chase of the year. This supercell was showing it's best structure near Upton.
    At the Logging Camp
  • After the storms passed off to the east, the anvil filled the entire sky with mammatus. A small clearing to the west allowed sunlight to shine through and illuminate the clouds. All the ingredients were there for an incredible sunset, so I went to Glendo Reservoir and waited. The colors did not disappoint.
    Glendo Lake Sunset
  • From a distance this South Dakota supercell looked very impressive with a crisp updraft under a clear blue sky.
    Convection Ahead
  • The radar showed hail up to softball sized falling in this area. But I was glad for these horses sake that it missed them.
    Wet Horse Rainbow
  • This was a day I won't soon forget. The forecast called for very humid air, extreme instability, and strong wind shear in the MT/ND/SD area. Having all these conditions come together at the same time is quite rare and I knew something incredible would happen. I just had to be there. The day involved lots of waiting around in eastern Montana until I set my sights on this supercell in the late evening. The storm structure was otherworldly, looking like a tsunami in the sky. When the first tornado dropped there were hills in the way and road options to get closer were limited. But outside of Buffalo, South Dakota, finally the twister became visible. The tornado lifted and planted again about 4 times. It was looking the best as the sun was setting at 9pm. I was never closer than about 9 miles, but this gave me the advantage of seeing more of the storm's structure. Now I finally have a tornado clip to finish up my time lapse film.
    Buffalo Tornado
  • This was the 2nd twister that I saw outside of Buffalo, South Dakota. It danced around, touching the ground briefly and lifting again a few times. But the wall cloud on the right was beginning to show very rapid motion. It was about to drop a wedge tornado, and I knew I had to get closer to get a better view.
    Cute Little Twister
  • While I was visiting Illinois I had the chance to chase this storm outside of the town of Benson. The storm wasn't much, although it had some OK structure. But it was nice being back, since central Illinois is where I first learned how to storm chase.
    Wet Soybeans
  • Lightning activity picked up while I was driving so I stopped at the end of a driveway and took a few pictures until I caught this bolt.
    Electric Hills
  • After riding out this severe thunderstorm outside of Faith, South Dakota, the conditions came together for a spectacular sunset. I stopped on this two-track road in the middle of a prairie, trying not to get stuck in the mud. Gorgeous colors filled the sky in every direction, with occasional flashes of lightning.
    Tumultuous Sky
  • After driving for over 5 hours I finally reached the edge of this powerful supercell just west of Faith, South Dakota. From a distance I could see wall clouds and funnels, but up close they disappeared. I was having trouble recognizing the storm structure until I noticed this horseshoe-shaped RFD cut. The back of the horseshoe shows where a potential tornado would form. There was a short-lived funnel, visible at the bottom center. At the time there was a mobile dopplar radar parked down the road scanning the skies.
    RFD and Funnel
  • On this day a severe MCS (mesoscale convective system) roared across eastern Montana. Since I was out ahead of the storm near Miles City I had plenty of time to find an interesting place to watch it roll in. The Kinsey Bridge is a 4-span truss bridge that crosses the Yellowstone River. The single-lane bridge was built in 1907 and the poor condition made it unnerving to drive across. According to the National Bridge Inventory database, the Kinsey Bridge has a sufficiency rating of 56 out of 100 when it was last inspected. Just after 7PM the gust front passed overhead bringing with it strong winds, blowing dust, and heavy rain.

  • Storms can either bring epic sunsets or none at all. It's all about the timing, and where you are in relation to the storm when the sun goes down. This severe MCS rolled through Miles City, Montana around 7pm. The rain slowly came to an end and a glow began to emerge in the west. I wasn't expecting much, but I found a place to wait (Spotted Eagle Lake) just in case something special happened. The sun only popped out for a couple minutes. But that was enough to light up the entire sky with intense orange and pink. A double rainbow appeared for 15 minutes, which was long enough to allow me to shoot a time lapse of it fading away. The wind died down for just a moment and the reflection in the lake made an almost perfect circle. Even though the long drive wouldn't get me home until after midnight, I'm glad I didn't leave early and miss out on this.
    Reflected Rainbow
  • This severe thunderstorm developed rapidly east of Sheridan. Usually lightning is very difficult to capture during the day. But it was frequent enough that my camera captured 3 bolts in the time lapse.
    Dusty Strike
  • I stopped at the MT/WY stateline and watched this thunderstorm roll off of the Bighorn Mountains. Since there was no wind, I was able to keep shooting a time lapse without getting raindrops on the lens.
    Downpour
  • The last Sunday of April brought the first thunderstorm of the year. After getting hailed on while hiking, I found a place to shoot the storm near Big Horn. These 3 horses seemed unfazed by the threatening sky and mammatus clouds above them.
    Horses and Mammatus
  • Horses graze above a farm in the foothills of the French Alps.
    Horses of Plancherine
  • A horse grazes near the Abbey of Tamie on a rainy day.

  • It rained most of the morning at my campsite on Lost Twin Lake in the Cloud Peak Wilderness. The cold rain was at times accompanied by thunder and lightning, gusty winds, and graupel (snow pellets). Nearby waterfalls grew louder and the sound of a distant rock slide echoed across the lake. My plan of summiting Darton Peak would have to wait for another day. After the last rain shower, the clouds descended and obscured the highest peaks. I took this picture while enjoying a cup of hot coffee as the rain finally stopped. It's difficult to convey just how massive these cliffs are. The sheer granite walls rise 1-2 thousand feet above the lake. If you can see the white speck at the base of the cliff on the right, that is a tent. The top of this bowl-shaped valley, known as a cirque, was carved out by glaciers long ago.
