Beulah Derecho 2:1 Panorama
Pictured is a highly unusual weather event called a derecho. Derechos are a long-lived wind storm that may travel across multiple states and cause widespread damage. They occur a few times a year in the Midwest or Eastern US. What was unusual about this derecho is that it began in Utah at 9AM. Normally the Rockies disrupt organized storm systems, but this one had no problem plowing 750 miles all the way to North Dakota. Hundreds of wind reports ranged from 60 to 110 mph. I intercepted the squall line near the Wyoming/South Dakota border. The severe thunderstorm warning mentioned a storm motion of 100 mph which was a bit difficult to comprehend. I tried to make it to a mountaintop, but then had to go with plan B, which turned into plan C which was pretty much the side of a road off of I-90. The shelf cloud was very ominous. The air was notably calm and quiet just before it struck. One mountain after another vanished into the rain and dust. Then seconds later the wind was roaring and I couldn't even stand up straight.
