Funnel and Mesocyclone
Mid-June brought a tornado outbreak on the high plains with dozens of twisters reported in 4 states. I intercepted this strongly rotating mesocyclone while tornado sirens went off in Fort Laramie (the very first settlement in Wyoming according to the sign). Storm chasing in Wyoming is different than in other places. Because roads are so few and far between, it's unlikely that you'll be able to follow a storm for very long. Instead you have to anticipate the storm's movement so you can get ahead of it while staying aware of all the paved road options and escape routes. Then you just have to hope to get some good shots before losing the storm in a roadless area. On the lower right a funnel can be seen under the tightening wall cloud. Even though I didn't see it touch the ground, the time corresponds with a tornado reported to the southwest. After this I packed up my tripod and left in a hurry as small hail began to fall. This supercell had already dropped massive grapefruit-sized (4.5") hailstones and I prefer to keep my windshield intact.
