Beaver Tail and Bluff
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.
