Wyoming is part of Great Plains
Every Great Plains region shares one system — the same maps, the same live radar, the same climate record. Wyoming is the windiest state in the country and the emptiest but one, and the two facts make the same forecast. I-80 over Elk Mountain and Arlington closes on ground blizzards under a blue sky, with gates at Laramie and Rawlins and blow-over warnings for anything with a trailer. The mountains keep the snow — Togwotee, the Snowies, the Bighorns — while the Bighorn Basin below them at Worland is high desert that takes ten inches of precipitation a year.
