Cheyenne, Wyo: March 18, 2021, Just because you forecast the weather doesn’t mean you’re immune to it. Meteorologists at the National Weather Service office in Cheyenne, Wyo., have been trapped in their facility since Saturday, thanks to impassible roads and vehicles buried beneath heavy snow. Much of Wyoming, western Nebraska and the Colorado Front Range experienced a historic blizzard over the weekend, part of the same system that whipped up a serious tornado outbreak in the Texas Panhandle. Cheyenne picked up 30.8 inches, 28 of which came down within a 24-hour window. A whopping 22.7 inches fell Saturday alone, the city’s single-greatest calendar day snow total since the start of bookkeeping in 1935. The storm total snow accumulation fell just 1.1 inches shy of a storm in January 1949.
