Cold Front will Bring Snow, Strong Wind, and Bitter Cold Wind Chill Temperatures Sunday Afternoon through Monday Morning

SYNOPSIS: An Arctic cold front will blast south along and east of the Continental Divide this afternoon and evening. Areas of light snow, strong north to northwest wind and bitter cold wind chill temperatures will follow the front into Monday morning.

IMPACTS: Strong north wind with gusts over 55 mph will will pose a blowover risk to high-profile lightweight vehicles on Interstates 25 and 90 across Johnson County, and across the Big Horn Basin late this afternoon through Monday morning. These winds combined with plunging temperatures will also result in bitter cold wind chill temperatures of zero to 10 below across the lower elevations of central Wyoming Monday morning.

Wind Chill temperatures of 20 to 30 below zero in the central mountains
Wind Chill temperatures of possibly 40 below over Powder River Pass and the higher elevations of the Bighorn Mountains.

Rain and a rain snow mix will fall ahead of the front in northern portions of the Bighorn Basin and in Johnson County late this afternoon, before transitioning to all snow with the passage of the front. This will cause roads to already be wet, so although snow amounts will be light, rapidly falling temperatures this evening could result in a flash freeze on road surfaces and will result in road surfaces becoming icy and extremely slick. Blowing snow will further add to this tonight into Monday morning; travel is expected to be difficult and hazardous.
