CHEYENNE – Winter isn’t through with Cheyenne and southeast Wyoming just yet.

Meteorologists at the National Weather Service Office in Cheyenne expect a storm to continue bringing snow into southeast Wyoming, including Cheyenne, through Wednesday, with periods of moderate to heavy, wet snow developing at times.

Forecasters expect the heaviest snow accumulations to occur across the Laramie, Snowy and Sierra Madre ranges, with a total of 6-10 inches possible for the valleys and plains.

A winter storm warning is in effect for the mountains of southeast Wyoming through midday Wednesday.

Winter weather advisories are in effect through midday Wednesday for much of the rest of southeast Wyoming, including the I-80 corridor from Kimball to Rawlins and I-25 corridor from Cheyenne to Douglas.

Snow will continue to fall this morning, then there looks to be a lull this evening before a second round of snow later tonight into Wednesday morning.

“We have two systems – one to the north and northeast of us, and another one to the south and southwest,” NWS meteorologist Bill Mokry said. “This first event that we’re seeing is a frontal boundary and moisture coming from the system in Montana and North Dakota. Then, we’ll have a second system – a low from California moving up into the region, and that will provide a lift in moisture for us for the second round.”

With the break in snowfall, afternoon temperatures will rise above freezing across the region, resulting in snowmelt ahead of the next round of snow tonight.

An additional 1-3 inches is possible with the second round of snowfall tonight and into Wednesday.

Expect high temperatures to warm into the low 40s in Cheyenne today and Wednesday. Thursday’s high temperature will warm into the mid-50s in Cheyenne under sunny skies.

Throughout this event, roads will remain wet to slushy, with the worst conditions at night into the mornings. Caution is advised.
