Building a Weather-Ready Nation
Low pressure to the west of Wyoming will keep a moist southwest flow over the state through today. This will bring periods of moderate to heavy snow to much of southwest and central Wyoming. The snow is expected to linger longest across central Wyoming, where snow will likely fall through tonight and even into early Wednesday. This storm system will progress east tonight and Wednesday gradually bringing an end to the snowfall from west-to-east late tonight and Wednesday. Favored locations for snowfall will be upslope areas such as Casper, Casper Mountain, the Lander Foothills, and eastern Wind River Range.

Upslope flow is expected to lay down as much as a foot of snow in South Casper and Lander through Wednesday.

Snow will be moderate to heavy today and even into this evening. The heaviest snowfall will be in central Wyoming from around Lander east to Casper in upsloped favored areas. Northeast wind of 15 to 30 mph will be common today across the region. The exception will be Sweetwater County and the region around South Pass where gusts of 40 to 45 mph will make for reduced visibility in blowing snow.
