Snow to Continue This Evening - updated 8 p.m.

Snow is expected to continue through the evening before and upper level low swings southeast of Wyoming later tonight.  The snow is anticipated to be moderate to heavy at times this evening, especially across the south-half of the state.  Winter storm warnings and advisories remain in effect for this entire region.  It is expected that a more favorable upslope flow will deepen and allow for increased snowfall rates in Natrona and Fremont counties this evening.  These areas can expect northeast wind of 15 to 25 mph.

Total snowfall of 2 to 5 inches is likely in many lower elevation
locations east of the Continental Divide.  Sweetwater County can anticipate higher amounts of 4 to 7 inches.  The snow will taper off from north to south around midnight tonight.  The graphic at right shows the expected storm total snowfall by early Wednesday.  The highest storm totals are expected in upslope favored locations from around Lander and the south end of the Wind River Mountains eastward across the Green Mountains to Casper and Casper Mountain.  Visibilities are expected to frequently drop to less than one-half mile in the snow and wind.  Falling temperatures should allow for snow to begin sticking on road surfaces this evening.  Travel on Interstate 80, State Highway 28 over South Pass, and along US Highways 20/26 and 287, will be impacted by the snow and wind likely through the Wednesday morning commute.  Visit the Wyoming Department of Transportation road and travel website or call 1-888-WYO-ROAD (1-888-996-7623) or 5-1-1 for the latest road conditions.  Visit our complete webcam listing to view sites across western and central Wyoming. 

The storm system will depart early Wednesday with conditions improving throughout the day.  The coldest air of the season is expected Wednesday night as snow cover and clear skies allow for excellent radiational cooling.  Overnight lows will be 10 to 20 degrees in many of the snow-covered communities.  High temperatures should rebound even more on Thursday and Friday in advance of the next storm system set to hit the area Friday night and early Saturday.
