SYNOPSIS: A winter storm will continue to impact much of western and central Wyoming through this evening with periods of breezy winds and snow.  Snowfall has been weakening throughout the afternoon, and will continue to diminish through the evening hours, before ending late tonight.  Western mountains will likely see snowfall into Wednesday.  Please see the latest winter weather statement for more details.  This storm system is expected to finally exit the area later today as colder temperatures settle in.  Lows are expected to dip into the single to double digit negatives again, for some locations beginning tonight/Wednesday morning. 

IMPACTS:

  • Roads remaining or becoming slick and snow packed over much of western & central Wyoming.

  • Backcountry avalanche danger could increase. Please see Bridger-Teton Avalanche Center for more details.

  • Visibility under a mile at times in snow could result in aviation delays across western and central Wyoming.
