A cold front is bringing snow shower activity to much of the state and will continue to do so through this evening.  Central, northeastern and southwestern Wyoming are under a Winter Weather Advisory through midnight.  The area around  Evanston is under a Winter Storm Warning

through 8PM.  I-90, I-25 and much of I-80 especially from Laramie west will see some snow pack and ice today and tonight.  Meanwhile, northwest and southeast counties will see the least amount of snow.  The southeast however will see a few lighter snow showers later today into tonight.

From the very mild temperatures over the past couple of days, this cold front has brought sharply colder conditions to the state.  Highs today will be mainly in the teens and 20s.  In the south, highs will be in the 30s, but temperatures will continue to fall throughout the afternoon and night.

The weather on Friday will be much more settled.  Expect mostly sunny to partly cloudy skies and cool conditions with highs in the 20s and 30s.
