SYNOPSIS: A large storm system continues to track west, which will make a significant impact on our weather today and Wednesday.  Out ahead of the cold front, there will be periods of damaging wind across southern and central Wyoming. There have already been several reports of damage associated with these prefrontal winds.

In addition, it will be very dry during the remainder of the afternoon and evening (Tuesday) withextreme fire weather conditions continuing to live up to the hype. There have been several reports of grass fires during the day today with damage sustained to structures.   

The cold front will move into Jackson around 6pm this evening, and will continue to move west to east tonight with snow beginning shortly after frontal passage. Temperatures dropped a degree per minute in some places as the front moved through Utah Tuesday Afternoon.

Accumulating snowfall will occur over much of Wyoming with the heaviest snowfall expected along and east of the Divide tonight and Wednesday. The winds will continue to be strong behind the front with considerable blowing and drifting snow expected, especially at pass level with near whiteout conditions possible at times.

IMPACTS: For anyone traveling, expect snow and wind to create slick roads and difficult driving conditions at times, especially at pass level tonight and tomorrow. Rapidly accumulating snow could produce slushy roads and slow travel along portions of Interstates 80, 90, and 25. 

Those with outdoor interests should also be prepared for much colder, wet, and windy conditions.

The low wind chills, gusty winds, and cold, wet conditions will also have an impact on newborn livestock through Wednesday Night.
