A major Winter Storm is threatening to dump potentially heavy snowfall to Central and Southern Wyoming.
The storm will begin Wednesday night and continue until Mid-day Friday. It appears a low pressure center will track east across South Central Wyoming with a large swath streaming north ahead of it.
Upslope will put the finishing touches on the event. It appears the bulls eye of the storm will be the Casper area with a potential of near 12 inches of snowfall in Casper and up to two feet on Casper Mountain by Friday.
Areas more west will see less snow, but still significant snow will fall with 6 to 10 inches in the Riverton area.
Moderate to heavy snow (Thunder-snow can not be ruled out at this time) creates extremely dangerous driving conditions. Travel could become difficult to impossible at times.
Strong winds will accompany the system creating blowing and drifting snow with possible white out conditions.
Casper - 6 to 12"
Casper Mountain - 20 to 24"
Douglas - 6 to 12"
Riverton - 6 to 10"
Lander - 6 to 10"
Cheyenne - 6 to 12"
Laramie - 6 to 12"
Rock Springs - 5 to 8"
Rawlins - 6 to 12"
Cody - 3 to 6"
Jackson - 6 to 8"
Sheridan - 3 to 6"
Gillette - 3 to 6"
The timing of this storm is beginning to become more clear with the heaviest snowfall occurring between 2 AM Wednesday night through 11 AM Thursday.
Winter Storm Watch is currently in effect for several counties in Wyoming including: Fremont, Natrona, Sweetwater, Albany, Carbon, Laramie, Platte, Goshen, Converse, Campbell, Weston, and Niobrara.
Winter Storm Watch means conditions there is the potential for a significant snow accumulation that may impact travel.
Wyoming history shows Winter Storm Watch turn into Winter Storm Warnings the day of the snowstorm.
Be sure to be prepared and make sure to plan ahead before going out.
