More winter weather on the way
6-12 inches of new snow
January 11, 2007
The National Weather Service out of Riverton has issued a Snow Advisory for Yellowstone National Park, and the Teton and Gros Ventre mountains. The advisory is in effect through 5PM Thursday. North central Wyoming is also under a Snow Advisory through Thursday.
A strong arctic cold front will move across central and western Wyoming through Thursday. Periods of snow will develop, initially across far northwest Wyoming and then spread across north central Wyoming. Snow accumulations are expected to be up to 6 inches in the lowest elevations and 6 to 12 inches in the higher terrain by the end of the day on Thursday.
Roads and highways will become icy and extremely slick, especially during the morning commute into the weekend.
Strong northeast winds will develop behind this cold front, especially over South Pass, the Red Desert, the Interstate 80 corridor and across the southwest corner of Wyoming. These strong northeast winds combined with snowfall may make travel treacherous Thursday and into Friday.
Well below average temperatures will occur Friday through the weekend as the Arctic air becomes entrenched over the region. Overnight lows will likely plummet well below zero in many locales Saturday and Sunday mornings. Overnight lows Saturday and Sunday morning will likely range from -10 to -20 below zero in the east and mountain locations with -25 to -35 below zero across the far west valleys and basins.
Anyone with outdoor plans Thursday into the coming weekend should be prepared for harsh winter weather conditions.
