Snow to Increase Saturday in Northwest Wyoming; Very Windy Conditions Expected in the Southwest

SNOW: A winter storm will impact northwest Wyoming through Saturday afternoon. The heaviest snow will occur Saturday morning. As of 5:00 AM Saturday, much of the snow has been confined to areas near the Montana border with 12-22" falling in the northern Absaroka Range. Additional snowfall totals on Saturday will generally range from 4-8" in the mountains. Valley locations may only see 1-3" of snow, with locally higher amounts in northern Grand Teton National Park.

COLD and WIND: East of the Continental Divide the story will be very cold temperatures and gusty westerly wind. An Arctic cold front will keep northern Wyoming in the deep freeze into Saturday morning. This front may briefly retreat north Saturday only to push south again late Saturday afternoon and night. Gusty westerly wind is anticipated ahead of this Arctic front across southwest Wyoming, mainly Sweetwater County. Wind speeds on Saturday will increase to 20 to 30 mph with gusts of 40 to as high as 50 mph.

IMPACTS:

Travel over western and northern mountain passes, primarily Chief Joseph and to a lesser extent Teton and Togwotee, will be difficult at times through at least Saturday.
Gusty west wind will create hazardous crosswinds Saturday on US 189 and US 191 in Sweetwater County.

Model Forecast of precipitation every hour
from 5 am to 5 pm Saturday.
Darker blue shades represent heavier snow.
