Wyoming – Wind rattles signs and pushes dust across highways this morning as winter weather tightens its grip across western and central Wyoming. In Riverton, conditions stay dry early, but the day turns active fast as strong winds and nearby snow create changing travel conditions.
According to the National Weather Service in Riverton, a High Wind Warning remains in effect for parts of southern, central, and northern Wyoming through the afternoon. Gusts could reach 40 mph near Riverton, while Winter Storm Warnings continue in the surrounding mountains. Western valleys remain under a Winter Weather Advisory through early Saturday.
Drivers along US-26, WY-789, and open stretches near South Pass should prepare for sudden gusts, areas of blowing snow, and sharply reduced visibility at times. Snow remains focused on higher elevations, but rain or a rain-snow mix may develop in lower valleys later today, especially as temperatures briefly warm.
By evening, colder air works back in. Any wet pavement could refreeze quickly, raising black ice concerns after sunset. Saturday looks calmer in Riverton with sunshine returning, but temperatures fall into the 20s at night, locking in slick spots where moisture lingers.
Sunday through midweek brings an unsettled pattern. Meteorologists are tracking additional snow chances in the mountains Sunday through Tuesday, with lighter impacts possible east of the Divide. Looking toward Christmas travel, early signals suggest another system late next week that could introduce snow even at lower elevations, though confidence remains low.
This is a good window to prepare. Secure loose items, plan extra travel time, and keep winter gear in vehicles. Winds and mountain snow remain the main threats today, but conditions may change quickly.
More advisories are likely as the pattern evolves. Traveling this weekend? Tell us what road conditions you’re seeing.
