SE Wyoming Could See -30 Wind Chills, Heavy Snow This Week

The Cheyenne Office of the National Weather Service continues to warn Wyoming residents about an approaching arctic front that could bring wind chills of as low as -30 to some areas this week.

The agency is also warning about up to three feet of snow in the Sierra Madre and Snowy Range mountains. Cheyenne is included in a winter storm watch [see map below]. Laramie, at last report, was just outside of the watch area, but that is subject to change.

The weather service emailed a statement on Monday evening about the approaching front:

High Wind Warnings/Watches across the area: Strong winds on Monday night through Tuesday afternoon across SE WY and the Nebraska Panhandle.  Moderate

• 65-85mph wind gusts likely over the wind-prone corridors of SE WY, and 60-65mph wind gusts possible over the Nebraska Panhandle.

• Arctic air behind a strong cold front on Wednesday will cause bitter cold temperatures and wind chills below zero to occur by Thursday morning.  Moderate
