Dangerous Wind Chills Expected Overnight

By  | 

Cheyenne, WY (KGWN) - The National Weather Service has issued Wind Chill Warnings and Advisories for Wyoming and the Nebraska Panhandle through 10 AM Wednesday.

A strong polar high pressure system will continue to drop south and strengthen over the region bringing Wyoming some of the coldest temperatures that will be seen on Tuesday night and Wednesday morning.

As the polar airmass continues to surge southward, temperatures will fall below zero and winds will be breezy from the north at 5-15 MPH. This will send wind chill values as low as -35° over the Laramie Valley and down to -25° across the rest of the region.

With wind chill values as low as -35°, frostbite could set in within 5 to 10 minutes of exposure.

On Wednesday, temperatures will only warm in to the single digits with locations along and west of I-25 struggling to reach 0°. A few locations could see new record low-maximum temperatures. The record low-maximum for Cheyenne is 1° set back in 1916. The Storm Tracker 5 Weather Center's forecast is currently calling for Cheyenne's high temperature to only reach 0°, breaking that previous record by 1°. In contrast, high temperatures in Fairbanks, AK are expected to reach the lower 30's on Wednesday.

In addition to the frigid temperatures, snow will continue to affect areas along and south of I-80 through early Wednesday morning. Another 1-2 inches of snow could accumulate by Wednesday afternoon.
