Region 1

A winter storm is expected to impact the Central Rockies on Thursday with light to moderate snow expected for the higher elevations. This activity will linger across the Rockies through early Friday before continuing eastward. Total snowfall accumulations of 2-4 inches with locally higher amounts in excess of 5 inches will be possible. In addition to the snow, westerly breezes will gust in excess of 30 mph, resulting in decreased visibilities and low wind chills.


As the low continues to progress eastward Thursday into Friday, snow and elevated winds will begin late Thursday and into Friday. Snowfall amounts across Nebraska, the Dakotas, and Minnesota of 6-8 inches with locally higher amounts in excess of 10 inches will be possible. Additionally, strong northerly winds gusting to 40 mph will likely result in blizzard-like conditions, dangerous wind chills, and visibilities below a mile. The main system should exit the region early Saturday morning.

Strong to Severe Thunderstorms Possible Friday across the Mid South
