Showers, along with a few strong to severe thunderstorms, are expected from the Great Lakes, New England and southward into the Ohio and Tennessee Valleys. In the wake of this system, a stronger storm is expected to track from the Pacific Northwest, Plains and through the Eastern U.S. this weekend. Strong winds, showers and a larger drop in temperatures are expected this weekend into Monday. Read More >
Overview
|
A winter storm brought heavy snow and strong winds to the region on February 4th, 2021. This led to snow covered roads and significant drifting in some areas, along with localized whiteouts. While the snow was heaviest in Wisconsin, the strong winds had a higher impact across parts of northeast Iowa where numerous roads became drifted shut during the afternoon. Travel was not advised in some areas. Ahead of the snow, a mix of freezing rain and sleet also added a light glaze on to untreated roads, parking lots, and sidewalks before the precipitation changed over to all snow during the morning hours. This storm system ushered in sharply colder air leading to an extended period of below normal temperatures and dangerous wind chills. |
