MARSHALL — Severe winter weather will be lingering in southwest Minnesota this weekend, with high wind gusts, ice and heavy snow expected. While it’s still not certain how much snow and ice will accumulate in the area, Lyon and Lincoln counties are both included in a winter storm warning that will last until 6 a.m. Monday, the National Weather Service said.

The winter storm warning forecasts total snowfall of anywhere from six to 14 inches, and ice accumulations of up to a quarter-inch. The Marshall area could receive four to six inches of snow through Sunday, but those numbers aren’t certain, the NWS said. Southwest Minnesota was also in an area with high risk of ice.

Winds on Sunday could gust as high as 40 miles per hour, creating areas of blowing snow and reduced visibility. The winter storm warning said power outages and tree damage due to ice are possible, and travel could be “nearly impossible.”

In the Marshall area, forecasts call for snow mixed with sleet and possibly freezing rain, which would start falling Friday night. The NWS said the storm system moving through the Dakotas and Minnesota will come in more than one wave, with a possible break in the precipitation today. The worst conditions, with freezing rain and blowing snow, are expected to hit tonight and continue through Sunday night.

The NWS said ice accumulations of anywhere from one-tenth of an inch to a quarter inch could be seen in southwest Minnesota this weekend. Elevated surfaces like power lines and trees, and structures like roads, bridges and overpasses are at most risk for ice formation. However, some areas in the region could see temperatures get above freezing on Saturday, which could help improve icy conditions for a short time.

The wintry mix in the Marshall region will start changing to snow and blowing snow late Sunday night, the NWS said. The blowing snow could last through the day Monday.
