MARSHALL — A storm system could bring the potential for heavy snow in the Dakotas and Minnesota in the next few days — but it doesn’t seem likely that the Marshall area will see big accumulations, the National Weather service said Tuesday.

The weather service was reporting growing confidence that a large storm system will affect the region tonight through Friday. The storm system comes with a chance for cold, strong wind and heavy snow, especially in South Dakota and North Dakota.

In the Marshall area, snow accumulations from the storm will likely be an inch or less, said NWS meteorologist Jim Murray. The heavier snow is forecast to fall in central South Dakota and move into northeastern South Dakota more than Minnesota, he said.

Precipitation in the Marshall area will likely start out with rain and isolated thunderstorms late tonight and into tomorrow, Murray said. Starting around Thursday night or early Friday morning, the rain will change over to snow, with light snow continuing into Saturday.

Conditions in the Marshall area are also going to be windy and colder over the next few days. On Friday, winds are forecast at speeds of 25 to 30 miles per hour, with gusts up to 40 to 45 miles per hour, Murray said. Temperatures are forecast to fall into the high 30s on Friday, but they might warm up to around 40 degrees by Sunday, he said.

There are still chances that predicted weather conditions will change between now and Friday, Murray said.
