The National Weather Service (NWS) has issued a winter storm watch for late Saturday night through Sunday afternoon across southern Minnesota. The watch, north and south of the Interstate 90 corridor, does not include the Twin Cities.
Widespread snow totals of 3-6 inches are expected, but a narrow band of 5-8 inches is expected within the watch area. The weather service says there's a little better than 50-50 chance of 4+ inches in the Twin Cities and a 25% chance of 6+ in the metro. Better chances are further south.
Here's the wording from the NWS.
"A winter storm watch for moderate to heavy snow has been issued for southern Minnesota into Wisconsin, along and south of a line from Redwood Falls to Red Wing Minnesota to Eau Claire Wisconsin from late Saturday night into Sunday. The winter storm watch means be prepared, hazardous winter weather is possible.
"Snow will move across southern Minnesota into Wisconsin late Saturday night into Sunday. Most locations will see 3 to 6 inches, but there will be a narrow band of 5 to 8 inches of snow. The heaviest snow will be Sunday morning.
"Travel impacts are expected as roads become snow covered and slippery. Winds will be fairly light, with only minor blowing or drifting."
Minnesota counties included in the watch: Blue Earth, Brown, Cottonwood, Dodge, Faribault, Fillmore, Freeborn, Goodhue, Houston, Jackson, Le Sueur, Lincoln, Lyon, Martin, Mower, Murray, Nicollet, Olmsted, Pipestone, Redwood, Rice, Steele, Wabasha, Waseca, Watonwan, Winona.
The simulated future radar from the NAM model, which shows more snow into central Minnesota than most other models do. The other models keep the heaviest snow just north of I-90 in southern Minnesota, which is what the weather service agrees with at this point.
Snowfall rates of 1-2 inches per hour are expected within the heaviest bands of snow. Fortunately, winds will be light so blowing and drifting shouldn't be much of an issue.
