Nov. 9 Winter Storm (Forecast #1)

This is forecast #1 for the winter storm possible on mainly November 9th across MN/IA/WI. For now, looks like through Midnight, snow flurries to some moderate snow could occur in SD and in southwest MN. Otherwise rain and rain/snow mix in northwest Iowa. As we head overnight, heavier precip should fall throughout SD and into IA/MN. It should remain as mostly rain through IA, with mainly snow in MN and heavier snow possible in SD. By sunrise the snow should make its’ way into northern IA and also start to become heavier in MN/WI. Continuing through the noon hour heavier snow should begin throughout the northern 2/3rds of Iowa as well as southern MN and all of WI, that should continue through most of the afternoon and evening possibly. By tomorrow night we should see the snow taper off in all but WI…

Potential Snow Amounts:

Pierre, SD: 0-1 Inch
Aberdeen, SD: 0-1 Inch
Sioux Falls, SD: 0-1 Inch

Pipestone, MN: 0-1 Inch
Minneapolis: 0-1 Inch
Mankato, MN: 2-4 Inches

Sioux City, IA: 0-1/2 Inch
Ft. Dodge, IA: 1-2 Inches
Waterloo, IA: 1-2 Inches
Dubuque, IA: 0-1/2 Inch

LaCrosse, WI: 4-6 Inches
Wausau, WI: 4-7 Inches

As you can see, heavier snow amounts will likely be found in southeastern MN and into WI. Otherwise, a big mix of precip will be found across Iowa, as you could see quite a variance in the amounts forecasted depending on how quickly it turns over. Difficult forecasting situation, but definitely worth the watch as some areas of the northern plains are likely to see their first significant snowfall.
