Original story

Snow is likely to pile up in the southern half of Minnesota again this week as multiple storm systems are expected to move through the Upper Midwest. 

"Accumulating snow is likely across much of southern MN into west central WI late Tuesday night through Wednesday," says the National Weather Service (NWS) Twin Cities. "Snow totals of 4+ are possible over south central and east central MN into west central WI."

Here's a better map that shows the chances of any given area receiving 2+ inches of snow and 4+ inches of snow.

"Snowfall is expected to spread into Southern MN Tuesday night and reach the I-94 corridor of central MN and West Central WI by Wednesday morning. An inch or two accumulation is likely by 6 AM for the Wednesday morning commute," the NWS Twin Cities says.

"Snow will continue through much of the day, with the heaviest Wednesday morning with snowfall rates near 1 inch an hour possible. It will taper-off from Western MN to Western WI late Wednesday afternoon and evening."

The storm system is still nearly 72 hours away so don't write home about any snowfall predictions just yet, but amounts will likely be plowable where the heaviest snow falls. 

Here's one computer model (NAM 12KM) that shows snow arriving from southwest to northeast after 9 p.m. Tuesday.

AccuWeather is predicting a wide swath of 3-6 inches, including in the Twin Cities, with the heaviest snow totals, 6-12 inches, in Iowa and extreme southern Minnesota. 

"Snow looks to impact travel Tuesday night into Wednesday across most of the local area," says the NWS La Crosse, which covers southeast Minnesota, northeast Iowa and southwest parts of Wisconsin. 

"At this time, snow accumulation of 3 to 6 inches appears likely by late Wednesday afternoon, but the snowfall forecast could change with any shifts in the storm track."

Once Minnesotans dig out of Wednesday's snow they'll get a short break on Thursday before another system moves through the region Friday and Saturday, and then another storm could be on its heels later in the weekend into early next week.
