Winter storm watches and warnings for much of southern MN Tuesday

The latest computer model information shows snow is likely over much of central and southern Minnesota from Tuesday afternoon into Tuesday night and early Wednesday.

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential snow pattern, caused by a low-pressure system passing to our south:

The heaviest snow is expected over far southern Minnesota, where the National Weather Service has issued a winter storm warning that runs from Tuesday into Wednesday:

Scott and Dakota counties in the southern part of the Twin Cities metro area are in a winter storm watch from noon Tuesday through Wednesday afternoon due to the potential for 6 or more inches of snow.

The northern part of the Twin Cities metro area may see only 2 or 3 inches of snow, with around 4 inches in Minneapolis and St. Paul and 5 or 6 inches in much of the south metro.

Rain could be mixed with the wet snow at times.

If the low-pressure system tracks a bit more to the north, the heavy snow area will shift north.

Here is the National Weather Service snow potential map and snow timeline for Minnesota:
