Winter storm warning in southern Minnesota issued after system slows, heavy snow expected

Things have changed quite rapidly over the past few hours.


The weather service has now added Hennepin, Ramsey, Carver and Washington counties to a winter weather advisory. The winter storm warning (details below) is for a few counties in south-central Minnesota, but locations in the winter weather advisory, including Minneapolis and St. Paul, are now forecast to get 2-4 inches of snow. 

Here's the exact description of what's happening in Hennepin, Carver, Ramsey and Washington counties, courtesy of the NWS: "Total snow accumulations of 2 to 4 inches, with localized amounts of up to around 6 inches possible."


After earlier indications suggested there would be limited impact on Minnesota from today's snow system, things have changed quite rapidly over the last few hours.

A winter storm warning has now been issued in three southeast Minnesota counties, Nicollet, Sibley and Brown, with high snowfall rates expected over a short period of time.

There could be as much as 7-10 inches of snow falling in the space of a few hours Monday afternoon and into the evening.

"The slow moving system will produce snowfall rates of 1 to 2 inches per hour this afternoon and evening," the National Weather Service says. 

"A Winter Storm Warning has been issued for Brown, Sibley, and Nicollet Counties, which will see a couple more hours of heavy snow, and could have 7 to 10 inches by the time the snow ends this evening."

Parts of the south Twin Cities metro is expected to be caught on the edge of the slow-moving, fast-falling system.

This could make for potentially hazardous conditions towards the end of the evening commute.
