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."
4 P.M. UPDATE
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.
