A band of very heavy snow has migrated closer to the Twin Cities metro area, prompting the National Weather Service to expand a winter storm warning to cover parts of the southwest metro.
At 7:15 a.m. the NWS said: "A line of heavy snow will slowly drift northeast and stall out near the Mississippi River this morning. The heaviest amounts will be southwest of the Mississippi River, with amounts rapidly dropping off northeast of the Mississippi River. Please drive slowly and with caution under this band of snow."
The winter storm warning now includes McLeod, Carver, Rice and Scott counties, where 5-7 inches of snow is expected.
The band of very heavy snow is forecast to keep slowly moving northeast this afternoon, though it will weaken in intensity. Areas in the winter storm warning can expect snowfall rates to reach or exceed one inch per hour.
"Total accumulations of 5 to 9 inches are expected in the warning area with 3 to 5 inches expected in the advisory area. Amounts will diminish quickly near and east of the Mississippi River, although an inch or two are possible into Wisconsin late this afternoon and evening," the weather service said.
Here's how much more snow could fall between 7 a.m. and the end of the storm. Note that areas of southwest Minnesota were already hit hard overnight, so this map is what's to come, not what's already fallen.
