Wintry mix changed to heavy snow this afternoon; looking ahead to round two

A mixture of cold rain and snow changed to snow in western and central Minnesota this afternoon with the accumulation of several inches from Alexandria to Brainerd, including a report of 6.5 inches of snow at Millersville in Douglas County, northwest of Alexandria.

Snow will spread northeast the remainder of the afternoon, but is expected to taper from west to northeast this evening. Snowfall totals of 4 to 6 inches are likely from near Grand Rapids to Duluth and Hibbiing.

From the National Weather Service in Chanhassen at 220 p.m. CST:

STATE PATROL REPORTED THAT A SEGMENT OF THE SOUTHBOUND RIGHT LANE OF HIGHWAY 169 HAS BEEN CLOSED JUST SOUTH OF ST PETER DUE TO A MUD SLIDE.

In the greater Twin Cities Metro area, rainfall amounts have approached a half inch since the rain began late last night.

A cold front was tracking southeast through the state and will usher in cooler air during the overnight hours. The front will stall over northern Iowa on Sunday. Another low pressure will move along the front from Missouri on Sunday.

Heavy snow may develop over southeast Minnesota on Sunday night into Monday.

I’ll keep an eye on the path of the next system and have an update for you here on Updraft on Sunday morning.
