Monday snow and mix

Another round of snow will affect central and southern Minnesota Monday through Monday night into early Tuesday.

There’s the potential for light rain, light freezing rain and snow Monday and Monday night in south-central and southeastern Minnesota into parts of western Wisconsin.

The Twin Cities metro area could also see a combination of snow and light rain and light freezing rain Monday and Monday night, ending as light snow Tuesday morning.

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential precipitation pattern from Sunday through Tuesday morning:

NOAA NAM simulated radar from Sunday through Tuesday morning, via tropicaltidbits

The color chart to the right of the loop refers to the strength of the signal that returns to the radar, not to the amount of snow or rain.

Snowfall amounts will depend on the exact storm track and the exact timing of the changeover to all snow.

At this point, it looks like most of the Twin Cities metro area could receive at least two to three inches of snow from Monday into early Tuesday, with a bit more than that in the far northern part of the metro.

Lighter snow amounts are expected in southeastern Minnesota, where it will take longer before they see the changeover from rain and light freezing rain to all snow.
