You'll want to do your sledding and cross country skiing this weekend, because snow conditions will deteriorate during the coming week.

Ice and snow on Monday

A low-pressure system will spread moisture over Minnesota and western Wisconsin on Monday.

With surface temps slightly below freezing and warmer temps aloft, a mix of freezing rain, sleet and snow is possible on Monday, changing to mostly snow by Monday evening.

The National Oceanic and Atmospheric Administration’s Global Forecast System model shows the potential mix of precipitation:

NOAA GFS model precipitation Monday through Tuesday morning, via tropicaltidbits

In the forecast loop, blue areas are where the precipitation is likely to be snow for that time in the loop. Purple areas are sleet or freezing rain. Green areas are likely to be rain, but the rain could freeze at ground level if surface temps are cold enough.

The color chart on the lower right of the loop refers to the strength of the radar signal returning to the radar, not inches of snow!

In the Twin Cities metro area, we could see one-quarter inch of ice accumulation on Monday, and several inches of snow from Monday into early Tuesday.

The National Weather Service has issued a winter storm watch from southwestern and south-central Minnesota through the Twin Cities metro area and Isanti and Chisago counties:

In east-central Minnesota and the Twin Cities, the winter storm watch runs from 6 a.m. Monday to noon Tuesday.

In south-central Minnesota, the watch goes from midnight Sunday night to 6 a.m. Tuesday.

In far southwestern Minnesota, the winter storm watch starts at 6 p.m. Sunday and continues through Monday evening.
