Forecast model track

The forecast models are tracking this system through central and northeastern Minnesota into Wednesday. The National Oceanic and Atmospheric Administration’s NAM 3 km model shows this quick-hitting system packing a band of heavy snowfall rates (dark blue) tracking across northern Minnesota overnight into Wednesday morning.

The forecast model loop below runs between 9 p.m. Tuesday and 7 a.m. Wednesday:

As you can see, the green areas favor pretty much all rain for the Twin Cities and southern Minnesota. There will be a little mixed ice (pink) in central Minnesota overnight. The Twin Cities is likely to pick up between 15 one-hundredths (.15) and one-quarter (.25) inch of rain overnight.

Milder by the weekend

Our weather pattern will mellow as we move toward the upcoming weekend. Look for a mix of sun and clouds from Friday through Monday. Highs will reach well into the 40s across the Twin Cities, and we may see more 50s in southeastern Minnesota where snow cover is now fading.
