This winter storm isn’t over yet. It’ll continue to drop heavy snow in parts of northern Minnesota and northwestern Wisconsin Sunday and Sunday evening.

The official Saturday night snow total at MSP airport was 1.1 inches. Some spots in the north metro, including Blaine and Champlin, reported 2 inches. I saw a tally of 3.7 inches in St. Cloud and 7 inches in Wadena and Crookston. A few totals over 8 inches are showing up in northwestern Minnesota and I notice a recent report of 11 inches from near Erskine, in Polk County of northwestern Minnesota.

Snowfall reports will be updated by the NWS here.

This is how the NWS snow map looked at 10 a.m. Sunday:

You can hover over any data point on the linked NWS snowfall map to see the location and time of the snow measurement. You can also slide the map to see snow reports in other parts of Minnesota and Wisconsin.

We may see some double-digit snow totals in northeastern Minnesota by Sunday night.

Many locations in Minnesota and northwestern Wisconsin reported slippery spots on roads or snow-covered roads Sunday morning. Blowing snow will also reduce visibility today and tonight as winds ramp up. Updated Minnesota road conditions can be found here. Wisconsin road conditions can be found here.

Heaviest snow to the north today

The Twin Cities metro area could see occasional light snow showers or sprinkles today and this evening, but additional snow accumulation will be minimal in the metro area.

Snow will continue to accumulate in northern Minnesota and parts of central Minnesota plus much of Wisconsin today and this evening. The National Oceanic and Atmospheric Administration’s High-Resolution Rapid-Refresh (HRRR) model shows the potential precipitation pattern from noon Sunday to 6 a.m. Monday:

NOAA’s North American Mesoscale (NAM) forecast model shows a similar precipitation pattern.

Notice the tight spacing of the isobars today and tonight, which indicates strong winds.

Parts of northwestern and north-central Minnesota will see a few more inches of snow today, but additional snow amounts will be highest in northeastern Minnesota:

Temps plummet Sunday night, then arctic chill on Monday

A cold front will deliver much colder temps Sunday night. I recommend that you shovel your sidewalk or driveway Sunday afternoon. Whatever slush or water that is left there overnight will flash freeze as temps plummet.

Single-digit daytime highs are expected Monday in northern Minnesota, with mainly teens in the south. Our Twin Cities metro area will have a Monday high in the upper 20s around 1 a.m., followed by falling temps. Metro area highs during the daylight hours of Monday are expected to be in the low to mid teens.

Your warmest coat, gloves and hat will feel good Monday morning. Look at these Monday morning wind chills:

Twin Cities metro area highs are projected to reach the lower 20s Tuesday, then around 30 Wednesday followed by upper 30s Thursday and mid 30s on Friday.
