Mild weekend temps; heavy snow for Missouri, Illinois and southern Iowa

We’re looking at a lot of bare ground in the Twin Cities metro area. There’s a bit of snow on north-facing hills and in shady areas, but we don’t see a typical January landscape when we gaze out of our windows.

The season snowfall total at Minneapolis-St. Paul International Airport is sitting at 11 inches right now:

National Weather Service

We’re running 14.8 inches below normal for snowfall at Minneapolis-St. Paul International airport to this point in our snow season. Snow-lovers take heart, we’re only about half-way through our typical snow season.

There’s plenty of snow on the ground in central and northern Minnesota, as depicted on the latest Minnesota snow depth map from the Minnesota State Climatology Office:

Winter storm to the south

St. Louis has tallied 6.9 inches of snow this snow season and could see an additional 6 to 10 inches of snow from Friday afternoon through Saturday afternoon, pushing the city’s season snowfall total ahead of our Twin Cities season total!

A developing winter storm has prompted the National Weather Service to issue winter storm warnings from Missouri to southwestern Ohio:
