I’ll start with this weather nugget: Minneapolis-St. Paul International Airport received seven-tenths of an inch of snow Friday evening. That brought our Twin Cities season snowfall total to 29.2 inches. That’s 2.7 inches above normal for this point in our snow season.
We’ll be adding to that season snowfall total this weekend.

Most areas have already seen their Saturday high temp. It was 24 degrees around 1 a.m. Saturday in the Twin Cities, and we have fallen through the teens and into the single digits this morning. Parts of the metro area could rebound to about 14 degrees at some point this afternoon. Single-digit daytime highs are expected in much of northern and central Minnesota. Gusty winds will make it feel colder than the air temps.
Sunday highs range from 20s in southwestern Minnesota to single digits in the northeast:
Twin Cities temps will reach the teens by Sunday evening. Metro area temps could be in the lower 20s before sunrise on Monday, followed by falling temps; reaching the mid-teens by Monday afternoon. Twin Cities highs are forecast to be around 3 above zero on Tuesday, followed by mid-teens Wednesday, upper 20s Thursday and lower 20s on Friday.
Tuesday through Thursday look fairly dry in the metro area.
On this date in 1982: The Twin Cities received 17.2 inches of new snow, with another 2.8 inches on Jan. 23. The two-day total of 20 inches brought the snow depth at MSP airport to 38 inches.
