Temperatures plummet this week
Sunday highs range from the single digits below zero in parts of northern Minnesota to the teens and low 20s southwest:
The Twin Cities metro area should top out around 10 degrees on Monday, then the extremely cold air moves in. The metro area will see high temps in the single digits below zero on Tuesday. Our high on Wednesday is expected to be around -12, after a Wednesday morning low of about -24. The low Thursday morning could also be about -24, followed by an afternoon high around -4. Metro temps finally rise into the positive numbers on Friday, and we could reach upper 20s next Saturday. That’ll feel nice after several days of arctic cold!
