This is likely the coldest 24 hours of winter. Our current subzero air mass early this week is very likely the coldest air we’ll feel this winter. Wind chill readings are still in the 40s below zero across northern Minnesota Monday afternoon.

The forecast maps through the end of January suggest we may dip below zero briefly one more time, but nothing this cold is in the forecast. And rapidly increasing daylight in February makes it much harder to see teens below zero in the south. 

So Monday’s low temperatures of minus 14 degrees at Minneapolis-St. Paul International Airport, our subzero high temperature, and Tuesday's likely low around 17 below zero, will very likely be the coldest 24-hour run of the winter. 

Northern Minnesota saw temperatures in the 30s below zero and a few 40s below zero Monday morning. 

Here are some select minimum temperatures from across Minnesota on this Martin Luther King Jr. Day:

High temperatures are still below zero Monday afternoon. That sets Minnesota up for the coldest night of this cold snap Tuesday morning. The Twin Cities will bottom out around minus 17 to minus 18 degrees around sunrise Tuesday. 

If we hit 17 degrees below zero at Minneapolis-St. Paul International Airport, it will be the coldest temperature there in three years. The last time we were as cold was Jan. 7, 2022, at minus 17 degrees. The last time we hit minus 18 degrees in the Twin Cities was on Valentine’s Day of 2021.

Temperatures will recover above zero across most of Minnesota Tuesday afternoon.

Highs will return to the 20s by Wednesday.
