It's going to be way below zero tonight – but a warmer weekend is coming

Do thermometers go down to 30 below? Northwestern Minnesota may find out.

A week that saw Minnesota roads covered with ice and blowing snow more than once is finally nearing an end. But not until temperatures fall well below zero.

Not just a degree or two below. Forecasters are warning that Friday morning will see temperatures in the double digits below zero even down in Albert Lea. The coldest spots will be in northwestern Minnesota, where minus 30 is possible. And we're talking about the air temperature, not the wind chill.

The harsh weather has already taken hold in the Red River Valley, where winds created blizzard conditions on Thursday. And it'll stay windy overnight while temperatures drop into the 20- to 30-below range. That's why the area from Fargo-Moorhead up to the Canadian border is under a wind chill warning until noon Friday.

The National Weather Service says at 6 a.m. wind chills in the northwest will range from -30 to -50. When it's that cold, exposed skin will freeze in 10 minutes, they say.

The rest of Minnesota won't have it quite as bad, but that's not saying much.

Instead of a wind chill warning, there's just an advisory for the middle of the state, including the Twin Cities. Wind chills are not likely to get more than 25 below zero. As for the temperatures, there are lots of big negative numbers on the map:

Warmer temps are coming!

But here's the nice thing about this bit of nasty cold: it's only lasting a day – or less – and then we get rewarded with a warm front.

The Weather Service office in Duluth says a "major pattern change" will move in Friday afternoon, bringing warm air that will keep highs in the upper 20s and lower 30s through next week.

AccuWeather expects the Twin Cities to reach 20 degrees (above) by Saturday and 30 by Monday, with a January thaw arriving by the end of next week.

Something to look forward to when we 're facing those way-below-zero wind chills Friday morning.
