Whiplash: Arctic chill today, 40 degrees warmer Friday

Your backyard thermometer gets a good workout this week.

Temperatures plunged to -24 this morning in towns like Hallock in northwest Minnesota. The Twin Cities flirted with the zero mark for the first time in more than 3 weeks when we bottomed out below zero on January 13.

Arctic high pressure lingers over Minnesota for another 36 hours. Temperatures will actually begin rising Thursday night into Friday morning as southwest winds return milder air into our region. A shot of light snow hits northern Minnesota Friday, while red dashed lines signify warmer Pacific air invading southern Minnesota.

Warm pattern returns

After our brief Arctic interlude, the maps favor a return to warmer than average temperatures for the next 1-2 weeks. The upper air charts show another mild Pacific flow developing the weekend of Feb 18-19.

Temperatures in the 30s, with several days at or above 40 degrees are likely in the next two weeks. Starting Friday, temps run a good 10 to 15 degrees warmer than average for 1-2 weeks.

The numbers confirm, winter remains a relative, fleeting concept in Minnesota this season.

Out like a lamb?

Our recent trend of milder, shorter winters looks likely to continue this season. NOAA's longer range 3-4 week outlook favors milder than average air right into early March. Will the early bird golfers be out in mid-March this year?
