Winds blow arctic chill across MN; some snow Sunday, then colder

The temperature at Minneapolis-St. Paul International Airport hovered around 20 degrees from 1 a.m. to 3 a.m. Thursday.  That’s the high temp that will go into the books for the day.

An arctic cold front moved through Thursday morning, and falling temps are expected, dropping below zero in the metro area sometime Thursday afternoon.

Wind chill temps will be in the range of minus 20 to minus 35 degrees Thursday afternoon and night.

It’s time to switch back to our warmest coats, gloves and hats!

Temperature trends

Cold and colder.

Temps will be falling in most areas today, with some brief pauses.

Lows overnight tonight and early Thursday will range from 30s below zero in far northern Minnesota to teens below zero in the south:

Friday highs will stay below zero in the north, and creep just above zero in the south:

Highs in the teens return to southern Minnesota on Saturday:

Highs retreat a few degrees on Sunday:

After metro area highs in the lower teens on Monday, we could see below-zero high temps on Tuesday and Wednesday.

The last time that our high temperatures were below zero in the Twin Cities metro area was late December of 2017:

National Oceanic and Atmospheric Administration/NWS data for Minneapolis-St. Paul International Airport

That was a memorable cold stretch that began on Christmas Day of 2017 and continued into the first week of January 2018.

Sunday snow chances

It looks like snow will spread across Minnesota as we go through Sunday, and the snow will continue in many areas Sunday night into Monday.

The National Oceanic and Atmospheric Administration’s Global Forecast System model shows the potential precipitation pattern Sunday through Monday:

NOAA GFS precipitation rate (mm/hour) Sunday morning through Monday afternoon, via tropicaltidbits

The color chart to the right of the loop refers to the precipitation rate (mm per hour), not to the total amount of rain or snow.

Other models are a bit slower with the timing, but it looks like the best chance of snow in the Twin Cities metro area will be Sunday evening into early Monday, and we’ll see enough snow to shovel and plow. Check forecast updates.
