Heads up for potential travel impacts late this weekend into early next week as a low pressure system could affect northeast Minnesota and northwest Wisconsin with freezing rain, snow and rain. Storm track, timing and precipitation amounts to be determined.

One more night of barbaric cold for the Northland with widespread lows in the 20s, 30s and 40s below, and a few of the traditional cold spots in the area could make a run at 50 below zero!
Note: Look how far south the 20s to near 30 below zero temps make it early Thursday morning, possibly as far south as central Illinois, central Indiana and Ohio. Incredible!
Wind chill warning remains in effect until 11 AM Thursday for all of northeast Minnesota and northwest Wisconsin. Stay safe!
Wind chills through Thursday morning of 45 below to around 65 below zero.

Upper level low, polar low, polar vortex…whatever you want to call it has made its way into the eastern Great Lakes today with widespread bitterly cold temperatures stretching from central Canada south to the Midwest and Ohio Valley today. Very impressive shot of arctic air.
RAP model analysis at 5 PM Wednesday showed the core of the coldest air associated with this upper low covering Ontario province with 850mb temps of -32 to -34C. Farther south across the Northland, 850mb temps ranged from -28 to -30C as of late Wednesday afternoon.
A lot of record or near record cold temperatures (Blue dots on map) the past few days across the northern Plains, upper Midwest, Great Lakes and Ohio Valley due to widespread bitterly cold temperatures all associated with the famous Polar Vortex!

Weather Synopsis for Northeast Minnesota and Northwest Wisconsin
The polar vortex of 2019 continues to unleash bitterly cold air across the Northland with highs today only in the teens below zero, which is 30 to nearly 40 degrees below normal for January 30th, absolutely incredible!
Another dangerously cold night ahead under mostly clear skies. Tonight could possibly be the coldest night of this winter with widespread lows ranging from around 30 below to 50 below zero with even a few of the traditional cold spots possibly approaching 55 below by daybreak. With temps as cold as they are it won’t take much wind to push wind chills into the 45 below to 65 below zero range tonight through Thursday morning.

Will start to get some changes on Thursday as winds slowly back to the south as arctic high pressure begins to pull away from our area. Weak warm air advection begins Thursday with 850mb temps of around -25C during the morning, moderating to between -15 and -22C by Thursday evening. With such a cold start to the day we’re still looking at another frigid afternoon with highs in the single digits below to around 10 below zero. Skies will range from partly to mostly cloudy, and there could be a few flurries in spots during the afternoon/evening as milder air begins to push into the upper Midwest.
Warm air advection will intensify on Friday with 850mb temperatures climbing to around zero to -10C, highs on Friday will be in the teens, maybe even around 20 degrees in a few locations.
Note: Easterly winds develop this weekend which could lead to some light lake effect snow or freezing drizzle along the North and South Shore of Lake Superior from Saturday afternoon into Sunday, in addition, a larger storm system could impact the Northland from late Sunday afternoon into Monday with a more widespread wintry mix of precipitation possible at that time. This will be a storm to watch as it could bring significant amounts of ice and or snow to some parts of the area. And behind this system is another one that could impact the area sometime in the Tuesday-Wednesday time frame, should be cold enough for all snow with that one, if it does affect our area.
