Looks like we could also get some rain on Friday to go along with the milder temperatures later this week.
21z HRRR model
North Central U.S. hazards map; Wind and fire weather concerns in parts of the region for this evening.
Gusty winds over North Dakota late this afternoon, should have similar wind gusts here in the Northland by later this evening.
21z RAP model. 500mb Vorticity forecast through Noon Tuesday. That is one impressive looking vort diving S/SE out of southern Canada and through the Northland later tonight, exiting to the southeast Tuesday morning. Some of the stronger wind gusts may occur as this vort moves through.
…An active weather pattern through the weekend but no major impacts at least with significant amounts of precipitation as the main storm track stays north of our area…
Colder temperatures return Tuesday after a one day break. To usher in this next cold airmass is a strong surface low (988mb) which will track east as it passes just north of Minnesota and Lake Superior tonight and Tuesday morning. A strong cold front attached to this low will sweep through the Northland this evening which will be followed by shifting winds from SW to NW, strong cold air advection and strong pressure rises — This all leads to gusty winds beginning later this evening and lasting into Tuesday. Wind gusts of 25 to 35 mph are likely with a few gusts over 40 mph!
There could be a few flurries or snow showers over parts of the area tonight and Tuesday morning but for the most part dry weather continues through Wednesday morning.
Lows tonight will range from around 10 above to the lower 20s with highs Tuesday in the teens and 20s.
Note: A weak system could bring a little bit of snow to parts of the Northland Wednesday afternoon or evening but shouldn’t amount to much. Warmer temps return later in the week with the warmest day looking like it’ll be on Friday, but another strong area of low pressure passing by to our north could bring some rain to the area for Friday which could change to a little bit of snow Friday night or Saturday as another shot of colder air moves in.
