A heads up for next weekend (April 13-15)
Not sure yet if this storm will hit Duluth or not, but if we don’t get any snow or rain out of it, the potential for high winds out of the east is certainly there from next Friday night through Sunday morning with potential for wind gusts of 45-55 mph!
Note: The Duluth Airport still hasn’t had their first 50 degree temperature this year. Listed below are the average first dates for 50, 60 and 70 degree temperatures using 1981-2010 climate data.
Average first date for 50 F: March 18
Average first date for 60 F: April 8
Average first date for 70 F: April 21
Note: Last year, the first 50 was on February 17, first 60 was on April 8, and first 70 was on
April 15.

Weather Synopsis
This is about as cold of an airmass you’ll ever get during the month of April! What a day for cold weather fans. The upper level winds are blowing from NW-SE with 500mb temperatures as low as -42C north of Lake Superior late this afternoon per SPC meso-analysis page. 850mb temps around -18C across the Northland, that’s cold for January, just plain ridiculous for April!
The good news about this time of year is that the frigid temperatures won’t stick around long, but the temperatures ahead for this weekend aren’t exactly balmy, in fact they are still well below average for early April, and Duluth likely won’t have an above freezing temperature until Monday, slight chance will get there Sunday. Every day so far this month has been below freezing at the Duluth Airport.
A strong area of high pressure will be in control our weather through the weekend which will lead to clear to partly cloudy skies in our area through Saturday night followed by increasing cloudiness for Sunday.
Lows tonight will range from the single digits below to teens above zero, highs Saturday and Sunday in the 20s to lower 30s.
On Sunday there will be an area of low pressure that’ll track southeast out of the northern Plains, most of the snow associated with that system should remain west/southwest of the Northland, but some light snow could eventually spread into southern portions of our area especially Sunday afternoon or Sunday night but snowfall amounts look like they will be less than an inch.
