Chilly tonight; warmer weather this weekend into next week

Another chilly night ahead of us as lows fall into the 20s and 30s, although I don’t think will be breaking any record lows Friday morning – See list below

Record Low Temperatures for September 18th

International Falls, MN: 20 F set in 2012

Brainerd, MN: 21 F set in 1929

Hibbing, MN: 22 F set in 2012

Ashland, WI: 25 F set in 1929

Duluth, MN: 29 F set in 1929

Friday’s weather will feature some sun with highs in the 50s to lower 60s. Winds will shift to the south as we get on the backside of an area of high pressure.

Southerly flow increases this weekend resulting in warmer temperatures. Highs Saturday and Sunday are forecast to be in the 60s to lower 70s across the Northland with a breezy S-SW wind 10 to 20 mph on Saturday, and a 15 to 25 mph southerly wind on Sunday.

Not a whole lot of rain in the forecast thru early next week with mostly trace amounts for some parts of the Northland, and this comes mainly late Sunday night into Monday when a few light rain showers are possible.

A closer look at low temps in the Twin Ports from this morning.

Here’s the latest drought monitor update as of September 15th, 2020.

7% of Minnesota is in D1 or Moderate Drought (orange areas on map)

26% of Minnesota is Abnormally Dry (yellow areas on map)

8% of Wisconsin is Abnormally Dry (yellow areas on map) this is down from 16% last week.

Model agreement today continues to be very good regarding next week’s upper level pattern.

Next week still looks warm across the Northland with several days between September 21st-26th having afternoon temperatures in the 70s, and possibly even as warm as 80 degrees!

I’m not seeing any strong model trends for any significant rain events impacting the Northland for the rest of this month.

Fire weather concerns may start to increase across our area over the next few weeks if this very dry weather pattern continues. Note: The last time the Duluth Airport picked up at least a quarter inch of rain was on September 1st (over 2 weeks ago)

Precipitation totals thru the end of the month are forecast to only be around 10-30% of normal for northeast Minnesota and northwest Wisconsin.

Thanks for reading!
