A few showers possible tonight and Thursday; turning hot Friday through Sunday, but much cooler near Lake Superior on Friday

Some parts of the Northland will likely get a little rain at times tonight and during the day Thursday (see sim radar forecast below) as we remain under a northwest flow aloft. Isolated thunderstorms are possible as well mainly on Thursday, but the amount of instability, moisture and wind shear needed for stronger storms will be lacking big time, that coupled with poor mid level lapse rates will probably result in only a few weaker thunderstorms with some lightning and gusty winds on Thursday. Due to the added clouds and possible rain showers at times, highs on Thursday will mainly be in the 70s, but areas that see more sun and no rain will likely climb into the 80s.

18z NAM 3km model simulated radar forecast valid from 7 AM Thursday to 10 PM Thursday

Water vapor loop from Wednesday, June 2, 2021 shows the overall pattern pretty well with a strong upper level ridge (heat wave) covering the western US while a couple areas of low pressure lift northeast out of the Southern Plains. Between the two, a northwest flow aloft was in place across the upper Midwest today.

Chances for 90+ degree highs on Friday are greatest in western/southern portions of the Northland and also farther toward the west.

Chances for 90+ degree highs for Saturday increase a bit over a larger portion of the Northland.

Triple digit temperatures continue to look like a pretty good bet in parts of northern North Dakota and northwest Minnesota on Friday.

Widespread 80s and 90s are likely in northeast Minnesota and northwest Wisconsin for Friday and Saturday, with widespread 80s to near 90 degree temps on Sunday. Note: Much cooler temps in the 50s and 60s will be found closer to Lake Superior on Friday as an easterly wind prevails, but a stronger SW wind is expected this weekend which should heat things up even for lakeside locations.

Here’s a look at the high temperature forecast valid from Friday, June 4th through Sunday, June 6th, 2021.

Note: Record to near record warmth is likely in the Northland Friday through Sunday, with daily record high temps and record warm low temps in danger of being tied or broken.

Highest totals around the Brainerd Lakes area where up to a quarter inch of rain fell, but elsewhere rainfall amounts ranged from a trace to <0.10″. Not a big deal.
