Scattered showers are possible across northern Minnesota Friday night into Saturday, while mainly dry conditions are expected farther south/east including in Duluth and Superior.
Chances for scattered showers and a few thunderstorms are in the forecast across the entire Northland from Sunday through the middle of next week thanks to an upper level low pressure system and upper level trough which will be over the upper Midwest and Great Lakes. Rains won’t be continuous late this weekend into the middle of next week, but the overall pattern favors the development of scattered showers and perhaps a few thunderstorms (depending on the amount of CAPE/instability) each afternoon and evening from Sunday through at least next Tuesday the way it looks now.
18z NAM 3km model simulated radar forecast valid from 1 PM Friday to 1 PM Saturday shows the potential for a few showers across far northern portions of Minnesota late Friday afternoon into Friday night, and possibly a few showers in northwest Wisconsin Saturday morning, but none of this rain looks widespread or heavy at the moment.
A very wet pattern is setting up across portions of the Midwest and Eastern Great Lakes the next few days.
Total Rainfall thru Sunday morning.
High temperatures in northeast Minnesota and northwest Wisconsin look to mainly be in the 70s to lower 80s Friday through next Wednesday, but there will be a lake breeze at times which will keep temps somewhat cooler within about 10-15 miles of Lake Superior.
Radar loop of the thunderstorms from overnight Wednesday/Thursday morning, June 23-24, 2021 – One line of storms moved through Duluth and Superior around 2 this morning, and this was followed by a secondary thunderstorm which impacted mostly southern portions of Duluth, and all of Superior around 3:30 this morning.
Note: Radar loop time is from 12:05 AM to 3:43 PM.
That second storm which developed behind the initial line produced quite a hail track (mostly small stuff) per radar data as it moved basically along the Carlton & St. Louis County border early this morning.

Here’s a perfect example of what forecasters mean when they call for isolated to scattered coverage rains.
An isolated strong thunderstorm moved through southern portions of Duluth and the city of Superior around 3:30 this morning, but look how variable rainfall totals were with that thunderstorm, ranging from around to less than 0.10″ up at the Airport (north side of Duluth) to over a half an inch in the Proctor and Superior areas.
Some parts of the Northland did pick up a decent amount of rain early Thursday morning, with those blue and purple colors representing rainfall totals of 0.50″ to over 1.00″per radar estimates.
