Note the spin that dropped south through northeast Minnesota today per water vapor satellite loop - This helped to develop the scattered thunderstorms in our area this afternoon.
















Here's the potential pattern that is setting up for next weekend into early the following week.

Weather Synopsis

Overall this weekend wasn't bad at all, certainly a lot better weather than what the computer models were showing earlier in the week.

The weather changed quite a bit today especially near Lake Superior thanks to a potent boundary which swept SW down the big lake during the day with winds shifting from NW to NE as that boundary moved through, temperatures fell some 20 to 30 degrees in a matter of minutes once that wind shifted directions (Temps went from the 80s to 50s)

Elsewhere across the Northland temperatures today were generally in the 70s and 80s with cooler temperatures in far northeast Minnesota due to more clouds and scattered showers.

Scattered showers and thunderstorms have been moving south/east through parts of northeast Minnesota and northwest Wisconsin this afternoon with heavy downpours, lightning and a few isolated instances of small hail reported with this activity.  This convection was caused by a potent little disturbance which dropped south out of Ontario Province today.

Lingering spotty showers and storms this evening will give way to generally dry conditions across the Northland through Tuesday.  The upper low currently moving through our area this afternoon will exit to the south/east later tonight which will be followed by high pressure that will build into the upper Great Lakes through Tuesday.

One thing we may see is areas of low clouds/fog develop over Lake Superior during the next few days, and some of this could spread inland at times through Tuesday morning thanks to an E/NE wind direction, otherwise expect generally partly cloudy skies from late tonight through Tuesday.

Temperatures will remain on the mild side away from Lake Superior with highs Monday and Tuesday in the 70s to lower 80s.  Near Lake Superior highs will mainly be in the 50s.

Lows tonight and Monday night are expected to be in the 40s and 50s.

Note:  The next chance for some showers comes Wednesday-Thursday as a low pressure system moves through the area.

Forecast for Duluth and Superior

.Tonight...  Partly to mostly cloudy.  Some low clouds or fog possible late.  Low 45 to 50.  Wind east to northeast at 10 to 20 mph.

.Monday...  Areas of low clouds or fog possible mainly in the morning otherwise partly cloudy.  High 64 to 69 but cooler near Lake Superior.  Wind east at 10 to 20 mph.
