At the moment it looks like the heaviest rainfall could setup just south of the Brainerd Lakes area and northwest Wisconsin for Saturday night but some rain is still expected in these areas, and of course things could change as to where the heaviest corridor of rain sets up for Saturday night. Stay tuned. Source, Weather Prediction Center.

July 20: 98 degrees set in 1901
July 21: 93 degrees set in 1960
July 22: 95 degrees set in 1941

Spotty showers will continue this evening with dry weather overnight. Partly to mostly cloudy skies with lows in the 50s with 40s in the typical cold spots. Winds variable to east at 5 to 15 mph.
Saturday (July 16)
High pressure will move off to the east tomorrow as low pressure moves into the western High Plains and northern Plains -- Warm and moist air will be lifting north into the Upper Midwest out ahead of this system and that combined with a strengthening low level jet to around 30-35 knots will cause some showers and thunderstorms at times tomorrow and tomorrow night.

Showers and thunderstorms are possible on Sunday as an area of low pressure moves through the Upper Midwest along with a warm front and cold front. At this time it looks like the greatest instability/potential for a few severe thunderstorms will be to our south but with a muggy airmass in place locally heavy rainfall will be possible in parts of the Northland. Highs on Sunday are expected to be in the 70s to around 80 degrees.
Dry weather returns on Monday with highs in the 60s and 70s.
