Extreme weather swings hit the Northland earlier today, with Ashland, Wisconsin experiencing a chilly low of 35 degrees this morning, while Brainerd, Minnesota saw nearly an inch of rain, recording 0.92 inches.
A mild and mostly dry Labor Day weekend is on tap for northeast Minnesota and northwest Wisconsin, with afternoon highs generally in the 70s, though some spots may near 80 degrees. Nights will be comfortably cool, dipping into the 50s with occasional 40s. Patchy fog could form late at night and linger into the early morning, and there’s a chance of a passing shower, but no widespread or prolonged rain is expected through Labor Day.
The next big weather system to impact the Northland comes in the middle of next week as a mid- and upper-level trough intensifies across the region, with the 500 mb trough potentially dipping to around -2 to -3 sigma next Wednesday or Thursday, according to the GFS model.
Cooler air is expected to arrive later next week with this system, bringing a chance for highs to remain in the 50s from Wednesday through Friday, and potentially even staying in the 40s in some areas.
Rain is expected next Tuesday and could stick around into Wednesday as a cold front and upper trough pass through the area. Additional showers might develop later in the week, around Thursday and Friday, with another reinforcing cold front moving through the region.
Most of the widespread rain this weekend will be concentrated in parts of South Dakota and Nebraska, where some areas could receive 2 to 5 inches or more by Sunday evening, with some higher-end totals possibly reaching double digits.
If any rain develops in northeast Minnesota and northwest Wisconsin this weekend, it should stay fairly isolated.
