Warming up and getting breezy Sunday as fall season nears
Sunday p.m. highs in the upper 70s-mid 80s plus south winds gusting over 30 mph at times.
A ridge of high pressure amplifies over the Great Lakes region, bringing in a warm airmass over the Upper Peninsula led by a strong southerly wind component.
The high pressure breaks down Monday as a Northern Plains-based system brings widespread rain chances over the U.P. Monday night through Tuesday.
Following the system’s exit Wednesday, a cold airmass builds over the U.P. and brings the chance of Lake Superior-effect rain to mainly the north wind belts.
Rain chances continue next weekend as a low pressure system enters the Upper Midwest.
