After a pleasant Wednesday, the short lived high pressure cell that made things that way will go and a new low pressure system from the west will fill the void. After midnight, the void will be filled with clouds and a 70% chance for rain and thunderstorms for about 7 hours or so. Low temps will be 45-50 inland and 40-45 lakeside. The wind will be SSE 5-10 mph.
The showers and isolated thunderstorms should roll away from Minnesota around 7 AM and only a few hours later in Wisconsin and Michigan. That leaves the rest of Thursday to become at least partly sunny. High temps will be 55-62 by Lake Superior and go anywhere from 58 near the Canadian border to 70 in the Twin Ports to 75 in Hayward. The wind will be WNW 5-15 in MN and WSW 5-15 in WI and MI.
Another little slice of high air pressure will force the sky back to clear to partly cloudy as cloud development gets squashed for only one day. Friday’s low will be 40 with a high of 57.
Yet another fresh low pressure system will invade the area on Saturday to bring a mostly cloudy sky and a 30% chance for showers. Saturday’s low will be 38 with a high of only 47. Sunday will be cloudy with low 37 and high 47 with a 60% chance for rain. Monday should be rainy, too, but Tuesday will become partly sunny and the high temp will return to the upper 50’s. That’s only about 5 degrees cooler than normal.
