Highs will be in the upper 70's to near 80 tomorrow and around 80 on Friday. The dew points should return to the 50's, so Thursday night's lows will be a bit cooler, but there may be areas of fog once again. That means we will get air chilled by its trip over Lake Superior moving into Minnesota tomorrow and especially Friday. The air mass in southern Canada isn't much cooler than what we have now, but the high pressure area over Alberta (see latest NWS WPC North American zoom in map) will change our wind direction to the northeast. Slightly Drier and Cooler Thursday and Friday (Early Fog?)Īfter the front goes by, we will get into slightly cooler and drier air. The better chance will be during the evening, but a few showers might pop up again towards morning as the cold front comes through. The cold front will ease through Minnesota slowly tonight, so there will be a chance of a few showers. We will continue to have uncomfortable dew points in the 60's as is the case this morning (see NWS Aviation Weather Center METAR map). An isolated storm in southern Minnesota may produce some strong wind gusts or some large hail.īefore the storms develop, temperatures will again climb to near or just above 80 degrees. The best chance for rain will be in northern Minnesota, but some of these showers could produce significant rainfall in scattered areas of Minnesota, since the storms will be moving slowly. While the showers have been weakening late at night, the heating of the sun will allow these scattered showers and thunderstorms to redevelop, especially this afternoon and evening. The storms are being produced by that upper-air low near the Canadian border and ahead of the cold front being pushed into North Dakota and Minnesota (see latest NWS WPC North American zoom in map).

More general showers and thunderstorms remained in the Dakotas for much of the night, although they have tended to weaken in the early morning hours (see colored areas getting smaller on the Shortwave Albedo loop from Colorado State satellite slider). Showers and thunderstorms persisted around a small low moving from southwestern Manitoba into northwestern Minnesota this morning. While the wetting for the past few days has only come from late night and early morning fog, there are more showers and thunderstorms on our doorstep this morning (see College of DuPage north central US radar loop). Good Chance of Showers and Thunderstorms, Mainly This PM and Tonight Cloud area and regions to the north and northwest are running at least 25 percent ahead of average rainfall (dark blue) for the growing season. While last week's rains missed much of the area short on rainfall since April 1, from Pipestone to the Twin Cities (still yellow on the middle panel of the Minnesota DNR seasonal percent of precipitation map), the St. However, the change was the bumper crop of small mushrooms, reflecting the recent rains. The thick grass still had trouble drying out from all of our recent rain, and consistent dew points remaining in the lower 60's during the day and the upper 50's at night (see NWS: 72-hours of St. I mowed my lawn yesterday for the first time in a couple of weeks.
