All at once, we’ve returned to the September-like weather that has been almost a constant in our region this summer thanks to the passage of a cold front through the Upper Mississippi Valley Monday, and just like that the heat wave is over. A crisp north breeze will drawing in some dry air from northern Minnesota and Canada today and that looks to stay for just a little while longer as our “active” weather pattern continues as another storm system to the west may be bringing more changes for the tail end of the week. We’ll likely stick with the 70s for high temperatures regardless of what’s happening with our weather this week, but it does appear that a little more humidity will be working its way in for Thursday as a storm system arrives from the southwest. There will be a chance for more than an inch of rainfall associated with that system for much of the area for that one day with just hit-and-miss shower chances surrounding it late Wednesday and then again during the day Friday along with a little more sun at times.
Overall, the upper level pattern will remain in a flat “zonal” flow more or less, meaning our temperatures will likely stay in a seasonable range with mid to upper 70s and the occasional lower 80s possible through the end of the week and much of next week.
The jet stream lies just to our north, keeping late August to early September temperatures around while a series of storm systems will riding through our part of the region off and on through the next week.
A storm system and its associated cold front will ride along the jet stream bringing a chance for scattered showers and thunderstorms to the local weather picture for much of Labor Day Monday. Behind it, seasonable 70s appear likely for the first week of classes in most Minnesota school districts.
