Marine Weather and Tide Forecast for Bloomington, MN

DISCUSSION
Issued at 308 AM CDT Tue Aug 4 2026

COOLER AND LESS HUMID NEXT FEW DAYS...The main weather feature of interest is a cold front advancing eastward across the area early this morning. The front has produced scattered showers and isolated thunderstorms across western and central MN. Occasional wind gusts between 35-45mph have been observed with the frontal passage as winds shift out of the northwest. As expected, the broken line of showers and thunderstorms has weakened with eastward movement, which is forecast to continue this morning. We'll keep scattered shower chances around through the first couple of hours after daybreak across southeastern MN and western WI. A chance of showers remains along the MN/IA border this afternoon as the front moves south.
Cooler, more comfortable air arrives as a region of high pressure and drier weather builds into the Upper Midwest. Afternoon highs run below normal, in the 70s, the next couple of days.

WARMING UP LATER THIS WEEK INTO THE WEEKEND...Beginning Thursday highs will return to the lower 80s and continue warming through the weekend. However, the degree of warmth is somewhat uncertain due to the upper-level pattern. By Friday, the Upper Midwest will be positioned within a channel of enhanced northwesterly flow aloft, located between an upper-low over central Canada and an expansive ridge over the desert southwest. Guidance brings a cold front through the region Friday, which may produce scattered precipitation chances. As the weekend progresses, the northwesterly flow pattern will become more westerly/zonal around the ridge, which may support additional precipitation chances, though confidence in timing and coverage is low at this time. This is because there are differences across the ensemble membership with regards to the flattening of the ridge and northward expansion of mid-level warm air over the weekend. For now, we'll roll with highs in the mid 80s Saturday & Sunday.
