Minneapolis, Minnesota – Summer heat is expected to strengthen across the Upper Midwest during the final week of July, with above-normal temperatures favored from July 26 through August 1. The Climate Prediction Center indicates a growing likelihood that much of the region will experience temperatures above seasonal averages as a broad ridge of high pressure dominates the central United States.
According to the National Weather Service and the Climate Prediction Center’s 8- to 14-day temperature outlook, the Upper Midwest has a 60% to 80% probability of above-normal temperatures, with the highest confidence centered over the Dakotas and extending into much of Minnesota and Wisconsin. The outlook also includes northern Iowa and portions of Michigan’s Upper Peninsula.
While the outlook does not predict exact daily highs, it signals that afternoon temperatures are more likely to exceed what is typical for late July. Combined with periods of humidity, the warmer pattern could lead to elevated heat index values and increased heat stress during the hottest part of the day.
Cities including Minneapolis, St. Paul, Duluth, St. Cloud, Fargo, Bismarck, Sioux Falls, Eau Claire, Green Bay, and Madison should prepare for a prolonged stretch of midsummer warmth. Residents are encouraged to stay hydrated, take frequent breaks if working outdoors, and check on older adults and those without reliable air conditioning during extended periods of heat.
Although periodic cold fronts and scattered thunderstorms may provide temporary cooling, the overall pattern favors warmer-than-normal conditions through the end of July. The Climate Prediction Center will continue refining the outlook as the period approaches, with additional updates expected throughout the week.
