Rochester, Minnesota, is heading from spring warmth back toward a sharp cool-down Friday as a potent cold front may bring severe weather chances to the Upper Mississippi Valley. High temperatures could fall by 30 degrees from Friday to Saturday, ending a week that had already climbed into the 60s and 70s.
That swing fits a month that has already bounced from early-April highs in the 30s and 40s to later stretches in the 50s and 60s, then to this week’s warmer spell. Next week is expected to bring mainly 60s for highs, which would run five to ten degrees above the seasonal average, and those temperatures may linger into the final few days of April.
The pattern matters because Friday’s front is not just a temperature change. It is the point where mild weather gives way to the kind of fast-moving shift that can bring severe weather chances, even as the rest of the month stays on the warmer side of normal. For Rochester, that means residents should be ready for a notable break between Friday and Saturday, then a quick return to more seasonable April conditions after the front passes.
Looking ahead, the Climate Prediction Center’s latest outlook for May points to a typical month, with temperatures and rainfall expected to be normal across the region. For Rochester, normal May weather means highs in the upper 60s and about 4.35 inches of rainfall, so the bigger story after this week’s swing is that the region is expected to settle back toward average as April ends and May begins.
The question now is not whether the weather will change again. It will. The real issue is how much trouble Friday’s front creates before the forecast settles into a more routine spring pattern.
