A colder-than-usual May closes with one last chill
It’s been an unseasonably cold final week of May across Michigan, with temperatures consistently below average. The typical early June high hovers around 75°F (24°C), but the state is currently experiencing a cold pocket that’s delivering temperatures well below that seasonal norm.
This cool pattern has been driven by upper-level winds around 15,000 feet, circulating a cold air mass over the Great Lakes. The blue and green tones on upper-air forecast maps clearly indicate this cooler-than-normal atmosphere. However, this system is expected to shift northeast, quickly making room for much warmer air coming up from the south.
Early June warmth surges in from the south
By Tuesday, a dramatic shift in weather will sweep across Michigan. Forecast maps show the emergence of orange and red zones, signaling the arrival of above-normal warmth. This pattern isn’t just a one-day event—it’s expected to persist through at least June 12, bringing a summer-like feel to the start of the month.
Beginning Tuesday, daytime highs will leap into the low to mid-80s (28–30°C), with some areas even flirting with the upper 80s (31°C+) during the second half of next week. Southern Michigan will warm noticeably, while northern interior Michigan might still see light frost in low-lying cold spots on Sunday morning, before the big warm-up arrives.
Weekend stays chilly before rapid rise
Before the surge in warmth, Michigan residents will need to endure a chilly weekend. Mornings, particularly in northern parts of the state, could feel quite cold for early June. While Southern Michigan will escape any frost risk, it won’t feel like summer just yet. By contrast, next week looks markedly different, with more days in the 80s than in the 70s, hinting at a strong start to summer for much of the state.
The weather story in Michigan is about to flip dramatically, transitioning from late-spring chills to full-blown summer heat—almost overnight.
