Hot temperatures grip Southern Michigan this week
Southern Michigan is currently in the grip of intense heat, with the rest of the state experiencing relatively warm conditions as well. The latest long-range forecast, updated on June 19, offers insight into whether this extreme heat is expected to linger throughout the summer.
According to NOAA’s Climate Prediction Center, there is now a moderate chance that July, August, and September will bring temperatures above seasonal averages across Michigan. This projection doesn’t guarantee unrelenting heat but suggests a leaning toward warmer-than-usual conditions statewide.
Michigan summer expected to run warmer than usual
Historically, average high temperatures during July and August in Michigan range from about 80°F (27°C) in the north to 83°F (28°C) in the south. By September, highs typically drop into the 70s°F (21°C to 26°C). This summer, however, models point to more frequent afternoon highs between 85°F and 95°F (29°C to 35°C), with occasional stretches in the low to mid-90s°F (32°C to 35°C).
This week’s heat wave in late June might act as a precursor to hotter conditions in July, particularly if humidity levels stay elevated. While another extreme heat wave isn’t forecast for early July, temperatures flirting with 90°F (32°C) will likely pop up occasionally throughout the month.
The broader U.S. trend: a warm summer coast to coast
This warmer-than-normal pattern isn’t isolated to Michigan. In fact, the entire United States is leaning toward above-average temperatures, with South Florida, the Northeast, and parts of the Mountain West showing a much stronger signal for persistent, hotter-than-normal weather.
Rain outlook: no dominant pattern, but storms possible
While the temperature trend is more defined, the precipitation forecast for Michigan between July and September is more uncertain. The long-range models show no clear signal, which meteorologically means that no persistent drought or wet pattern is expected across the region.
To the west of Michigan, drier conditions are more likely, while to the southeast, wetter-than-normal weather is projected. However, local heavy rainfall events remain a possibility, especially if hot, moist air masses set up just south of the state.
An example of this played out on Saturday morning, when a few isolated thunderstorms dumped more than 4 inches of rain in localized areas — a reminder of the intensity these summer storms can reach, even in the absence of a widespread rainy pattern.
Michigan’s May cloudiness is gone — true summer has arrived
There are no indications that cloudy, damp patterns like those observed in May will return any time soon. As we approach July, classic Michigan summer weather — warm, sunny, and occasionally stormy — appears to be firmly in place.
Expect a true summer feel for the next few months in Michigan, with high temperatures running above normal and storm chances appearing in localized bursts.
