DETROIT – The heat and humidity are building across Southeast Michigan this Tuesday, setting the stage for powerful storms on Wednesday, especially in the Metro Detroit area. Today remains mostly quiet, with partly cloudy skies and temperatures climbing into the mid-80s (around 29°C). While a few isolated showers or non-severe thunderstorms may pop up, most of the region will stay dry.
Strong storms expected Wednesday in Southeast Michigan
A 4Warn Weather Alert has been issued for Wednesday afternoon and evening, as a potent storm system moves into the region. Southeast Michigan is currently under a slight to enhanced risk for severe weather, and the situation is being closely monitored.
The day may begin with morning and midday thunderstorms tied to a warm front lifting northward. However, the greatest threat for severe weather will emerge late Wednesday afternoon into the evening, as a surface low-pressure system drags a cold front across central Michigan.
All severe hazards are possible:
⚠️ Damaging wind gusts topping 70 mph (over 113 km/h)
⚠️ Possible tornadoes
⚠️ Large hailstones, greater than 1 inch (2.5 cm) in diameter
⚠️ Heavy rainfall, potentially triggering localized flooding
Residents across Metro Detroit, Ann Arbor, Flint, and Pontiac should stay weather-aware through Wednesday evening, especially during the commute home.
Looking ahead: Juneteenth and the first day of summer
Juneteenth on Thursday starts off with a few pre-dawn showers, but the skies will turn partly cloudy with seasonal highs near 80°F (27°C) — a comfortable break before the heat intensifies again.
On Friday, the summer solstice arrives, and so does the summer heat. Expect mid-80s (around 29°C), then near 90°F (32°C) on Saturday, and well into the 90s (above 35°C) from Sunday into the early part of next week.
Ford Fireworks Monday: Prepare for scorching sunshine
The Ford Fireworks show is scheduled for Monday night in Downtown Detroit, and the current forecast calls for sunny skies and extreme heat. Temperatures will soar to the mid-90s (around 35°C), so bring plenty of cold water, and an umbrella or a pop-up tent — not for rain, but for shade from the blazing sun.
The humidity will also make it feel even hotter, so those heading downtown should plan for a sweltering evening.
