Southeast Michigan is sweltering under a dangerous heat wave that is expected to intensify in the coming days, with temperatures threatening to shatter a century-old record and heat index values soaring as high as 105 degrees.
An Extreme Heat Warning remains in effect for Genesee, Oakland, Macomb, and Wayne counties until 8 p.m. Tuesday, while surrounding counties, including Sanilac, Lapeer, St. Clair, Livingston, Washtenaw, Lenawee, and Monroe, remain under a Heat Advisory.
Heat Building Across the Region
Communities under the Extreme Heat Warning are likely to experience the highest heat indices, and the scorching daytime temperatures will be compounded by warm, muggy nights. Overnight lows in urban areas are expected to remain in the mid-70s, but humidity will make it feel closer to 80 degrees, providing little relief.
Record-Breaking Heat Possible Monday
Monday marks the third consecutive day of temperatures above 90 degrees in Metro Detroit. Forecasters say Monday’s highs will climb into the upper-90s to near 100 degrees, with heat index values reaching up to 105 degrees. This would break the longstanding June 23 record of 95 degrees, set in 1923.
Even after sunset, conditions will remain steamy. Those attending the Ford Fireworks Monday night should expect temperatures in the mid-80s, with a “feels-like” temperature near 90 degrees around 10 p.m.
Storm Threat Returns Tuesday
The scorching heat continues Tuesday with highs back in the mid-90s and heat indices near 100 degrees. However, showers and thunderstorms are expected to develop along a cold front in the afternoon, bringing some relief but also the potential for severe weather. The Storm Prediction Center has placed the region under a marginal risk (level 1 of 5) for severe storms.
Slight Cooling Midweek, But Heat Lingers
By Wednesday and through next weekend, temperatures are forecast to drop slightly but will still hover in the upper-80s to lower-90s, with overnight lows around 70 degrees.
Health and Safety Reminders
Officials are urging residents to take the heat seriously, especially vulnerable groups like children, seniors, and individuals with heart or respiratory conditions. Pet owners should exercise caution, as pavement temperatures can soar to 150 degrees, posing a risk of burns or worse to pets.
Key Safety Tips:
- Limit outdoor activities
- Stay hydrated
- Never leave children or pets in vehicles
- Check on elderly neighbors and those without air conditioning
- Keep pets off hot pavement
This heat wave is expected to strain both residents and infrastructure. Authorities advise everyone to remain vigilant and take proper precautions until temperatures ease later this week.
