The “extreme heat” is expected to intensify and shatter a century-old record in Metro Detroit.
An Extreme Heat Warning is in effect for Genesee, Oakland, Macomb and Wayne counties until 8 p.m. Tuesday.
A Heat Advisory covers all other counties in Southeast Michigan, including Sanilac, Lapeer, St. Clair, Livingston, Washtenaw, Lenawee and Monroe counties.
Heat index values up to 105 degrees will be possible in Southeast Michigan during the warning and advisory period. Communities under the Extreme Heat Warning are more likely to see the higher heat indices. The nighttime temperatures will also be higher in urban areas than rural communities.
Heat stress is being exacerbated by very warm and muggy nights.
Sunday night is expected to be mostly clear and warm. Lows will be in the mid-70s, but it will feel like it is near 80 degrees. Southwesterly winds will be at 5 to 10 mph.
Monday
Monday, which will mark the third day of the heat wave and temperatures above 90 degrees, is expected to break the record high for June 23. The thermometer hit 95 degrees in Metro Detroit in 1923. Monday’s highs will be in the upper-90s to near 100 degrees. Heat indices, or feel-like temperatures, will be up to 105 degrees.
The Ford Fireworks are set to light up the Monday night sky. Do not plan on the temperatures to cool down much. The forecast calls for mid-80s for the start of the fireworks around 10 p.m. It will feel like 90 degrees.
Monday’s night’s lows will be in the mid- to upper-70s, under mostly clear skies.
Tuesday
The chance of showers and thunderstorms will begin Tuesday and last through the week.
Under mostly sunny to partly cloudy skies, Tuesday’s highs will again return to the mid-90s. The heat index will be around 100 degrees. Amid the heat and humidity, showers and thunderstorms will begin to develop in the afternoon along a cold front.
A few of the storms could become strong to severe. The Storm Prediction Center has placed Southeast Michigan under the marginal, or level 1 of 5, risk.
Tuesday night’s temperatures will cool to around 70 degrees.
Wednesday
Wednesday through next weekend, highs will be in the upper-80s to lower-90 degrees. Nighttime temperatures will cool to around 70 degrees.
Health and Safety Precautions for People and Pets
It is essential to take precautions, especially for children, seniors, and people with heart or respiratory conditions.
Do not forget about pets. If it is too hot for your hand on the pavement, it is too hot for your pets’ paws. With concrete and asphalt temperatures reaching up to 150 degrees, even a walk can put your four-legged family members at risk for burns or worse.
Limit outdoor activities, stay hydrated, and keep an eye on those who might be most vulnerable. Checking on neighbors, loved ones, and pets could make a crucial difference while Southeast Michigan navigates this heat wave
