An Extreme Heat Watch has been issued for all of Southeast Michigan from noon to 8 p.m. Tuesday as dangerously hot and humid conditions are expected to develop across the region. An Extreme Heat Watch is issued when conditions are favorable for life-threatening heat. Watches are often upgraded to an Extreme Heat Warning or Heat Advisory within 24-hours of the heat-related event, so additional heat alerts are likely before Tuesday. The 4Warn Weather team has issued a 4Warn Weather Alert for Tuesday due to the dangerous heat.
Mostly sunny (High UV Index) with highs in the low 90s this afternoon. Temperatures will climb into the 90s today through Wednesday, with the most intense heat expected on Tuesday. Afternoon highs are forecast to reach the upper 90s, while oppressive humidity will push heat index values to near or above 100 degrees. The combination of heat and humidity will create dangerous conditions for anyone spending extended time outdoors, so limit strenuous outdoor activities during the hottest part of the day, stay well hydrated, take frequent breaks in air-conditioned locations, and check on elderly neighbors, young children, and anyone without adequate cooling.
The intense heat begins to ease later in the week, although warm and humid conditions will persist with highs around 90 on Thursday and Friday. Rain chances return by the end of the week, with the next opportunity for showers and thunderstorms arriving late Friday night into Saturday morning.
