Metro Detroit weather: Scattered storms with high heat, humidity through Monday evening

Temps in rain-cooled 70s and 80s this evening

DETROIT – Welcome to Monday afternoon, Motown.

Monday’s high heat and humidity provides the perfect recipe for showers and thunderstorms in the afternoon and evening. It remains warm and muggy before midnight, with a break in stormy activity until Tuesday morning. Hot and muggy weather with storm chances will be with us until the end of the workweek.

Monday afternoon is hotter than average, and humid. Scattered showers and thunderstorms will move from south to north, with heavy downpours, lightning and gusty winds.

When it’s not raining, highs will be in the upper 80s. The humidity will make it feel like it’s in the 90s. Remember to stay cool, hydrated and healthy and keep kids and pets away from empty vehicles.

Showers and storms become more widely scattered Monday evening. This will leave mostly cloudy skies through nightfall. Temperatures will go from the 80s to the mid- and upper 70s.

Sunset is at 8:42 p.m.

Skies will be mostly cloudy Monday night with enough moisture in the atmosphere to keep it unstable. A disturbance to our west will approach the region with a line of showers and thunderstorms. Before midnight, it remains pretty calm. After midnight, especially early morning hours of Tuesday, those storms arrive. Between 2:00 a.m. and 3:00 a.m. they enter our West Zone (Livingston and Washtenaw Counties) and Lenawee County. After 3:00 a.m., the move over the rest of Southeast Michigan.

Heavy downpours, frequent lightning and damaging wind and hail may occur before many wake up. Make sure weather radios have fresh batteries in case any alerts are issued.

Sunrise is at 6:35 a.m.

Tuesday will be stormy in the morning, and the “muggies” remain with us. It will be hot and humid in the afternoon, with highs near 90 degrees and heat indices in the mid-90s. Summer campers and athletes with outdoor practices will need to take frequent water breaks and stay in or near air conditioned areas.

We continue to sizzle Wednesday and Thursday, with on-and-off showers and storms. Highs each day will be in the mid- and upper 80s, with feels-like temps in the 90s.
