Hot, humid weather arrives with storm chances in Metro Detroit

A splendid summer Saturday will be followed by a sauna-like Sunday in Metro Detroit.

Daytime and overnight temperatures will increase. Saturday night, lows will be in the lower to mid 60s. The warmer locations will be near Detroit, Warren, Dearborn and Downriver. Lows will be around 60 degrees in the Thumb. Skies will be partly cloudy, and southwesterly winds will be 5 mph and lower.

Sunday

Sunday morning will bring the chance of a few sprinkles in the morning. Then, an isolated shower or thunderstorm could pop up during the afternoon and evening. The Storm Prediction Center has placed areas south of M-59 in Southeast Michigan in the marginal (level one of five) risk category, because there is a very low chance that an isolated thunderstorm could produce gusty winds. Sunday’s low risk should not warrant a change of outdoor plans, unless threatening weather approaches. Most areas will not see any rain. Plan on partly cloudy skies, but check the 4Warn Weather App for Exact Track 4D Radar and any updates.

The bigger issue for most people will be the heat. Sunday afternoon’s temperatures will reach the upper 80s in Metro Detroit and the mid 80s in the Thumb. Winds will be out of the south and southwest around 5 mph.

Sunday night, under partly cloudy skies, lows will be in the upper 60s.

Monday

The heat and humidity will turn up a notch on Monday. Drinking water and other healthy beverages will be key. Highs will be around 90 degrees, while the heat index will reach the lower 90s. It will be partly cloudy during the day and night. Lows will only be around 70 degrees.

Tuesday

The conditions will be favorable for Tuesday to get even hotter. A warmer, more humid air mass will push into Southeast Michigan, which will be followed closely by a cold front. There is a chance of showers and thunderstorms, including the possibility for a couple of them to become strong to severe. Highs will be in the lower 90s with heat indices in the mid to upper 90s.

Midweek through Weekend

A stray shower will be possible on Wednesday, but the chance is very low. There will be a slight chance of rain on Thursday and a better chance on Friday. The daytime highs will cool to near normal by next weekend.
