DETROIT – An Air Quality Alert will be in effect for Macomb, Monroe, Oakland, St. Clair, Washtenaw and Wayne counties Sunday.

Welcome to Saturday night, Motown.

Tonight will be warm. Tomorrow will be hot. The, at times, stagnant air will be fertile ground for growing air pollution levels. It gradually becomes more humid Monday and much of next week. This will give rise to the possibility of on and off showers and thunderstorms along with more oppressive conditions.

Saturday night will be clear and warm. Overnight lows will be in the middle and upper 60s. Saturn and Jupiter will be visible in the southern and southeastern sky between 4:00 a.m. and 5:30 a.m. ET, Sunday.

Sunrise is at 5:58 a.m.

Sunday will be hot, mostly sunny and more steamy. Afternoon temperatures will be in the low 90s with heat indices in the middle and upper 90s. The record high is 94 degrees, set in 1988.

Monday provides the opportunity for Detroit to have a heat wave. If Saturday and Sunday have 90-degree readings, then we’ll have a heat wave with Monday potentially becoming the third consecutive day with a 90 degree high temperature.

Tuesday will be partly sunny and hot and humid. Daytime temperatures reach 90 degrees.

Wednesday and Thursday will have increased instability. It will be sweltering, again. Highs will be near or above 90 degrees. Also, there is a chance of showers and thunderstorms.
