DETROIT – Wednesday afternoon's highs near 80 degrees might be our warmest finish for the next 10 days.
On Wednesday night, we'll be fog free. A cold front will cross through Metro Detroit overnight and bring a small chance of a shower or thunderstorm. Better chances will be in our North Zone. Otherwise, expect partly cloudy skies and lows in the low 60s in most spots.
Strong onshore winds have prompted a Lakeshore Flood Advisory for Sanilac and St. Clair counties from midnight until 4 a.m. Friday. The winds could lead to shoreline flooding, erosion and even damage to boats and docks.
Cloud cover will start us out on Thursday, with sunshine emerging in the afternoon. Even with bright skies, the cooler air behind Wednesday night's front will keep highs in the mid-60s to low 70s. Check our 4ZONE page for a breakdown of those numbers.
Thursday night will be our chilliest point, with 40-degree temperatures in almost every location by daybreak on Friday.
The start of our holiday weekend will be unseasonably cool. On Friday, highs will struggle to hit 70 degrees in our Metro and South Zones, but many areas will remain in the 60s. That will be under partly cloudy skies.
What's left of Harvey will stay south of us Saturday. We might get some fairly thick clouds, however, especially in our South Zone. Highs will be slightly warmer, in the low to mid-70s.
Sunday and Labor Day Monday will be close to normal for this time of year, with highs near 80 degrees. That stretch will be dry until late Monday. It looks like thunderstorms should hold off for most of us until Monday evening.
