DETROIT – Welcome to Saturday, Motown.

This is the final full weekend of summer 2021.

It will be warmer than average. There is a slight chance of a few raindrops at the beginning. Then the rest of the time will be dry and pleasant. Higher than average temps are with us afterward until the start of Autumn 2021.

Saturday morning will be overcast to mostly cloudy. Some clouds will be low and thick producing spotty showers at dawn and through breakfast. These few raindrops are ahead of a cold front that pushes through the region during the day. Any rain showers move to the east and south before the morning is done. It will be drier with the clouds breaking apart by lunchtime.

Sunrise is at 7:17 a.m.

Saturday afternoon will be warmer and brighter. By the end of noon the Michigan football game against Northern Illinois University, the mercury climbs to the middle and upper 70s under sunnier skies.
