High in the 70s

By Andrew Humphrey, CBM - Meteorologist And Station Scientist

DETROIT - A bit cooler than average with some wet weather for Motown's GM River Days weekend. Fortunately, no wash-out Saturday and Sunday, and sunshine and fair skies emerge on the day and night of the Ford Fireworks.

Please join me on Twitter (@AndrewHumphrey) for regular weather updates.

Saturday morning will be cool and cloudy. Temperatures start in the 60s and some scattered light rain will keep some streets wet. Farmers and gardeners will be happy about some of Mother Nature's liquid sunshine for their crops and plants. Lawns will like it, too. Families just need to be careful driving on wet roads.

Sunrise is at 5:58 a.m.

Saturday afternoon will have scattered showers and thunderstorms. Highs in the middle and upper 70s with plenty of cloud-cover. Periods of dryness will exists, so people can still have a great time at GM River Days in downtown Detroit along the Detroit River.
