4WARN WEATHER – The average date for the first freeze for Metro Detroit is Oct. 25, and some of us could experience freezing temperatures over the weekend.

In addition to cool temperatures and rain, the wind remains an issue.

A small craft advisory is in effect for a stretch of the nearshore waters of Lake Huron in Southeast Michigan from 8 p.m. this evening until 8 p.m. Sunday. The advisory will be in effect for Outer Saginaw Bay to Port Sanilac.

Northwesterly winds will be up to 15 kt on Friday night. Saturday, winds will be up to 15 knots with gusts up to 20 kt. Sunday, winds will be out of the northwest and north-northwest at 15 to 20 kt with gusts up to 30 mph. Waves will be capable of reaching a maximum height of 11 feet.

Cooler air will push into the area. We will have sporadic showers on Saturday before rain chances fall during the evening. It will also be cool and windy. Highs will be in the lower to mid 50s in Metro Detroit. Expect similar conditions in East Lansing for the Michigan vs. Michigan State game, but the chance of showers will be low during game time.

Then, we will have a brief warm up with temperatures in the lower to mid 60s for the rest of the workweek. Cooler air will return for the weekend.
