Detroit gets one more warm day today before the weather turns noticeably cooler and more unsettled. Mostly cloudy skies and temperatures around 72 degrees will give way to a high near 82, while northwest winds gust up to 23 mph and a stray shower remains possible later in the day.

Warm Sunday Gives Way To A Cooler Monday

Most of today should stay mostly sunny after the cloudy start, with rain chances around 10%. A few showers are possible during the afternoon and early evening, but the National Weather Service Detroit/Pontiac forecast calls for limited rainfall before skies clear and temperatures fall to around 54 overnight.

Tomorrow brings a quick taste of fall, with sunny skies and a high near 71. Tomorrow night should be partly cloudy with a low around 59, while patchy fog may develop around nearby lakes and rivers during the coolest overnight hours.

Tuesday Brings Back Heat And Storm Chances

Tuesday rebounds to around 84 degrees under partly sunny skies, but the warmth comes with a 40% chance of showers from morning into late afternoon. Thunderstorm chances rise sharply Tuesday night, when the forecast calls for an 82% precipitation chance and a low around 65.

The unsettled pattern continues through the rest of the week. Wednesday brings a 50% chance of showers and thunderstorms with a high near 75; Thursday has the strongest storm signal at 60% with a high near 78, and shower chances linger Friday and Saturday.

Waterfront Plans Need A Wind Check

Boaters should check conditions before heading out, as small craft advisories are scheduled to begin this afternoon for portions of Lake Huron, Lake St. Clair, and Lake Erie. The latest outlook is a substantive update from Hoodline's forecast last Friday, with stronger winds today and a more clearly defined stormy stretch arriving Tuesday night.
