WEST MICHIGAN — The forecast from Weather Ready Meteorologist Gracyn Freund: Clouds will continue building in through the rest of today ahead of our next system. Any late-day outdoor plans should be safe for much of the area, but rain chances will increase by late this evening. Rain will be steady overnight, and then we'll be waking up to widespread rain and possibly a few embedded thunderstorms on Saturday. Our computer models are shifting the heaviest rain a bit south which would mean that the heaviest rain will fall towards the I-94 corridor. Rain becomes lighter and spotty into the early afternoon, and we may get lucky and see a dry window between the afternoon and evening. Another round of rain will move in Saturday night, continuing into early Sunday. The later half of Sunday is trending dry. Rain totals could be 2" or higher in spots, leading to some ponding on the roads and street flooding. As a result, A Flood Watch has been posted for many counties south of I-96 through 8AM Sunday. It will be much cooler this weekend with highs only in the 60s. More rain chances are in the forecast early next week, along with mostly cloudy skies most days. Temperatures will stay cool ranging from the lower to upper 60s... just in time for the start of Fall on Tuesday!

TONIGHT: Rain and a few thunderstorms moving in. Lows in the mid 50s. Wind E at 10-15 mph.

SATURDAY: Cloudy with widespread rain and a few thunderstorms, especially early. Highs in the low/mid 60s. Breezy, Wind E/SE at 10-15 mph.

SUNDAY: A.M. rain, otherwise mostly to partly cloudy. Highs in the mid/upper 60s.

MONDAY: Mostly cloudy with chance showers. Highs in the lower 60s.

TUESDAY: Mostly cloudy with chance of a stray shower. Highs in the low 60s. First day of Fall!

WEDNESDAY: Mostly cloudy with chance of a stray shower. Highs in the mid 60s.

THURSDAY: Mostly cloudy with highs in the upper 60s.

FRIDAY: Partly cloudy with highs around 70.
