Grand Rapids will remain mostly cloudy into Wednesday morning. Tuesday's afternoon high should reach about 64 degrees, setting up a noticeably warmer Wednesday before rain returns later in the week.

Tuesday will stay mostly cloudy with east-southeast winds around 8 mph and occasional gusts near 18 mph. There are no active watches, warnings or advisories for the area, according to the National Weather Service in Grand Rapids.

Wednesday Is The Week’s Best Weather Window

Wednesday looks like the standout day, with mostly cloudy skies lingering into the morning and a high near 72 degrees. Southwest flow will build into Wednesday, making it the best bet for outdoor plans before the forecast turns wetter.

Light Rain Likely Thursday, With Isolated Thunder Possible

A slight chance of showers begins late Wednesday night, then rain becomes much more likely Thursday. Rain chances are highest Thursday morning and afternoon, with showers likely mainly after 2 p.m. An isolated rumble of thunder cannot be ruled out, with a 60% chance of precipitation and a high around 70 degrees.

Light northerly winds move in behind the front Thursday evening.

Friday Looks Calmer Before A Showery Weekend

Friday brings a brief reset with mostly sunny skies and a high near 66 degrees. Rain chances return Saturday and continue into Sunday, when mostly cloudy skies and a high near 67 degrees could complicate Halloween weekend plans and other outdoor activities.

Showers remain possible Monday as temperatures stay mild, with a forecast high near 67 degrees. For now, Wednesday is the clear favorite for sunshine, while Thursday carries the week’s biggest rain and thunderstorm concerns.
