Grand Rapids is starting Halloween under gray skies, but the day itself should stay mild and mostly dry. Conditions were cloudy and around 45 degrees early Saturday, with temperatures expected to climb to about 61 by afternoon.

Halloween Looks Mostly Dry

Saturday’s forecast calls for mostly cloudy skies, light east-southeast winds around 6 mph and only a 6% chance of rain. That should give trick-or-treaters a comfortable window, with temperatures near 60 degrees in the late afternoon and early evening before falling through the 50s overnight.

A slight chance of rain showers arrives after 3 a.m. Sunday, so Halloween night does not appear headed for a washout. The National Weather Service Grand Rapids says spotty light rain is possible this weekend, but rainfall should remain limited.

Sunday Stays Mild Before The Pattern Turns Wetter

Sunday could begin with a few showers between 7 and 9 a.m., followed by partly sunny skies and a high near 67 degrees. Sunday night should remain mostly cloudy with a low around 50.

Monday keeps the mild temperatures going, reaching about 65 degrees, but rain chances rise after 1 p.m. Showers remain possible Monday night as temperatures stay unusually soft for early November, with a low near 56.

Rain Chances Rise Around Midweek

Precipitation chances rise considerably around midweek, though forecast certainty decreases starting Wednesday. Chances are 20% to 30% for the latter part of the week.

The weather service says quick rainfall could create nuisance flooding, especially where autumn leaves clog storm drains. Severe weather is not expected, and no watches or warnings are currently posted for the Grand Rapids area.
