The weather on Halloween won‘t be perfect, but it also won’t be a nightmare.
A storm system is going to move through Michigan from Wednesday night through Halloween. Right now, it looks like the brunt of the wet weather with this storm system will occur during the first half of Thursday, possibly leaving the trick-or-treat time mostly dry for Lower Michigan.
It seems that around Halloween is a very common time for our first large fall storm system. In fact, many years we see our first wet snowflakes in Lower Michigan around Halloween.
Here‘s the rainfall forecast in six-hour increments. This definitely shows rain crossing Michigan. Some good news is the precipitation won’t be snow.
For the southern half of Lower Michigan, Halloween should have an off-and-on showery pattern mostly in the morning and winding down in the afternoon. Northern Michigan will have quite a steady rain in the morning, and also tapering off in the afternoon. The Upper Peninsula will be fairly wet into Halloween evening.
Here‘s a good way to get a feel for rain amounts during trick-or-treating. The forecast below is the total rainfall forecast for 2 p.m. to 8 p.m. Halloween. Ann Arbor, Detroit, Flint and the Thumb will have leftover showers producing one-tenth of an inch of rain. That‘s generally considered light rain and probably ending sometime mid-afternoon. Even the southeast corner of Michigan could wind up with dry weather during trick-or-treating. Notice a dry swath from southwest Lower, Grand Rapids, Kalamazoo and Muskegon through to the northeast corner of Lower Michigan. Northwest Lower could have a few light rain showers left in the mid-afternoon of Halloween. Overall it’s not going to be too wet during the late afternoon and evening.
Temperatures are going to be fairly warm compared to many Halloweens in the past. Temperatures should be well into the 60s across most of Lower Michigan at 2 p.m.
Cooler temperatures will develop after dark, but not cold by any stretch. Look for temperatures to be in the 50s during trick-or-treat over southern Michigan and in the 40s over northern Lower Michigan.
Probably the most uncomfortable part of Halloween evening weather will be a vigorous wind with gusts over 30 mph.
We will need to bundle up the kids just a touch, but you certainly won’t need to put them in a warm, furry costume. Watch for updates here on the exact timing of the end of the rain on Halloween.
