GRAND RAPIDS, Mich. (WOOD) — The atmosphere will be capable of producing severe thunderstorms over West Michigan on Wednesday, especially in the evening.

Almost everyone will see heavy rain on Wednesday, especially south of Grand Rapids. Most thunderstorms will be subsevere but a few could produce damage. Environmental parameters show that severe winds or hail of 1 inch in size are the biggest threats with Wednesday’s storms.

The chance for tornadoes is currently low.


Wednesday will be a warm day with highs in the 60s and potentially approaching 70. It will likely feel humid with dew points climbing to near 60 degrees. We will be in the warm sector of a storm system passing through, which puts us in ideal conditions for storms to form.

Severe weather is most likely to come from the Ohio Valley south through the Mississippi River Valley.

Currently, West Michigan is under a “marginal” risk for severe weather, which is a one out of five on the severe weather risk scale. This means a few severe storms are possible, but not guaranteed or widespread.

Showers and thunderstorms will move through early Wednesday afternoon, but that round looks sub-severe.

As the cold front approaches from the west, we are expecting a second stronger line of storms to develop later Wednesday afternoon and evening.

Gusty winds overnight will likely bring in some wind gusts of 40-50mph.

Storms will clear out shortly after midnight with a sharp drop in temperatures and windy conditions building in for Thursday. A Wind Advisory will be in effect from 10 AM – 8 PM Thursday. Winds could gust as high as 55 mph through that time period.

Cold air dominates the extended forecast with several chances for snow continuing to pop up through late April.
