National Weather Service Grand Rapids MI
452 AM EDT Wed Aug 16 2017

.DISCUSSION...
High pressure will provide pleasant weather today. Low pressure
tracking northeast through Wisconsin on Thursday will send very
humid air into the region that will help trigger numerous showers
and thunderstorms. Some of the storms could be strong and produce
torrential rainfall. Cooler and breezy weather will follow on
Friday then temperatures will moderate back to near to above normal
over the weekend into early next week.
