National Weather Service Grand Rapids MI
345 AM EDT Tue Jul 15 2025

...Hot and increasingly humid today and Wednesday...

.DISCUSSION...
High pressure moving out of the area will allow for southerly
winds to redevelop, and bring warmer and more humid conditions
back over the area through Wednesday. A couple of waves of
low pressure will bring a few showers and storms to the area
late tonight through early Thursday. Cooler air will come in
Thursday behind a cold front that passes through.
