Fire Weather Planning Forecast for Southwest Lower Michigan
National Weather Service Grand Rapids MI
421 AM EDT Mon Aug 4 2025

...Mainly dry and increasingly warmer through the week...

.DISCUSSION...
High pressure that has been centered over the area over the last
couple of days will slowly move away from the area through
Wednesday. It should continue to provide enough control to keep
all areas dry through Tuesday. There will be a slight chance of
an afternoon shower or storm for inland areas on Wednesday, but
most areas will stay dry. Warmer temperatures will continue
each day, with more humid conditions moving in later this week.
