Fire Weather Planning Forecast for Southwest Lower Michigan
National Weather Service Grand Rapids MI
329 PM EDT Mon Mar 18 2024

.DISCUSSION...

Breezy northwest winds today turn to the southwest tomorrow with
gusts 20 to 30 mph. The lowest relative humidity values are expected
along and south of a Kalamazoo to Lansing line in the upper 30s to
low 40s. Mixing heights will be around 4000 feet with good smoke
dispersal due to the gusty winds and higher mixing heights.

There will be a couple chances for light snow tonight and tomorrow
night. Only light accumulations are expected at this time. Wednesday
and Thursday still have the lowest relative humidity values in the
30s to low 40s. We`ll have to watch the potential for values to drop
below 30 Thursday, but winds will be lighter.

We move more into a wet pattern Thursday night and into next week
with multiple chances for rain and snow.
