Fire Weather Planning Forecast for Southwest Lower Michigan
National Weather Service Grand Rapids MI
324 PM EDT Sun Apr 23 2017

...Another Dry Day on Monday and Tuesday then Trending Wet...

.DISCUSSION...
A couple of days without rain combined with plenty of sunshine and a
dry air mass has allow RH`s to drop down below 30% this afternoon at
many locations. Fire danger is not too bad with winds staying below
10 knots at most locations. Conditions are a little breezy toward
Mt. Pleasant, Big Rapids, and Alma.

We expect close to a repeat on Monday with regards to RH`s as we
should mix down dry air. Winds should remain on the lighter side and
be more from the East/Southeast. We do expect better moisture will
move in over the area for Tuesday with southerly winds drawing
moisture northward. Rain chances will increase mid-late week.
