Fire Weather Planning Forecast for Southeast Michigan
National Weather Service Detroit/Pontiac MI
402 AM EDT Fri Jun 23 2017

.DISCUSSION...Most locations will see wetting rainfall early today as
a cold front sweeps southeast through the area. Dry weather is
expected late today and tonight. Cooler conditions will develop
behind the front, and be reinforced by several more shots of cooler
air over the weekend. This will bring a cooling trend to
temperatures, with highs Sunday and Monday only reaching into the
upper 60s to low 70s. A few showers and thunderstorms are possible
on Saturday, with a slightly better chance expected on Sunday.
