Fire Weather Planning Forecast for Southeast Michigan
National Weather Service Detroit/Pontiac MI
303 AM EDT Thu Jul 27 2017

.DISCUSSION...Scattered showers and thunderstorms will be possible
today as a cold front settles south through the area. Minimum RH
values will be rather high, 50-65 percent, as moisture pools along
this frontal boundary. While a few showers may linger into Friday,
drier air will filter into the area as high pressure builds south.
Minimum RH values will fall to 45 to 55 percent in most locations.
Temperatures will also be much cooler, in the 70s, as northeast
winds increase in the wake of the cold front.
