Fire Weather Planning Forecast for Southeast Michigan
National Weather Service Detroit/Pontiac MI
300 PM EDT Fri Apr 20 2018

.DISCUSSION...Mostly quiet conditions through the weekend as a high
pressure moves out of the Plains and into the Great Lakes through
the weekend. Look for a gradual warm up in high temperatures with
50s this afternoon through Sunday and reaching into the lower 60s
early next week. Dry conditions arrive with the calm weather
resulting in minimum RH values dropping into the upper 20s and 30s
this afternoon. Good recovery overnight tonight under calm winds
with minimum relative humidity values on Saturday back down in the
low to upper 30 percent range.
