FIRE WEATHER PLANNING FORECAST
NATIONAL WEATHER SERVICE PITTSBURGH PA
104 PM EDT THU SEP 11 2025
DISCUSSION
DRY WEATHER IS EXPECTED TO PREVAIL FOR MOST OVER THE NEXT 7 TO 10
DAYS, WITH AN EVEN SMALLER CHANCE OF ANY WETTING RAIN. DAYTIME
MINIMUM RELATIVE HUMIDITIES ARE EXPECTED TO DROP INTO THE 30S TO
UPPER 20 EACH DAY, TENDING TOWARD THE LOWER END OF THE RANGE WHEN
SKIES ARE CLEARER. ON THE OTHER SIDE, NO GUSTY WINDS ARE EXPECTED
THROUGH THE WHOLE PERIOD UNDER HIGH PRESSURE. WHILE CALM WINDS
WILL PRECLUDE FIRE SPREAD, FUEL DRYING IN 100-HR TO 1000-HR
FUELS IS EXPECTED. THIS WILL CONTINUE TO INCREASE FIRE IGNITION
RISKS AND WILDLAND FIRE RISKS INTO MID-TO-LATE SEPTEMBER WITHOUT
MITIGATION FROM RAINS.
