FIRE WEATHER PLANNING FORECAST
NATIONAL WEATHER SERVICE PITTSBURGH PA
1229 PM EDT THU APR 9 2026
DISCUSSION
DAYTIME MINIMUM HUMIDITIES ARE LIKELY TO FALL INTO THE 30S, AND
POTENTIALLY TOUCH INTO THE UPPER 20S, THIS AFTERNOON AS WELL AS
FRIDAY AFTERNOON GIVEN DEEP MIXING OF DRY AIR TO THE SURFACE IN
CONJUNCTION WITH RISING TEMPERATURE (AND LIMITED MOISTURE
ADVECTION). THE PROBABILITY OF HUMIDITY AND WIND RED FLAG CRITERIA
REMAINS LOW DUE TO LACK OF CONSISTENTLY GUSTY WIND, BUT
MOMENTARY GUSTS BETWEEN 15 TO 25 MPH EACH AFTERNOON COULD OCCUR.
THE ONLY NOTABLE REPRIEVE OF ELEVATED FIRE WEATHER CONCERNS IS A
SAGGING FRONT THAT RAISES DEW POINTS AND OFFERS LOW CHANCE SHOWERS
TONIGHT ALONG THE I-80 CORRIDOR BEFORE PUSHING SOUTHEAST FRIDAY
AFTERNOON/EVENING WITH MORE WIDESPREAD RAIN CHANCES.
LOOK FOR DRY AND SEASONABLE WARM TEMPERATURE TO RETURN SUNDAY INTO
NEXT WEEK THAT CREATE ADDITIONAL ELEVATED WILDFIRE RISK CONCERNS.
