FIRE WEATHER PLANNING FORECAST FOR CENTRAL PENNSYLVANIA
NATIONAL WEATHER SERVICE STATE COLLEGE, PA
144 AM EDT MON MAY 18 2026
DISCUSSION
HEAT WILL BE ON THE INCREASE TODAY AND TUESDAY, BUT ONLY MODERATE
INCREASES IN SURFACE DEWPOINTS AND DEEP VERTICAL MIXING UP TO 6 OR
7 THOUSAND FEET BOTH AFTERNOONS WILL LEAD TO MIN RH VALUES MAINLY
IN THE LOW TO MID 30S (%).
FAIRLY WARM TEMPERATURES IN THE MID LEVELS OF THE ATMOSPHERE WILL
PUT A LID ON MOST OF THE CONVECTION (SHOWERS AND THUNDERSTORMS)
TODAY AND TUESDAY. HOWEVER, SELECT AREAS OF OROGRAPHIC FORCING
AND THE PASSAGE OF A SUBTLE UPPER LEVEL DISTURBANCE WILL HELP TO
FORM A FEW MID AFTERNOON TO EARLY EVENING SHOWERS AND
THUNDERSTORMS ACROSS THE LAUREL HIGHLANDS AND SOUTH- CENTRAL
MOUNTAINS. A FEW OF THE THUNDERSTORMS LATER THIS AFTERNOON COULD
PRODUCE BRIEF WIND GUSTS OF UP TO 45 MPH.
RAINFALL ACCUMULATIONS SHOULD AVERAGE BELOW 0.10" (AND MOST
LOCATIONS LIKELY STAY DRY).
A STRONG COLD FRONT WILL BRING SHOWERS AND SCATTERED THUNDERSTORMS
ON WEDNESDAY, SOME OF WHICH COULD BE SEVERE IN THE AFTERNOON AND
EARLY EVENING. COOLER, MORE SEASONABLE CONDITIONS WILL FOLLOW FOR
THE END OF THE WEEK AND INTO MEMORIAL DAY WEEKEND.
