&&
.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
AN INFLECTION POINT ON IR SATELLITE IMAGERY TO OUR SOUTH IS
CURRENTLY SHOWING ITS HAND VIA COOLING CLOUD TOPS OVER CENTRAL
WEST VIRGINIA. THIS SEEMS TO BE EVIDENCE OF YET ANOTHER WAVE WITH
AN ELONGATED SLUG OF MOISTURE THAT IS FEEDING UP THE FRONT DRAPED
THROUGH OUR FORECAST AREA THIS EVENING. THIS WILL LIKELY BRING THE
LAST ROUND OF ENHANCED RAINFALL NORTHWARD FROM WEST VIRGINIA INTO
PENNSYLVANIA OVERNIGHT. GIVEN THE TRENDS ON SATELLITE...IT WILL
LIKELY BE A FEW MORE HOURS BEFORE THE FRONT MAKES ANY ADDITIONAL
EASTWARD PROGRESS. OWING TO THIS...POPS AND QPF WERE RAMPED UP
SIGNIFICANTLY FOR THE REMAINDER OF THE EVENING IN WESTERN
PENNSYLVANIA. THE FLASH FLOOD WATCH WILL REMAIN IN EFFECT...AS
LOCATIONS IN THE LATEST SLUG OF MOISTURE ARE EXPERIENCING
WIDESPREAD REPORTS OF HEAVY RAINFALL.
ONCE THE WAVE TRACKING UP THE FRONT MOVES TO THE NORTHEAST
OVERNIGHT...IT WOULD SEEM THE RETURN FLOW AROUND IT SHOULD FINALLY
GIVE THE FRONT AN EASTWARD KICK. WITH WILL START TO BRING LOWER
DEWPOINTS AND A MUCH LESS COHERENT SHOWER FIELD INTO THE CWA
PROGRESSIVELY FROM WEST TO EAST. WITH DRIER AIR FEEDING
PARTICULARLY INTO THE WESTERN CWA TONIGHT...AND CURRENT WATER
VAPOR IMAGERY INDICATING A DEARTH OF MID AND UPPER LEVEL MOISTURE
IN THE DRY SLOT BEHIND THE FRONT...IT WOULD SEEM THE ONGOING COLD
ADVECTION STRATOCUMULUS OVER INDIANA/WESTERN OHIO SHOULD FADE
AFTER SUNSET. AS A RESULT...SOME SCATTERING OUT OF THE SKIES SEEMS
LIKELY BY THE LATER OVERNIGHT HOURS/MORNING...PARTICULARLY IN
OHIO. SKIES HAVE BEEN EDGED DOWN TEMPORARILY UNTIL DIURNAL
INSTABILITY AND THE INCOMING UPPER VORTEX SHOULD ALLOW FOR
ADDITIONAL CLOUDS TO REDEVELOP BY AFTERNOON FRIDAY. FRIES
&&
.SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/...

.AVIATION /03Z FRIDAY THROUGH TUESDAY/...
DEEPER MOISTURE WILL BE SLOW TO ERODE BEHIND THE FRONT W TO E
TONIGHT ALLOWING ANOTHER MASS OF RAIN TO MOVE NORTH FROM WV WITH
THE NEXT WAVE. WILL CARRY MVFR CONDITIONS WITH TEMPOS TO IFR AS
THE RAIN WORKS S TO N OVER THE ERN HALF OF OUR FORECAST AREA
THROUGH ABOUT 06Z.
MODEL GUIDANCE IS MIXED AS TO HOW QUICKLY DRIER AIR WILL WORK IN
