Area forecast discussion, Jun 16, 1:45 PM EDT, 7 hours 23 minutes before
CENTRAL PENNSYLVANIA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 145 PM EDT TUE JUN 16 1998 WORK ZONES WILL BE SENT TO PIT AND PHL VIA PHLADMCTP BY 245 PM. ...DISCUSSION... 15Z SFC ANAL SHOWS A WEAK DIFFUSE SFC PATTERN. THE PRIMARY COLD FRONT IS ARCED FROM NEAR ART TO JUST NE OF LGA AND IS FOCUSING +SHRA AND +TSRA OVER E NEW ENG. IN ITS WAKE DEWPTS ARE IN THE MID 60S WITH LOW 70S UP INTO THE MID ATL. THE AIR IS RATHER MOIST UP THROUGH 85H WITH VERY WEAK WINDS ALOFT. WE HAVE ALSO COOLED ABOUT A DEGREE AT 50H AND WILL COOL ANOTHER BY 0Z WED. SO AIR MASS BECOMING MORE UNSTABLE AS AFTN PROGRESSES. WIND PROFILES REMAIN UNFAVORABLE FOR WIDESPREAD SVR WX THRU THE AFTN BUT WITH LIGHT WINDS ALOFT THERE IS SOME POTENTIAL FOR BACK BUILDING. THIS COULD LEAD TO ENOUGH RAIN FOR SOME FLASH FLOODING BUT THE PICTURE IS SO DIFFUSE IT IS TOUGH TO MAKE A CALL AS TO WHERE TO PUT UP THE WATCH. MY INCLINATION IS TO PLACE IT ACROSS THE NORTH AND CENTRAL WHERE A WARM FRONT APPRS TO BE DEVELOPING ON THE SAT LOOP. BUT THE SHRA DEVELOPING ALONG THIS BOUNDARY APPRS TO BE MOVG RIGHT ALONG AND WE NEED TO CONCENTRATE OR SLOW SHRAS TO PRODUCE ENUF RAIN FOR FF. ANOTHER AREA FOR POTENTIAL FF WOULD BE SOUTHERN TIER COUNTIES WHERE VORT MAX IS EXPECTED TO CROSS. INFLOW AT LOW LEVELS IS QUITE STRONG WHEN COMPARED TO WINDS ALOFT AND THIS COULD SLOW THE NET MOVEMENT OF STORMS AND DUMP HEAVY RAIN. PWATS ARE HIGHER OVR S PA MD WV AND VA AND A SOUTH OR SW INFLOW AT LOWER LEVELS COULD PULL IN SOME GOOD JUICE FOR HEAVY RAIN PRODUCERS. I WOULD WAIT AND SEE IF CENTRAL AND NORTH BECOMES ACTIVE THIS PM AND IF IT DOES NOT...ISSUE FFA FOR SOUTHERN COUNTIES. SE PA AND LOWER SUSQ WILL SEE RAIN AFTER SUNSET. AREA APPRS CAPPED AFTER CFROPA BUT COOL POOL AT 50H SHUD MOVE OVR TONITE AND DESTABILIZE THIS REGION. GUIDANCE NUMBERS ARE LOW IN THIS REGION AND BACK BUILDING IS POSSIBLE AS WARM MOIST AIR RETURNS ON LLJ DEVELOPING AHEAD OF VORT MAX THIS EVENING. WE FINALLY START DRYING OUT WED WITH TROPA AND SUBSIDENCE ON BACK SIDE...SUN WILL BE MORE PREVALENT. CANT RULE OUT THE CHANCE OF A TSHR THOUGH AS THERE WILL BE SOME RESIDUAL MOISTURE. BUT THESE WILL BE OF THE POPCORN VARIETY AND WILL NOT PRODUCE ANY HEAVY RAIN. MODEL SOUNDING TOMORROW IS SLIGHTLY CAPPED BUT THERE WILL BE MORE SFC HEATING. SO A 30 POP MIGHT NOT BE A BAD IDEA. HEAD
