Area forecast discussion, Oct 5, 8:52 PM EDT, 56 minutes before
CENTRAL PENNSYLVANIA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 845 PM EDT THU OCT 5 1995 VAD WINDS ON KCCX 88D STILL SHOWING 5K FEET WINDS SCREAMING ALONG AT 50 KTS. STILL SOME LOW LEVEL VEERING...BUT NOT NEARLY AS IMPRESSIVE AS EARLIER TONIGHT...IMPLYING HELICITY VALUES DROPPING. JUST GOT A CALL FROM A SPOTTER IN GREENCASTLE (FRANKLIN CO) OF WINDS GUSTING TO NEAR 50. THE BIG QUESTION WITH THE WIND ADVISORIES IS WHETHER OR NOT ANY OF THE 50K WINDS WILL MIX DOWN TO THE SURFACE...AND THEREFORE REQUIRE THE ADVISORIES TO BE EXTENDED. OTHER THAN THE ISOLATED REPORT MENTIONED ABOVE...HAVE NOT HEARD ANYTHING ABOUT STRONG WINDS. ALL WIND ADVISORIES NOW SLATED TO EXPIRE AT 1000 PM. GIVEN ISOLATED NATURE OF HIGH WINDS... WOULD ELECT TO DROP ADVISORIES...BUT STILL KEEP THE MENTION OF STRONG GUSTS ALONG THE HIGHER ELEVATIONS. ANOTHER SPOTTER CALL JUST IN AT 830 PM UNDER ONE OF THE HEAVIEST CELLS JUST SOUTHEAST OF CTP REPORTS TORRENTIAL RAINS...BUT NOTHING MUCH IN THE WAY OF GUSTY WINDS. THIS LAST BATCH OF RAIN OVER CENTRAL PA REALLY SEEMS TO BE THE END OF ANY ORGANIZED RAIN...WITH CELLS MOVING TO THE NE AT 40-50 KTS. HAVE TO RUN...WITH POTENTIAL NASTY CELLS STARTING TO POP OVERHEAD. GOT AN ISOLATED LIGHTNING FLASH OUT THE WINDOW. JUNG
