AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 925 PM EST MON MAR 12 2001 MID LEVEL MOISTURE SURGING IN THIS EVENING. THIS IS EVIDENT NOT ONLY ON THE BUF SOUNDING (+8 JUST ABOVE 850 MB)...BUT THE EXPERIMENTAL GPS WATER VAPOR RETRIEVAL SYSTEM AT SYR INDICATED THE INTEGRATED PRECIPITABLE WATER INCREASED FROM 0.4 TO 1.2 CM IN 2 HOURS. THIS HAS KEPT SURFACE TEMPERATURES FROM FALLING THIS EVENING...DESPITE DEW POINTS IN THE TEENS MOST PLACES. ALSO...DESPITE THE LOW DEW POINT DEPRESSIONS...ONLY MODERATE TEMPERATURE DROPS HAVE BEEN OBSERVED AS THE PRECIPITATION HAS MOVED INTO WESTERN AND CENTRAL PA. IT HAS BEEN MORE OF A CASE OF THE DEW POINTS RISING. MOST IMPORTANT HOWEVER...IS THAT TERRESTRIAL (E.G. GROUND SURFACE) TEMPERATURES ARE REMAINING WARM. THIS REALLY LIMITS THE THREAT OF SUBSTANTIVE GLAZE ACCRETION. VERY IMPRESSIVE JET SURGING INTO WV THIS EVENING GENERATING AN EXPANDING AREA OF PRECIPITATION ACROSS THE CENTRAL APPALACHIANS. RUC AND 18Z ETA CAPTURE THIS NICELY AND TRACK IT ACROSS OUR SOUTHEAST ZONES. THIS FOLLOWS PREVIOUS FCST THINKING AND STILL LOOKS GOOD. TEMPS ACROSS SYR/UCA AREA ALREADY BELOW FREEZING SO FZRA A GOOD BET THERE. HOWEVER HEAVIER PRECIP WILL STAY SOUTH OF THIS AREA SO WILL KEEP ADVISORY THERE. ACROSS THE CENTRAL SOUTHERN TIER STILL EXPECT SOME PATCHES OF FZRA SO WILL KEEP ADVISORY BUT WILL DOWNPLAY. SAME IS TRUE FOR AVP AREA WHICH WILL SEE MOSTLY RAIN. WILL DROP WARNING THERE BUT WILL STICK WITH ADVISORY AND EMPHASIZE FZRA IN RURAL AREAS. WILL ALSO SCALE WARNING BACK TO ADV FOR BGM/CRT/OIC AREAS. THERE WILL BE SOME FREEZING RAIN...BUT GROUND CONDITIONS ARE JUST TOO WARM FOR SUBSTANTIVE GLAZE ACCUMULATION. THE POCONOS/WRN CATSKILLS ARE A TOUGHER CALL...ESPECIALLY SINCE THIS IS WHERE THE GREATEST QPF WILL FALL. MSV/MPO JUST HIT 32. MESONET SITES LOCH SHELDRAKE (SULLIVAN CO) IS 30 AND SHAHOLA (PIKE) IS 33...WHILE 2 WAYNE COUNTY SITES ARE 36 AND 38. WILL STAY THE COURSE AND KEEP WARNING GOING HERE. .BGM...
