Area forecast discussion, Mar 8, 12:47 PM EST, 6 hours 54 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 1245 PM EST WED MAR 8 1995 ...WILL CONCENTRATE ON AFTERNOON/TONIGHT FCST... LARGE SWATH OF SNOW/RAIN CONTINUES ORIENTED UP AND DOWN THE APPLACHIANS WITH THE HEAVIEST PRECIP W OF MTNS FOR NOW. A BATCH OF RW AHEAD OF MAIN BAND OF PRECIP HAS SLIPPED IN SERN PA FROM VA. RAIN/SNOW LINE APPEARS TO RUN FROM CNTRL POTTER CNTY S TO JST SOMERSET AREA AS OF 12 PM. BAND OF PRECIP BEHIND FRNT AS MENTIONED PRVS DSCN SEEMS TO BE WELL CORRELATED WITH SWATH OF STRONG 850 MB FRONTOGENISIS. PRECIP SEEMS TO BE HVG A HARD TIME ADVECTING NEWRD INTO CNTRL AND SC MTNS OF PA PROBABLY BECAUSE OF HIGHER MTNS TO THE SW ACRS WRN MD AND ERN WV. IN TIME... HEAVIER STEADIER PRECIP SHUD WORK INTO CNTRL PA THIS AFTRN. BOTH NGM/ETA SLIDE THIS STRONG 850 MB FRONTOGENITIC REGION E WITH THE AXIS OF MAXIMUM FRCG RUNNING ABT SYR-UNV-ROA BY 00Z. THINK HEAVIEST SNOW/RAIN FROM FRONTAL FRCG WILL RUN FROM CNTRL NY SOUTHWARD ACRS SUS VLLY AND CNTRL PA BY 00Z. MODELS ALSO SHOW THAT S RATHER SFC WV DEVELOPING ON FRONT AND MOVG NEWRD UP THROUGH ERN VA THIS EVE. THIS SFC WV AND ASSCTD Q-G FRCG WILL ONLY ADD TO AN ALREADY POTENT MESO-SCALE SET UP THAT WILL BE ACRS CNTRL/ERN PA THIS AFTRN/EVE. THINK HEAVY PRECIP AT TIMES WILL BE OCCURRING IN THESE AREAS FROM 18Z-06Z. THIS SFC WV WILL ALSO ADVECT ENUF MOISTURE INTO SERN PA TO PRODUCE HEAVY RAINS THERE BETWEEN NOW AND 00Z. RAIN/SNOW LINE WILL BE A NIGHTMARE IN CNTRL/ERN PA. IT ALL DEPENDS ON HOW MUCH COLD AIR CAN MOVE E OF MTNS. 0 C ISOTHERM AT 850 MB AS SEEN ON THIS MORN/S UPR AIR PLOTS AND IN THE INITIAL GRIDDED DATA SEEMS TO CORRELATE WELL TO R/S LINE. WITH SFC WV ADVANCING N ALONG FRNT TO THE S OF PA THIS AFTRN/EVE... THINK 0C LINE AT 850 MB WILL COME TO A TEMPORARY HALT UNTIL WV PASSES. ETA SOLTN IS FURTHER W WITH 0C LINE THAN NGM. LIKE ETA SOLTN SINCE MODELS ALWAYS SEEM TO BRING COLD AIR E OF MTNS TOO QUICKLY. ETA IS ALSO SUPPOSED TO HV BETTER TOPOGRAPHY THAN NGM. THUS... SEE RAIN TURNING TO SNOW IN CNTRL AND SC PA (MAINLY PIT CTP ZONES) THIS AFTRN WITH 3 TO 6 INCHES OR SO LOOKING PRETTY GOOD MOST AREAS BY LATE EVE. CONCUR WITH WINTER WX ADVY WRN CTP FA AND LIKELY WILL HV TO EXTENT FOR THIS EVE FOR MUCH OF WRN CTP FA. NRN COUNTIES OF ERN CTP FA (PHL ZONES)... LOOK LIKE THEY WILL ALSO TURN TO SNOW THIS AFTERNOON LOOKING AT ELM OBS AND WITH ALL THE HIGHER TERRAIN UP THERE TO BOOT. COLD AIR MAY NOT GET INTO SULLIVAN CNTY IN TIME THIS AFTRN BUT LATER TONIGHT I THINK IT WILL BE SNOWING GOOD UP THERE. CONCUR WITH WINTR WX ADVY ALSO AND LIKELY WILL HV TO EXTENT INTO EVE ALSO. WUD BUMP SNOW AMOUNTS UP THERE THROUGH THIS EVE. I WOULD GO TOTAL 3 TO 6 INCHES OR SO TOO THRU LATE EVE. MID SUS VLLY ABT 1 TO 3 INCHES... LESSOR AMNTS OF SNOW LATE TONIGHT LWR SUS VLLY. NO ZONES... WILL CONCENTRATE ON NOW/S ETC. NICOSIA
