AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 158 PM EDT THU MAY 30 2002 WILL DEVIATE FROM THE ETA IN THE 1ST PD AS THE MODEL INSISTS ON INCRSG AND STRENGTHENING THE WEAK BAND OF SHWRS OVER NY AND PA. MODEL ERROR SEEMS TO BE IN THAT THE ETA DVLPS A STRONG AREA OF LOW LVL CONVERGENCE OVER SERN NY WHILE THE LATEST SFC ANALYSIS SHOWS ONLY LGT SE WINDS NEAR THE CST...LGT SW ELSEWHERE. LACK OF A WELL DEFINED CONVERGENCE BNDRY SHD ALLOW CONV TO REMAIN SCT SO...WILL GO CLSR TO MOS GUID CHANCE POPS TNGT. FRI WILL BE INTRSTG...TO SAY THE LEAST. LOOKS LIKE SOME MRNG LGT TRWS/SHWRS WILL GIVE WAY TO CLRG...FLWD BY A FAST MVG AREA OF LINE OF TRWS ASSOCIATED WITH THE SFC COLD FNT AND STRONG UPPER LVL SHRT WV. REAL QUESTION REGARDING THE SVR RISK WILL BE THE AMT OF CLRG AND HTG THAT OCCURS AFTER THE MRNG LOW CLDS/FOG/SHWRS/TRWS AND CAN THE ATMOSPHERE RELOAD. NRN ZONES ARE MORE UNDER THE INFLUENCE OF THE SHRT WV WHILE THE SRN ZONES WILL HAVE BETTER LOW LVL CONVERGENCE AS THE FNT IS BETTER DEFINED...AND HAVE A BETTER OPPORTUNITY FOR HTG. UPPER WIND FIELDS ARE NOT AS IMPRSV AND HELICITY IS DOWN A BIT IN THE LATEST RUN. CAPES SEEM TO BE A BIT LWR TOO. FAST MVG FNT SHD ELIMINATE THE CHANCE OF SHWRS FRI EVE IN ALL BUT THE FAR SERN ZONES. SAT LOOKS TO BE A FINE DAY WITH PLENTY OF MRNG SUN...AFTN HRS MAY FEEL THE EFFECTS OF A SHRT WV ZIPPING THRU AND INCRS THE CHANCE OF CLDS AND PSBLY EVEN A SHWR/TRW. .BGM...NONE. MORFORD
