AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 242 PM EDT FRI AUG 27 2004 .SYNOPSIS... BIG PICTURE...LONG RANGE MODELS STILL INDICATE A DISRUPTION TO THE LONG TERM +PNA PATTERN OVER THE NEXT FEW DAYS...WHICH WILL ALLOW 500 MB RIDGE TO DEVELOP OVER THE CONUS. HOWEVER GFS INDICATING SIGNS THAT THIS WILL PROBABLY ONLY BE TEMPORARY...AS COLD CORE LOW REDEVELOPS OVER HUDSONS BAY. && .SHORT TERM... LATE AFT/TONIGHT...ETA FAMILY INDICATING THAT LINE OF CONVECTION WILL DEVELOP THIS AFTERNOON ACROSS WRN AND TRACK E ACROSS CWA THIS EVENING. GFS ONLY HINTS AT THIS. A LINE OF CONVECTION ACTUALLY IS FIRING FROM N OF LK ONTARIO INTO NRN OH...SO WILL ASSUME THAT THIS BAND DOES GET GOING AND TRACKS INTO WRN NY...THUS WILL MAINTAIN THE CHC POPS BUT ONLT FOR THE PART OF TONIGHT...AS ONCE BAND GOES THRU...SHOULD BE BE SOME TEMPORARY SUBSIDENCE BEHIND IT. ONE THING TO NOTE IS THAT VERTICAL WIND PROFILES ACROSS WRN ZONES SHOW GOOD DIRECTIONAL SHEAR (THOUGH VELOCITIES ARE NOT THAT IMPRESSIVE)...AND CAPE COULD APPROACH 2000 J/KG. IF SOME FORM OF CONVECTION DOES GET GOING...IT/LL HAVE TO BE WATCHED CLOSELY...PARTICULAR INTO THE EARLY EVE. SAT...SOME CONTINUED MODEL DIFFS HERE...WITH THE GFS DEVELOPING A DEEPER SFC LOW JUST SOUTH OF THE GREAT LAKES...WHICH ENHANCES LL CONVERGENCE ACROSS THE ENTIRE CWA AS IT MOVES INTO RIDGE. THE ETA DEPICTS A WEAKER SFC LOW...AND LESS IN THE WAY OF DYNAMICS. PREFER THE ETA AS THE GFS SEEMS TO BE EXHIBITING SOME CONVECTIVE FEEDBACK...AS IT PRODUCES EXTREME UPPER LVL DIVERGENCE OVER THE MIDWEST SAT MORNING...WHICH MAY BE THE REASON FOR THE OVER DEVELOPMENT OF SFC LOW. WILL KEEP THE CHC POPS IN NWRN ZONES DUE TO CLOSER PROXIMITY TO SFC FRONT AND SFC WAVE...AND JUST THROW CHC POPS IN THE AFT IN SE ZONES DUE TO INSTABILITY. SAT NIGHT...FIRST WEAK SFC WAVE WILL HAVE HELD UP PROGRESS OF SFC FRONT...WHICH SHOULD STILL BE NW OF CWA...THEREFORE WILL CONTINUE THE CHC POPS ACROSS THE NW...BUT LEAVE THE SE ZONES DRY. SUN...ANTICYCLONIC FLOW ALOFT SHOULD HOLD THE FRONT TO THE WEST MOST OF THE DAY UNTIL MORE SIGNIFICANT (BUT LIFTING) 500 MB TROUGH APPROACHES. THEREFORE...WILL CONTINUE WITH THE SAME PRECIP PATTERN...BUT GO WITH AFTERNOON CHC IN THE SE...DUE TO BOTH FALLING HEIGHTS AND INSTABILITY. WILL INCREASE CHC POPS IN THE NW FOR SIMILAR REASONS. -CEMPA && .LONG TERM... STALLED FNT WILL BRING SHRA/TSRA SUN NGT AND MON, LIKELY ENDING FROM W TO E ON MONDAY NGT. AFTER THAT, THE POSSIBILITY OF AN EXTENDED PD OF WARM AND DRY WX WITH HIGH PRES IN CONTROL. && .AVIATION... PLAYED PSBLTY OF A LINE OF TSRA INTO WRN SITES (SYR/ELM/ITH) ARND 00Z-02Z GIVEN RDR TRENDS AND MESOETA DATA. OTRW WELL SEE VSBYS GNRLY 4-6SM IN HZ, WITH PATCHY MVFR CIGS AT TIMES (2500 FT). && .BGM WATCHES/WARNINGS/ADVISORIES... NY...NONE. PA...NONE. &&
