NWS Binghamton, NY wrote its last area forecast discussion before the first event at May 10, 1:45 PM EST, 5 hours 2 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 245 PM EDT MON MAY 10 2004 .DISCUSSION... SURFACE WARM FRONT CUTTING ACROSS CENTRAL NEW YORK AND NORTHEAST PA EARLY THIS AFTN WITH CONVECTION DEVELOPING TO THE SOUTH WHERE HIGHER CAPES AND INSTABILITIES ARE FOUND. BELIEVE THAT ANY STORMS THAT FIRE ACROSS OUR AREA WILL BE EARLY THIS EVENING BEFORE LOSS OF DAYTIME HEATING. STILL, IT LOOKS LIKE THE BETTER CHC FOR SHRA AND TSRA WILL OCCUR LATER TONIGHT WITH THE APPROACH OF COLD FRONT. THE FRONT ITSELF DOES NOT APPROACH THE NORTHWEST PART OF THE FORECAST AREA UNTIL NEAR 12Z ON TUESDAY, SO WILL KEEP THE SOUTHEAST PART OF OUR ZONES DRY FOR THE OVERNIGHT. TUESDAY...THE FRONT WILL PUSH SOUTH ACROSS THE CWA DURING THE MORNING AND STALL ACROSS NORTHERN PA AS HIGH PRESSURE TO THE NORTH MOVES ACROSS EASTERN CANADA. THIS WILL HELP TO KEEP THE NORTHERN PART OF THE FORECAST AREA DRY WHILE THE CHC FOR PRECIP REMAINS ACROSS THE SOUTH HALF OF OUR AREA CLOSER TO THE FRONT. THE INSTABILITY WILL BE THERE...BUT THERE WILL BE LITTLE IN THE WAY OF DYNAMICS TO SUPPORT MORE THAN JUST LOW CHC POPS. TUESDAY NIGHT-WEDNESDAY...WILL KEEP TUES NIGHT DRY WITH LOSS OF DAYTIME HEATING HELPING TO KILL OF ANY TSRA THAT DEVELOP IN THE VACINITY OF THE FRONT DURING THE DAY. ON WEDNESDAY...UPPER RIDGE BEGINS TO BUILD MORE ACROSS THE EAST WHILE HIGH PRESSURE TO THE NORTH MOVES EAST AND PHASES WITH BURMUDA HIGH OFF THE COAST. FRONTAL ZONE STILL TO THE SOUTH MAY CONTINUE TO DEVELOP DIURNAL CONVECTION, BUT NO DYNAMICS TO SUPPORT MUCH MORE THAN LOW CHC POPS IN THE FORECAST. && .EXTENDED (WED NITE-MON)... FIRST HALF OF THIS PERIOD WILL FIND FORECAST AREA UNDER THE PERIPHERY OF A STRONG BERMUDA RIDGE WITH ENERGY FROM THE WESTERLIES SHUNTED WELL TO OUR NORTH AND WEST. SFC WARM FRONT WILL HAVE JUST PASSED THE AREA WEDS NITE-EARLY THURS WITH POSSIBLY SOME UPR LVL ENERGY MOVING THRU THE REGION. ALONG WITH DAYTIME INSTABILITY BELIEVE THERE WILL STILL BE A NOMINAL CHC FOR SHRA/TSRA ON THURS... AND PERHAPS MOST OF THAT EVEN EARLY. LATER THURS AND ESPLY FRI...GFS HOLDS A LOT OF MOISTURE AND INSTABILITY ON THE NORTH SIDE OF THE RIDGE...THEREFORE DVLPG AN ABUNDANCE OF CONVECTIVE PRECIP. INSTABILITY MAY BE REALIZED GIVEN EXPECTED SFC TEMPS...BUT WITHOUT INDICATION OF APPRECIABLE TRIGGER...MDL GENERATED PCP SEEMS OVERDONE. I SUSPECT THERE WILL BE SOME ISOLD AFTERNOON CONVECTIVE DEVELOPMENT...BUT THIS FALLS INTO THE CLIMO NORM...SO AT THAT FCST RANGE...WILL GO PREDOMINANTLY DRY. RIDGE BREAKS DOWN FOR THE LATTER HALF OF THE PERIOD...ALLOWING COLD FRONT INTO THE AREA SATURDAY AFTERNOON INTO EARLY SUNDAY FOR NEXT GOOD CHC OF TSRA/SHRA. COOLER HIGH PRESSURE REPLACES THIS FEATURE FOR A RETURN TO RELATIVELY DRIER WEATHER AND MORE SEASONABLE TEMPERATURES FOR DAYS 6 AND 7. && .AVIATION... GENERALLY SCT-BKN VFR CONDITIONS ARE EXPECTED FOR ABOUT THE FIRST 18 HOURS OF THE FCST. DURING THIS TIME...A COUPLE ROUNDS OF THUNDERSTORMS ARE EXPECTED TO AFFECT EACH TERMINAL. FIRST BATCH EXPECTED ROUGHLY DURING THE 21Z-01Z TIME FRAME AS WEAK DISTURBANCE MOVES FROM GTLKS RGN ACROSS OUR AREA WHICH IS BCMG INCRGLY UNSTABLE WITH WARM FRONT IN VICINITY. SECOND ROUND IS EXPECTED ALONG AND AHEAD OF COLD FRONT LATER TONIGHT (AFT 06Z). CIGS/VSBYS MAY LOWER AT ITH/BGM BEHIND THE COLD FRONT TO MVFR WITH SHOWERS. GRDL IMPROVEMENT TO VFR CIGS IS EXPECTED AFT 16Z. && .BGM WATCHES/WARNINGS/ADVISORIES... NY...NONE. PA...NONE. SHORT TERM...JML AVIATION...JAB EXTENDED...JAB
