What forecasters said that day

NWS Binghamton, NY wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 14, 7:51 PM EDT, 15 minutes earlier.

Area forecast discussion, Aug 14, 7:51 PM EDT, 15 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
751 PM EDT TUE AUG 14 2012

.SYNOPSIS...
THIS EVENING THROUGH WEDNESDAY, LOW PRESSURE WILL TRACK FROM
WESTERN PENNSYLVANIA NORTHEAST ACROSS WESTERN NEW YORK AND THEN
INTO SOUTHERN QUEBEC. THIS SYSTEM WILL BRING SHOWERS AND
THUNDERSTORMS TO THE AREA PRIMARILY THIS EVENING. UNSETTLED
WEATHER WILL CONTINUE THROUGH WEDNESDAY BEFORE HIGH PRESSURE
BRINGS DRY AND SEASONAL CONDITIONS ON THURSDAY. ANOTHER COLD FRONT
WILL BRING A CHANCE FOR MORE SHOWERS AND THUNDERSTORMS ON FRIDAY.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
AT 4 PM...SHOWERS AND THUNDERSTORMS ACROSS THE FINGER LAKES REGION
AND CENTRAL SOUTHERN TIER WERE BECOMING MORE NUMEROUS AS SFC LOW
PRES OVER WESTERN PA MOVES INTO WRN NY. THIS ACTIVITY WILL SPREAD
ACROSS THE ENTIRE REGION THROUGH THIS EVENING. WILL CONTINUE WITH
LIKELY POPS THROUGH EARLY EVENING AND CHC FOR TSRA. ML CAPES ARE
CURRENTLY 500-800 J/KG IN THE WESTERN FA AND MODEL SOUNDINGS
SUGGEST THESE VALUES COULD INCREASE TO AROUND 1000 J/KG LATE THIS
AFTERNOON. THIS COMBINED WITH MARGINAL BULK SHEAR VALUES COULD
RESULT IN A FEW SVR TSRA THROUGH EARLY EVENING WITH GUSTY WINDS
AND LARGE HAIL.

LATER THIS EVENING WITH LOSS OF HEATING THE MINIMAL SVR WEATHER
THREAT WILL BE OVER. ALTHOUGH, SFC LOW PRES MOVING ACROSS NYS
COMBINED WITH DEEPENING UPPER LEVEL TROF WILL KEEP CHC POPS FOR
SHOWERS EVEN INTO THE LATE NIGHT PERIOD ALONG WITH AN ISOLATED TSRA.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
WEDNESDAY...H5 TROF WILL BE CENTERED OVER CNTRL NY WITH WEAK SFC
LOW OVER SRN QUEBEC AND A STRONGER SFC LOW IN THE DELMARVA. SHOWERS
WILL INCREASE WITH DIURNAL HEATING WITH THE MOST WIDESPREAD
COVERAGE EXPECTED EAST OF I81. MODEL SOUNDINGS CONTINUE TO SHOW
ONLY WEAK INSTABILITY SO WILL ONLY MENTION A SLIGHT CHC FOR TSRA.
MAX TEMPS WILL RANGE IN THE MID TO UPPER 70S.

WEDNESDAY NIGHT/THURSDAY...BRIEF UPPER LEVEL RIDGING AND SFC HIGH
PRES IN THE MID ATLANTIC WILL MAKE FOR CLEARING SKIES WEDNESDAY
NIGHT FOLLOWED BY MOSTLY SUNNY CONDITIONS ON THURSDAY. MAX TEMPS
WILL RANGE IN THE LOWER TO MIDDLE 80S.

THURSDAY NIGHT/FRIDAY...DEEP UPPER LEVEL LOW WILL DROP INTO
EASTERN CANADA WHILE A FAIRLY STRONG COLD FRONT APPROACHES OUR
WESTERN CWA TOWARD MORNING. THIS BOUNDARY WILL MOVE THROUGH THE FA
DURING THE MORNING AND EARLY AFTERNOON HOURS. THE NAM IS FASTER
WITH THIS FEATURE THAN THE GFS BUT BOTH MODELS INDICATE THE BEST
INSTABILITY WILL BE ACROSS THE EASTERN FORECAST AREA WHERE BETTER
DAYTIME HEATING MAY BE REALIZED. THIS SYSTEM BEING MUCH STRONGER
HAS MORE SUPPORTIVE KINEMATICS AND THE POTENTIAL FOR SEVERE
WEATHER DEVELOPMENT, WILL CONTINUE MENTION IN HWO.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
2 PM UPDATE...

WE WILL START OFF THE EXTENDED PERIOD UNSETTLED WITH A TREND
TOWARD DRIER BUT COOLER WEATHER OVER THE WEEKEND. BEST SHOT AT
PRECIPITATION IN THIS PERIOD WILL COME FRIDAY NIGHT WITH A FRONT
MOVING THROUGH. THE 12Z GFS AND CANADIAN ARE FASTER WITH THE
FRONT...DRYING US OUT BY 12Z SATURDAY. THE 0Z EURO IS MUCH
SLOWER AND ACTUALLY SLOWER THAN THE PREVIOUS RUNS OF THIS MODEL.
FOR NOW WILL LEAVE IN CHANCE POPS OVER THE FAR SOUTHEAST THROUGH
EARLY SATURDAY MORNING. WE MAY BE ABLE TO YANK THESE THOUGH IF THE
12Z EURO COMES IN FASTER...MORE IN LINE WITH THE OTHER LONG RANGE GUIDANCE.

WE SHOULD SEE A PERIOD OF DRY WEATHER FOR THE REST OF SATURDAY
INTO MOST OF SUNDAY BEFORE WE BEGIN TO SEE THE INFLUENCE OF A
DIGGING H5 TROF OVER THE OHIO VALLEY. BOTH THE GFS AND CANADIAN
ARE A BIT MORE AGGRESSIVE IN SENDING MOISTURE ARE WAY BY LATE
SUNDAY...WHICH MAY BE ENOUGH WITH FALLING H5 HEIGHTS FOR SOME
ISOLATED SHOWERS ESPECIALLY WEST OF I-81. STILL FEEL THE BETTER THREAT
FOR CONVECTIVE SHOWERS WITH THE UPPER LEVEL TROF WILL INCREASE
THROUGH MONDAY...BEFORE REACHING A PEAK TUESDAY WITH THE TROF AXIS
MOVING THROUGH. THE BIGGER STORY THIS WEEKEND WILL LIKELY BE THE
TEMPERATURES AS 850 TEMPS REMAIN IN THE SINGLE DIGITS...WHICH WILL
KEEP HIGHS IN THE LOWER TO MIDDLE 70S. PERHAPS A SIGN FALL IS NOT
TOO FAR AROUND THE CORNER.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
00Z UPDATE...
MOIST SOUTHWEST FLOW WITH A WAVE OF LOW PRESSURE...IS NOW CARRYING
THUNDERSTORMS ACROSS KELM-KITH-KSYR AXIS AT 00Z...BOUND FOR THE
REMAINDER OF THE TERMINALS OVER THE COURSE OF THE NEXT FEW HOURS.
IFR CONDITIONS WITH GUSTS 15-30 KTS CAN BE EXPECTED WITH THE
CELLS. ABUNDANT LOW LEVEL MOISTURE IN THE WAKE OF THE STORMS WILL
ALSO LEAD TO SOME AREAS OF IFR VIS AND/OR CIGS DURING THE PREDAWN
HOURS...ESPECIALLY 08Z-12Z AND MAINLY SOUTH OF KSYR-KRME. ON
WEDNESDAY...HEATING OF THE DAY WILL ALLOW SCATTERED SHOWERS AND
PERHAPS A FEW THUNDERSTORMS TO POP UP. CIGS WILL FLUCTUATE BETWEEN
MVFR AND LOW END VFR.

OUTLOOK...
WED NGT-FRI AM...MAINLY VFR EXCEPT FOR VALLEY FOG EARLY EACH
MRNG.
