What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Binghamton, NY wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 25, 2:30 AM EDT, 46 minutes earlier.

Area forecast discussion, Aug 25, 2:30 AM EDT, 46 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
230 AM EDT THU AUG 25 2011

.SYNOPSIS...
A LOW PRESSURE CENTER MOVING THROUGH ONTARIO WILL DRAG A COLD
FRONT ACROSS NY AND PA LATER TODAY. THE FRONT WILL CAUSE
THUNDERSTORMS OVER OUR REGION, WITH THE POTENTIAL FOR HEAVY
DOWNPOURS. HIGH PRESSURE AND FAIR WEATHER WILL RETURN LATE TONIGHT
INTO FRIDAY.

&&

.NEAR TERM /THROUGH TODAY/...
A SMALL WEDGE OF INSTABILITY EXISTS FROM NORTH CENTRAL PA TOWARD
THE CENTRAL SO TIER REGION OF NY. ATTM A LINE OF THUNDERSTORMS IS
APPROACHING STEUBEN COUNTY. IF THERE IS TO BE SEVERE THUNDERSTORM
POTENTIAL, IT WILL MOST LIKELY BE WITH THIS LINE. THE LARGE AMOUNT
OF STRATIFORM RAIN BEHIND IT SHOULD STABILIZE THE ATMOSPHERE.

SHOWERS AND SCATTERED THUNDERSTORM ACTIVITY WILL CONTINUE THROUGH
SUNRISE.

THIS AFTERNOON...A COLD FRONT WILL SLOWLY PUSH ACROSS THE REGION.
SOLID BULK SHEAR WILL EXIST THROUGH THE LOWER ATMOSPHERE, WITH
0-6KM IN THE 30-40 KT RANGE. THE MAIN QUESTION IS WITH REGARD TO
INSTABILITY. EARLIER ACTIVITY WILL HAVE STABILIZED THE ATMOSPHERE
OVER THE WESTERN FA...BUT THERE WILL BE AN OPPORTUNITY TO RECOVER
BY MID AFTERNOON.

GIVEN BREADTH OF CLOUD COVER ALONG THE FRONT, I AGREE WITH LATEST
NAM12 RUN WHICH KEEPS BEST INSTABILITY CONFINED TO SOUTHERN PA AND
NJ.

MAIN THREAT OVER OUR REGION WILL BE FOR HEAVY RAIN. PWATS ARE
FORECAST TO BE AROUND 1.70 INCHES, AND MBE VECTORS SUGGEST
TRAINING IS POSSIBLE. SEVERE THREAT EXISTS BUT WILL LEAN TOWARD A
HEAVY RAIN SCENARIO IN THE GRIDS.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...

SHOWER ACTIVITY WILL BE TAPERING OFF OVER THE SOUTHEASTERN FA AT
THE ONSET OF THIS PERIOD. HIGH PRESSURE WILL BUILD ACROSS NY AND
PA, ALLOWING FOR CLEARING SKIES AND COMFORTABLE OVERNIGHT TEMPS.

LATEST GFS WANTS TO BRING IRENE WESTWARD, MUCH MORESO THAN THE
OTHER MODELS HAVE FORECAST. NOT READY TO JUMP ON THIS BANDWAGON,
BUT WE DID INCREASE POPS AND WINDS SATURDAY AND SATURDAY NIGHT TO
ACCOUNT FOR A WESTWARD TREND.

IN OUR CURRENT FORECAST, WE BRING CHC/SCT POPS INTO THE
SOUTHEASTERN HALF OF THE FA BY LATE SATURDAY AFTERNOON, THEN
EXPAND THE PRECIP WESTWARD SATURDAY NIGHT. STILL VERY MUCH
UNCERTAINTY WITH THIS STORM, AND WE WILL BE WATCHING THE NEW MODEL
RUNS CLOSELY THIS MORNING.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
SATURDAY NIGHT WILL BEGIN TO SEE EFFECTS OF IRENE WITH CLOUDS AND
INCREASE CHANCE FOR RAIN. FOR SUNDAY A LOT WILL DEPEND ON THE
TRACK OF THE STORM AND WHETHER ITS WIND AND RAIN BANDS WILL BEGIN
TO EXPAND OUT FROM THE STORM CENTER AS WELL AS HOW IT MAY INTERACT WITH
A FRONT MOVING EAST ACROSS THE GREAT LAKE REGION THAT IS EXPECTED
TO BE NEARLY STATIONARY OVER WESTERN NY SUNDAY MORNING. BY MONDAY
MORNING IRENE SHOULD BE WELL TO THE NORTHEAST AND THE FRONT WILL
HAVE PUSHED EAST TO THE COAST. UPPER LEVEL TROF OVER THE AREA
TUESDAY WITH COOLER TEMPS AND MAYBE A SHOWER. SURFACE HIGH
PRESSURE ACROSS AREA WEDNESDAY.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
VFR EARLY IN PERIOD AHEAD OF AREA OF RAIN WITH EMBEDDED TSRA
ACROSS WRN NY ATTM. RAIN WILL MOVE INTO KSYR, KELM AND KITH
GENERALLY BTWN 07 AND 09Z BFR PROGRESSING EAST TO KBGM ARND
09/10Z. AREA DOES SEEM TO BE SLOWING DOWN, SO TIMING MAY BE 1-2
HRS LATER. EXPECT OCCNL MVFR CONDITIONS AT ONSET OF PRECIP, WITH
ISOLATED LWR CONDITIONS PSBL, ESPECIALLY FROM ANY HEAVIER SHRA OR
TSRA. SHRA EXPECTED TO LINGER TIL ARND MID MORNING BEFORE BREAK
AND THEN PSBL TSRA DEVELOPMENT IN THE AFTN. FOR NOW, HAVE HINTED
AT THIS POSSIBILITY WITH CB CLD GROUP DUE TO UNCERTAINTY OF TIMING
AND COVERAGE OF ANY SHRA/TSRA.

S/SW WINDS REMAIN GUSTY ACROSS HIGHER TERRAIN EARLY OVERNIGHT 10
TO 18 KTS. WINDS WILL SETTLE TO SW 10 KT THRU MORNING, AND W TO NW
BY THUR AFTN.

OUTLOOK...

THU NGT...PSBL MVFR IN EARLY EVE SHRA/TSRA...THEN PATCHY LOW
