Hail and Damaging Wind in New York, July 6, 2011

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
204 PM EDT WED JUL 6 2011

.SYNOPSIS...
WARM SUMMER-LIKE WEATHER WILL OCCUR TODAY WITH TEMPERATURES
APPROACHING 90 ACROSS SOUTHERN NEW YORK AND NORTHERN PENNSYLVANIA.
A COLD FRONT WILL BRING SCATTERED THUNDERSTORMS LATER THIS
AFTERNOON THROUGH THIS EVENING... THEN DRYER AND SLIGHTLY COOLER
WEATHER WILL RETURN LATE TONIGHT. THURSDAY THROUGH FRIDAY WILL BE
SLIGHTLY COOLER THAN TODAY WITH ISOLATED SHOWERS AND
THUNDERSTORMS... MAINLY DURING THE AFTERNOON.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
UPDATED AT 10 AM...MINOR CHANGES TO ACCOUNT FOR LATEST OBS/TRENDS.
NO OTHER CHANGES. BEST CHC FOR ANY TSRA DEVELOPMENT LOOKS TO BE
AFTN 3 PM TODAY AS WEAK CD FRNT APPROACHES. PARAMETERS NOT ALL
THAT FAVORABLE FOR SVR, BUT KEEPING IN CHC FOR GUSTY WINDS, MAINLY
NORTH GIVEN SLGT RISK AND BETTER SHEAR ACROSS NE NYS INTO NEW
ENGLAND.

UPDATED AT 7 AM... JUST A FEW MINOR CHANGES TO ACCOUNT FOR LATEST
TRENDS. SKIES WILL REMAIN MOSTLY CLEAR THROUGH ABOUT 10 AM... THEN
CLOUDS SPREAD IN FROM THE WEST. HAVE ADDED A MENTION OF GUSTY
WINDS ACROSS THE NORTHERN COUNTIES FROM MID AFTERNOON THROUGH
EARLY EVENING AS THAT IS THE AREA WHERE SHEAR WILL BE STRONGEST
AND MAY BE SUPPORTIVE OF SOME MARGINALLY SEVERE STORMS.

LATEST SATELLITE IMAGE SHOWS LOTS OF CLEAR SKY ACROSS NY/PA EARLY
THIS MORNING... INDICATING THE POTENTIAL FOR LOTS OF SUNSHINE
LATER THIS MORNING INTO EARLY THIS AFTERNOON. SEVERAL HOURS OF
SUNSHINE WILL ALLOW TEMPERATURES TO CLIMB WELL INTO THE 80S IN ALL
AREAS. HIGHS NEAR 90 YESTERDAY ACROSS SOUTHERN MICHIGAN INDICATES
THAT A FEW 90 DEGREE READINGS WILL BE POSSIBLE LATER TODAY AT
LOWER ELEVATIONS IN SOUTHERN NY AND NORTHERN PA.

STRONG DIURNAL HEATING WILL ALLOW FOR THE DEVELOPMENT OF MODERATE
INSTABILITY LATER TODAY WITH CAPES RISING TO 500 TO 1000 J/KG IN
MANY AREAS WITH AS MUCH AS 1500 J/KG POSSIBLE ESPECIALLY OVER
NORTHERN PA. MODEL FORECASTS INDICATE DEEP LAYER SHEAR INCREASING
TO 30 TO 35 KTS OVER CENTRAL NY LATER TODAY WITH 20 TO 25 KTS OVER
NORTHERN PA. THIS COMBINATION OF CAPE AND SHEAR WILL BE ENOUGH TO
SUPPORT A FEW SEVERE STORMS LATER TODAY THROUGH THIS EVENING AS 10
TO 30 M 12 HR 500 MB HEIGHT FALLS OVERSPREAD A LEE TROUGH AND
SURFACE COLD FRONT SWEEPING SOUTHEAST ACROSS THE AREA THIS
EVENING. SPC SLIGHT RISK OVER EASTERN NY LOOKS REASONABLE AND
COULD EVEN BE EXPANDED SLIGHTLY SOUTHWESTWARD ACROSS CENTRAL NY
GIVEN MARGINALLY FAVORABLE CAPE/SHEAR AND LARGE-SCALE FORCING.
PWAT VALUES GREATER THAN 1.5 INCHES WILL ALSO SUPPORT SOME HEAVY
DOWNPOURS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/...
THE FRONT WILL CLEAR THE AREA THIS EVENING FOLLOWED BY DRYER AND
SLIGHTLY COOLER WEATHER LATE TONIGHT THROUGH THURSDAY MORNING. THE
FRONT WILL STALL OVER THE CENTRAL MID-ATLANTIC REGION THURSDAY
AFTERNOON THROUGH FRIDAY. ISOLATED SHOWERS MAY DEVELOP AS FAR
NORTH AS SOUTHERN NY THURSDAY AFTERNOON... THEN FRIDAY AFTERNOON
WILL FEATURE A SOMEWHAT BETTER CHANCE OF SHOWERS AND THUNDERSTORMS
AS AN UPPER WAVE ROUNDS THE BASE OF THE LARGE-SCALE TROUGH OVER
THE GREAT LAKES AND ENHANCES PRECIPITATION ALONG THE STALLED
FRONT. THE NAM APPEARS TO BE OVERDONE WITH THE DEVELOPMENT OF A
SURFACE LOW ALONG THE MID-ATLANTIC COAST FRIDAY... HOWEVER THE
NAM/GFS AND LATEST 00Z ECMWF ALL INDICATE AN INCREASE IN
SHOWERS/THUNDERSTORM COVERAGE FRIDAY AFTERNOON.

FOR TEMPERATURES USED MAINLY A BLEND OF BIAS CORRECTED MAV AND MET
GUIDANCE... WITH A SLIGHT UPWARD ADJUSTMENT THIS AFTERNOON ACROSS
THE CENTRAL AND SOUTHERN COUNTIES WHERE HEATING AHEAD OF THE
APPROACHING COLD FRONT WILL BE STRONGEST.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
DUE TO WATCH ISSUANCE DISCUSSION WILL BE BRIEF. CLOSELY FOLLOWED
HPC GUIDANCE WITH ONLY VERY MINOR TWEEKS. FAIRLY ZONAL FLOW SHUD
PREVAIL WITH COLD FNTL PSSG ON MONDAY. CHC FOR SHRA/TSRA MONDAY...OTRW
FAIR WX TO PREVAIL AHEAD OF (SAT/SUN) AND BEHIND (TUE/WED) THE FNT.
TEMPS RUNNING NEAR OR SLIGHTY ABV NORMAL...WITH MAXES GNRLY L/M
80S AND MINS U50S TO M60S.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
CDFNT WILL PROGRESS ACRS THE FCST AREA LATE THIS AFTN AND EVNG.
WATCH JUST ISSUED...BUT CONFIDENCE HERE IN ANYTHING MORE THAN
ISOLD SVR IS VERY LOW. BEST CHC FOR STRONGER STORMS APPEAR TO BE
OVER THE FAR NE SXNS OF THE BGM CWA. THE SCENARIO WE HAVE GEATEST
CONFIDENCE IS WHERE WDLY SCT NON-SVR TSRA DVLP ALONG OR JUST AHEAD
OF THE FNT ARND 19Z...TRACKING SEWD DURING LATE AFTN/EVNG INTO THE
SRN TIER AND NE PA. HOWEVER THE DEGREE OF CVRG IS ALSO A BIG
QUESTION SO FOR NOW WE JUST PLAYED A 2 HR TEMPO PD DURING THE AFTN
WITH A CB GROUP. ONLY XCPTN WAS AT SYR/RME WHERE WE PLAYED A TEMPO
GROUP FOR SHRA WITH CB. UPDATES WILL BE MADE- IF NEEDED- ONCE
SITN BCMS MORE CLEAR. OTHER CHALLENGE FOR THE TAFS WAS THE POTNL
FOR LOW CLDS OR VLY FOG LATER TNGT ABD INDICATED MVFR MOST CNTRL
NY SITES LATE TNGT. VFR PREVAILS ON THU. WINDS THIS AFTN WRLY
10-20 KTS...BECMG NWLY 5 KTS TNGT AND NNWLY 10-15 KTS THU.

OUTLOOK...

THU NGT THRU SUN...MOSTLY VFR. SOME LGT VALLEY FOG PSBL EARLY
EACH AM.

MON...SCT TSRA WITH MVFR.
