Hail in New York, June 1, 2011

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
405 AM EDT WED JUN 1 2011

.SYNOPSIS...
A COLD FRONT WILL MOVE INTO THE REGION TODAY WHICH WILL TRIGGER
SCATTERED SHOWERS AND THUNDERSTORMS THROUGH EARLY AFTERNOON. SOME
OF THESE STORMS COULD PRODUCE HAIL AND DAMAGING WINDS IN THE
CATSKILLS AND NORTHEAST PENNSYLVANIA. DRIER AND COOLER WEATHER
WILL BUILD IN FOR THURSDAY AND FRIDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AS OF 405 AM...A WIDELY SCATTERED LINE OF SHOWERS AND THUNDERSTORMS
ALONG A PREFRONTAL TROF HAS FALLEN APART OVER THE LAST FEW
HOURS...ASIDE FROM A STORM NOW IN OSWEGO CO. PLENTY OF INSTABILITY
REMAINS ACROSS OUR AREA WITH THE LATEST SPC ANALYSIS SHOWING
MLCAPES AROUND 4000 J/KG! A WELL DEFINED CAP BETWEEN 700 AND 800
MB YESTERDAY HAS ERODED BUT STILL REMAINS IN PLACE. THIS SEEMS TO
HAVE PREVENTED ANY WIDESPREAD ACTIVITY FROM TAKING PLACE. IF ANY
STORMS DO BREAK THIS CAP...IE LIKE THE STORM NEAR OSWEGO
NOW...PLENTY OF CAPE EXISTS ABOVE THIS CAP ALONG WITH VERY
IMPRESSIVE MID LEVEL LAPSE RATES TO SUPPORT THE POTENTIAL FOR
ISOLATED SEVERE. 0-6 KM BULK SHEAR PROFILES WHICH WERE WEAK A FEW
HOURS AGO ARE INCREASING WITH THE APPROACH OF THE MAIN COLD
FRONT...WITH VALUES BETWEEN 40 AND 50 KTS BY 12Z. BOTTOM-LINE IS
CONVECTION IS EXPECTED TO BE ISOLATED TO WIDELY SCATTERED THROUGH
DAYBREAK BUT ANYTHING THAT DOES FORM HAS PLENTY OF POTENTIAL TO
TAP INTO. THE LATEST HRRR ILLUSTRATES THIS QUITE WELL WITH TWO
BROKEN LINES OF CONVECTION...THE FIRST NOW WITH THE PREFRONTAL
TROF...AND THE 2ND NEAR 12Z WITH THE APPROACH OF THE FRONT OVER
OUR WESTERN AND CENTRAL AREAS.

AFTER A BRIEF LULL IN ACTIVITY THROUGH MID-MORNING...A LINE OF
MORE ORGANIZED CONVECTION WILL BECOME MORE LIKELY FROM MIDDAY
THROUGH AFTERNOON ALONG THE FRONT ITSELF...FROM THE CATSKILLS
DOWN INTO NEPA. THIS AREA REMAINS IN A SLIGHT RISK FROM SPC. VERY
IMPRESSIVE SEVERE WEATHER PARAMETERS CAN BE FOUND WITH CAPES BACK
UP AROUND 3000 J/KG...0-6 KM BULK SHEAR VALUES OF 50 KTS...AND
PLENTY OF DRY AIR IN THE MID LEVELS. CHECK OUT THE BUFKIT PROFILES
FOR KAVP ON THE NAM AT 5 PM. LARGE HAIL (HIGH CAPE VALUES...WITH
FAT CAPE IN THE HAIL GROWTH REGION (-20C)...AND DAMAGING WINDS
(VERY DRY AIR IN THE MID LEVELS) ARE THE MAIN THREATS. ANY
CONVECTION SHOULD MOVE EAST AND OUT OF THE AREA BY 0Z.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/...
AS OF 405 AM...HIGH PRESSURE WILL BUILD INTO THE REGION LATER TONIGHT
THROUGH FRIDAY WITH MUCH MORE COMFORTABLE WEATHER EXPECTED.
OVERALL THE PERIOD WILL FEATURE SUNSHINE BUT SOME EXTRA CLOUDS ARE
POSSIBLE ON THURSDAY AS A H5 TROF MOVES TO OUR NORTHEAST OVER
MAINE. TEMPS WILL BE BELOW NORMAL ON THURSDAY WITH HIGHS HOLDING
IN THE 60S. IN FACT BOTH MET AND MAV GUIDANCE SHOW TEMPS DROPPING
INTO THE 30S EARLY FRIDAY MORNING IN OUR COLDEST SPOTS WITH SOME
PATCHY FROST NOT OUT OF THE QUESTION.

TEMPS BEING TO REBOUND FRIDAY AS HIGH PRESSURE SLIDES TO OUR
SOUTH AND A RETURN FLOW BEGINS TO SET UP. IT APPEARS THAT ANY
PRECIPITATION FROM AN APPROACHING WARM FRONT WILL HOLD OFF UNTIL
LATE FRIDAY NIGHT AT THE EARLIEST FOR OUR AREA.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
UPDATED AS OF 330 PM...INCREASING CHANCES FOR SHOWERS AND
THUNDERSTORMS OVER THE WEEKEND AS A TANDEM WARM AND COLD FRONTAL
SYSTEM MOVES THROUGH. THE SHOWERS AND STORMS MAY ARRIVE AS EARLY
AS FRIDAY NIGHT BUT FOR NOW HAVE IT DRY. CHANCES CAN BE EXPECTED
AHEAD OF THE WARM FRONTAL PASSAGE ON SATURDAY...AND THEN COLD
FRONTAL PASSAGE ON SUNDAY. WITH THE CONTINUED NORTHWEST FLOW ALOFT
MOISTURE WILL BE LACKING. MEDIUM RANGE MODELS SEEM TO BE IN
FAIRLY GOOD AGREEMENT WITH THESE IDEAS AND HPC GUIDANCE FRONTAL
PROGS LOOK REASONABLE AS WELL. HIGH PRESSURE RETURNS FOR MONDAY
WITH DRIER WX...FOLLOWED BY A WEAK FRONT AND SHOWERS AGAIN IN
NORTHWEST FLOW FOR TUESDAY. TEMPERATURES WILL BE NEAR NORMAL
THROUGHOUT.

&&

.AVIATION /07Z WEDNESDAY THROUGH SUNDAY/...
UPDATED AS OF 145 AM WED... MAINLY VFR EXPECTED THROUGH 06Z THU.
POTENTIAL EXCEPTIONS ARE KITH/KELM/KBGM AT THE START OF THE PD
(THROUGH 08-09Z)...WHERE PATCHY BR/HZ WILL BE AT PLAY. ALSO...LATER
THIS MORNING INTO EARLY AFTN...BRIEF RESTRICTIONS ARE POSSIBLE IN
SCTD SHRA/TSRA. DUE TO UNCERTAIN COVERAGE...WE'LL INCLUDE CB
GROUPS FOR NOW...AND ADD SHRA/TSRA FOR INDIVIDUAL SITES AS NEEDED.

S TO SW WINDS THIS MORNING 5-10 KT...WILL BECOME QUITE STG AND
GUSTY THIS AFTN FROM THE W (GUSTS OF 25-30 KT). WINDS SHOULD
GRADUALLY DIMINISH AFTER 00Z THU.
