The airmass across east central New York became moderately unstable during the afternoon of Wednesday July 6th, with daytime heating and an increase in low level moisture. With the approach of a disturbance in the upper levels of the atmosphere and the presence of a pre-frontal trough, convection fired up across the area with mainly damaging winds occurring with the severe thunderstorms.

The episode as NWS ALY wrote it up.
The airmass across east central New York became moderately unstable during the afternoon of Wednesday July 6th, with daytime heating and an increase in low level moisture. With the approach of a disturbance in the upper levels of the atmosphere and the presence of a pre-frontal trough, convection fired up across the area with mainly damaging winds occurring with the severe thunderstorms. There were a few reports of large hail.
Pre-frontal trough: An elongated area of relatively low pressure preceding a cold front that is usually associated with a shift in wind direction.

NWS Albany, NY wrote its last area forecast discussion before the first event at Jul 6, 12:55 PM EST, 1 hour 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 155 PM EDT WED JUL 6 2011 .SYNOPSIS... AN APPROACHING COLD FRONT WILL RESULT IN THE DEVELOPMENT OF SCATTERED SHOWERS AND THUNDERSTORMS ACROSS THE AREA THIS AFTERNOON AND EVENING. THE FRONT WILL MOVE GRADUALLY ACROSS THE AREA THIS AFTERNOON AND TONIGHT...THEN IS EXPECTED TO STALLED ALONG THE NEW ENGLAND COAST AND MID ATLANTIC REGION THURSDAY. && .NEAR TERM /THROUGH TONIGHT/... ...SEVERE THUNDERSTORM WATCH 605 IN EFFECT UNTIL 9 PM EDT... AS OF 145 PM EDT...THE APPROACH OF THE SHORTWAVE FROM THE WEST...IN CONJUNCTION WITH A PREFRONTAL TROUGH/LAKE BREEZE BOUNDARY HAS ALLOWED TSTMS TO RAPIDLY DEVELOP ACROSS THE WESTERN ADIRONDACKS. WE EXPECT THIS LINE TO CONTINUE BUILDING SOUTH...WHILE TRANSLATING E AND SE THIS AFTERNOON. AGAIN...MAIN SEVERE ATTRIBUTES EXPECTED ARE POTENTIALLY ISOLATED DAMAGING WIND GUSTS FROM EMBEDDED BOWING SEGMENTS. IN ADDITION...CAN NOT RULE OUT ISOLATED LARGE HAIL AS WELL GIVEN COOLING MID LEVELS WITH APPROACH OF SHORTWAVE...ESP GIVEN THE 500 MB -13 TO -14C NOTED ON 12Z SOUNDINGS ACROSS THE EAST CENTRAL GREAT LAKES. NORTHERN PORTIONS OF THE REGION APPEAR TO BE IN LINE FOR OVERALL BEST DEEP LAYER SHEAR AND ORGANIZED CONVECTION...WHILE SOUTHERN AREAS MAY STAND TO GET LESS SHEAR...BUT HIGHER CAPES IN CLOSER PROXIMITY TO SLIGHTLY DEEPER LOW LEVEL MOISTURE. AS FOR TIMING...EXPECT THE LINE TO CONTINUE EXPANDING...AND AFFECTING THE WESTERN ADIRONDACKS AND MOHAWK VALLEY THROUGH 3 PM...THEN THE LAKE GEORGE SARATOGA REGION...NORTHERN PORTIONS OF THE CAPITAL REGION...AND THE UPPER HUDSON VALLEY BETWEEN 3 AND 5 PM...AND ALBANY...THE BERKSHIRES...AND SOUTHERN VT MAINLY BETWEEN 5 AND 7 PM...AND PERHAPS NOT UNTIL AROUND OR AFTER 7 PM FOR SOUTHERN VT...THE SE CATSKILLS...MID HUDSON VALLEY AND NW CT. OTHERWISE...HAVE ADJUSTED POPS/TEMPS/DEWPOINTS AND WINDS ACCORDING TO RECENT OBS. PREVIOUS DISCUSSIONS FOLLOW... AS OF 1115 AM EDT...SKIES REMAIN MOSTLY SUNNY ACROSS THE REGION. WE HAVE SHAVED BACK THE TIMING OF SHOWERS/STORMS...WHICH MAY NOT DEVELOP ACROSS THE WESTERN DACKS UNTIL 1 OR 2 PM...THE LAKE GEORGE/SARATOGA REGION BETWEEN 3 AND 5 PM...AND THE CAPITAL REGION AND POINTS S AND E AND INTO SOUTHERN VT BETWEEN 5 AND 8 PM...WHICH FOLLOWS CLOSE TO THE LATEST HRRR REFLECTIVITY DEPICTION. HAVE ALSO INCREASED POPS ACROSS NORTHERN AREAS INTO THE LIKELY RANGE...WHERE AREAL COVERAGE SHOULD BE MOST NUMEROUS DUE TO BETTER UPPER SUPPORT. AS FOR SEVERE POTENTIAL...STILL LOOKS LIKE ISOLATED SEVERE STORMS A POSSIBILITY...MAINLY FROM THE ALBANY NORTH AND WEST...AS WELL AS ACROSS SOUTHERN VT...WHERE DEEP LAYER SHEAR AND OVERALL SYNOPTIC LIFT APPEARS STRONGEST. THE MAIN ATTRIBUTE TO ANY SEVERE STORMS APPEARS TO BE POTENTIALLY STRONG/DAMAGING WIND GUSTS...ESP AS COLD POOLS DEVELOP AND PROPAGATE E AND SE INTO AN INCREASINGLY HOT...MOIST AND UNSTABLE AIR MASS. AS FOR STORM MODE...IT APPEARS THAT ONCE CELLS DEVELOP TO THE W/N...THEY MAY ORGANIZE INTO MULTICELL CLUSTERS/LINES...WITH POSSIBLE EMBEDDED BOWING SEGMENTS DUE TO AFOREMENTIONED COLD POOL DEVELOPMENT/PROPAGATION. 0-6KM SHEAR NOT OVERLY IMPRESSIVE ON KBUF SOUNDING...WITH GENERALLY 25-30 KT...BUT SLIGHTLY STRONGER WINDS APPROACHING FROM THE W WITH SHORTWAVE COULD ALLOW FOR THIS TO INCREASE FURTHER...ESP ACROSS NORTHERN AREAS...ALLOWING FOR THE POSSIBILITY OF GREATER STORM ORGANIZATION. OTHERWISE...HAVE TWEAKED HOURLY TEMPS/DEWPOINTS ACCORDING TO RECENT OBS. PREVIOUS DISCUSSION FOLLOWS... AS OF 722 AM EDT...LATEST REGIONAL RADAR SHOWS SOME ELEVATED TSTM ACTIVITY NEAR THE ST. LAWRENCE VALLEY. THESE STORMS ARE MOVING NORTHEASTWARD AND AWAY FROM THE CWA...SO WILL KEEPS POP LOW ACROSS THE ENTIRE AREA THROUGH MID MORNING. AS THE UPPER TROUGH STARTS TO APPROACH THE AREA...SHOWERS AND THUNDERSTORMS WILL START TO BREAK OUT ACROSS WESTERN AREAS BY LATE MORNING AND ESPECIALLY FOR THIS AFTN FROM WEST TO EAST ACROSS THE ENTIRE AREA. THE 09 UTC HRRR GUIDANCE CONFIRMS THIS IDEA AS WELL WITH SCT ACTIVITY FOR MUCH OF THE DAY UNTIL A BROKEN LINE OF STORMS MOVES ACROSS THE CWA BY THE MID TO LATE AFTN. THE 06 UTC NAM BUFKIT SOUNDING REALLY CRANKS UP THE CAPE/PWATS THIS AFTN /UP TO 2500 J/KG OF CAPE AND PWATS OF 1.70 INCHES FOR KALB/ BUT BELIEVE IS DUE TO THE MODEL OVERDOING THE SFC/BOUNDARY LAYER TDS. THE 06 UTC GFS BUFKIT SOUNDINGS LOOK LITTLE MORE REASONABLE WITH JUST UNDER 1000 J/KG FOR KALB BY AFTN. FOR NOW...WILL NOT ADD ENHANCED WORDING INTO THE GRIDS...BUT MAY RECONSIDER FOR THE NEXT ESTF UPDATE...AFTER SEEING THE JUST LAUNCHED 12 UTC KALY SOUNDING AND ADDITIONAL RUNS OF THE HRRR/LOCAL WRF. OTHERWISE...TEMPS LOOK ON TRACK WITH NEAR 90 IN THE CAPITAL REGION BY AFTN. PREVIOUS DISCUSSION IS BELOW... THE LONGWAVE TROUGH WILL RETURN TO THE GREAT LAKES REGION AND NORTHEAST TODAY AS SHORT WAVES MOVE THROUGH THE FAST FLOW. SURFACE LOW PRESSURE OVER EASTERN CANADA WILL MOVE OFF TO THE EAST TODAY DRAGGING ITS ASSOCIATED COLD FRONT ACROSS THE REGION THIS AFTERNOON AND TONIGHT. THE BOUNDARY WILL MOVE THROUGH GRADUALLY AS THE FLOW ALOFT PARALLELS IT. IT WILL BE ANOTHER WARM/HOT DAY WITH TEMPERATURES EXPECTED TO BE A COUPLE DEGREES WARMER THAN TUESDAY WITH HIGHER DEW POINTS...RISING INTO THE LOWER TO MID 60S. THE STORM PREDICTION CENTER HAS KEPT MUCH OF THE FORECAST AREA IN THE SLIGHT RISK FOR SEVERE STORMS TODAY. WILL HAVE DECENT SOUTHWESTERLY FLOW ACROSS THE AREA...30 TO 40 KNOTS. THE QUESTION IS HOW UNSTABLE DOES IT GET IN THE PRE-FRONTAL ENVIRONMENT. THE SREF GUIDANCE INDICATE THERE IS GOOD POTENTIAL FOR MOST UNSTABLE CAPE VALUES TO REACH NEAR 1000 J/KG THIS AFTERNOON INTO THE EVENING. WILL CONTINUE TO HIGHLIGHT THREAT IN OUR HAZARDOUS WEATHER OUTLOOK. WILL NOT ADD ENHANCEMENTS FOR WIND OR HAIL TO WEATHER GRIDS THIS MORNING...CAN BE ADDED LATER TODAY. HOWEVER...PRECIPITABLE WATER VALUES ARE MODELED TO INCREASE TO 1 1/4 TO 1 1/2 INCHES SO WILL ADD ENHANCEMENT FOR HEAVY DOWNPOURS. THE THREAT FOR STORMS WILL DECREASE AS THE EVENING PROGRESSES WITH LOSS OF HEATING. && .SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/... THE COLD FRONTAL BOUNDARY WILL BE SLOW TO EXIT THE AREA AND IS EXPECTED TO STALLED ALONG THE NEW ENGLAND COAST BACK WESTWARD INTO MID ATLANTIC REGION THURSDAY. THE BOUNDARY WILL PROVIDE A FOCUS FOR CONVECTION TO FORM AS SHORT WAVES MOVE THROUGH THE UPPER TROUGH. HEIGHTS WILL VERY GRADUALLY FALL THROUGH FRIDAY NIGHT. SURFACE HIGH PRESSURE WILL TRY AND BUILD IN ON THURSDAY RESULTING IN COOLER AND LESS HUMID CONDITIONS ACROSS THE NORTHERN PORTION OF THE FORECAST AREA. HOWEVER...THE MODELS ARE COMING INTO BETTER AGREEMENT THAT A WAVE OF LOW PRESSURE WILL FORM ON THE STALLED BOUNDARY FRIDAY/FRIDAY NIGHT AND HEAD NORTHEASTWARD. SO CAN NOT RULE OUT THE THREAT FOR CONVECTION ESPECIALLY ACROSS THE SOUTHERN PORTION OF THE FORECAST AREA CLOSER TO THE BOUNDARY. EXPECTING SEASONABLE TEMPERATURES. && .LONG TERM /SATURDAY THROUGH TUESDAY/... GFS AND ECMWF ARE IN FAIRLY GOOD AGREEMENT REGARDING A SURFACE LOW OFF THE MID ATLANTIC COAST SATURDAY MORNING WHILE THE CMC HAS THE LOW CENTER MUCH FARTHER EAST OFF OF CAPE COD. AT THIS POINT NO REASON TO NO GO WITH THE HPC ANALYSIS WITH A FRONTAL SYSTEM EXTENDING ACROSS THE SOUTHERN STATES TO SOUTHEASTERN VIRGINIA AND FROM THERE NORTHEAST TO SOUTH OF CAPE COD AND HENCE OUT TO SEA. THE SURFACE LOW LOOKS TO SPREAD A FEW CLOUDS INTO OUR SOUTHERN COUNTIES...WITH JUST A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS SATURDAY...BEFORE IT MAKES ITS EXIT INTO THE ATLANTIC. THEN HIGH PRESSURE FROM THE GREAT LAKES REGION MOVES EAST AND BUILDS INTO THE REGION SATURDAY NIGHT AND SUNDAY. HIGHS SATURDAY WILL BE A TAD ON THE WARM SIDE...FROM THE UPPER 70S TO THE LOW 80S. LOWS SATURDAY NIGHT WILL BE FAIRLY PLEASANT WITH LOW TO MID 50S ACROSS THE COOLER MOUNTAIN REGIONS AND NEAR 60 IN THE HUDSON VALLEY. SUNDAY WILL BE SUNNY AND WARM...WITH HIGHS MOSTLY IN THE 80S AND LIGHT SOUTHWEST OR WESTERLY WINDS. SUNDAY NIGHT WILL BE A BIT WARMER WITH LOWS FROM THE LOW AND MID 50S IN THE MOUNTAINS TO THE LOWER 60S IN THE MOHAWK AND HUDSON VALLEYS. AN APPROACHING FRONT WILL BRING A CHANCE OF SHOWERS ALONG WITH A FEW THUNDERSTORMS STARTING MONDAY MORNING... WITH A GREATER LIKELIHOOD OF SHOWERS AS THE FRONT MOVES THROUGH THE AREA MONDAY AFTERNOON AND EVENING. THERE ARE SEVERAL INDICATORS SOME OF THE STORMS COULD BE STRONG INCLUDING MUCAPE VALUES TO 1500 J/KG AND PWAT VALUES IN EXCESS OF TWO INCHES...SUGGESTING A POTENTIAL FOR HEAVY LOCALIZED RAINFALL. INDEED MONDAY COULD BE A BIT ON THE STEAMY SIDE WITH HIGHS FROM THE MID 80S TO AROUND 90 AND DEW POINTS GETTING INTO THE UPPER 60S IN THE HUDSON VALLEY. MONDAY NIGHT WILL BE WARM AND HUMID WITH LOWS FROM AROUND 60 NORTH TO AROUND 70 SOUTH. SOMEWHAT COOLER AND DRIER AIR WILL FLOW INTO THE REGION FROM THE NORTH ON TUESDAY AS HIGH PRESSURE MOVES INTO THE GREAT LAKES STATES WITH HIGHS FROM THE MID 70S NORTH TO THE MID 80S SOUTH. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... WITH AN APPROACHING COLD FRONT...SCT SHRA/TSRA ARE BREAKING OUT ACROSS CENTRAL AND NORTHERN NY AND ATTEMPTING TO MOVE TOWARDS THE AREA EARLY THIS AFTN. ALTHOUGH FLYING CONDITIONS WILL BE VFR TO START THE TAF PERIOD...THERE IS THE POTENTIAL FOR BRIEF PERIODS OF MVFR/IFR DUE TO SHRA OR EVEN A TSTM FOR THE MID TO LATE AFTN HOURS. DUE TO THE SCATTERED NATURE OF THE TSTMS...AS WELL AS THE UNCERTAINTY IN THE TIMING AND EXTEND...WILL NOT INCLUDE TSRA/VCTS IN THE TAF AT THIS POINT...BUT WILL INCLUDE A CB APPENDAGE WITH A TEMPO FOR AN MVFR SHOWER FOR THE MID/LATE AFTN AND INTO THE EVENING. BEHIND THE COLD FRONT...THE CHC FOR SHOWERS WILL DIMINISH GREATLY AFTER ABOUT 00 UTC...AND THE CLOUDS WILL THIN IN COVERAGE AS WELL. DEPENDING ON HOW MUCH RAINFALL OCCURS TODAY...THERE WILL BE THE POTENTIAL FOR SOME MVFR MIST TONIGHT...ESP AT KGFL. THIS WILL DISSIPATE AFTER SUNRISE THURSDAY...ALLOWING FOR VFR CONDITIONS TO RETURN FOR THE ENTIRE DAY. LIGHT SOUTHERLY WINDS THIS AFTN WILL BECOME WESTERLY BY THIS EVENING. THERE MAY BE A FEW GUSTS AT TIMES THIS AFTN IN CHANNELED NORTH TO SOUTH VALLEYS...BUT SFC WINDS WILL GENERALLY BE LESS THAN 10 KTS. WESTERLY TO NORTHWESTERLY WINDS WILL DIMINISH AND BE NEARLY CALM OVERNIGHT...WHICH MAY HELP AID THE DEVELOPMENT OF MIST. AFTER SUNRISE...NW WINDS WILL PICK UP SOMEWHAT...BUT STILL GENERALLY BE LESS THAN 10 KTS THROUGH THURSDAY MORNING. OUTLOOK... THU-FRI...MAINLY VFR. CHC OF MVFR IN SHRA/TSRA AT KPOU. SAT-SUN...VFR...NO SIG WX. MON...VFR/MVFR...CHC SHRA/TSRA. && .FIRE WEATHER... AN APPROACHING COLD FRONT WILL RESULT IN THE DEVELOPMENT OF SCATTERED SHOWERS AND THUNDERSTORMS ACROSS THE AREA THIS AFTERNOON AND EVENING. THE FRONT WILL MOVE GRADUALLY ACROSS THE AREA THIS AFTERNOON AND TONIGHT...THEN IS EXPECTED TO STALLED ALONG THE NEW ENGLAND COAST AND MID ATLANTIC REGION THURSDAY. MINIMUM RELATIVE HUMIDITY VALUES OF 35 TO 45 PERCENT ARE EXPECTED THIS AFTERNOON WITH HIGHER VALUES OF 45 TO 55 PERCENT ACROSS THE SOUTHERN ADIRONDACKS...WITH A RECOVERY TO 90 TO NEAR 100 PERCENT TONIGHT. THURSDAY AFTERNOON MINIMUM RELATIVE HUMIDITY VALUES OF 35 TO 45 PERCENT ARE EXPECTED WITH A RECOVERY TO 80 TO NEAR 100 PERCENT THURSDAY NIGHT. && .HYDROLOGY... SCATTERED CONVECTION IS EXPECTED TODAY AHEAD OF AN APPROACHING CLOD FRONT. SOME THUNDERSTORMS COULD PRODUCE HEAVY DOWNPOURS LEADING TO LOCALIZED PONDING OF WATER IN POOR DRAINAGE AND LOW LYING AREAS. ANOTHER FRONTAL SYSTEM MOVING ACROSS THE REGION WILL BRING A CHANCE FOR SOME SHOWERS AND THUNDERSTORMS MONDAY AFTERNOON AND NIGHT.
