The episode as NWS ALY wrote it up.
A cold front moved gradually southward across east central New York during the early morning hours of Monday, May 30th, while a disturbance in the upper levels of the atmosphere moved over the region. The frontal boundary and upper level disturbance provided the focus for a mesoscale convective system, an organized cluster of thunderstorms, to move across the mid Hudson Valley producing damaging winds.

NWS Albany, NY wrote its last area forecast discussion before the first event at May 30, 4:49 AM EST, 2 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 549 AM EDT MON MAY 30 2011 .SYNOPSIS... A DISTURBANCE MIGHT TRIGGER SOME EARLY MORNING SHOWERS AND STORMS. THEN,A RIDGE OF HIGH PRESSURE ALOFT WILL GRADUALLY BUILD THROUGH THE REMAINDER OF THE MEMORIAL DAY WEEKEND. IT WILL REMAIN VERY WARM. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... AS OF 530 AM...DECIDED TO INCREASE COVERAGE ONE MORE TIME FOR THE BROKEN LINE OF THUNDERSTORMS WORKING ACROSS OUR SOUTHERN AREAS. IN ADDITION...WE ADDED GUSTY WINDS AND HEAVY RAINFALL TO THE WORDING. MONTGOMERY IN ORANGE COUNTY RECEIVED 0.20 INCHES IN ABOUT 15 MINUTES TIME. THIS LINE LOOKS TO MOVE ACROSS MAINLY THE MID HUDSON VALLEY AND LITCHFIELD COUNTY...WITH LIGHTER SHOWERS AND THUNDERSTORMS TO THE NORTH AND TRAILING BEHIND THE INITIAL STORMS. THEY SHOULD CLEAR MOST PLACES BY 800 AM. WILL KEEP MONITORING. SO FAR...NO WARNINGS ISSUED BY THIS OFFICE...BUT A SPECIAL WEATHER STATEMENT DESCRIBING THE POTENTIALLY STRONG STORMS. ****PREVIOUS NEAR TERM... AS OF 430 AM...THE ORIGINAL MCV HAS WEAKENED BUT A SECONDARY MCS DEVELOPED ON THE SOUTHWEST FLANK OF THE ORIGINAL DISTURBANCE. THIS SYSTEM HAS TURNED MOVED TO THE EAST AND AS GETTING CLOSE TO OUR SOUTHWESTERN ZONES. SHORT TERM MODELS HAVE INSISTED THIS SECONDARY DISTURBANCE WILL WEAKEN AS IT HEADS INTO AREA. IT HAS WEAKENED SLIGHTLY BUT WILL LIKELY IMPACT AREAS TO THE SW OF ALBANY. THESE THUNDERSTORMS COULD CONTAIN HEAVY RAINFALL. THE CLOUD TO GROUND LIGHTNING STRIKES SPIKED ABOUT AN HOUR AGO...BUT HAVE SLOWLY DECREASED. ONE PINHEAD SHOWER HAS ALSO POPPED UP IN BERKSHIRE COUNTY. WILL BE MONITORING THIS ON GOING CONVECTION AND WILL MAKE FURTHER ADJUSTMENTS ON THE GRIDS AS NECESSARY. WE DID BUMP COVERAGE TO NUMEROUS TO THE SOUTH OF ALBANY THROUGH ABOUT 800 AM. THROUGH 800 AM...LOOK FOR SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS ACROSS THE REGION WORKING INTO AREAS MAINLY SOUTH OF THE CAPITAL REGION. TEMPERATURES THIS MORNING ARE EVEN WARMER THAN LAST NIGHT. ANY SHOWER ACTIVITY WOULD KNOCK TEMPERATURES BACK INTO THE UPPER 60S...BUT NOT MUCH COOLER THAN THAT. THIS DISTURBANCE LOOKS TO MOVE ON BY AFTER 8 AM ALONG WITH ANY SHOWER AND THUNDERSTORM ACTIVITY SO HOPEFULLY NOT TOO MANY HOLIDAY PARADES WILL BE IMPACTED. THE DEPARTING MCV WILL ACTUALLY TURN OUR WIND TO THE NORTHWEST AND ALLOW A SURFACE HIGH TO BRIEFLY BUILD DOWN FROM EASTERN CANADA TODAY. THE AIR ASSOCIATED WITH HIGH PRESSURE IS ONLY SLIGHTLY COOLER THAN THE AIR AHEAD AS H850 TEMPS ONLY ARE GOING TO COOL A DEGREE OR TWO AT MOST (STILL AROUND +16C). AT THE SAME TIME...SUBSIDENCE NEAR THE SURFACE AND DOWNSLOPING WINDS OFF THE DACKS/CATSKILLS WILL BREAK UP THE CLOUDS BY AFTERNOON ALLOWING STRONG SUNSHINE. THE SUN IN TURN WILL WARM THE LOWER LEVELS AND TEMPERATURES SHOULD WARM TO THEIR HIGHEST READINGS OF THE YEAR. WILL STILL EXPECT TEMPS TO TOP OUT AROUND 90 DEGREES TO THE LEE OF THE CATSKILLS/UPPER 80S IN THE CAPITAL DISTRICT...80-85 MOST OTHER PLACES. DEWPOINTS LOOK TO DROP A LITTLE DOWN THROUGH THE 60S TODAY AND EVEN 50S NORTH AND WEST OF THE CAPITAL DISTRICT. WITH SUCH A SETUP THERE IS VERY LITTLE THREAT OF ANY RENEWED THUNDERSTORM ACTIVITY SO THE BALANCE OF THIS HOLIDAY WILL BE DRY. && .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/... FINALLY...IT LOOKS AS IF WE SHOULD HAVE A COMPLETELY CONVECTION FREE NIGHT (WHICH HAS BEEN VERY RARE OF LATE). SURFACE HIGH PRESSURE WILL CREST AT THE SURFACE...WHILE HIGH PRESSURE ALOFT WILL BE BUILDING OVERHEAD. WITH A CLEAR SKY AND LIGHT OR NO WIND...TEMPERATURES WILL ACTUALLY COOL A BIT MORE THAN PREVIOUS NIGHTS. WE LOOK FOR LOW TEMPS DOWN TO AROUND 60 IN THE CAPITAL DISTRICT...LOWER 60S SOUTH...50S MOST OTHER PLACES. A FEW OF THE SHELTERED MOUNTAIN VALLEYS OF ESPECIALLY THE DACKS COULD ACTUALLY TOUCH THE UPPER 40S! WENT WITH A MET/MAV BLEND. FOR TUESDAY...SURFACE HIGH PRESSURE MOVES OFFSHORE AND THE UPPER HIGH PRESSURE CRESTS OVER THE REGION. H850 TEMPS WILL WARM BACK UP TO AROUND +17C. THE WIND WILL TURN TO THE SOUTH. HOWEVER...SINCE WE WILL START OFF WITH COOLER TEMPS...HIGH TEMPERATURES WERE TRIMMED BACK A COUPLE OF DEGREES FROM BEFORE. THE DAY LOOKS DRY AS WE REMAINED CAPPED WITH A WARM LAYER IN THE MID LEVELS. LOOK FOR HIGH TEMPERATURES TO TOP OUT NEAR 90 DEGREES IN THE MID HUDSON VALLEY AND LOWER LITCHFIELD COUNTY...MID TO UPPER 80S THE REMAINDER OF THE HUDSON VALLEY...80-85 HIGHER TERRAIN. DEWPOINTS WILL START OUT IN THE 50S...BUT TREND TOWARD 60 OR HIGHER MOST PLACES BY DAY/E END. TUESDAY NIGHT...A COLD FRONT WILL BEGIN TO SLIP SOUTH FROM CANADA INCREASING CONVECTIVE THREATS AGAIN. PWAT VALUES REMAIN ABOUT 1.5 INCHES. HOWEVER...SURFACE CONVERGENCE LOOKS WEAK AS DO THE WINDS ALOFT...THE JET STAYING TO THE NORTH OF THE REGION. ALSO...IT APPEARS THAT THE COLD FRONT WILL MOVE ACROSS THE REGION DURING NIGHTTIME. WITH A SOUTHERLY FLOW AND INCREASING CLOUDS/DEWPOINTS ACTUALLY WENT A LITTLE HIGHER FOR OVERNIGHTS LOWS THAN ALL GUIDANCE...GENERALLY IN THE 65-70 RANGE FROM ALBANY SOUTHWARD...UPPER 50S TO MID 60S FURTHER NORTH. WITH A SOUTHERLY FLOW AND INCREASING CLOUDS/DEWPOINTS ACTUALLY WENT A LITTLE HIGHER FOR OVERNIGHTS LOWS THAN ALL GUIDANCE...GENERALLY IN THE 65-70 RANGE FROM ALBANY SOUTHWARD...UPPER 50S TO MID 60S FURTHER NORTH. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... FOR A CHANGE...THE EXTENDED PERIOD LOOKS FAIRLY "QUIET" WITH A GRADUAL RETURN TO NEAR NORMAL TEMPERATURES AND MAINLY DRY WEATHER. THE COLD FRONT (OR FRONTS) WILL LIKELY BE TO OUR SOUTHEAST WEDNESDAY NIGHT. A FRESH BREEZE OUT OF THE NORTHWEST WILL BRING COOLER AIR DOWN FROM CANADA. THERE IS STILL SOME UNCERTAINTY HOW COOL THIS AIR WILL BE. THE ECMWF STILL BRINGS AIR AS COOL AS +2C AT THE H850 LEVEL AS FAR SOUTH AS THE MOHAWK VALLEY. THE GFS HAS NOW TRENDED WARMER...WITH THE AIR ONLY COOLING TO ABOUT +8C. WE FEEL THE +2C FORECAST FOR THE H850 TEMPS MIGHT BE A BIT OVERDONE BY THE ECMWF BUT THE GFS MIGHT BE A BIT WARMER. WENT FOR A COMPROMISE BETWEEN THE TWO. THURSDAY WILL BE A BREEZY DAY WITH EXCELLENT MIXING LIKELY FROM WELL ABOVE THE H850 LEVEL SO DESPITE ON GOING COLD AIR ADVECTION...TEMPERATURES LOOK TO REACH WELL INTO THE 80S IN THE MID HUDSON VALLEY...NEAR 80 IN THE CAPITAL DISTRICT...70S FURTHER NORTH...EXCEPT HOLDING IN THE 60S ACROSS THE HIGHER PEAKS OF THE DACKS. THERE COULD BE A FEW LIGHT SHOWERS OR SPRINKLES IN THE DACKS BUT FOR NOW...NOT HAVE INCLUDED THEM. OTHERWISE...THERE SHOULD BE MORE SUNSHINE THAN CLOUDS. THURSDAY NIGHT LOOKS TO TURN ALMOST CHILLY IN OUR PARTS. TEMPERATURES LOOK TO DROP WELL DOWN INTO THE 40S WELL NORTH OF ALBANY...50-55 ALBANY SOUTHWARD. WE STILL EXPECT A BREEZE OR OTHERWISE THESE READINGS WOULD BE EVEN COOLER. THE SKY WILL BE MAINLY CLEAR. A PARTLY TO MOSTLY SUNNY DAY FRIDAY WITH TEMPERATURES TOPPING OUT A LITTLE BELOW NORMAL...WITH HIGHS ONLY IN THE 60S NORTH AND WEST OF ALBANY...AROUND 70-75 HUDSON VALLEY AREAS AS THE SURFACE HIGH IS FORECAST TO BUILD OVERHEAD. HIGH PRESSURE WILL THEN MOVE SOUTH AND EAST AND A RETURN FLOW WILL BEGIN A WARMUP AS WE HEAD INTO THE WEEKEND. HOWEVER...BEFORE IT GETS TOO UNCOMFORTABLY WARM OR HUMID...ANOTHER COLD FRONT FROM CANADA LOOKS TO SLIP DOWN ON SUNDAY. CHANCES OF SHOWERS LOOKS LOW FROM THIS VANTAGE POINT BUT WE DID INCLUDE SLIGHT CHANCES LATER SATURDAY THROUGH SUNDAY SINCE THE TIMING IS NOT UNCERTAIN. BY WEDNESDAY EVENING...THE COLD FRONT SHOULD BE CROSSING THE EASTERN ZONES OF THE CWA. WILL KEEP A SLIGHT CHC FOR SHRA/TSRA FOR EASTERN AREAS THROUGH THE LATE EVENING HOURS...BUT WILL DROP POPS FOR ALL AREAS AFTER MIDNIGHT. MIN TEMPS ON WED NIGHT WILL GENERALLY BE IN THE 50S...WITH UPPER 40S IN THE HIGH TERRAIN. TEMPS ON THURSDAY WILL BE SOMEWHAT COOLER THAN WEDNESDAY...AS A LESS HUMID CANADIAN AIR MASS BUILDS INTO THE REGION. HOWEVER...THE MODELS NOW DISAGREE ON JUST HOW MUCH OF A COOL DOWN OCCURS...AS SOUTHERN AREAS MAY STILL CONTINUE TO STAY FAIRLY WARM. WILL DROP TEMPS A LITTLE BIT FOR THURSDAY...BUT MOST VALLEY AREAS FROM GLENS FALLS SOUTH STILL APPEAR TO REACH AT LEAST 80...WITH MID 80S FOR THE MID HUDSON VALLEY. && .AVIATION /10Z MONDAY THROUGH FRIDAY/... CONVECTIVE COMPLEX JUST ENTERING THE WESTERN PART OF THE ALY FORECAST AREA. IT HAS WEAKENED CONSIDERABLY AND IT NOW APPEARS UNLIKELY TO AFFECT THE KGFL/KALB/KPOU TAF SITES IN ANY SIGNIFICANT WAY. HAVE GENERALLY FORECAST VFR CONDITIONS AT ALL THREE TAF SITES THROUGH THE TAF PERIOD ENDING AT 06Z TUESDAY. THE EXCEPTIONS ARE A TEMPO GROUP WITH MVFR CONDITIONS AT KGFL/KALB BETWEEN 07Z AND 08Z IN CASE THE CONVECTION SYSTEM REACHES THESE TWO TAF SITES. AT KPOU HAVE FORECAST A TEMPO GROUP FOR POSSIBLE MVFR FOG THROUGH 11Z...THEN A ONE HOUR TEMPO GROUP BETWEEN 11Z AND 12Z WITH MVFR CONDITIONS FOR SHOWERS ASSOCIATED WITH THE BACK SIDE OF THE CONVECTIVE COMPLEX. AT ALL THREE LOCATIONS HAVE FORECAST ANY PCPN WITH JUST SHRA AND INCLUDED CB IN THE CLOUD GROUP. NOT CONFIDENT ENOUGH AT THIS TIME TO FORECAST TSRA. SURFACE WINDS WILL BE CALM OR LIGHT SOUTH (UNDER10 KTS) THROUGH A LITTLE AFTER SUNRISE. THEN BECOME NORTHWEST AT 6 TO 10 KTS FOR THE REST OF THE DAY...THEN BECOME LIGHT AFTER SUNSET MONDAY EVENING. OUTLOOK... LATE MON NT-TUE...MAINLY VFR. NO SIG WX. CHANCE FOG LATE MONDAY NITE. WED...VFR...CHC MVFR WITH SCT SHRA/TSRA. THU-FRI...VFR. BREEZY W-NW WINDS. && .FIRE WEATHER... THUNDERSTORMS WILL MOVE ACROSS MAINLY THE AREA JUST SOUTH OF ALBANY THIS MORNING BUT WILL BE GONE BEFORE MIDDAY. AFTER THAT...SUNSHINE AND DRYING CONDITIONS WILL RETURN. RH VALUES LOOK TO DROP TO AROUND 35-45 PERCENT BY AFTERNOON AS A NORTH OR NORTHWEST BREEZE PICKS UP IN THE 5-15 MPH RANGE. RELATIVE HUMIDITIES WILL INCREASE TO 80-90 PERCENT TONIGHT...BUT WITH THE WIND BECOMING LIGHT OR CALM WE THINK SOME DEW WILL FORM. RH VALUES LOOK FALL BACK TO AROUND 40 PERCENT BY TUESDAY AFTERNOON AS THE WIND TURNS BACK TO THE SOUTH 5-15 MPH AND TEMPERATURES WARM QUITE A BIT AGAIN. A COLD FRONT MIGHT BRING WIDELY SCATTERED SHOWERS OR THUNDERSTORMS TUESDAY NIGHT OR WEDNESDAY. AFTER THAT...WE LOOK FOR AN EXTENDED DRY PERIOD WEDNESDAY NIGHT THROUGH AT LEAST SATURDAY MORNING. IT MIGHT TURN QUITE BREEZY ON BOTH BY THURSDAY. && .HYDROLOGY... THUNDERSTORMS THIS MORNING MIGHT BRING LOCALIZED DOWNPOURS TO OUR SOUTHERN AREAS WITH SOME PLACES RECEIVING A QUARTER TO THREE QUARTERS OF AN INCH THROUGH MID MORNING. HOWEVER...SUCH RAINFALL SHOULD BE OVER A SMALL AND NOT EXPECTED TO IMPACT LARGE STEM RIVERS. OF COURSE SUCH RAIN COULD PRODUCE LOCALIZED PONDING OF POOR DRAINAGE AREA AND QUICK RISES ON SMALL CREEKS. THE REMAINDER OF THE HOLIDAY LOOKS DRY. THE NEXT CHANCE OF SHOWERS OR THUNDERSTORMS WILL BE TUESDAY NIGHT INTO WEDNESDAY BUT THE CHANCES LOOK SLIM AT THIS POINT. AFTER THAT...AN EXTENDED PERIOD OF DRY WEATHER MIGHT BE IN THE OFFING INTO THE WEEKEND.
