The episode as NWS ALY wrote it up.
A strong area of low pressure was situated over the Great Lakes region on Sunday, July 27th. An upper level shortwave, combined with an approaching warm front, allowed for a cluster of strong to severe thunderstorms to break out during the afternoon hours on July 27th over eastern New York, which spread into western Massachusetts during the late afternoon hours. In addition to straight-line wind damage and large hail, the area of thunderstorms also produced an EF1 tornado in Dalton, causing damage to trees and homes. Heavy rainfall from thunderstorms led to flash flooding, especially in the urbanized areas around Pittsfield.
As the strong area of low pressure moved across upstate New York on Monday, July 28th, some additional thunderstorms occurred during the afternoon hours. Trees were downed due to thunderstorms winds across parts of Berkshire County, as the storm's cold front moved through the area. With additional heavy rainfall occurring, flash flooding was renewed in some parts of the Berkshires once again, as two day rainfall totals were in excess of three inches in the Pittsfield area. Cooler and less humid air worked into the area behind the front for Monday night, ending the threat for severe weather and flooding.

NWS Albany, NY wrote its last area forecast discussion before the first event at Jul 27, 3:15 PM EST, 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 415 PM EDT SUN JUL 27 2014 .SYNOPSIS... LOW PRESSURE WILL ORGANIZE IN THE EASTERN GREAT LAKES TONIGHT AND TRACK NORTHEAST ACROSS NEW YORK. RAIN AND SCATTERED THUNDERSTORMS WILL OVERSPREAD THE REGION TONIGHT INTO MONDAY. THIS STORM WILL DEPART MONDAY NIGHT AND COOLER AIR WILL FILTER INTO THE REGION. MID WEEKS WEATHER WILL BE DOMINATED BY CANADIAN HIGH PRESSURE OVER THE GREAT PLAINS BUILDING SLOWLY EAST AND A LARGE DISTURBANCE ALOFT. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... ISOLATED CONVECTION EAST OF THE CAPITAL DISTRICT WILL HEAD INTO THE BERKSHIRES AND SOUTHERN VT AND WILL HAVE TO WATCH AN OUTFLOW BOUNDARY ON RADAR FROM NORTHERN SCHOHARIE THROUGH ALBANY COUNTIES FOR ANY NEW CONVECTION. THE RELATIVELY CLEAR SKY ACROSS THE REST OF THE REGION SUGGESTS SOME CAPPING DUE TO DRY AIR ALOFT...SO SUGGESTING JUST ISOLATED THUNDERSTORMS THROUGH THIS EVENING ACROSS AREAS OUTSIDE OF THE CURRENT STORMS. ANY THUNDERSTORMS THROUGH THIS EVENING COULD BE SEVERE...THEN AFTER MIDNIGHT...STRONG THUNDERSTORMS WITH STILL THE POSSIBILITY FOR MARGINAL SEVERE TRANSITIONING TO VERY HEAVY RAIN. WORDING SMALL HAIL...GUSTY WINDS AND HEAVY RAIN IN THE FORECAST. HOWEVER...QUITE A SPIN TO THE UPPER IMPULSE IN THE GREAT LAKES AND QUITE A BIT OF CONVECTION EXPANDING ACROSS THE GREAT LAKES AND OH/TN VALLEY. THERE HAS BEEN A DECENT CONSENSUS FROM GUIDANCE IN THE PAST COUPLE OF DAYS FOR UPPER DYNAMICS AND LOW LEVEL THERMAL AND JET FORCING TO SUPPORT STRONG CONVECTION TRACKING OUT OF THE NORTH MID ATLANTIC...NORTHEAST THROUGH THE CATSKILLS...MID HUDSON VALLEY...NORTHWEST CT AND THE BERKSHIRES...PERHAPS SCRAPING THE SCHOHARIE VALLEY...CAPITAL DISTRICT AND SOUTHERN VT. NIGHTTIME CONVECTION OFTEN WEAKER THAN DAYTIME CONVECTION BUT THE PREDICTED INSTABILITY...UPPER AND LOW LEVEL JET STRUCTURE AND UPPER DYNAMICS WITH A FAIRLY WELL DEFINED SURFACE LOW TRACKING THROUGH THE REGION...EARLY TO MID MORNING THUNDERSTORMS AGAIN COULD FLIRT WITH SEVERE LEVELS. WILL HAVE TO CHECK LIFTED CONDENSATION LEVELS AS STORMS APPROACH LATE TONIGHT AS THE LOW LEVEL SHEAR/HELICITY AND OTHER FORECAST MODEL CALCULATED SEVERE/TORNADO PARAMETERS ARE WORTH MONITORING WITH THE WELL DEFINED SURFACE/BOUNDARY LAYER LOW PRESSURE TRACKING THROUGH THE REGION. LOWS IN THE 60S TO NEAR 70. && .SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/... THE UPPER IMPULSE AND ASSOCIATED LOW LEVEL FORCING PIVOTS NORTH AND NORTHEAST THROUGH THE DAY...WITH STRONG CONVECTION TRANSITIONING TO SHOWERS WITH LOCALLY HEAVY RAIN AS THE COMMA HEAD PRECIPITATION TRAILS THE LEADING CONVECTION. KEEPING THE GUSTY WINDS AND HEAVY RAIN ASSOCIATED WITH CONVECTION TOMORROW...THEN COVERAGE OF RAIN SHOULD DECREASE THROUGH THE AFTERNOON...WITH THE SOUTHERN ADIRONDACKS...LAKE GEORGE SARATOGA REGION AND SOUTHERN VT TO THE NORTHERN BERKSHIRES SEEING THE RAIN END MORE TOWARD EVENING. HIGHS MONDAY IN THE 60S TO LOWER 70S...BUT COULD BE A LITTLE WARMER IF THERE ARE GAPS BETWEEN CLUSTERS OF SHOWERS AND THUNDERSTORMS. SOUTHERN AREAS COULD BE IN THE MID TO UPPER 70S DEPENDING ON HOW MUCH OF THE WARM SECTOR TRACKS THROUGH SOUTHERN AREAS THROUGH MIDDAY. WINDS ARE EXPECTED TO SHIFT TO WEST AND MAY BE GUSTY WHEN THE COLD FRONT TRACKS THROUGH DURING THE AFTERNOON AND EVENING. SOME GRADUAL CLEARING TAKES PLACE THROUGH THE NIGHT AND WINDS SHOULD DIMINISH. TUESDAY AND WEDNESDAY LOOK MAINLY DRY AS A COOLER AND DRYER AIRMASS SPREADS ACROSS THE REGION. THE MEAN UPPER TROUGH AXIS IS STILL A BIT WEST OF OUR REGION...SO THERE COULD BE SOME INTERVALS OF MID AND HIGH CLOUDS BUT AGAIN...THE WEATHER SHOULD BE DRY. HIGHS TUESDAY IN THE MID TO UPPER 70S...COOLER IN THE SOUTHERN ADIRONDACKS. ON WEDNESDAY...HIGHS IN THE UPPER 70S TO LOWER 80S...BUT LOWER TO MID 70S HIGHER ELEVATIONS. THE LEADING EDGE OF SOME SCATTERED SHOWERS COULD APPROACH WESTERN AREAS WEDNESDAY AFTERNOON WITH THE APPROACH OF ANOTHER UPPER IMPULSE. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... A MEAN LONGWAVE TROUGH WILL CONTINUE TO IMPACT THE NORTHEAST FROM THE MIDWEEK INTO NEXT WEEKEND. THE LONG TERM FORECAST WILL FEATURE SOME DISTURBANCES ROTATING THROUGH THE UPPER TROUGH UNTIL THE END OF WORK WEEK...BUT THEN HIGH PRESSURE OVER THE N-CNTRL ATLANTIC BUILDS WESTWARD WITH THE UPPER LEVEL FLOW BECOMING MORE SOUTHERLY LATE IN THE WEEKEND...AS A FRONTAL BOUNDARY REMAINS NEAR THE ATLANTIC SEABOARD FOR NEXT WEEKEND. WEDNESDAY NIGHT INTO THURSDAY...HIGH PRESSURE WILL BE RIDGING IN FROM THE OHIO VALLEY...AND THE MID ATLANTIC REGION. A SHORT-WAVE ROTATING AROUND THE UPPER LEVEL TROUGH MAY FOCUS SOME ISOLD-SCT SHOWERS LATE WED NIGHT...ESPECIALLY WEST OF THE HUDSON RIVER VALLEY. THE SFC TROUGH ASSOCIATED WITH THIS FEATURE MAY FOCUS SOME SCT SHOWERS AND ISOLD THUNDERSTORMS DURING THE AFTERNOON ON THU. THE GFS INDICATES MORE SYNOPTIC FORCING FROM THE DIFFERENTIAL CYCLONIC VORTICITY ADVECTION THAN THE ECMWF THIS RUN. THE BETTER FORCING LOOKS LIKE FROM THE CAPITAL REGION NORTHWARD...SO CHC POPS WERE USED HERE...WITH SLIGHT CHC FURTHER SOUTH. H850 TEMPS ARE STILL IN THE +8C TO +12C RANGE WITH LOWS IN THE 50S EXCEPT SOME U40S OVER THE SRN DACKS/ERN CATSKILLS/SRN GREENS...AND HIGHS ON THU IN THE U70S TO L80S IN THE VALLEYS...AND U60S TO M70S OVER THE HILLS AND MTNS. THURSDAY NIGHT INTO FRIDAY NIGHT...ANOTHER BRIEF BREAK IS EXPECTED WITH THE CLOSED LOW EMBEDDED IN THE HIGH AMPLITUDE LONGWAVE TROUGH OVER THE ERN CONUS DRIFTING N/NE TOWARDS JAMES BAY. WPC HAS WEAK SFC HIGH PRESSURE BUILDING IN OVER NY AND NEW ENGLAND THU NIGHT...THEN DRIFTING DOWNSTREAM. ANOTHER WEAK IMPULSE MAY TRIGGER SOME ISOLD SHOWERS/THUNDERSTORMS ON FRI...BUT WE KEPT IT AS A SLIGHT CHC IN THE GRIDS. THESE MAY BE TIED MORE TO THE DIURNAL HEATING OF THE DAY. EXPECT MAINLY DRY WEATHER THU AND FRI NIGHTS. LOWS WILL BE MAINLY IN THE 50S WITH PERHAPS A FEW READINGS CLOSE TO 60F FRI NIGHT IN THE CAPITAL DISTRICT AND MID HUDSON VALLEY. HIGHS FRIDAY WILL BE CLOSE TO NORMAL WITH WIDESPREAD U70S TO L80S OVER THE HILLS AND IN THE VALLEYS...WITH 70-75F READINGS COMMON OVER THE MTNS. SATURDAY INTO SUNDAY...DOWNSTREAM RIDGING OVER THE WESTERN ATLANTIC WILL BEGIN TO BUILD WESTWARD. THE MEAN UPPER-LEVEL TROUGH RETROGRADES SLIGHTLY UPSTREAM. WEAK DISTURBANCES IN THE S/SW FLOW ALOFT WILL FOCUS SCT SHOWERS AND THUNDERSTORMS ON SATURDAY AHEAD OF A WARM FRONT JUST EAST OF THE ATLANTIC SEABOARD. THE HUMIDITY WILL BE ON THE INCREASE...AS THE SFC FEW DEWPTS WILL BE RISING BACK INTO THE L60S WITH SOME MID 60S POSSIBLE. THE SHOWER COVERAGE MAY BE A BIT MORE WEST OF THE HUDSON RIVER VALLEY ON SUNDAY...OUR FCST REFLECTS CHC VALUES NORTH AND WEST OF THE CAPITAL DISTRICT WITH SLIGHT CHC VALUES TO THE SOUTH AND EAST. AN ISOLD THREAT OF THUNDERSTORMS WAS INCLUDED EVERYWHERE WITH THE INCREASE IN HUMIDITY AND SOME INSTABILITY. TEMPS WILL BE SEASONABLE FOR EARLY AUGUST. && .AVIATION /20Z SUNDAY THROUGH FRIDAY/... ISOLATED TO WIDELY SCATTERED SHRA/TSRA EXPECTED THIS AFTERNOON INTO THE EVENING AS A WEAK TROUGH MOVES THROUGH. DUE TO SPARSE COVERAGE...WILL ONLY MENTION VCSH IN THE TAFS. HOWEVER..A MORE WIDESPREAD AND ORGANIZED AREA OF RAIN WITH EMBEDDED THUNDERSTORMS SHOULD MOVE INTO THE REGION LATE TONIGHT INTO EARLY MONDAY MORNING...ASSOCIATED WITH A STRONG UPPER LEVEL DISTURBANCE AND RATHER INTENSE AREA OF LOW PRESSURE FOR THIS TIME OF YEAR. WILL MENTION PREVAILING RAIN AND MVFR WITH PROB30 FOR TSRA WITH IFR CONDITIONS. SOME OF THE STORMS MAY PRODUCE GUSTY WINDS AS WELL...ALTHOUGH THIS IS LESS CERTAIN. THE AREA THAT COULD SEE GUSTY TSRA WOULD BE MAINLY SOUTH OF KALB...INCLUDING THE KPOU/KPSF TERMINALS. WILL REFINE FORECAST FURTHER WITH SUBSEQUENT SET OF TAFS. WINDS TODAY WILL BE SOUTH-SOUTHWEST AROUND 5-10 KT...BECOMING VARIABLE TONIGHT INTO MONDAY AROUND 5-10 KT. OUTLOOK... MONDAY NIGHT: MODERATE OPERATIONAL IMPACT. SCATTERED SHRA. TUESDAY: NO OPERATIONAL IMPACT. NO SIG WX. TUESDAY NIGHT: NO OPERATIONAL IMPACT. NO SIG WX. WEDNESDAY: NO OPERATIONAL IMPACT. NO SIG WX. WEDNESDAY NIGHT: MODERATE OPERATIONAL IMPACT. NO SIG WX.

LOW PRESSURE WILL ORGANIZE IN THE EASTERN GREAT LAKES TONIGHT AND TRACK NORTHEAST ACROSS NEW YORK. RAIN AND SCATTERED THUNDERSTORMS WILL OVERSPREAD THE REGION TONIGHT INTO MONDAY. THIS STORM WILL DEPART MONDAY NIGHT AND COOLER AIR WILL FILTER INTO THE REGION. MID WEEKS WEATHER WILL BE DOMINATED BY CANADIAN HIGH PRESSURE OVER THE GREAT PLAINS BUILDING SLOWLY EAST AND A LARGE DISTURBANCE ALOFT. A RAINY PERIOD WITH STRONG THUNDERSTORMS IS EXPECTED THROUGH MONDAY. SO...RELATIVE HUMIDITIES ARE EXPECTED TO BE GREATER THAN 60 PERCENT THROUGH MONDAY NIGHT. HIGH PRESSURE AND DRYER WEATHER IS EXPECTED TO BUILD INTO THE REGION TUESDAY WITH RH VALUES DROPPING TO 40 TO 50 PERCENT. WINDS WILL BE VARIABLE AT 15 MPH OR LESS THROUGH TONIGHT.

A tree was downed and on power lines on Mountain Road in Lanesborough due to thunderstorm winds.
Trees were downed on Holmes Road in Pittsfield due to thunderstorm winds.
A National Weather Service Storm Survey determined that a microburst occurred in the Greenridge section of Dalton. Most of the direct damage from the microburst was to several hardwood and softwood trees, although one roof was partially lifted up on a house as a result of the wind as well. Newspaper media reported that at least twenty trees were downed in the area and power lines were downed as well. Minor damage to homes, mainly due to falling trees, occurred at least six residences. An EF1 tornado also occurred nearby, but the majority of the damage was attributed to the microburst.
A National Weather Service Storm Survey determined that an EF1 tornado occurred in the Greenridge section of Dalton. The tornado began in Greenridge park on South Street and moved southeast up a hill for one-quarter of a mile, before lifting behind residences on Lindsay Drive. The tornado downed a path of trees through a forest, clearing an area that was 10 to 20 yards wide.
A tree was downed in Hinsdale due to thunderstorm winds.
A large tree and wires were downed on Becket Road in Becket due to thunderstorm winds.

Heavy rainfall from thunderstorms heavily damaged a 1.5 mile stretch of the Berry Pond Circuit Road in the Pittsfield State Forest in Pittsfield. As a result of the flash flooding, 13 popular campsites at Berry Pond had to be closed for the remainder of the summer season due to the damaged access road. A local newspaper reported that when the flash flooding occurred, campers had to be evacuated before water cascading down the mountain gouged out the paved road. The damage to the road and eleven stone culverts was estimated to be significant and will cost between $173,000 and $277,000 to repair.
