The episode as NWS ALY wrote it up.
A very warm and humid air mass was in place over western Massachusetts during the day on Sunday, May 29th. Although strong upper level ridging was initially in place over the area, an upper level trough started to approach from the west, with a surface cold front moving towards the area from Canada.
During the afternoon hours, bands of slow moving showers and thunderstorms broke out over the Berkshires and slowly moved northeast. Due to the slow movement of these thunderstorms, heavy rainfall repeatedly fell over the same area in the Lee and Stockbridge portions of Berkshire County. This resulted in flash flooding occurring across the area, as some roads were temporarily closed due to being covered by water and debris. The flooding was so significant in Stockbridge that town officials declared a state of emergency. Spotters measured up to five inches of rainfall falling in just a few hours.
In addition, the thunderstorms produced gusty winds. This downed some trees and power lines across the area as well.
With the loss of daytime heating, showers and thunderstorms ended by the evening hours and the weather was quiet into the overnight hours. This allowed water to quickly recede across the region.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Albany, NY wrote its last area forecast discussion before the first event at May 29, 12:34 PM EST, 1 hour 1 minute earlier.
Area Forecast Discussion National Weather Service Albany NY 134 PM EDT SUN MAY 29 2016 .SYNOPSIS... Another day of hot and humid weather today. The high pressure system which has been in place across the region will weaken over the rest of the weekend and a low pressure system will approach and cross the area bringing showers and thunderstorms especially this afternoon and tonight. Some storms will produce heavy downpours. && .NEAR TERM /THROUGH TONIGHT/... Convection continues to fire up across area in moist unstable airmass in place across region. Dew points are in the mid/upper 60s and SPC mesoscale analysis indicates surface based CAPE values are ranging from around 1000 to about 3000 j/kg. Precipitable water values are high with 1.25 inches on the 12Z/ALY morning sounding. These values are forecast to rise to around 1.5 inches this afternoon so some storms will produce heavy downpours. With upper ridge across region flow is light and storms are moving slowly northeastward. Have already issued a small stream flood advisory for a portion of northwestern Albany County into east central Schoharie County for convection caught on the terrain/Helderbergs. Have focused likely pops across the southern Adirondacks, Mohawk Valley into the Schoharie Valley where the greater coverage is expected and ran with mainly scattered convection for the rest of the forecast area. Added enhanced heavy rainfall wording for the thunderstorms into this evening. Low clouds from the Connecticut River Valley eastward across New England continue to gradually rise but are being very stubborn to break up. Have adjusted temperatures especially in this area where they are only in the 60s and 70s due to the clouds. The high will lose its grip on the region tonight; heights will fall as a upper level trough approaches. The focus for the greatest chances/coverage for rainfall will shift to the area mainly south and east of the Capital District as the precipitable water values rise to about 2 inches as tropical and Atlantic moisture are drawn northward into our region. Have enhanced wording for locally heavy rainfall for this area overnight. Expecting mainly showers with isolated thunderstorms possible through the overnight. Another muggy night with lows only dripping back into the 60s with high dew points and light winds. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... Monday will also be fairly active as multiple frontal boundaries are expected to cross the area. Monday morning may be more active than Monday afternoon as the axis of high PWATS slides east of the forecast area by Monday afternoon. Still expect fairly widespread shower and thunderstorm activity. MLMUCAPES are generally down to 500 to 1000 J/KG by late in the day on Monday. Highs are expected to be in the mid 70s to lower 80s. On Monday night conditions are expected to improve with any lingering convection weakening during the evening with dry weather expected during the second half of the night. Lows Monday night are expected to be in the mid 50s to lower 60s. Tuesday and Tuesday night will feature dry weather and more seasonable conditions as a ridge of high pressure builds into the northeast from the Tennessee and Ohio valley regions. Expect highs on Tuesday to be in the mid 70s to mid 80s with the lows Tuesday night to be in the 50s. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... Tranquil conditions for the start of the long term portion of the forecast, Wednesday-Thursday, as a ridge of high pressure extends across the region from eastern Canada. This ridge will eventually slide off the New England coast later Thursday, as an upper level trough and attendant cold/occluded front approaches from the Great Lakes region for Thursday night-Friday. This front may slow down and potentially stall just south and east of the region by Saturday. So, expect dry conditions for Wednesday into Thursday, with mainly sunny/clear skies. Temperatures should be slightly above seasonal levels, with highs reaching the mid 70s to lower 80s, and overnight low temperatures mainly in the 50s, except for some 40s across portions of the southern Adirondacks and southern Vermont. Clouds should increase late Thursday, and more so for Thursday night into Friday. As the front moves across Friday and Friday night, expect some showers or a period of rain. Chance POPS are indicated at this time range, since there is some uncertainty as to how widespread the areal extent of showers or rain will be. Have kept chance POPS into Saturday for most of the region outside of the western Adirondacks, as the front possibly slows its east/southeast progress, and potentially stalls. With the expectation for clouds and some showers, have indicated cooler high temperatures for Friday-Saturday, with mid 60s to lower 70s, warmest in valley locations. Overnight low temperatures should mainly be in the 50s, although may not fall much below 50 in some portions of the immediate Hudson River valley. && .AVIATION /17Z SUNDAY THROUGH THURSDAY/... As an upper level trough begins to approach...some scattered showers and thunderstorms have developed north and west of KALB/KGFL. These thunderstorms will slowly move east and affect KALB and KGFL roughly between 21Z-23Z but will be amended if movement changes or if new thunderstorms develop closer to the sites. MVFR ceilings and visibilities are possible in thunderstorms...with some variable winds and gusts to perhaps 25 kt. A few thunderstorms are south of KPSF and slowly building north and east and may just miss KPSF...but close enough so that VCTS included this afternoon and as long as the storms build slowly north...there could be a period of thunderstorms between 21Z-23Z with MVFR ceilings and visibilities. All the thunderstorms are quite a distance from KPOU...so keeping rain out of KPOU until later tonight...when mostly showers and a possible isolated thunderstorm...after 06Z. After about 00Z...larger area of showers and scattered thunderstorms will gradually track through the region...affecting KGFL...KALB and KPSF. So...indicating VCTS through about 02Z-03Z with periods of MVFR visibilities and ceilings in thunderstorms. Periods of showers and MVFR ceilings and visibilities are possible through 13Z-15Z at KGFL...KALB and KPSF. Showers will linger at KPOU through 18Z. Winds will be variable and gusty up to 25 kt in thunderstorms through this evening. OUtside of thunderstorms...winds will be south at up to 10 kt this afternoon. South to southeast winds should decrease to less than 10 KT after sunset and continue light to near calm through the night. Winds should become south to southwest at 6 kt or less after 14Z-15Z Monday morning. Outlook... Monday Night: No Operational Impact. NO SIG WX. Tuesday: No Operational Impact. NO SIG WX. Tuesday Night: No Operational Impact. NO SIG WX. Wednesday: No Operational Impact. NO SIG WX. Wednesday Night: No Operational Impact. NO SIG WX. Thursday: No Operational Impact. NO SIG WX. && .FIRE WEATHER... It will be another day of hot and humid weather today. The high pressure system which has been in place across the region will weaken over the rest of the weekend and a low pressure system will approach and cross the area bringing showers and thunderstorms especially this afternoon and tonight. Some storms will be capable of producing heavy downpours. Relative humidity values are expected to drop to 45 to 60 percent this afternoon...recover to 80 to 100 percent tonight...and drop to 55 to 75 percent on Monday. Winds are expected to be south at 5 to 10 mph today...light and variable tonight...and southwest at 5 to 10 mph on Monday. && .HYDROLOGY... The high pressure system which has been in place across the region will weaken over the rest of the weekend and a low pressure system will approach and cross the area bringing showers and thunderstorms especially this afternoon and tonight. Some storms will be capable of producing heavy downpours. Precipitable water values will be high through the remainder of the weekend especially Sunday night into Monday when they are expected to be 1.5 to approaching 2 inches; 175 percent of normal as tropical moisture is drawn into the region. Thus heavy downpours are expected with some storms. Widespread hydrologic issues are not anticipated, however heavy downpours are expected which would lead to ponding of water and minor flooding of urban, poor drainage, and low lying areas. Drier weather looks to take hold for the middle of next week as high pressure builds in. Chances for rain will return late in the week into the weekend as a low pressure system approaches.
