The radar
The Albany radar (KENX), 115 km from the middle of the area, began a volume at 22:08 UTC, the scan nearest the moment this went out.
Open the radar archive at this moment
The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Albany, NY (KALY), launched 12:00Z, 10.1 hours before the alert went out and 108 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
600 PM EDT FRI JUN 28 2013
.SYNOPSIS...
WARM AND MUGGY CONDITIONS WILL CONTINUE WITH HIT AND MISS SHOWERS
AND THUNDERSTORMS THROUGH MUCH OF NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
*** FLASH FLOOD WATCH IS IN EFFECT THROUGH THIS EVENING. ***
SHOWERS AND THUNDERSTORMS HAVE REDEVELOPED ACROSS MUCH OF THE CWA.
THE SUN HAS BROKEN THROUGH A LOT OF THE AREA WITH THE EXCEPTION OF
SOUTHERN RHODE ISLAND AND FAR SOUTHEASTERN MASSACHUSETTS. THIS
HAS ALLOWED FOR ENOUGH HEATING THAT COUPLED WITH THE HIGH
DEWPOINTS /LOWER 70S/ QUITE A BIT OF SURFACE BASED INSTABILITY IS
BEING REALIZED ACROSS THE AREA. SPC MESOANALYSIS PAGE IS
INDICATING 1000 J/KG OF MIXED LAYER CAPE AT 3 PM. WHILE LOW CLOUDS
AND FOG ARE CURRENTLY ENTRENCHED ACROSS SOUTHERN RHODE ISLAND AND
SOUTHEASTERN MASSACHUSETTS...THE CLOUDS ON THE NORTHERN EDGES OF
THESE AREAS HAVE ERODED QUITE A BIT EVEN JUST OVER THE LAST HOUR.
THERE IS ALSO A DECENT AMOUNT OF SHEAR ACROSS THE AREA WITH A
STRONG LOW LEVEL JET IN PLACE. FINALLY...THE PWATS ARE FORECAST TO
REMAIN 1.5 TO 2 TIMES THAT OF NORMAL. ALL THAT SAID...THERE IS
POTENTIAL FOR A FEW STRONG TO SEVERE THUNDERSTORMS. HOWEVER...THE
MOST LIKELY THREAT WITH THESE STORMS IS HEAVY RAINFALL AND URBAN
FLOODING. STRONG TO DAMAGING WINDS AND HAIL ARE ALSO POSSIBLE.
TONIGHT...ANY CONVECTION THIS AFTERNOON SHOULD DWINDLE DOWN
THROUGH THE EVENING HOURS AS THE SUN GOES DOWN. HAVE KEPT CHANCE
POPS IN FOR SOME SCATTERED SHOWERS...AS MODELS ALL INDICATE SOME
QPF THROUGH THE NIGHT. OTHERWISE...ANOTHER WARM AND FOGGY NIGHT
EXPECTED WITH 70 DEGREE DEWPOINTS IN PLACE OVER THE AREA. MAY
WARRANT A DENSE FOG ADVISORY ACROSS SOUTHEAST MASS AND POSSIBLY
SOUTHERN RHODE ISLAND. AM NOT CONFIDENT THAT VISIBILITIES WILL
BE WIDESPREAD BELOW A QUARTER MILE SO WILL CONTINUE TO MONITOR.
EXPECT OVERNIGHT TEMPERATURES TO BE IN THE UPPER 60S TO LOW 70S.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
SATURDAY...A SHORTWAVE MOVES THROUGH THE UPPER LEVEL FLOW BRINGING
ANOTHER CHANCE OF SHOWERS AND THUNDERSTORMS SATURDAY AFTERNOON.
THERE IS A SIGNIFICANT AMOUNT OF SHEAR PARTICULARLY WHEN COMPARED
TO PREVIOUS DAYS. UPWARDS OF 40 KTS OF 0-6KM BULK SHEAR INDICATED
ON ALL THE MODELS. THE MID LEVEL LAPSE RATES ARE STILL FAIRLY
MODEST BUT PROVIDED THERE IS DECENT HEATING...THERE SHOULD BE
PLENTY OF INSTABILITY AROUND. THE PWATS ARE FORECAST TO BE A
LITTLE LOWER...BUT STILL WILL BE PLENTY HIGH...WITH 1.5 TO 1.75
INCHES OVER THE SOUTHEAST AND LOWER AMOUNTS TO THE NORTH AND
WEST...ALL STILL OVER AN INCH. FINALLY...SOUTHERN NEW ENGLAND IS
IN THE FAVORABLE RIGHT ENTRANCE REGION OF THE UPPER JET. WENT WITH
HIGH CHANCE POPS...THINKING MORE IN TERMS OF COVERAGE...WITH
SCATTERED SHOWERS AND THUNDERSTORMS. THE GREATEST THREAT REMAINS
THE HEAVY RAIN AND URBAN FLOODING...HOWEVER...THERE IS POTENTIAL
FOR STRONG TO POSSIBLY DAMAGING WINDS AS WELL AS HAIL WITH THESE
STORMS.
&&
.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
BIG PICTURE/PREFERENCES... MERIDIONAL FLOW THROUGH MIDWEEK WITH
RIDGES OVER THE WEST ATLANTIC AND WESTERN USA...TROUGHS/CLOSED LOWS
OVER THE GREAT LAKES-MISS RVR VALLEY AND EASTERN PACIFIC. THE GREAT
LAKES TROUGH BREAKS DOWN WEDNESDAY-THURSDAY AND EJECTS THROUGH NEW
ENGLAND TOWARD FRIDAY. THIS IS A PERSISTENCE PATTERN FOR MOST OF
THE LONG TERM...BUT HOLD OUT HOPE FOR CHANGES TOWARD THE END OF
THE WEEK. THE GFS AND ECMWF WERE SIMILAR IN THEIR MASS FIELDS...SO
WE USED A BLEND OF GFS/ECMWF GRIDS.
THE DAILIES...
SATURDAY NIGHT-SUNDAY... STALLED SURFACE FRONT IN THE VICINITY/UPPER
JET TO THE NORTHWEST BUT LINGERING/DIMINISHING LOW LEVEL JET
OFFSHORE POINTING TOWARD NOVA SCOTIA. PW/S REMAIN AT 1.5 TO 2.0
INCHES. SO CONTINUED CHANCE OF SHOWERS/DOWNPOURS WITH CLOUDS AND
DRIZZLE IN BETWEEN. HIGHEST POPS CAPE AND ISLANDS DIMINISHING
TOWARD THE NORTHWEST.
SUNDAY NIGHT-MONDAY... ANOTHER SHORTWAVE MOVES UP ACROSS THE REGION
WITH INCREASED LOW LEVEL JET AND TURNING OF THE LOW LEVEL WINDS TO
SOUTH. PW/S INCREASE TO AROUND 2 INCHES. THIS MEANS MORE LOW LEVEL
LIFT ON A JUICY AIRMASS. EXPECT SHOWERS/TSTMS WITH HEAVY DOWNPOURS
MOVING UP FROM THE SOUTH SUNDAY NIGHT AND CONTINUING MONDAY.
CONTINUE LIKELY POPS.
TUESDAY THROUGH FRIDAY... INGREDIENTS REMAIN IN PLACE THROUGH AT
LEAST THURSDAY...AND UPPER TROUGH SLIDES THROUGH ON FRIDAY. SO
EXPECT TO CONTINUE CHANCE POPS THROUGH THE PERIOD. GFS SHOWS
DIMINISHING PW VALUES FRIDAY NIGHT AND AFTER AS THE TROUGH MOVES
OFF. SO THERE IS POTENTIAL FOR THE CLOUDY/WET/HUMID PATTERN TO BREAK
BY THE END OF NEXT WEEK.
&&
.AVIATION /22Z FRIDAY THROUGH WEDNESDAY/...
FORECASTER CONFIDENCE LEVELS...
LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.
THROUGH 00Z...MODERATE CONFIDENCE. IFR CONDITIONS SOUTHEAST OF
INTERSTATE 95 EXPECTED TO CONTINUE IN LOW CLOUDS AND FOG. NORTH
AND WEST OF 95 HAVE A MIX OF CONDITIONS AS SHRA/TSRA DEVELOP AND
MOVE THROUGH THE AREA THIS AFTERNOON. EXPECT MAINLY VFR CONDITIONS
WITH BRIEF MVFR/IFR CONDITIONS IN ANY SHRA/TSRA THAT DEVELOP.
TONIGHT...HIGH CONFIDENCE IN TRENDS...MODERATE CONFIDENCE IN
TIMING. VFR/MVFR CONDITIONS WILL SLOWLY DETERIORATE TO MVFR/IFR
ACROSS THE REGION IN LOW CLOUDS AND FOG. LOWEST CONDITIONS WILL
LIKELY BE ALONG THE SOUTH COAST.
SATURDAY...MODERATE CONFIDENCE. SLOW IMPROVEMENT TO VFR THROUGH
THE MORNING. THEN MAINLY VFR. BRIEF MVFR/IFR CONDITIONS IN SCT
SHRA/TSRA DURING THE AFTN HOURS.
KBOS TERMINAL...MODERATE CONFIDENCE IN TAF. CONFIDENT IN OVERALL
TRENDS HOWEVER LOW CONFIDENCE IN TIMING...PARTICULARLY WITH
CONVECTION.
KBDL TERMINAL...MODERATE CONFIDENCE IN TAF. CONFIDENT IN OVERALL
TRENDS HOWEVER LOW CONFIDENCE IN TIMING...PARTICULARLY WITH
CONVECTION.
OUTLOOK...SATURDAY NIGHT THROUGH WEDNESDAY...
MODERATE CONFIDENCE.
NO CHANGES IN THE WEATHER PATTERN THROUGH MUCH OF THE UPCOMING WEEK.
THIS WILL MEAN SHOWERS AND SCATTERED TSTMS THROUGH AT LEAST
WEDNESDAY...SOME WITH HEAVY DOWNPOURS. THE DAYTIME MAY HAVE BASELINE
OF VFR...BUT WITH MVFR/IFR CIGS AND VSBYS IN ANY SHOWERS/TSTMS. THE
VERY HUMID AIRMASS LINGERS THROUGH THE PERIOD...SO NIGHT AND MORNING
FOG WILL BRING IFR/LIFR CIGS/VSBYS. THE LOW CLOUDS AND FOG MAY
LINGER DURING THE DAY ACROSS PARTS OF THE CAPE AND ISLANDS.
&&
.MARINE...
FORECASTER CONFIDENCE LEVELS...
LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.
THROUGH SATURDAY...HIGH CONFIDENCE...SCA CONTINUES ACROSS THE
WATERS. CONTINUED TO UNDERCUT WNA WAVE GUIDANCE BY ABOUT 10
PERCENT TO ACCOUNT FOR ITS SOUTHERLY BIAS. IN ADDITION...SOUTHERLY
WIND GUSTS TO 25 KTS ARE POSSIBLE ON THE NEAR SHORE WATERS
SATURDAY AFTERNOON. OTHERWISE...SHOWERS AND THUNDERSTORMS ARE
POSSIBLE ACROSS THE WATERS THROUGH SATURDAY. MAIN THREATS ARE LIGHTNING
AND HEAVY RAIN REDUCING VISIBILITIES.
OUTLOOK...SATURDAY NIGHT THROUGH WEDNESDAY...
MODERATE CONFIDENCE.
NO CHANGE IN THE WEATHER PATTERN THROUGH MUCH OF THE UPCOMING WEEK.
THIS WILL MEAN SHOWERS/TSTMS/FOG WITH VERY HUMID AIR. THERE WILL BE
POOR VSBYS AT TIMES...AND 1/4 MILE VSBYS IN FOG POSSIBLE EACH NIGHT
AND MORNING. SOUTH TO SOUTHWEST WINDS THROUGH THE PERIOD. WIND GUSTS
WILL BE 20 KNOTS OR LESS. BUT THE STEADY WIND DIRECTION WILL HELP
BUILD SEAS WITH WAVE HEIGHTS OF 5 TO 10 FEET EXPECTED ACROSS THE
OUTER COASTAL WATERS AND EXPOSED PORTIONS OF THE SOUTHERN SOUNDS
SUCH AS RI SOUND AND POSSIBLY BLOCK ISLAND SOUND. A SMALL CRAFT
ADVISORY WILL BE NEEDED FOR THESE ROUGH SEAS THROUGH
MIDWEEK...ESPECIALLY ACROSS THE OUTER COASTAL WATERS.
&&
.HYDROLOGY...
FLASH FLOOD WATCH CONTINUES THROUGH THIS EVENING. INSTANTANEOUS
RAINFALL RATES FROM THE RADAR HAVE BEEN ESTIMATED AT ABOUT 2
INCHES PER HOUR OVER THE PAST FEW HOURS. SO THE POTENTIAL FOR
HEAVY RAINFALL CONTINUES. WILL NEED TO KEEP AN EYE ON MAINLY
URBANIZED AREAS...WHERE CONVECTIVE HEAVY RAIN MAY LEAD TO URBAN
FLASH FLOODING.
