The episode as NWS BOX wrote it up.
A slow moving cold front moved across Southern New England and stalled just south of the area. This front was instrumental in bringing tropical moisture from the remnants of Tropical Storm Lee into New England. A series of shortwaves moved through the northeast during this time period bringing several periods of showers and steady rainfall to parts of Southern New England. Rainfall totals throughout the region over the four days totaled anywhere from two to eight inches, with most areas receiving four to six inches. This resulted in flooding both on the rivers and small streams and in urban areas. The bulk of the flooding in urban areas occurred on Sept. 8 as a band of very heavy rain moved through, dumping up to two inches of rain in an hour to hour and a half in some locations.
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 Boston/Norton, MA wrote its last area forecast discussion before the first event at Sep 8, 3:04 AM EST, 21 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
404 AM EDT THU SEP 8 2011
.SYNOPSIS...
SHOWERY WEATHER WILL CONTINUE ALONG AND NORTH OF A LINGERING
FRONTAL BOUNDARY SOUTH OF NEW ENGLAND. INTO TONIGHT HIGH PRESSURE
WILL BUILD SOUTHEAST OUT OF CANADA USHERING DRIER WEATHER.
MEANWHILE KATIA WILL TRACK SOUTHEAST OF NEW ENGLAND CONTINUING
HIGH SURF AND SWELLS FOR THE SHORELINES. INTO FRIDAY LINGERING
REMNANTS OF LEE MAY BRING SCATTERED WET WEATHER CONTINUING INTO
SATURDAY. HIGH PRESSURE WILL BUILD DOWN THE COAST FROM NORTHERN
NEW ENGLAND SUNDAY...THEN ANCHOR OFF THE COAST EARLY NEXT WEEK
WITH DRY AND COOLER WEATHER.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
FOR THIS MORNING...LINE OF MODEST RAINS WITH EMBEDDED HEAVIER
THUNDERSTORMS WILL PROGRESS NWD WITH THE RGN OF BEST ISENTROPIC
ASCENT AND FRONTOGENETICAL FORCING OF THE WARM MOIST TROPICAL
CONVEYOR BELT ALONG AND N OF THE SFC FRNTL BOUNDARY S OF NEW
ENGLAND. THE DEEP LYR MOIST CONVERGENCE WILL YIELD PRECIP ACCUM
AVERAGES OF AROUND HALF TO ONE WHOLE INCH IN A VERY SHORT PERIOD OF
TIME.
THIS STILL POSES CONCERNS FOR SOME VERY SWOLLEN SMALL STREAM AND
TRIBUTARIES...ESPECIALLY WITHIN THE SMALL BASINS THAT DRAIN INTO THE
MAINSTEM CONNECTICUT RIVER. FLOOD WARNINGS EXIST FOR THE MAINSTEM
CONNECTICUT FROM MONTAGUE CITY S INTO MIDDLETOWN...WITH A FLOOD
WATCH INTO MIDDAY FOR SURROUNDING VICINITIES. AT PRESENT SMALL
STREAMS ARE REMAINING WITHIN THEIR BANKS...BUT LIKELY THE ABUNDANCE
OF RAIN UPON ALREADY SATURATED GROUND FROM PERSISTENT RAINS OVER THE
PAST 48 HRS WILL YIELD URBAN AND POOR DRAINAGE FLOODING.
OTHERWISE FOR TODAY...SHOULD SEE THE BIFURCATION OF SHRTWV ENERGY AS
A RIDGE OF HIGH PRES BUILDS OUT OF THE CENTRAL PLAINS CONJOINING
WITH THE ATLANTIC RIDGE. THIS WILL PRESS THE MID-LVL TROF EWD AND
THRU THE ERN CANADIAN MARTIMES. AS THE REMNANTS OF LEE DISCONNECT
FROM THE MEAN FLOW...WAVERING WWD INTO THE LOWER OH RVR VLY RGN...
THE UPR LVL SUPPORT AND ISENTROPIC ASCENT OF THE WARM MOIST CONVEYOR
BELT SUSPENDS. STILL AN ABUNDANCE OF LLVL MOIST TROPICAL AIR WELL IN
PLACE WITH SOME REMNANT WEAK ISENTROPIC LIFT WITHIN THE VICINITY OF
A STALLED FRNTL BOUNDARY JUST S OF NEW ENGLAND WILL RESULT IN A
DREARY...COOL...AND CLAMMY DAY WITH SHOWERS AND PERSISTENT DRIZZLE.
WILL KEEP CHC TO LIKELY POPS...REDUCING INTO DUSK AS DRIER AIR AT
MID-LVLS BEGINS TO WRAP CYCLONICALLY INTO S NEW ENGLAND AHEAD OF
KATIA/S APPROACH.
REMAINING MOSTLY CLOUDS...PERHAPS MIXING UP TO H925 WHERE TEMPS
HOWEVER +16-18C...WILL KEEP THE DAY COOL WITH MAX TEMPS IN THE MID TO
UPR 60S THRU MUCH OF THE INTERIOR WITH PERHAPS LOW 70S ALONG THE S
SHORELINE AND CT VLY RGN. LIGHT E/NELY WINDS.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
THURSDAY NIGHT...
AS KATIA SLIDES SE OF NEW ENGLAND AND BEGINS ITS NE TRACK OUT TO
SEA...RIDGE OF HIGH PRES WILL BE IN CONTROL...AND MID-LVL DRY AIR
CONTINUES TO WRAP CYCLONICALLY ALONG THE N PERIPHERY OF KATIA
ITSELF. ISENTROPIC FLOW BACKS OUT OF THE N...EXHIBITING A
DOWNWELLING TREND IN RESPONSE TO KATIA. LIGHT NLY SFC FLOW CONTINUES
WITH SLIGHTLY COOLER AND DRIER AIR SETTLING INTO THE RGN. CLOUDS
STILL IN CONTROL...PERHAPS A FEW BREAKS ALONG THE S SHORELINE WITH
THE INTRUSION OF DRIER AIR. MINS IN THE UPR 50S TO LOW 60S N TO S.
FRIDAY...
DRIER AIR AND RIDGE OF HIGH PRES IN PLACE. KATIA SLIDES NEWD PAST
NEW ENGLAND AND MAY SEE GUSTS UP TO 30 MPH OVER NANTUCKET WITH THE
POTENTIAL OF SOME OUTER BAND INTERACTION WITH SHOWERY WX. THE
REMAINDER OF THE RGN MAY GRADUALLY CLEAR OUT MIDDAY INTO AFTN. YET
THIS IS SHORT LIVED AS THE ATLANTIC RIDGE BUILDS WWD WITH KATIA/S
DEPARTURE...ENHANCING THE MID-UPR LVL CYCLONIC FLOW AROUND THE
REMNANTS OF LEE OVER THE LWR OH RVR VLY RGN. THE COLLOCATION OF THE
LEFT EXIT RGN OF THE MID-UPR LVL JET STREAK WILL LEND FOR SHOWERS
AND POTENTIAL THUNDERSTORMS TOWARDS THE END OF THE PD FOR THE WRN
FCST RGN. CONFIDENCE IS LOW AT THIS TIME...SOME DEPENDENCY LIES ON
MOISTURE AVAILABILITY. WITH POTENTIAL CLEARING CONDITIONS AND H925
TEMPS OF +18-20C...COULD SEE UPR 70S TO LOW 80S FOR MAX TEMPS.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
MODEL PREFERENCES...
THIS AFTERNOON/S MODEL SUITE IS PRETTY CLOSE WITH THEIR TRACKS OF
TRACK AND MOVEMENT OF HURRICANE KATIA ON FRIDAY...ESPECIALLY THE 12Z
OP GFS AND ECMWF RUNS. STILL EXPECTING KATIA TO PASS WELL SE OF
NANTUCKET FRIDAY...THEN RACE OFF TO THE OPEN NORTH ATLANTIC. BEYOND
THIS...MODELS IN FAIR AGREEMENT IN HANDLING THE DECAYING REMNANTS OF
TROPICAL STORM LEE...WHICH MAY BRING PATCHY SHOWERS ACROSS CENTRAL
AND SOUTHERN AREAS EARLY THIS WEEKEND. TIMING OF THE BREAK OFF OF
PIECES FROM THIS REMNANT LOW AND TRACKING IS STILL SOMEWHAT IN
QUESTION. HOWEVER...SHOULD EVENTUALLY DISSIPATE...PROBABLY LATER
THIS WEEKEND. EXPECT SOME BROAD TROUGHING ACROSS THE GREAT LAKES AND
CENTRAL CANADA LATER THIS WEEKEND INTO THE LATTER PORTIONS OF THIS
PERIOD. FOR THE MOST PART...LOOKS LIKE MAINLY DRY TO COOLER
CONDITIONS LATE THIS WEEKEND INTO EARLY NEXT WEEK.
DAILY DETAILS...
FRIDAY...
EXPECT HURRICANE KATIA TO PASS WELL SE OF NANTUCKET SOMETIME FRIDAY
MORNING TO MIDDAY...THEN WILL ACCELERATE NE. MAIN IMPACTS WILL
CONTINUE TO BE DANGEROUS SEAS AND HEAVY SURGE ALONG WITH SOME WINDS
/CHANCE OF NE WIND GUSTS TO 30-35 MPH/ AROUND NANTUCKET AND THE
OUTER CAPE. SUBSIDENCE TO THE NW OF KATIA/S CIRCULATION SHOULD KEEP
DRY CONDITIONS AND PARTLY TO MOSTLY SUNNY SKIES FOR THE REMAINDER OF
THE REGION.
MAY START TO SEE MORE CLOUDS WORK IN ACROSS W MA/N CENTRAL CT DURING
THE AFTERNOON AHEAD OF NEXT APPROACHING SYSTEM WORKING OUT OF THE
OHIO VALLEY. OTHERWISE...SHOULD BE A PLEASANT DAY. EVEN WITH SOME
CLOUDS AROUND...WARMING AT H85 TO AROUND 15C-16C SHOULD ALLOW TEMPS
TO RISE TO THE MID 70S TO AROUND 80.
FRIDAY NIGHT AND SATURDAY...
MODELS STILL HAVE SOME CONSISTENCY ISSUES IN BRINGING A PIECE OF
REMNANT ENERGY FROM THE LEFTOVERS OF FORMER TROPICAL STORM LEE OUT
OF THE OHIO VALLEY. LOOKS LIKE THIS SHOULD PASS EITHER ALONG THE S
COAST OR FURTHER OFFSHORE. HOWEVER...SHOULD STILL SEE ENOUGH LIFT
AND MOISTURE TO PUSH CLOUDS AND SCT SHOWERS ACROSS CENTRAL AND
SOUTHERN AREAS...MAINLY NEAR AND S OF THE MASS PIKE DURING THIS
TIMEFRAME. A DRY COLD FRONT WILL ALSO WORK S OUT OF NORTHERN NEW
ENGLAND...WHICH WILL HELP PUSH THIS ENERGY OFFSHORE FROM MIDDAY TO
LATE AFTERNOON ON SATURDAY.
LARGE HIGH PRES STARTS TO BUILD DOWN THE COAST LATER SATURDAY AND
SATURDAY NIGHT. NOTING A RATHER STRONG PRESSURE SURGE AND INCREASING
NE WINDS BEHIND THE DRY COLD FRONT. WINDS MAY BECOME RATHER GUSTY
ALONG THE COAST SATURDAY NIGHT.
SUNDAY...
12Z GFS AND ECMWF WERE IN PRETTY GOOD AGREEMENT IN PUSHING THE HIGH
OUT OF NORTHERN NEW ENGLAND ACROSS THE REGION DURING THIS TIMEFRAME.
GUSTY NE WINDS WILL CONTINUE THROUGH A GOOD PORTION OF THE DAY...
MAINLY S OF BOSTON TO THE S COAST...CAPE COD AND THE ISLANDS. EXPECT
A MOSTLY SUNNY DAY FOR MOST AREAS. HOWEVER...WITH THE E-NE WINDS...
MAY START TO SEE MORE CLOUDS WORK IN AS THE HIGH SETTLES OFF THE
COAST.
MONDAY THROUGH WEDNESDAY...
NOT A WHOLE LOT OF CONFIDENCE WITH THIS PORTION OF THE FORECAST DUE
TO MODEL RUN INCONSISTENCIES...BUT FOR NOW HAVE CARRIED A DRY BUT
COOL FORECAST AS HIGH PRES REMAINS ANCHORED WELL E AND SE OF NEW
ENGLAND. BIG QUESTION REMAINS THE LEFTOVER ENERGY THAT STILL SITS
ACROSS PA/NJ FROM THE REMNANTS OF TS LEE. CLOUDS MAY LINGER THROUGH
A PART OF MONDAY WITH THE ONSHORE FLOW. ANOTHER FRONT MAY START TO
APPROACH OUT OF QUEBEC BY MID WEEK.

ALL OF THIS WITH PERIODS OF 13-15 SECONDS AND SWELLS OF 10 TO 12
FEET.
WITH REGARDS TO WINDS...WILL SEE E/NE FLOW INCREASE THURSDAY NIGHT
INTO FRIDAY...WITH THE STRONGEST GUSTS FRIDAY MORNING INTO MIDDAY
WITH GUSTS OF UPWARDS OF 30 KTS.
THE BUILDING SEAS AND LONG PERIODS WILL RESULT IN HEAVY SURF ALONG
PORTIONS OF THE COASTLINE EXPOSED TO SOUTHEAST SWELL. HIGH SURF
AND SMALL CRAFT ADVISORIES HAVE BEEN EXTENDED ACCORDINGLY.
OUTLOOK...SATURDAY THROUGH MONDAY...
SATURDAY-SUNDAY...EXPECT WINDS TO SHIFT TO NE AS HIGH PRES BUILDS S
ACROSS THE WATERS. AS THE HIGH BUILDS DOWN...WILL SEE PRES SURGE
WORKING ACROSS THE WATERS FROM N-S. WILL LIKELY SEE WIND GUSTS TO 25
KT ON THE OPEN EASTERN WATERS DURING SAT...WORKING INTO THE SOUTHERN
OPEN WATERS SAT NIGHT-SUN. SEAS WILL BUILD TO 5-6 FT MAINLY ACROSS
