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, 6:14 AM EST, 16 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
714 AM EDT THU SEP 8 2011
.SYNOPSIS...
SHOWERY WEATHER WILL CONTINUE INTO TONIGHT AS A FRONTAL BOUNDARY
LINGERS SOUTH OF NEW ENGLAND. HIGH PRESSURE WILL BUILD SOUTHEAST
FROM CANADA FRIDAY USHERING DRIER WEATHER. MEANWHILE KATIA WILL
TRACK SOUTHEAST OF NEW ENGLAND CONTINUING HIGH SURF AND SWELLS FOR
THE SHORELINES INTO FRIDAY. REMNANT LOW PRESSURE FROM ONCE TROPICAL
STORM WILL APPROACH SOUTHERN NEW ENGLAND THIS WEEKEND. THIS MAY YIELD
A FEW SHOWERS FOR THE AREA HOWEVER A WASHOUT IS NOT EXPECTED. THE
WEATHER THEME FOR EARLY NEXT WEEK FAVORS A WARMING TREND AHEAD OF
AN APPROACHING COLD FRONT THAT MAY YIELD SCATTERED SHOWERS TUE
AND/OR WED.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
7 AM UPDATE...
NOT MUCH CHANGE FROM PREVIOUS FORECAST AS WE CONTINUE TO EXPECT
PERIODS OF HEAVY RAIN AND EMBEDDED TSTMS THROUGH THE MORNING
BEFORE BECOMING MORE SHOWERY TOWARD MIDDAY. SATELLITE DERIVED
PRODUCTS CONTINUE TO INDICATE TROPICAL CONNECTION STREAMING UP THE
EASTERN SEABOARD WITH PWATS AOA 2 INCHES...WHICH IS ABOUT 200% OF
NORMAL! THIS ABUNDANT TROPICAL MOISTURE IS WORKING IN CONCERT WITH
STRONG LOW LEVEL FRONTOGENTICAL FORCING ASSOCIATED WITH A WARM
FRONT SOUTH OF NEW ENGLAND. GOOD MODEL AGREEMENT THAT THIS FRONTAL
BOUNDARY WEAKENS WITH TIME TODAY ALONG WITH UPPER LEVEL JET STREAK
EXITING NORTHERN NEW ENGLAND INTO THE MARITIMES. THUS HEAVY RAIN
WILL BECOME MORE SHOWERY TOWARD MIDDAY.
AREAL FLOOD ADVISORIES HAVE BEEN ISSUED FOR MUCH OF CT/WEST-
CENTRAL MA INTO SOUTHWEST NH AS WE EXPECTED MINOR FLOODING OF
SMALL RIVERS AND STREAM ALONG WITH POOR DRAINAGE FLOODING. IF THE
HEAVY RAIN PERSIST LONGER THAN EXPECTED THESE ADVISORIES WILL HAVE
TO BE UPGRADED TO WARNINGS. SO STAY TUNED TO LATER FORECASTS.
COOL TEMPS WILL CONTINUE GIVEN THE NE FLOW...OVERCAST CONDITIONS
AND RAIN.
&&
.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 AND SYNOPTIC OVERVIEW...
ABOVE AVERAGE FORECAST CONFIDENCE ON THE LARGE SCALE FLOW THIS
PERIOD AS BOTH THE 12Z/07 GEFS AND ECENS ARE TIGHTLY CLUSTERED.
HOWEVER CONFIDENCE IS BELOW AVERAGE ON THE SMALLER SCALE DETAILS.
BOTH MODELS AGREE THAT REMNANT MID LEVEL LOW FROM ONCE TS LEE WILL
REMAIN DETACHED FROM THE WESTERLIES THIS WEEKEND AND AS A RESULT
WILL MOVE SLOWLY FROM THE OH VLY TO NEW ENGLAND. WITH TIME THIS
CLOSED CIRCULATION WILL TRANSITION TO AN OPEN WAVE AND EJECT SHORT
WAVE IMPULSES AND MID LEVEL MOISTURE TOWARD SOUTHERN NEW ENGLAND.
HENCE PLAYING HAVOC WITH OUR WEEKEND FORECAST. THEN BY EARLY NEXT
WEEK GOOD MODEL AGREEMENT ON POLAR VORTEX SLIDING SOUTHWARD INTO
HUDSON BAY WHICH SERVES TO KICK BROAD NE MID LEVEL TROF FINALLY OFF
THE COAST. AHEAD OF THIS DEVELOPING HUDSON BAY TO GREAT LAKES MEAN
TROF WARM AIR ADVECTION PATTERN WILL SET UP OVER THE NORTHEAST
YIELDING A WARMING TREND HERE IN SOUTHERN NEW ENGLAND EARLY NEXT
WEEK.
DAILY DETAILS...
FRI NIGHT AND SAT...
BACKDOOR COLD FRONT SLIDES SOUTH FROM NORTHERN NEW ENGLAND FRI NIGHT
AND THEN ACROSS THE AREA SAT. MID LEVEL CONFLUENT FLOW THEN SETS UP
OVER THE AREA SAT PROVIDING LARGE SCALE MID LEVEL SUBSIDENCE AND
SURFACE HIGH PRES OVER THE REGION YIELDING DRY AND COOLER WEATHER.
THE 00Z GFS APPEARS TO BE AN OUTLIER WITH CONFLUENT ZONE FARTHER
NORTH ALLOWING LEFTOVER MOISTURE FROM REMNANT TS LEE OVER PA TO
STREAM EASTWARD INTO SOUTHERN NEW ENGLAND. GIVEN THE STRENGTH OF
THE NORTHERN STREAM JET PREFER THE SUPPRESSED SOLUTIONS FROM THE 00Z
NAM/GEFS AND ECMWF. THEREFORE HAVE UNDERCUT GFS MOS POPS BY
INCORPORATING THE DRIER METNAM POPS THIS PERIOD.
NE SURFACE FLOW AND SHALLOW COOL AIRMASS BEHIND BACKDOOR COLD FRONT
WILL YIELD LARGE TEMP DIFFERENCES SAT BETWEEN EASTERN MA /60S/ AND
THE CT RVR VLY /70S/.
SAT NIGHT THROUGH SUN NIGHT...
MID LEVEL CONFLUENT ZONE LIFTS NORTH PROMOTING FRONT TO OUR SOUTH TO
DRIFT NORTHWARD. UPSTREAM MID LEVEL LOW OVER THE OH VLY WILL
EJECT JET IMPULSES TOWARD THE REGION DURING THIS TIME FRAME. THE
COMBINATION OF THESE FEATURES WILL INCREASE THE RISK FOR SCATTERED
SHOWERS OVER SOUTHERN NEW ENGLAND. ALTHOUGH FORCING FOR ASCENT AND
INSTABILITY ARE MARGINAL SO AREAL COVERAGE OF SHOWERS WILL LIKELY BE
ISOLATED TO WIDELY SCATTERED. THUS TRIMMED GFS MOS POPS WITH DRIER
HPC GUIDANCE. OVERALL THE BULK OF THE WEEKEND APPEARS DRY WITH JUST
A LOW PROB OF DODGING A FEW SHOWERS...HIGHEST PROBS ACRS WRN MA INTO
CT AND COASTAL RI AND SOUTHEAST MA.
MON/TUE/WED...
REMNANT MID LEVEL LOW FROM ONCE TS LEE WILL FINALLY MOVE OFFSHORE MON
SUPPORTING A TREND TOWARD DRY WEATHER. NEW MEAN MID LEVEL TROF
DEVELOPS FROM HUDSON BAY SOUTHWARD TO THE GREAT LAKES TUE/WED. THIS
WILL LIKELY PROVIDE A WARMING TREND INTO THE NORTHEAST BEFORE A COLD
FRONTAL PASSAGE SOMETIME MIDDLE OF NEXT WEEK. THE RISK OF SHOWERS
WILL ALSO INCREASE WITH THIS FEATURE TUE AND WED. BEHIND THE FRONT
UNSEASONABLY COOL AIR MAY OVERSPREAD THE REGION.
