Several areas of low pressure traveled along a stationary front stalled across Southern New England producing showers and a few thunderstorms. In addition, strong southerly flow brought in a very moist airmass with precipitable water values above two inches.
Every event with a place to put it. Tap one for its entry below.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS BOX wrote it up.
Several areas of low pressure traveled along a stationary front stalled across Southern New England producing showers and a few thunderstorms. In addition, strong southerly flow brought in a very moist airmass with precipitable water values above two inches. This resulted in very heavy rain falling in these showers and thunderstorms. Many locations received up to two to three inches in less than an hour. This resulted in flash flooding, particularly in more urban areas.
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 Jul 28, 3:01 PM EST, 2 hours 27 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
401 PM EDT SAT JUL 28 2012
.SYNOPSIS...
LOW PRESSURE WILL MOVE ALONG A STALLED FRONT SOUTH OF NEW ENGLAND
TONIGHT AND SUNDAY. THIS WILL BRING SHOWERS AND SCATTERED
THUNDERSTORMS TO NEW ENGLAND THROUGH SUNDAY. AN ACTIVE PATTERN IS
EXPECTED INTO THE FOLLOWING WEEK...WITH DIURNALLY DRIVEN SHOWERS
AND THUNDERSTORMS MONDAY AND TUESDAY ACROSS THE INTERIOR...AND A
SERIES OF DISTURBANCES SWEEPING THROUGH THE REGION WEDNESDAY INTO
THURSDAY...AND AGAIN ON SATURDAY.
&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
UPPER SHORTWAVE TROUGH APPROACHING THROUGH NY AND PA WHILE RIGHT
ENTRANCE REGION OF SOUTHWEST UPPER JET PULLS OFF THROUGH THE
MARITIMES. DAYTIME HEATING PRODUCED 500 JOULES OVER THE INTERIOR
WHICH WAS TAPPED FOR AFTERNOON CONVECTION. THIS CONVECTION MOVED
INTO CENTRAL MASS WHERE IT RAN INTO THE EAST FLOW OFF
MASSACHUSETTS BAY.
THE UPPER JET WILL PROVIDE SUFFICIENT VENTING OF THE CONVECTION TO
KEEP IT GOING THROUGH THE EVENING. PRECIPITABLE WATER VALUES ARE
STILL HIGH...SO CONTINUE POTENTIAL FOR 2-4 INCHES OF RAIN IN THE
HEAVIEST DOWNPOURS. WITH SUNSET AND AS THE UPPER JET MOVES OFF
OVERNIGHT...THE POTENTIAL FOR STORMS WILL DIMINISH A LITTLE BUT
NOT COMPLETELY AS THE UPPER SHORTWAVE AND HUMID ATMOSPHERE WILL
CONTINUE TO SUPPORT CONVECTION.
EAST WINDS OFF MASSACHUSETTS BAY WILL PROVIDE A STABILIZING
INFLUENCE...SO LOWER POPS IN EASTERN MASS-RHODE ISLAND. SO POPS
WILL BE HIGHEST IN WESTERN SECTIONS AND LOWEST IN THE EAST.
CATEGORICAL POPS IN THE WEST THIS EVENING DIMINISHING TO LIKELY
POPS OVERNIGHT. CHANCE POPS IN THE EAST.
TEMPS ARE A BLEND OF MET AND MAV.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...
SUNDAY AND SUNDAY NIGHT...
UPPER SHORTWAVE MOVES ACROSS NEW ENGLAND DURING THE DAY AND OFF TO
THE EAST SUNDAY NIGHT. CONTINUE LIKELY POPS IN THE INTERIOR WITH
CHANCE POPS IN THE MORE STABLE EAST. CHANCE POPS SUNDAY EVENING
DIMINISH TO NIL DURING SUNDAY NIGHT. WEAK HIGH PRESSURE BUILDS
INTO THE REGION OVERNIGHT.
DEWPOINTS WILL DIMINISH A FEW DEGREES BUT STILL REMAIN IN THE 60S.
WITH LIGHT WIND AND A HISTORY OF RAIN...EXPECT AREAS OF FOG TO
DEVELOP SUNDAY NIGHT...SOME OF IT MAY BE DENSE.
TEMPS ARE A BLEND OF MOS.
&&
.LONG TERM /MONDAY THROUGH SATURDAY/...
MODEL DIAGNOSIS...
ANOMALOUS H5 RIDGING /POS HEIGHT ANOMALIES/ OVER THE CENTRAL NORTH
AMERICAN CONTINENT AND THE DAVIS STRAIGHT SETS THE PRECEDENT FOR
CONTINUED TROUGHING /NEG HEIGHT ANOMALIES/ ACROSS THE NERN CONUS.
DEEP CLOSED LOW ACROSS THE NRN CANADIAN MARITIMES WILL REMAIN QUASI-
STATIONARY TRAPPED BY A MARKED OMEGA BLOCK PATTERN ACROSS THE NRN
LATITUDES. WITH HEIGHT RISES OVER THE DAVIS STRAIGHT...SUBSEQUENT
RIDGING SHOULD CONTINUE ACROSS THE WRN ATLANTIC LENDING TO TROUGHING
AND AN ACTIVE WX PATTERN OVER THE NERN CONUS.
EVALUATING DETERMINISTIC SOLNS...WHILE MID-UPR LVL PATTERNS ARE
SOMEWHAT SIMILAR PER 28/12Z GFS AND 28/0Z ECMWF...HAVE GREATER
CONFIDENCE TO THE ECMWF SOLN WITH CONVECTIVE FEEDBACK ISSUES AND
SLIGHT MORE PROGRESSIVE NATURE WITHIN THE GFS SOLN. NOT ABSOLUTELY
SURE THE 28/12Z CANADIAN INITIALIZED WELL. WHILE THE GENERAL MID-UPR
LVL PATTERNS AGREE WITH OTHER DETERMINISTIC SOLN OUTCOMES...IT
REMAINS THE WEAKER OF THE THREE WITH LESSER PRECIP AMNTS.
MONDAY INTO TUESDAY...
DEPARTING SHRTWV VORT MAX THRU THE BROADER TROF LENDS TO WEAK
RIDGING AND SFC ANTICYCLONIC FLOW /WEAK HIGH PRES/ ACROSS THE GULF
OF ME. CONSIDERING PREVAILING S/SELY SFC FLOW AND A CONTINUED BROAD
TROF WITH CYCLONIC MOTIONS THRU THE MID-UPR LVLS...DIURNALLY DRIVEN
CONVECTION IS EXPECTED ACROSS INTERIOR NEW ENGLAND. NOT THINKING
SEVERE BUT HEAVY DOWNPOURS AND LOCALIZED FLOODING IS PSBL ESPECIALLY
FOR WRN AREAS WHICH WILL HAVE SEEN PRECEDING RAINS OVER THE WEEKEND.
MEANWHILE SELY ONSHORE FLOW WILL RESULT IN A MARITIME BOUNDARY LYR
REGIME ACROSS ERN AND CENTRAL NEW ENGLAND THEREBY LIMITING
CONVECTIVE POTENTIAL. OVRNGT PDS WILL BE QUIET...PSBLY PATCHY FOG
/ESPECIALLY FOR COASTAL AREAS/ WITH SFC DWPTS RANGING AROUND THE MID
60S.
WEDNESDAY INTO THURSDAY...
A PAIR OF DISTURBANCES WILL INVIGORATE A DEEPENING H5 TROF ACROSS
THE RGN WITH SFC LOW PRES DEVELOPMENT ACROSS THE DELMARVA PENINSULA
NEWD AND OFFSHORE OF NEW ENGLAND...WITH A WEAK SFC COLD FRNT SLIDING
SEWD OUT OF THE HUDSON BAY RGN OF CANADA. LOOKING AT A PROLONGED
PERIOD OF SHOWERS AND THUNDERSTORMS...THE TEMPORAL AND SPATIAL
SPECIFICS OF WHICH ARE UNCERTAIN. INITIAL ACTIVITY WED MAY PERTAIN
TO THE WRN INTERIOR OF THE NERN CONUS...GRADUALLY SHIFTING EWD
OVRNGT INTO THURS. ITS QUITE PSBL S/SELY FLOW AHEAD WILL ACT AS A
DETERRENT...FORCING STABLE MARITIME AIR ONSHORE AND KEEPING ACTIVITY
AT BAY. REMAINS TO BE SEEN WHETHER FLOODING WILL BE AN ISSUE...IT IS
PERHAPS WITH THE LOW PRES S OF NEW ENGLAND THAT THE BETTER SUB-
TROPICAL MOISTURE REMAINS ACROSS AND OFFSHORE OF THE MID-ATLANTIC.
FRIDAY...
A SYNOPTIC SITUATION SIMILAR TO MONDAY AND TUESDAY /ALBEIT SHORT/.
THOUGH WEAK HIGH PRES IN WAKE OF THE MID-WEEK SYNOPTIC DISTURBANCE
BROAD TROUGHING AND CYCLONIC FLOW PROVIDE FAVORABLE LIFT FOR
DIURNALLY DRIVEN ACTIVITY. BETTER CHCS WILL BE ACROSS THE WRN
INTERIOR OF NEW ENGLAND WITH ONSHORE S/SELY FLOW ADVECTING A MORE
STABLE MARITIME AIRMASS THEREBY LIMITING CONVECTIVE CHCS.
NEXT WEEKEND...
A SYNOPTIC DISTURBANCE WITH ATTENDANT COLD FRNT IS PSBL FOR
SATURDAY. SHOWERS AND THUNDERSTORMS WOULD BE LIKELY...AND PER THE
28/0Z ECMWF PSBLY SEVERE. WILL ONLY SPECULATE FOR NOW...LOT OF
UNCERTAINTY IN THE FCST. THE SYSTEM APPEARS PROGRESSIVE AS THERE ARE
INDICATIONS OF STRONG SHRTWV ENERGY DIGGING SWD OUT OF THE QUASI-
STATIONARY LOW OVER THE NRN MARITIMES. DRIER CONDITIONS WOULD FOLLOW
BRIEFLY FOR SUNDAY.
