Severe thunderstorms produced damaging winds in parts of nothern Connecticut.
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 17, 2:57 PM EST, 3 hours 47 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 357 PM EDT SAT JUL 17 2010 .SYNOPSIS... HOT AND HUMID WEATHER WILL BE IN PLACE THROUGH THE REST OF WEEKEND WITH SCATTERED THUNDERSTORMS POSSIBLE THIS EVENING AND SUNDAY AFTERNOON. SOMEWHAT MORE WIDESPREAD TSTMS ARE POSSIBLE MONDAY AFTERNOON AND EVENING. OVERALL...MUCH OF THE FORECAST PERIOD WILL FEATURE MORE OF THE SAME WEATHER WE HAVE BEEN HAVING DURING JULY...VERY WARM AND HUMID. && .NEAR TERM /UNTIL 11 PM THIS EVENING/... ...RISK OF ISOLATED SEVERE TSTMS NORTHERN HALF OF AREA THIS EVENING... FORECAST CAPES OF 1000-1500 J/KG EXPECTED TO LINGER INTO THIS EVENING...AND THEN SLOWLY DIMINISH AFTER MIDNIGHT. CAPPING AROUND 12K FEET SHOULD LIMIT CONVECTIVE POTENTIAL UNTIL AROUND 6 PM...THEN MODEL SOUNDINGS SUGGEST GRADUAL EROSION OF CAP. BUFKIT SOUNDINGS FROM 12Z NAM CONSISTENT WITH MORE FAVORABLE INSTABILITY PARAMETERS SUCH AS SHOWALTER...K AND EVEN TOTAL TOTALS AS WELL AS COOLING ALOFT TO SUPPORT SCT TSTMS IN NW ZONES AFT 6 PM...SPREADING E THRU 11 PM. ALTHOUGH NH/MA LOOKS LIKE MOST FAVORED AREA...12Z NAM SUPPORTS DRAWING THE SCT EVENING TSTM AREA AS FAR S AS A BOS-BDL LINE. IN ADDITION...NOSE OF A 40 TO 45 KT MID LEVEL JET MAY BE ENOUGH TO ALLOW ONE OR TWO STORMS TO BECOME ORGANIZED ENOUGH TO BECOME SEVERE THIS EVENING. CONFIDENCE IS GROWING OF AN ISOLATED SEVERE RISK THIS EVENING BUT TEMPERED BY FACT THAT THE TIMING WILL BE AFTER THE SURFACE HEATING. CONVECTION OVER HIER TERRAIN OF SRN VT WEAKENING AS IT MOVES TO CT RIVER VALLEY. ADDITIONAL CONVECTION MOVING INTO E CENTRAL NY MAY PROVIDE THE STIMULUS NEEDED TO OVERCOME ANY REMAINING CAP EARLY THIS EVENING. && .SHORT TERM /11 PM THIS EVENING THROUGH SUNDAY NIGHT/... OVERNIGHT...MID LEVEL SHORTWAVE CONTINUES ACROSS SOUTHERN QUEBEC. AIR MASS IN E AND TOWARDS MORNING IN THE S UNSTABLE ENOUGH THAT A POP UP SHOWER OR TSTM POSSIBLE OVERNIGHT. PATCHY FOG EXPECTED AGAIN ALTHOUGH DEWPOINT MAY START TO DROP A LITTLE NW HALF OF AREA LATE TONIGHT. SUNDAY...ANOTHER HOT DAY BUT PROBABLY A FEW DEGREES COOLER THAN TODAY GIVEN SLIGHT 850 MB COOLING. ALSO...DEWPOINTS EXPECTED TO BE A FEW DEGREES LOWER NORTH OF A PYM-PVD-IJD LINE ON SUNDAY. WEAK SFC TROF AND SBCAPE VALUES 1500 TO 2000 J/KG MAY SUPPORT WIDELY SCT TO SCT TSTMS NE CT...RI AND SE MA SUNDAY AFTERNOON. WILL PUT IN CHC POPS IN MOST LIKELY REGION OF RI/SE MA. && .LONG TERM /MONDAY THROUGH SATURDAY/... VERY WARM AND HUMID DAY ON TAP FOR MUCH OF SNE ON MONDAY IN PRE-COLD FRONTAL AIRMASS. ENOUGH CONVERGENCE WILL DEVELOP IN ASSOCIATION WITH APPROACHING COLD FRONT AND/OR PREFRONTAL TROF MONDAY AFTERNOON TO TRIGGER AT LEAST WIDELY SCT THUNDERSTORMS IN AN ENVIRONMENT CHARACTERIZED BY MODERATE SBCAPE AND MODEST DEEP LAYER SHEAR. HAVE KEPT CHANCE POPS GOING...WITH HIGHEST VALUES MONDAY AFTERNOON INTO THE EVENING HOURS. INSTABILITY AND SHEAR PARAMETER WOULD BE SUPPORTIVE OF ISOLD SEVERE STORMS...WITH MAIN THREAT BEING WIND GIVEN EXPECTED STEEP BOUNDARY LAYER LAPSE RATES. SHORT WAVE TIMING WILL LIKELY DETERMINE AREAL COVERAGE. SLIGHTLY DRIER POST FRONTAL AIRMASS FOR TUESDAY...BUT STILL VERY WARM TO HOT. NO POPS AT THIS TIME. SOME MODEL GUIDANCE IS INDICATING THE POTENTIAL FOR AN MCS MOVING INTO NEW ENGLAND TUESDAY NIGHT. HOWEVER...OFTENTIMES THESE SYSTEMS ARE A FIGMENT OF THE MODELS IMAGINATION...AS CONVECTIVE FEEDBACK CAN ALLOW A MODEL TO HOLD ONTO A CONVECTIVE SYSTEM TOO LONG. FOR NOW...WILL ONLY GO WITH SLIGHT CHANCE POPS TUE NIGHT UNTIL WE SEE THE WHITES OF ITS EYES. WE THINK A SLIGHTLY BETTER CHANCE FOR CONVECTION MAY BE WEDNESDAY NIGHT WHEN SEEMINGLY BETTER SHORT WAVE SUPPORT ARRIVES. HOWEVER...MAINTAINED ONLY SLIGHT CHANCE POPS AT THIS TIME. THE GFS SEEMS TOO ROBUST WITH SFC LOW PRESSURE TRAVERSING ONTARIO AND QUEBEC FRIDAY AND FRIDAY NIGHT. WE DISCOUNTED THAT SOLUTION AND LEANED MORE TOWARD THE 12Z ECMWF. THIS MEANS WE KEPT POPS TO A MINIMUM UNTIL WE SEE INDICATIONS OF BETTER FORCING. OVERALL...WARMER THAN NORMAL TEMPERATURES ARE EXPECTED THROUGHOUT MUCH OF THE LONG TERM PERIOD WITH OCCASIONAL BOUTS OF SCT SHOWER/THUNDERSTORM ACTIVITY...BUT NO WASHOUTS. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... REST OF AFTERNOON...EXPECT VFR THROUGH THE AFTERNOON. A FEW WIND GUSTS SE MA 20 TO 25 KT FOR A TIME LATE THIS AFTERNOON. RISK OF TSTM DEVELOPMENT AFT 6 PM W OF A EEN-BAF LINE. TONIGHT...MEDIUM TO HIGH CONFIDENCE IN MAINLY VFR CONDITIONS. WIDELY SCT TO SCT TSTMS MAY BRIEFLY LOWER CIGS AND VSBYS THIS EVENING ALONG AND NORTH OF A BOS-BDL LINE. AN ISOLD TSTM OR TWO COULD ALSO PRODUCE SURFACE WIND GUSTS TO 40+ KNOTS THIS EVENING. PATCHY MVFR/IFR VALLEY FOG POSSIBLE LATE IN THE TYPICALLY PRONE LOCATIONS. KBOS...HIGH CONFIDENCE VFR THROUGH THE TAF PERIOD...EXCEPT A SLIGHT CHANCE OF BRIEFLY LOWER CONDITIONS IN VICINITY OF ANY TSTMS. ANY TSTMS MOST LIKELY WOULD OCCUR SOMETIME BETWEEN 01Z AND 04Z. SUNDAY...MEDIUM TO HIGH CONFIDENCE VFR. LOW PROB OF A FEW TSTMS DEVELOPING IN THE AFTERNOON ACROSS NE CT...RI AND SE MA. OUTLOOK...MONDAY THROUGH THURSDAY... FOR THE MOST PART...VFR CONDITIONS ARE EXPECTED THROUGH THE PERIOD AS A TYPICAL SUMMERTIME WEATHER PATTERN CONTINUES. AS IS USUALLY THE CASE IN SOUTHWESTERLY FLOW...THERE IS A CHANCE OF PATCHY FOG AND STRATUS AT NIGHT AND DURING THE MORNING HOURS THAT COULD LOWER CIGS/VSBYS FROM TIME TO TIME...ESPECIALLY ON THE SOUTH COAST. A CHANCE OF SHOWERS AND THUNDERSTORMS EXISTS MONDAY AFTERNOON. OVERALL...A HIGH CONFIDENCE FORECAST...BUT LOW CONFIDENCE IN KNOWING EXACTLY WHERE AND WHEN ANY STRATUS MAY OCCUR. && .MARINE... FORECASTING SEAS FOR OUTER S COAST WATERS A LITTLE PROBLEMATIC DUE TO PERSISTENT SW FLOW. LATEST TREND HAS BEEN FOR SEAS TO SUBSIDE SOME AND BELIEVE WAVE WATCH GUIDANCE IS RUNNING A FOOT OR SO TOO HIGH. NEVERTHELESS...MAY SEE SEAS APPROACH MARGINAL SCA CRITERIA WITH 5 FOOTERS AGAIN OUTER S COAST WATERS BY SUN NIGHT. FOR NOW...HOLDING OFF ON ANY HEADLINES...BUT WILL BE MONITORING TRENDS. OUTLOOK...MONDAY THROUGH THURSDAY... PERSISTENT SW FLOW WILL BRING SEAS TO SCA MARGINAL LEVELS ON THE SOUTH COASTAL WATERS. THESE SEA CONDITIONS SHOULD LINGER THROUGH WEDNESDAY OR THURSDAY. HOWEVER...WNAWAVE GUIDANCE MAY BE TOO ROBUST. APPROACHING COLD FRONT MONDAY AFTERNOON COULD BRING 20 TO 25 KNOT GUSTS TO THE NEAR SHORE WATERS. WINDS DIMINISH MONDAY NIGHT. EXCEPT FOR THIS...WINDS ARE EXPECTED TO REMAIN BELOW SCA LEVELS THROUGH PERIOD. && .BOX WATCHES/WARNINGS/ADVISORIES... CT...NONE. MA...NONE. NH...NONE. RI...NONE.
