NWS Boston/Norton, MA wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 3, 10:12 PM EDT, 16 minutes earlier.
Area forecast discussion, Aug 3, 10:12 PM EDT, 16 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 1012 PM EDT FRI AUG 3 2007 .SYNOPSIS... A COLD FRONT EXITING THE GREAT LAKES WILL SWEEP ACROSS NEW ENGLAND TONIGHT AND SATURDAY...WITH SCATTERED THUNDERSTORMS ALONG AND AHEAD OF IT. HIGH PRESSURE THEN BRINGS DRY AND LESS HUMID WEATHER ACROSS THE REGION SUNDAY. THE HIGH WILL PUSH OFFSHORE SUNDAY NIGHT ALLOWING A WARM FRONT TO CROSS SOUTHERN NEW ENGLAND MONDAY AND MONDAY NIGHT. WARMER AND MORE HUMID AIR WILL THEN MOVE BACK ACROSS SOUTHERN NEW ENGLAND TUE. A COLD FRONT WILL APPROACH THE REGION LATE TUESDAY AND WEDNESDAY...TRIGGERING THUNDERSTORMS. THE FRONT WILL MOVE OFFSHORE WEDNESDAY NIGHT FOLLOWED BY DRIER AND COOLER AIR THURSDAY AND FRIDAY. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... ***A FEW SEVERE THUNDERSTORMS THIS EVENING NORTHWEST OF I-95 WITH THE BEST CHANCE ACROSS CENTRAL MASS WITH STORMS POSSIBLY REDEVELOPING OVERNIGHT SEWD INTO CT AND NRN RI** YOURE SEEING THE STORMS WARNINGS AND LOCAL STORM REPORTS. WEAK SFC LOW AS SEEN VIA MSAS STILL NR ALY AND ITS DERIVED ACTIVITY ROLLING TWD ORH IS SVR...A SUPERCELL. SO THE ATMOSPHERE CONTS POTENT AND WHILE WE EXPECT DIMINISHMENT DURING THE NIGHT... ITS NOT GOING TO BE ENTIRELY QUIET. DAMAGING STORMS ARE ANTICIPATED THROUGH ABOUT 11 PM...AND WELL NEED TO BE ALERT OVERNIGHT. S WIND TO 29 KTS AT AMBROSE STIL AT 01Z TOGETHER WITH POT TEMP AND INSTABILITY AXIS IS PROBABLY GOING TO RESULT IN RAPID NEW DEVELOPMENT ARD SOON NEAR MASS PIKE WHEREVER THE OUTFLOW BOUNDARY STOPS. OVERNIGHT HOURS WE MAINTAIN FAIRLY STEEP MID LEVEL LAPSE RATES OF AROUND 7C/KM WITH 500 MB TEMPERATURES AROUND -11C. THIS RESULTS IN AROUND 1000 J/KG OF SURFACE BASED CAPE ALL NIGHT LONG AND SHOWALTER INDICES -2 AND -3. THEREFORE...ALTHOUGH WE DONT HAVE A STRONG LOW LEVEL JET WEAK BOUNDARY IN THE VICINITY SHOULD ALLOW FOR SCATTERED THUNDERSTORMS THROUGH THE NIGHT. WE PROBABLY WILL SEE THE AXIS OF THE BEST CHANCE FOR CONVECTION SHIFT TO THE COASTAL PLAIN BY AROUND 12Z. WILL RUN WITH CHANCE POPS ACROSS THE ENTIRE REGION OVERNIGHT. ANY THUNDERSTORMS WILL BE CAPABLE OF PRODUCING LOCALLY HEAVY RAINFALL WITH HIGH PWATS ALL NIGHT. LOW TEMPERATURES WILL REMAIN QUITE MILD WITH READINGS IN THE UPPER 60S TO LOWER 70S. IN FACT...DOWNTOWN BOSTON MAY NOT FALL BELOW 73 OR 74 DEGREES ALL NIGHT. WE WILL LIKELY SEE PATCHY FOG LATE AND IT PROBABLY WILL BE DENSE AGAIN ON NANTUCKET. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/... A MOSTLY SUNNY AND BEAUTIFUL DAY IS ON TAP TO THE NORTHWEST OF I-95. SOUTHEAST OF I-95...ANY ELEVATED SHOWERS/THUNDERSTORMS WILL PROBABLY DIMINISH BY MID MORNING. HOWEVER...THE FRONTAL BOUNDARY WILL BE HUNG UP ACROSS RHODE ISLAND AND SOUTHEAST MA. THEREFORE...WE PROBABLY WILL SEE ISOLATED TO SCATTERED THUNDERSTORMS RE-DEVELOP ACROSS RHODE ISLAND AND SOUTHEAST MA IN THE AFTERNOON. WIND FIELDS ARE A BIT STRONGER THAN TODAY AND LAPSE RATES WILL BE FAIRLY STEEP BETWEEN 6.5 AND 7.0C/KM. THEREFORE...A FEW SEVERE THUNDERSTORMS WILL BE POSSIBLE IN THIS REGION. THE MAIN THREATS WILL BE DAMAGING STRAIGHT LINE WIND GUSTS AND LARGE HAIL. HIGH TEMPERATURES SHOULD TOP OUT IN THE UPPER 80S TO NEAR 90 NORTH OF MASSACHUSETTS TURNPIKE...WITH READINGS IN THE LOWER 90S SOUTH OF THE MA PIKE AND AWAY FROM THE SOUTH COAST. IN ADDITION...WITH SOUTHWEST WINDS WE EXPECT A MODERATE RISK FOR RIP CURRENTS ALONG THE SOUTH FACING BEACHES OF THE SOUTH COAST ON FRIDAY. && .LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/... SATURDAY NIGHT... COLD FRONT WILL BE DRAPED ACROSS THE SOUTH COAST SATURDAY EVENING...ALONG WITH THE CHANCE OF SHOWERS AND THUNDERSTORMS ACROSS SOUTHEAST MA AND SOUTHERN RI. ONE OR TWO STORMS MAY BE CAPABLE OF PRODUCING HAIL AND GUSTY WINDS BEFORE THE FRONT MOVES OFFSHORE. BY LATE EVENING...FRONT SHOULD BE PUSHING OFFSHORE WITH DRY AND MUCH LESS HUMID WEATHER OVERSPREADING THE ENTIRE REGION. LOOKS LIKE ONE OF THE FEW COMFORTABLE NIGHTS WITH DEW PTS IN THE 50S AND MINS BY SATURDAY MORNING IN THE 50S AND 60S. SUNDAY... LOOKS LIKE A GEM OF A DAY AS DEEP LAYER RIDGE MOVES OVER NEW ENGLAND PROVIDING ABUNDANT SUNSHINE...DEW PTS IN THE 50S AND AFTERNOON TEMPS IN THE UPPER 70S TO LOW 80S. IN FACT...SURFACE DEW PTS MAY DIP INTO THE UPPER 40S INLAND...AS MODEL SOUNDINGS FROM BOTH THE GFS AND NAM INDICATE GOOD MIXING TO 4-5 KFT YIELDING DRY AIR MIXING FROM TOP DOWN...RATHER THAN HORIZONTAL ADVECTION. SUN NIGHT AND MONDAY... NEXT SHORT WAVE TROF AND ASSOCIATED SURFACE LOW EXIT THE GREAT LAKES AND INTO NORTHERN NEW ENGLAND. THE NAM APPEARED TO BE AN OUTLIER HERE WITH ITS OVER AMPLIFIED AND FASTER SOLUTION WHEN COMPARED TO THE GFS AND UKMET. THEREFORE...THIS PORTION OF THE FORECAST WAS BASED ON 12Z GFS AND UKMET. A WARM FRONT WILL MOVE ACROSS THE REGION MON...WHICH WILL RESULT IN THE CHANCE OF SHOWERS REGION WIDE...WITH THE HIGHEST CHANCE ACROSS NORTHERN MA INTO NH. THE WARM FRONT EXITS THE AREA SOMETIME MON NIGHT OR EARLY TUE...SO THE CHANCE OF SHOWERS WILL LIKELY CONTINUE INTO MON NIGHT. IT WILL BE COOLER MON GIVEN ONSHORE FLOW...OVERCAST SKIES AND POSSIBLE SHOWERS. HOWEVER...DEW PTS WILL BE ON THE INCREASE GIVEN THE ONSHORE FLOW. TUESDAY THROUGH FRIDAY... OVERALL THEME HERE IS FOR VERY WARM AND HUMID CONDITIONS TUE AND WED WITH A COLD FRONTAL PASSAGE /BACKDOOR/ SOMETIME WED-WED NIGHT...FOLLOWED BY COOLER TEMPS AND LESS HUMID WEATHER THU AND POSSIBLY INTO FRI. THE TRICKY PART OF THE FORECAST WILL BE THE LOCATION OF THE COLD FRONT TUE AND WED AND RELATED POP FORECAST. 12Z GFS APPEARS TO HAVE TOO MANY WAVES ALONG THIS FRONT WHICH MAY BE A CONVECTIVE FEEDBACK PROBLEM. THE 12Z ECMWF HAS LESS IF ANY CONVECTIVE FEEDBACK ISSUES...SO THE HIGHER CHANCE OF SHOWERS AND TSTMS APPEARS TO BE WED /PER THE 12Z ECMWF/ WITH LESS OF A THREAT TUE. BACKDOOR FRONT MOVES ACROSS THE AREA SOMETIME WED NIGHT WITH COOLER AND MUCH LESS HUMID WEATHER THU AND FRI. TEMPS MAY REMAIN IN THE 70S REGION WIDE THU /EXCEPT AROUND 80 CT RIVER VALLEY/...THEN PROBABLY WARMING INTO THE LOW 80S INLAND FRI...AS HIGH PRES MOVES OFFSHORE. && .AVIATION /02Z SATURDAY THROUGH WEDNESDAY/...

VFR CONDITIONS ARE EXPECTED THROUGH THE EVENING...BUT ISOLATED TO SCATTERED CONVECTION ACROSS THE INTERIOR MAY BRIEFLY RESULT IN MVFR/IFR CONDITIONS. OTHERWISE...A FEW HOURS OF MVFR CONDITIONS MAY DEVELOP LATE IN PATCHY FOG. IN ADDITION...IFR CONDITIONS WILL LIKELY DEVELOP ACROSS NANTUCKET THIS EVENING AND POSSIBLY MAKE THEIR WAY ONTO HYANNIS. ON SATURDAY...VFR CONDITIONS SHOULD DEVELOP BY EARLY TO MID MORNING. HOWEVER...ISOLATED TO SCATTERED CONVECTION ACROSS RHODE ISLAND AND SOUTHEAST MA MAY RESULT IN BRIEF MVFR/IFR CONDITIONS.

THEN VFR CONDITIONS OVERNIGHT SAT NIGHT INTO SUN AND POSSIBLY SUN NIGHT. MVFR CEILINGS MON AND MON NIGHT AS WARM FRONT AND SHOWERS MOVES ACROSS THE AREA. LOW PROB OF IFR CONDITIONS IF DENSE FOG FORMS MON-MON NIGHT AHEAD OF WARM FRONT. CONDITIONS SHOULD IMPROVE TUE AS WARM FRONT EXITS THE AREA. HOWEVER...MVFR CONDITIONS POSSIBLE TUE AFTERNOON AND NIGHT IN TSTMS AS NEXT COLD FRONT APPROACHES.

IN THE LONGER TERM...EXPECT CONDITIONS TO REMAIN BELOW SCA SUNDAY AND MONDAY INTO TUESDAY. FOG PATCHES MAY LOCALLY REDUCE VISIBILITIES UNDER 1 MILE MONDAY NIGHT AND TUESDAY NIGHT ESPECIALLY ALONG THE SOUTH COAST.
