NWS Boston/Norton, MA wrote its last area forecast discussion before the first event at Jun 8, 9:27 AM EST, 5 hours 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 1027 AM EDT SUN JUN 8 2008 .SYNOPSIS... HEAT AND HUMIDITY WILL PERSIST EARLY THIS WEEK...WITH THE POTENTIAL FOR RECORD SETTING HEAT MON. A COLD FRONT WILL BRING SOME RELIEF WED...WITH COOLER CONDITIONS TOWARD THE END OF THE WEEK. && .NEAR TERM /THROUGH TONIGHT/... HAZY AND QUITE HUMID THIS AFTERNOON. MORNING SOUNDINGS SHOW 17C AT 850 MB...AND A POTENTIAL MIX TO 800 MB WOULD TAP 14C AIR...AN EUIVILENT OF 19C AT 850 MB. SO MAX TEMPS IN THE 90S...ESP LOW-MID 90S...SEEMS REASONABLE. A COUPLE OF GRIDS IN THE HARTFORD AND LOWELL- MANCHESTER AREAS ARE FORECAST TO TOUCH HEAT INDEX/APPARENT TEMPERATURE LEVELS OF 100F...NOT ENOUGH TO TRIGGER AN ADVISORY BUT CLOSE. CONCERN FOR THE AFTERNOON WILL CONTINUE TO BE THE POTENTIAL FOR CONVECTION. 09Z SREF SHOWS POPS 18-21Z ALL THE WAY TO I-95 WITH THE HIGHEST VALUES IN WESTERN MASS AND NW CONNECTICUT. SEVERE POTENTIAL CONTINUES MINIMAL. JET SUPPORT REMAINS WELL NORTH IN CANADA BASED UPON MARGINAL MID LEVEL WIND FIELDS AND WEAK LAPSE RATES. && .SHORT TERM /MONDAY/... ANY CONVECTION WILL DIMINISH QUICKLY THIS EVENING WITH LOSS OF DAYTIME HEATING. ANOTHER WARM AND MUGGY NIGHT AHEAD WITH PATCHY FOG. MODELS HAVE COME INTO VERY GOOD AGREEMENT REGARDING POSITION OF WEAK BACK DOOR FRONT WHICH IS EXPECTED TO DROP INTO SW NH AND MUCH OF CENTRAL/EASTERN MA MON AFTERNOON. 00Z NAM/GFS/CANADIAN AND 21Z/7 SREFS ALL SHOW POTENTIAL FOR CONVECTION AS THIS BOUNDARY PUSHES INTO UNSTABLE AIRMASS AND PROVIDES SUFFICIENT LOW LEVEL CONVERGENCE. SEVERE THREAT IS QUESTIONABLE GIVEN AXIS OF STRONGEST MID LEVEL WIND FIELD IS N OF OUR AREA AND LAPSE RATES REMAIN RATHER WEAK...BUT A FEW STORMS COULD PRODUCE WIND DAMAGE OR HAIL. MAIN THREAT AREA LOOKS TO BE FROM KEENE TO WORCESTER...BOSTON AND MANCHESTER. DESPITE THIS BOUNDARY PUSHING S...IT WILL BE ANOTHER HOT AND HUMID DAY WITH POTENTIAL FOR RECORD HIGHS TO FALL /ESPECIALLY INLAND/. HEAT INDEX VALUES SHOULD REACH 100 TO 105 FOR A FEW HOURS...SO WE MAY NEED TO ISSUE HEAT ADVISORIES FOR PARTS OF REGION IN LATER FORECASTS. COASTAL LOCATIONS COULD SEE TEMPERATURES DROP OFF A BIT MON AFTERNOON...BUT NOT DRAMATICALLY SO. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... THERE MAY BE SOME ONGOING CONVECTION MON EVENING AHEAD OF A WEAK BACKDOOR FRONT. WE WILL EXTEND CHC POPS INTO MON EVENING...MAINLY FROM S NH THROUGH EASTERN MA WHERE CHANCES APPEAR TO BE GREATEST. OTHERWISE...ANOTHER WARM AND MUGGY NIGHT WITH PATCHY LATE NIGHT FOG POSSIBLE. ANOTHER VERY HOT DAY IS EXPECTED TUE WITH RECORD HEAT POSSIBLE AGAIN. 850 MB TEMPS +21C AND 2M TEMPS SUPPORT MAXES MID TO UPPER 90S IN THE INTERIOR. THERE WILL BE MORE SOUTHERLY FLOW WHICH WILL KEEP SOUTH COAST COOLER AND FLOW MAY WEAKEN ENOUGH FOR SUBTLE SEABREEZES ALONG THE EAST COAST SO WE KEPT BOS IN LOWER 90S...BUT IT COULD BE HOTTER IF NO SEABREEZE. THERE ARE SOME TIMING DIFFERENCES WITH NEXT APPROACHING COLD FRONT FOR TUE NIGHT. GFS IS SLOWER AS IT AMPLIFIES UPSTREAM SHORTWAVE MORE RESULTING IN A SLOWER SOLUTION AND DRY DAY ON TUE. ECMWF IS THE FASTEST OF THE MODELS WITH FRONT APPROACHING W ZONES BY 00Z WED AND NAM BRINGS PRECIP INTO SNE BY LATE TUE. MODEL CONSENSUS FAVORS DRY ON TUE SO WE HAVE JUST SLIGHT CHC POPS IN THE GRIDS LATE TUE ACROSS W ZONES. NAM/GFS/GGEM AND SREF POPS INDICATE BEST CHC OF CONVECTION TUE NIGHT WILL BE NORTH AND WEST OF SNE SO WE HAVE JUST SLIGHT CHC TO CHC POPS...HIGHEST IN THE INTERIOR. TIMING OF FRONT DOES NOT APPEAR TO BE FAVORABLE FOR SVR WX. FRONT SLOWLY MOVES OFF THE COAST WED...BUT 850 MB TEMPS ARE STILL WARM SO MAX TEMPS COULD REACH WELL INTO THE 80S...ALTHOUGH LESS HUMID. THERE COULD BE A FEW LINGERING SHOWERS EASTERN ZONES WED MORNING IF SLOWER TIMING OF FROPA VERIFIES. DRY AND COOLER WEATHER THU. ECMWF AND GFS ARE NOW ON BOARD SHOWING AMPLIFIED UPPER LOW MOVING INTO NORTH ATLANTIC FRI INTO THE WEEKEND RESULTING IN COOL TEMPS WITH ONSHORE FLOW. HOWEVER...GFS ENSEMBLE MEAN AND UKMET SHOW FLATTER TROF FURTHER EAST WITH WARMER TEMPS TRYING TO MOVE BACK IN FOR THE WEEKEND...WHICH IS WHAT 12Z/7 ECMWF WAS ADVERTISING. SO THERE IS STILL SOME UNCERTAINTY WITH HOW THE END OF THE WEEK AND WEEKEND WILL PLAY OUT. WE HAVE TEMPS COOLING DOWN SOMEWHAT FOR FRI/SAT ACROSS EASTERN NEW ENG BUT NOT TO THE EXTENT THAT GFS/ECMWF WOULD INDICATE. && .AVIATION /15Z SUNDAY THROUGH THURSDAY/... HIGH PRESSURE BRINGS MOSTLY CLEAR SKIES...JUST SOME CONVECTIVE DEBRIS MOVING FROM NEW YORK EAST INTO NEW ENGLAND. VFR SHOULD CONTINUE THROUGH THE AFTERNOON. CAPE OF 1500-2000 IN WESTERN AND CENTRAL SECTIONS. WILL GO WITH SCATTERED TSTMS FROM MID AFTERNOON TO EARLY EVENING AND EXPAND A LITTLE FURTHER EAST TO WORCESTER. MVFR IN HAZE ACROSS THE SOUTHERN WATERS...CONVERTING TO FOG TONIGHT. OUTLOOK... MON...MVFR/IFR IN FOG/HAZE EARLY. SCATTERED PM TSTMS KMHT/KBOS. TUE...MVFR/IFR IN FOG/HAZE EARLY...OTHERWIZE VFR. TUE NIGHT...AREAS OF MVFR IN SCT SHOWERS/TSTMS. WED AND THU...VFR && .MARINE... W/SW WINDS TODAY INTO MON WILL REMAIN BELOW 25KT WITH FLAT SEAS. MAIN CONCERN IS FOR HAZE THIS AFTERNOON AND FOG AGAIN LATE TONIGHT. WEAK BACK DOOR FRONT DROPPING S WILL REACH E MA WATERS MON AFTERNOON...AND MAY BE ACCOMPANIED BY SCATTERED THUNDERSTORMS. OUTLOOK...MONDAY NIGHT THROUGH THURSDAY... WINDS GENERALLY SW 10-15 KTS MON NGT THROUGH WED...BECOMING WEST WED NIGHT/THU. SEAS GENERALLY 2-4 FT OVER OPEN WATERS.
