AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 410 PM EDT FRI JUL 23 2010 .SYNOPSIS... A WARM FRONT WILL BRING SHOWERS AND PERHAPS A FEW THUNDERSTORMS THROUGH THIS EVENING...THEN HOT AND HUMID CONDITIONS WILL MOVE IN THIS WEEKEND JUST INLAND FROM THE COAST. THE NEXT COLD FRONT WILL LIKELY BRING SCATTERED SHOWERS AND THUNDERSTORMS SATURDAY AFTERNOON THROUGH SUNDAY...BUT ALSO PROVIDE RELIEF FROM THE HEAT AND HUMIDITY EARLY NEXT WEEK. ANOTHER COLD FRONT IS EXPECTED LATE IN THE WEEK. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... MUCH OF THE WARM FRONTAL SHOWERS ACROSS SNE SHOULD EXIT THE REGION FROM WEST TO EAST THIS EVENING AS THE LOW LEVEL JET MOVES TO THE EAST. A FEW ELEVATED TSTMS ALSO POSSIBLE LATE THIS AFTERNOON AND THIS EVENING AS NEG SWI AND HIGHER KI MOVE IN. WARM FRONT ACROSS CENTRAL NYS AND E PA WILL MOVE INTO SNE TONIGHT AND TEMPS WILL LIKELY RISE SLOWLY OVERNIGHT ESPECIALLY SOUTH OF THE PIKE. MCS DEVELOPING OVER THE GT LAKES AT THE EDGE OF THE DRY SLOT SHOULD PASS TO THE SW ACROSS MID ATLC REGION WHERE BEST SFC INSTABILITY...BUT CANT RULE OUT ISOLD TSTMS ANYTIME LATER TONIGHT AS WARM FRONT MOVES THROUGH...WITH BEST CHANCE ACROSS SW ZONES. AREAS OF LOW CLOUDS AND PATCHY FOG ALSO DEVELOPING AS HIGHER DEWPOINTS ADVECT IN. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/... WARM FRONT WILL BE MOVING NWD ACROSS N ZONES SAT MORNING BUT IT APPEARS IT MAY STALL NEAR OR JUST NORTH OF NE MA. ANY LOW CLOUDS AND PATCHY FOG WILL BURN OFF IN THE MORNING...BUT THE CLEARING MAY BE DELAYED IN POSTIONS EASTERN MA ESPECIALLY NEAR THE COAST WHERE EASTERLY FLOW IS EXPECTED TO PERSIST MOST OF THE DAY. 850 MB TEMPS 18-19C BUT CLOUDS AND EAST WINDS WILL WILL KEEP TEMPS NEAR THE E MA COAST CONSIDERABLY COOLER THAN INTERIOR LOCATIONS RESULTING IN SHARP TEMPS GRADIENT ACROSS SNE. BRUNT OF THE HEAT WILL AFFECT THE CT VALLEY SAT WITH TEMPS REACHING LOW/MID 90S WITH TEMPS COOLING TO UPPER 70S AND LOWER 80S NE MA. VERY HUMID CONDITIONS EXPECTED ACROSS SNE WITH DEWPOINTS REACHING LOW TO MID 70S AND HEAT INDICES ABOVE 100 DEGREES EXPECTED IN THE CT VALLEY WHERE HEAT ADVSY WAS ISSUED. NEAR 100 DEGREE HEAT INDICES ALSO POSSIBLE FOR A FEW HOURS NE CT AND W RI. DESPITE WARM TEMPS ALOFT AND MEAGER MID LEVEL LAPSE RATES...HEAT AND HIGH DEWPOINTS WILL MAKE UP FOR THIS AND AIRMASS WILL BECOME QUITE UNSTABLE WITH MAX CAPES 2000-3000 J/KG IN THE CT VALLEY WITH LESSER CAPES FURTHER EAST. WE SHOULD SEE SCT TSTMS DEVELOP ESPECIALLY IN THE AFTERNOON IN THE INTERIOR. STRONGER MID LEVEL WINDS WILL BE WEST OF NEW ENG BUT HIGH CAPES AND NEARBY BOUNDARY WILL BE ENOUGH FOR THE POTENTIAL FOR SEVERE WX. WET MICROBURSTS WILL BE MOST COMMON IN THIS HIGH CAPE LOW SHEAR ENVIRONMENT. CONVECTION MAY CONTINUE INTO A GOOD PART OF SAT NIGHT AS PREFRONTAL TROF MOVES INTO THE REGION AND A MORE ORGANIZED MCS IS POSSIBLE AS MID LEVEL JET MOVES IN FROM THE WEST SAT NIGHT. MID LEVEL COOLING FROM THE NORTH WOULD FAVOR AREAS NORTH OF THE PIKE. HIGH PWAT AIRMASS SUGGESTS HEAVY RAINFALL WILL ALSO BE POSSIBLE WITH ANY STORMS SAT AND SAT NIGHT. && .LONG TERM /SUNDAY THROUGH FRIDAY/... OVERALL...FAIRLY GOOD AGREEMENT AMONGST THE MODELS FOR THE LONG TERM. THE GFS IS A BIT QUICKER ON TIMING THEN THE ECMWF...THIS IS FAIRLY NORMAL. COOLER...LESS HUMID...AND MORE SEASONABLE WEATHER IS EXPECTED THROUGH THE FIRST PART OF THE WEEK AS LOW PRESSURE EXITS THE AREA AND HIGH PRESSURE BUILDS IN. A COLD FRONT IS POSSIBLE MIDWEEK AS LOW PRESSURE MOVES ACROSS SOUTHERN CANADA BRINGING ANOTHER CHANCE FOR SHOWERS AND THUNDERSTORMS TO SOUTHERN NEW ENGLAND. SUNDAY...A SHORTWAVE APPROACHES SOUTHERN NEW ENGLAND KEEPING SHOWERS AND THUNDERSTORMS GOING THROUGH THE MORNING HOURS. ADDITIONAL STORMS MAY BE POSSIBLE IN THE AFTERNOON...AS THE COLD FRONT APPROACHES THE AREA. WHERE THESE STORMS MAY FORM IS LIMITED BY HEATING AND WHERE THE BEST INSTABILITY ENDS UP BEING AFTER THE FIRST SET OF STORMS MOVE THROUGH. HIGHS SHOULD GENERALLY BE IN THE 80S. LOWS WILL RANGE FROM THE UPPER 50S IN THE NORTHWESTERN ZONES TO UPPER 60S IN THE URBAN CENTERS. LOW TO MODERATE CONFIDENCE. MONDAY AND TUESDAY...A BRIEF PERIOD OF SHORTWAVE RIDGING WILL BRING MORE SEASONABLE AND LESS HUMID WEATHER TO SOUTHERN NEW ENGLAND. HIGHS WILL BE IN THE LOW 80S WITH THE APPARENT /FEELS-LIKE/ TEMPERATURE VERY CLOSE TO OR EVEN SLIGHTLY BELOW THE ACTUAL TEMPERATURE. MODERATE TO HIGH CONFIDENCE. WEDNESDAY THROUGH FRIDAY...TIMING DISCREPANCIES IN THE MODELS BECOME MORE APPARENT WITH A LOW PRESSURE SYSTEM AND COLD FRONT MOVING THROUGH SOUTHERN NEW ENGLAND SOMETIME WEDNESDAY OR THURSDAY. THIS WILL BRING A CHANCE OF SHOWERS AND THUNDERSTORMS BACK TO THE REGION THROUGH THE END OF THE WEEK. LOW CONFIDENCE FOR THIS PERIOD. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... THIS AFTERNOON...VFR EASTERN TERMINALS LOWERING TO MVFR CIGS BY 23Z. MVFR CIGS AND VSBYS CENTRAL AND WESTERN PORTIONS OF SOUTHERN NEW ENGLAND WITH AREAS OF IFR VSBYS IN AREAS OF R+ AND FOG.

PERIODS OF MVFR/IFR LIKELY IN SHOWERS AND THUNDERSTORMS IN THE MORNING AND AGAIN IN THE AFTERNOON. OTHERWISE VFR. MONDAY AND TUESDAY...HIGH CONFIDENCE VFR. WEDNESDAY...LOW CONFIDENCE. MAINLY VFR BUT A POSSIBILITY OF SHOWERS AND THUNDERSTORMS MAY RESULT IN PERIODS OF MVFR/IFR CONDITIONS. && .MARINE... WINDS WILL REMAIN BELOW SCA THRESHOLDS THROUGH THE PERIOD. MAY SEE A PERIOD OF SW WINDS 20 KT TONIGHT AND AGAIN SAT NIGHT OVER SOUTH COASTAL WATERS. WNAWAVE GUIDANCE IS TOO HIGH WITH ITS SW FLOW BIAS. WE UNDERCUT ABOUT 30 PERCENT WHICH STILL BRINGS 5-6 FT SWELLS INTO THE SOUTHERN WATERS SAT NIGHT. OUTLOOK...SUNDAY THROUGH WEDNESDAY... SUNDAY..INCREASING SOUTHWEST FLOW AHEAD OF AN APPROACHING COLD FRONT MAY BRING 4 TO 6 FOOT SEAS ACROSS THE SOUTHERN OUTER-WATERS. AN INVERSION WILL LIKELY KEEP WIND GUSTS BELOW CRITERIA ACROSS THE OPEN WATERS. SEAS WILL LIKELY DIMINISH OVERNIGHT. MONDAY AND TUESDAY...HIGH PRESSURE MOVES OVER THE WATERS WHICH WILL KEEP WINDS AND SEAS BELOW SCA CRITERIA. WEDNESDAY...WINDS AND SEAS MAINLY REMAIN BELOW SCA CRITERIA. THERE IS A LOW PROBABILITY THAT WIND GUSTS NEAR SHORE MAY NEAR 25 KTS ON OCCASION DURING THE AFTERNOON. && .BOX WATCHES/WARNINGS/ADVISORIES...
