AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 335 PM EDT THU JUN 9 2011 .SYNOPSIS... STRONG HEATING AHEAD OF A COLD FRONT WILL GENERATE POWERFUL THUNDERSTORMS ACROSS SOUTHERN NEW ENGLAND. THE FRONT WILL MOVE OFFSHORE TONIGHT. HIGH PRESSURE THEN BRINGS DRIER AND MORE SEASONABLE WEATHER FOR FRIDAY. LOW PRESSURE AND A COLD FRONT MAY APPROACH SATURDAY NIGHT INTO MONDAY...BRINGING UNSETTLED WEATHER AND A COOL EASTERLY FLOW. HIGH PRESSURE && .NEAR TERM /UNTIL 1 AM FRIDAY MORNING/... LINE OF TSTMS ACROSS VT TO SOUTH CENTRAL NY. THESE ARE MOVING EAST AND EXTRAPOLATE ACROSS OUR AREA BETWEEN ROUGHLY 19Z AND 02Z. EARLY AFTERNOON CAPES HAVE CLIMBED TO 2500-3000 JOULES IN NORTHWEST MASS AND SOUTHWEST NH ARE CLIMBING ELSEWHERE. LI VALUES ARE -4 TO -8. 850 MB WINDS OF 25-30 KNOTS AND 500 MB WINDS OF 40 KNOTS ARE SUFFICIENTLY STRONG AND INCREASING WITH HEIGHT...AND ARE IN A SIMILAR DIRECTION. EXPECT TSTMS TO INCREASE TO STRONG/SEVERE LEVELS AS THEY MOVE INTO THIS AIRMASS WITH WIND ORGANIZATION SUPPORTING SQUALL LINES WITH STRONG WIND GUSTS AND LARGE HAIL. EXPECT TSTMS TO MOVE OFF/DIMINISH AS THEY MOVE OFFSHORE THIS EVENING. THE 12Z NAM AND GFS SUPPORT MORE CLEARING THAN PREVIOUSLY...WE HELD ONTO SOME CLOUDS IN SOUTHERN AREAS DURING THE MIDDLE OF THE NIGHT BUT WITH A CLEARING TREND BY MORNING. TEMPERATURES ARE A BLEND OF MAV AND MET VALUES. && .SHORT TERM /1 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/... FRIDAY...HIGH PRESSURE BUILDS LESS HOT BUT DRIER WEATHER WITH DEWPOINTS FALLING INTO THE 50S. SURFACE WINDS TURN TO ONSHORE WHICH WILL KEEP EAST AND SOUTH COAST AREAS COOLER THAN INLAND. INCREASING HIGH CLOUDS LATE IN THE DAY FROM THE SOUTHWEST. TEMPERATURES AT 850 MB ARE 8-10C ON THE NAM AND 11-13C ON THE GFS. WE USED A MET/MAV BLEND WEIGHTED TOWARD THE MAV...WITH MID 70S TO MID 80S. && .LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/... WITH SEVERE TSTM WATCH IN EFFECT...WILL ONLY GIVE BRIEF OVERVIEW FOR WHAT IS EXPECTED DURING THIS TIMEFRAME. NOT A WHOLE LOT OF TIME TO DIGEST MODELS...AS WARNINGS HAVE BEGUN. DID NOT NOTE A WHOLE LOT OF OVERALL CHANGES FROM WEDNESDAY/S MODEL RUNS. APPEARS THE UPPER LEVEL PATTERN SUGGESTED BY THE MODEL SUITE IS IN PRETTY GOOD AGREEMENT...BUT IN BROAD RIDGING OR NEARLY ZONAL FLOW...TIMING OF SURFACE SYSTEMS IS SUSPECT AT LEAST THROUGH THIS WEEKEND. MODELS ALSO APPEAR A BIT MORE STABLE WITH THE CUTOFF LOW IN THE UPPER FLOW MOVING ACROSS THE GREAT LAKES LATE IN THE WEEKEND INTO EARLY NEXT WEEK...THOUGH SOME MODELS DO HAVE THIS FEATURE A BIT DEEPER THAN OTHERS. LATER IN THE PERIOD...DOES LOOK LIKE THIS CUTOFF WILL DRIFT ACROSS N NEW ENGLAND. FRIDAY NIGHT...STALLED FRONT S OF NEW ENGLAND WILL SLOWLY SHIFT BACK N AS A WARM FRONT. WILL BE A SLOW PROCESS THOUGH AS HIGH PRES TO THE E TRIES TO HOLD TOUGH. EXPECT ONLY LOW CHANCE POPS ACROSS WESTERN AREAS...WITH CLOUDS INCREASING FURTHER E. WILL BE ON THE MILD SIDE FOR OVERNIGHT LOWS...MAINLY IN THE LOWER 50S TO AROUND 60. SATURDAY...EXPECT PRECIP TO PUSH INTO THE ENTIRE REGION BY MIDDAY. INCLUDED LIKELY POPS ACROSS S NH/W MA WHERE BEST LIFT AND MOISTURE CONVERGENCE IS LOCATED. GENERAL ONSHORE WINDS WILL KEEP TEMPS COOLER...THOUGH MAY REACH TO AROUND 70 ACROSS SOUTHERN AREAS CLOSER TO THE APPROACHING WARM FRONT. SATURDAY NIGHT-SUNDAY NIGHT...WITH CUTOFF LOW ACROSS NY STATE...LOW STARTS TO OCCLUDE OUT TO THE W...WHICH WILL SLOW THE PROGRESSION OF THE FRONT EASTWARD. EXPECT LIKELY SHOWERS AND SCT TSTMS ESPECIALLY FROM LATER SAT NIGHT THROUGH EARLY SUNDAY EVENING AS OCCLUSION TRIES TO MOVE ACROSS THE REGION. TEMPS MAY WARM TO THE LOWER-MID 70S ACROSS CT VALLEY AND SOUTHERN AREAS ON SUNDAY...BUT QUESTION HOW FAR N WARM FRONT PROGRESSES. THIS WILL HAVE AN EFFECT ON MAX TEMPS ON SUNDAY. MODELS IN FAIRLY GOOD AGREEMENT IN PUSHING FRONT ACROSS REGION LATER SUNDAY NIGHT. MONDAY...THIS APPEARS TO BE THE TRANSITION DAY...BUT TIMING IS A FACTOR DUE TO MOVEMENT OF CUTOFF LOW. HAVE ENDED THE PRECIP...BUT LEFTOVER SHOWERS MAY LINGER ESPECIALLY ACROSS E MA. HIGH PRES BUILDS ACROSS GREAT LAKES/OHIO VALLEY AND WILL SLOWLY MOVE E. TUESDAY-WEDNESDAY...FOR NOW...HAVE A PARTLY CLOUDY AND DRY FORECAST GOING AS HIGH PRES SLOWLY SHIFTS E...WHICH IS SHOWING PRETTY GOOD CONTINUITY FROM PREVIOUS FORECAST. STILL TIMING ISSUES IN PLACE THIS FAR OUT. THURSDAY...LOW CONFIDENCE WITH THIS PORTION OF THE FORECAST. HIGH PRES BUILDS OFF THE MID ATLC COAST WITH LOW PRES AND FRONT MAY START TO APPROACH.
