Area forecast discussion, Aug 13, 2:51 PM EDT, 4 hours 43 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 251 PM EDT SAT AUG 13 2005 ...SEVERE THUNDERSTORM WATCH UNTIL 10 PM FOR ALL OF CONNECTICUT, RHODE ISLAND AND ALL OF MASSACHUSETTS EXCEPT FOR THE OUTER ISLANDS... .SHORT TERM (TONIGHT THROUGH SUNDAY NIGHT)... COMPLEX WX PATTERN NX 36 HOURS. SOUPY HOT AIRMASS WITH PWS OF 2 INCHES HEATED TO NEAR 100 DEGREES A FEW LOCATIONS THIS AFTERNOON. CONVECTION NOW FIRING UP WELL TO OUR WEST BUT ON 30-40 KT WRLY MID LEVEL FLOW THIS ACTION SHOULD MARCH STEADILY E LATE THIS AFT AND EVENING. ATM APPEARS ACTION WILL BE FOCUSED N OF A BDR-PYM LINE BUT GIVEN HIGH CAPES AND NOT MUCH OF A CAP...TRW POSSIBLE ANYWHERE INLAND OF THE COAST. SVR THREAT IS STILL OF CONCERN GIVEN 30-40 KT MID LVL WIND AND VERY HIGH CAPE ACRS THE FA. MICROBURSTS THE PRIMARY ISSUE. GIVEN HOT AIRMASS AND HIGH TDS...NOT LIKELY TO SEE ACTIVITY COLLAPSE THIS TIME AS SUNSET APPROACHES...WITH SHORTWAVE SUPPORT BELIEVE SRN NY CONVECTION MAY MAKE ITS WAY THRU FA BETWEEN 21Z-05Z. GFS CONTINUES STEADY ON DRIFING FRONT INTO SRN NH THEN TAKING WAVE ALONG THE FRONT SUN PM. THAT KEEPS THE CWA IN THE HUMID AIRMASS AND IN THE WARM SECTOR WITH MORE CONVECTION LIKELY SUN. SOMEWHAT WEAKER MID LVL FLOW BUT LOTS OF MOISTURE SHOULD PRODUCE TORRENTIAL RAINFALL IN STRONGEST TSTMS. TRAINING WILL BE PRIMARY MECHANISM FOR ANY FFW POTENTIAL. FOLLOWED MAV/GFS POPS THRU THIS FCST PERIOD. WHILE MAXES SUN AGAIN LKLY TO BE IN THE LOW 90S OUT WEST...HEAT INDICES NOT NEARLY AS HIGH AS TODAY AND THUS STAYS BELOW THE 2-DAY CRITERIA. && .LONG TERM (MONDAY THROUGH NEXT SATURDAY)... THE SURFACE FRONT SHOULD BE THROUGH MOST OF THE REGION BY 12Z MONDAY...WITH THE EXCEPTION OF THE SOUTH COAST. HOWEVER...THE UKMET IS NOTICEABLY SLOWER THAN THE NAM/NGM/GFS. FOR NOW WILL GO WITH THE QUICKER SOLUTIONS SINCE THEY ARE IN THE MAJORITY AND COOL OUTFLOW FROM CONVECTION SUNDAY NIGHT SHOULD GIVE THE BOUNDARY AN EXTRA PUSH. HOWEVER...IF THE UKMET VERIFIES THE FRONT WOULD NOT COME THROUGH UNTIL MONDAY AFTERNOON. EVEN THOUGH THE SURFACE FRONT WILL BE THROUGH THE REGION MONDAY MORNING MID LEVEL FLOW LOOKS TO BE SOUTHWESTERLY SO THERE COULD BE SOME OVER RUNNING PRECIPITATION FOR AT LEAST THE FIRST PART OF MONDAY. THEREFORE...WILL GO WITH CHANCE POPS MAINLY ALONG AND SOUTH OF THE MASSACHUSETTS PIKE. ALSO...COULD BE SOME LEFTOVER ELEVATED INSTABILITY FOR THUNDER ALONG THE SOUTH COAST. HIGHS WILL BE MUCH COOLER ON MONDAY AND MAY ONLY BE IN THE LOW TO MID 70S ALONG THE COASTAL PLAIN WITH NORTHEAST WINDS AND LOTS OF CLOUDS. QUIET WEATHER SHOULD DOMINATE MONDAY NIGHT THROUGH TUESDAY NIGHT. ON WEDNESDAY...A WEAK UPPER LEVEL DISTURBANCE WILL SLIDE ACROSS OUR NORTHERN ZONES IN THE AFTERNOON. WITH A LACK OF SURFACE CONVERGENCE AND MOISTURE WILL CONTINUE A DRY FORECAST. AN ISOLATED AFTERNOON OR EVENING SHOWER CAN NOT BE RULED OUT IN THE NORTHERN ZONES BUT NOT WORTH MENTIONING BESIDES AT 20 POP IN THE GRIDDED DATABASE. MEX GUIDANCE LOOKS GOOD BUT WILL GO A FEW DEGREES COOLER IN THE NORMALLY COOLER OUTLINED LOCATIONS AT NIGHT WITH GOOD RADIATIONAL COOLING. COULD SEE THE MERCURY DOWN TO AROUND 50 TUESDAY NIGHT IN A FEW OF THE NORMALLY COOLEST LOCATIONS. WARMER AND MORE HUMID AIR ALTHOUGH NOT NEARLY BAD AS TODAY WILL RETURN TO THE REGION THURSDAY AND PARTICULARLY ON FRIDAY. THIS WILL BE OUT AHEAD OF OUR NEXT COLD FRONT. GFS LOOKS TOO FAST WHEN COMPARING IT TO THE ECMWF AND HPC IS ALSO BUYING INTO THE SLOWER SOLUTION. THEREFORE...WILL CONFINE SHOWER AND THUNDERSTORM CHANCES UNTIL LATE FRIDAY NIGHT AND POSSIBLY NOT UNTIL SATURDAY. WITH 850 MB TEMPERATURES ON THE ECMWF WARMING TO +17C WILL GO A FEW DEGREES WARMER THEN MEX GUIDANCE TOWARDS THE END OF THE WEEK. && .AVIATION... VFR TO MVFR IN HAZE THRU THE EVENING...BUT LIFR ACK AND SURROUNDING AREA AS LARGE ST DECK AS DVLPD FROM JUST E OF BID THRU ACK. CONVECTION WILL PRODUCE PERIODS OF IFR AND GSTS 40 KTS AT THE VERY LEAST. && .MARINE... IN NEAR-TEAM...SCA UP PRIMARILY FOR EXPECTED 4-5 FT SEAS LATE TONIGHT AND SUN. WNDS NOT LKLY TO REACH SCA CRITERIA THU 00Z MON. COLD SURGE BEHIND FRONT NRN MOST WATERS MIGHT SEE A GUST OR TWO BUT LATEST GFS ACTUALLY SLOWER WITH FROPA MON MORNING AS IT REACHES THE COAST. IN THE LONGER TERM...MAY SEE A FEW BRIEF 25 KNOT WIND GUSTS MONDAY MORNING WITH NORTHEAST COOL SURGE OVER THE WATER.
