A cold front moved across Southern New England producing showers and thunderstorms.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Boston/Norton, MA wrote its last area forecast discussion before the first event at Jun 20, 2:00 PM EST, 16 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 300 PM EDT SUN JUN 20 2010 .SYNOPSIS... A COLD FRONT WILL CROSS SOUTHERN NEW ENGLAND LATE THIS AFTERNOON AND EVENING. A WEAK SECONDARY FRONT WILL MOVE ACROSS MONDAY. PERIODIC UNSETTLED WEATHER DURING THE MIDWEEK PERIOD IS POSSIBLE WHILE A WARM FRONT NEARS THE AREA. HIGH PRESSURE SHOULD BRING DRIER CONDITIONS FOR THE END OF THE WORKWEEK INTO NEXT WEEKEND. && .NEAR TERM /UNTIL 7 PM THIS EVENING/... STRONG LOW-LEVEL LAPSE RATES WITH SURFACE-BASED CAPES UP TO 2500 J/KG FUELING SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON. MID-LEVEL LAPSE RATES ARE NOT VERY GOOD...BUT THERE IS MODEST WIND SHEAR MOVING ACROSS SOUTHERN NEW ENGLAND THIS AFTERNOON. CANNOT COMPLETELY RULE OUT LARGE HAIL JUST YET...BUT IT WILL BE DIFFICULT TO DEVELOP AS LATEST ESTIMATED HEIGHT OF THE WET BULB ZERO IS AT OR ABOVE 12 KFT. MAIN CONCERN FOR THE STRONGER THUNDERSTORMS THIS AFTERNOON AND EVENING WILL BE STRONG DAMAGING WINDS. WITH THE SOUPY AIR MASS... LOCALLY HEAVY RAINFALL IS ALSO POSSIBLE. && .SHORT TERM /7 PM THIS EVENING THROUGH MONDAY NIGHT/... 20/12Z NAM IN GOOD AGREEMENT WITH OTHER MODEL SOLUTIONS...SO USED IT AS THE BASIS FOR THIS FORECAST. WITH MID-LEVEL LAPSE RATES SO MEAGER...EXPECTING CONVECTION TO QUICKLY DIMINISH IN INTENSITY AFTER SUNSET. STILL HAVE TO WAIT UNTIL ABOUT 06Z TONIGHT FOR THE COLD FRONT TO REACH THE COAST...AND A FEW HOURS LONGER FOR IT TO CLEAR CAPE COD AND THE COASTAL WATERS. WEAK HIGH PRESSURE ARRIVES MONDAY INTO MONDAY NIGHT. TEMPERATURES WERE A BLEND OF THE MET/MAV MOS GUIDANCE TONIGHT THROUGH MONDAY NIGHT AS THEY WERE CLOSE. && .LONG TERM /TUESDAY THROUGH SATURDAY/... MEDIUM RANGE MODELS CONTINUE TO INDICATE A NEARLY ZONAL UPPER LEVEL FLOW ACROSS THE NORTHEASTERN U.S. THROUGH MOST OF THIS TIMEFRAME AS W-E ELONGATED RIDGE REMAINS ACROSS THE SOUTHERN TIER STATES. THE BIG FORECAST PROBLEM CONTINUES TO BE WHETHER A FRONTAL BOUNDARY WILL STALL NEAR OR OVER THE REGION...AS WELL AS ANY SHORT WAVES THAT WILL TRAVEL IN THE MEAN UPPER FLOW AND ALONG THIS FRONT. APPEARS TO BE SOME CONTINUITY WITH THE TIMING AND PLACEMENT OF THE FRONT AND WEAK LOWS...WHICH MEANS A PERIOD OF UNSETTLED WEATHER AROUND MID WEEK. BEYOND THURSDAY...TIMING REMAINS RATHER QUESTIONABLE THOUGH SOME INDICATIONS OF IMPROVING WEATHER. TUESDAY...THE HIGH WILL PUSH OFFSHORE DURING THE DAY WHILE A WARM FRONT SETS UP JUST S OF THE REGION. NAM CONTINUES TO BE MOST AGGRESSIVE WITH THIS FEATURE...EVEN DEVELOPING LOW PRES ALONG THIS FRONT. THE GFS AND ECMWF BOTH INDICATE THE OVERRUNNING SETTING UP BUT NOT MUCH IN THE WAY OF A LOW SEEN AT THIS POINT. PRETTY GOOD AGREEMENT THAT CLOUDS WILL INCREASE DURING THE DAY...THEN SCT SHOWERS/TSTMS APPROACH WESTERN AREAS AFTER 18Z IN THE RATHER FAST ZONAL FLOW. MAY NEED TO INCREASE POPS AS TIME GOES ON...DEPENDING UPON WHETHER THE LOW ACTUALLY FORMS. TUESDAY NIGHT THROUGH THURSDAY...MODELS STILL HAVING A TOUGH TIME WITH THE TIMING OF WEAK SHORT WAVES IN THE UPPER LEVEL FLOW AS WELL AS WHETHER THE DEFORMATION ZONE WILL REMAIN CLOSE TO OR OVER THE REGION. AS OF NOW...LOOKS LIKE THE WARM FRONT WILL STALL OVER THE REGION LATE TUESDAY NIGHT INTO WEDNESDAY...THEN A COUPLE OF WEAK WAVES WILL MOVE ALONG IT THROUGH THIS TIMEFRAME. WILL REMAIN RATHER UNSETTLED WITH PERIODS OF SHOWERS/TSTMS AND A LOT OF CLOUDS AROUND. DEPENDING UPON THE FRONT/S PLACEMENT...COULD SEE TEMPS RISE INTO THE 80S MAINLY ACROSS SOUTHERN AREAS. FOR NOW...HAVE KEEP TEMPS MAINLY AROUND 80 DURING WEDNESDAY AND THURSDAY. MAY SEE A SOMEWHAT STRONGER LOW APPROACH DURING THURSDAY...WHICH MAY HELP PUSH THE FRONT S OF THE REGION LATE IN THE DAY. FRIDAY AND SATURDAY...MODELS IN GENERAL AGREEMENT THAT HIGH PRES MAY PUSH OUT OF CENTRAL CANADA...BRINGING DRIER CONDITIONS. NOT A LOT OF CONFIDENCE DUE TO THE FAST FLOW ALOFT. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... THIS AFTERNOON...HIGH CONFIDENCE IN VFR OUTSIDE OF SCATTERED SHOWERS AND THUNDERSTORMS AND AWAY FROM THE SOUTH COAST. IFR CEILINGS LIKELY TO PERSIST ALONG THE SOUTH COAST OF MA AND RI THROUGH AT LEAST 22Z. MVFR EXPECTED IN HEAVIER SHOWERS AND THUNDERSTORMS. KBOS...SCT SHOWERS AND THUNDERSTORMS COULD IMPACT LOGAN AIRPORT THROUGH 00Z. AIRPORT WEATHER WARNINGS MAY NEED TO BE ISSUED FOR LIGHTNING...STRONG WINDS OR HAIL INTO THIS EVENING. TONIGHT...ANY SHOWERS AND TSTMS MOVE OFFSHORE THIS EVENING LEAVING BEHIND VFR CONDITIONS. HOWEVER...IFR CONDITIONS PERSIST ACROSS THE CAPE AND ISLANDS THROUGH 12Z IN FOG. MONDAY AND MONDAY NIGHT...HIGH CONFIDENCE VFR MOST LOCATIONS. LOW CONFIDENCE MVFR IN PATCHY FOG AND STRATUS TOWARD KCQX AND KACK AFTER MIDNIGHT MONDAY NIGHT. OUTLOOK...TUESDAY THROUGH THURSDAY... TUESDAY...MODERATE CONFIDENCE OF VFR EARLY. MODERATE CONFIDENCE ON CIGS LOWERING TO MVFR DURING THE AFTERNOON FROM W-E. SCATTERED SHOWERS/TSTMS PUSH INTO WESTERN AREAS N CT/W MA/SW NH/ AFTER 18Z. TUESDAY NIGHT...MODERATE CONFIDENCE OF MVFR-IFR CIGS/VSBY. SCATTERED SHOWERS/TSTMS AND FOG PATCHES AS A WARM FRONT APPROACHES. WEDNESDAY...MODERATE CONFIDENCE MVFR-IFR CIGS/VSBYS WITH LOW CLOUDS AND FOG PATCHES. SCATTERED SHOWERS/TSTMS CONTINUE. THURSDAY...LOW TO MODERATE CONFIDENCE OF MVFR CIGS/VSBYS WITH SCATTERED SHOWERS/TSTMS MAINLY IN THE MORNING. CONDITIONS MAY IMPROVE TO VFR ACROSS WESTERN AREAS AFTER 20Z. && .MARINE... TONIGHT...A COLD FRONT WILL APPROACH THE WATERS THIS EVENING...AND CROSS THE WATERS BY DAYBREAK MONDAY. SEAS MAY REACH 5 FT ACROSS THE OUTER SOUTH COASTAL WATERS...BUT CONFIDENCE IS NOT HIGH ENOUGH TO WARRANT A SMALL CRAFT ADVISORY. A SPECIAL MARINE WARNING OR TWO MAY HAVE TO BE ISSUED THIS AFTERNOON AND EVENING IN VICINITY OF THUNDERSTORMS. MONDAY AND MONDAY NIGHT...RELATIVELY TRANQUIL WINDS AND SEAS ARE EXPECTED WITH WEAK PRESSURE GRADIENT IN PLACE. OUTLOOK...TUESDAY THROUGH THURSDAY... TUESDAY THROUGH WEDNESDAY...WINDS AND SEAS EXPECTED TO REMAIN BELOW SMALL CRAFT CRITERIA. SCT SHOWERS AND TSTMS TUE NIGHT AND WED.
