FRANKWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Aug 7, 4:01 PM EDT, 36 minutes earlier.
Area forecast discussion, Aug 7, 4:01 PM EDT, 36 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAUNTON MA 401 PM EDT THU AUG 7 2014 .SYNOPSIS... SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO THIS EVENING...SOME OF WHICH MAY BE STRONG TO SEVERE WITH THREATS FOR HAIL AND GUSTY WINDS. HIGH PRESSURE WILL DOMINATE FROM THIS WEEKEND INTO EARLY NEXT WEEK. LOW PRESSURE MAY APPROACH AROUND THE MIDDLE OF NEXT WEEK. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... 400 PM UPDATE... UPPER LEVEL TROUGH AND ASSOCIATED CLOSED LOW WILL REMAIN ACROSS THE REGION LATE THIS AFTERNOON. THIS ANOMALOUS LOW HAS DROPPED 500 MB TEMPS DOWN TO -19C PER SPC MESO SITE AND AT 700MB THE 0C LINE HAS SUNK SOUTH OF LONG ISLAND. THIS HAS CREATED A STRONG COLD POOL OVER THE REGION. BECAUSE OF THE HEATING OF THE DAY COMBINED WITH THIS COLD POOL...LAPSE RATES HAVE STEEPEN GREATLY ALLOWING FOR CONVECTION TO DEVELOP. LATEST MESO-ANALYSIS SHOWERS THE BETTER MID-LEVEL LAPSE RATES HAVE SHIFTED MORE TOWARD PORTLAND ME AND MANCHESTER NH. MU CAPE VALUES ARE STILL 1000 J/KG. OVER THE NEXT FEW HOURS BELIEVE THE STORM COVERAGE WILL DISSIPATE AND BE MORE CONFINED TO THE EAST MASS COASTLINE. K INDEX VALUES HAVE DROPPED A LOT ACROSS THE CT/WESTERN MASS SO DO NOT ANTICIPATE ANY MORE STORMS TO DEVELOP. ALSO THE ATMOSPHERE HAS BEEN WORKED OVER A LOT FROM THE STORMS ACROSS CENTRAL AND NE MASS SO THIS TREND IS DOWNWARD. COLD POOL CONTINUES TO DROP SO RI AND SE MASS/CAPE WILL BE THE PRIMARY FOCUS OVER THE NEXT HOUR OR TWO AS THAT ATMOSPHERE IS RIPE. AGAIN WHERE THE SEA BREEZE HAS DEVELOPED...COULD BE THE MAIN FOCUS ON THE STRONGER STORMS. TONIGHT... SHOWERS AND THUNDERSTORMS WILL COME TO AN END AFTER SUNSET. THIS WILL ALLOW FOR HIGH PRESSURE TO BUILD INTO THE REGION. CLEAR SKIES AND LIGHT WINDS OVERNIGHT WILL ALLOW FOR RADIATIONAL COOLING. OVERNIGHT TEMPS WILL DROP TO THE LOW TO MID 50S WITH THE METRO REGIONS NEAR BOS/PVD DROPPING DOWN TO 60F. BECAUSE OF THE PRECIP THIS AFTERNOON...LOW LEVEL MOISTURE WILL REMAIN ACROSS THE REGION AS WEAK INVERSION SETS UP. THIS WILL ALLOW FOR FOG TO DEVELOP...ESP IN VALLEY AND TYPICALLY PRONE REGIONS. LOW CONFIDENCE ON HOW DENSE IT WILL BE SO THIS WILL NEED TO BE WATCHED OVERNIGHT. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/... FRIDAY INTO FRIDAY NIGHT... WEAK HIGH PRESSURE WILL CONTINUE INTO TOMORROW. HOWEVER WITH THE UPPER LEVEL TROUGH AND COLD CORE LOW OVER US THERE IS A LOW PROBABILITY OF A FEW ISOLATED SHOWERS. BEST LOCATION WILL BE ACROSS THE NORTH AND EASTERN PORTION OF THE REGION...CLOSEST TO THE COLD POOL. SOME CAPE INDICES REACH CLOSE TO 1000 J/KG AND WITH LAPSE RATES STEEPENING AGAIN...CAN NOT RULE OUT SMALL HAIL AND GUSTY WINDS. THESE SHOWERS WILL NOT BE AS WIDESPREAD AS TODAY...BUT VERY ISOLATED IN NATURE. ANY SHOWERS/STORMS THAT DEVELOP WILL DISSIPATE BY SUNSET LEADING TO ANOTHER ROUND OF CLEAR COOL NIGHT. ALTHOUGH NOT AS COOL AS TONIGHT...TEMPS WILL DROP DOWN TO THE MID 50S TO LOW 60S. ANOTHER ROUND OF PATCHY GROUND FOG IS POSSIBLE OVERNIGHT. && .LONG TERM /SATURDAY THROUGH THURSDAY/... OVERVIEW AND MODEL PREFERENCES... MEDIUM RANGE MODEL SUITE CONTINUES TO SIGNAL AN EXTENDED PERIOD OF DRY CONDITIONS AS H5 UPPER PATTERN THE EASTERN HALF OF THE U.S. INDICATES RIDGE BUILDING FROM THE GREAT LAKES TO HUDSON BAY SLOWLY SHIFTING E INTO EARLY NEXT WEEK. BEYOND MIDDAY TUESDAY...MODELS AND ENSEMBLES INDICATING THIS BROAD PATTERN SHIFTS OFFSHORE WHILE H5 SHORT WAVE DIGS OUT OF CENTRAL CANADA...APPROACHING THE GREAT LAKES AROUND MID WEEK WITH LOWERING HEIGHTS AND SURFACE LOW PRES WAVE MOVING SE. THE QUESTION AT THIS POINT WILL BE HOW AMPLIFIED THIS PATTERN BECOMES BEYOND WEDNESDAY...WHETHER IT WILL SLOW DOWN OR REMAIN PROGRESSIVE. AT THIS POINT...SIGNAL IS FOR PROGRESSION LATE INTO THE MEDIUM RANGE PERIOD. AT THE SURFACE...LOOKS LIKE AN EXTENDED PERIOD OF DRY PLEASANT CONDITIONS INTO AT LEAST TUESDAY...THEN EXPECT CLOUDS AND CHANCE POPS TO PUSH IN WITH INCREASING HUMIDITY ON S-SW WINDS AROUND THE LATE TUE THROUGH LATE WED TIMEFRAME. NOTING OP MODEL RUNS ARE IN FAIRLY GOOD AGREEMENT...THOUGH SOME QUESTIONS AS TO THE TIMING OF THE ONSET AND EXIT OF THE PRECIP AS ONE WOULD EXPECT THIS FAR OUT. USED A BLEND OF OPERATIONAL MODELS EARLY...THEN LEANED TOWARD AN OP MODEL AND ENSEMBLE BLEND AFTER MONDAY. DETAILS... SATURDAY THROUGH MONDAY... HIGH PRES RIDGE AT SURFACE AND ALOFT SLOWLY BUILDS OUT OF THE GREAT LAKES REGION SAT ACROSS THE NORTHEAST SUN AND MON WILL PROVIDE PLEASANTLY DRY SUMMER WEATHER. DEWPTS WILL RUN IN THE 50S ON SAT...THEN MAY APPROACH THE LOWER 60S ESPECIALLY ALONG THE COAST BOTH SUN AND MON. EXPECT TEMPS TO RUN CLOSE TO SEASONAL NORMS ALL THREE DAYS...EXCEPT MAY DROP TO AROUND 5 DEGS BELOW NORMS ACROSS THE HIGHER TERRAIN OF SW NH/W MA EACH NIGHT WITH LIGHT/VRBL OR CALM WINDS. THE LIGHT PRES GRADIENT ACROSS THE REGION ALSO SIGNALS WEAK SEA BREEZES ALONG THE COAST...SO TEMPS COULD BE A BIT COOLER THERE. EXPECT HIGHS EACH DAY WILL REACH EITHER SIDE OF 80...POSSIBLY AS HIGH AS THE MID 80S ACROSS THE LOWER CT VALLEY. TUESDAY... MODELS CONTINUE TO SIGNAL H5 SHORT WAVE DIGGING OUT OF CENTRAL CANADA TOWARD THE GREAT LAKES. WINDS WILL BECOME MORE S-SW OVER TIME AHEAD OF THIS SYSTEM...WHICH WILL ALSO BRING MID AND HIGH CLOUDS WITH WARM AIR ADVECTION. LOOKS LIKE SUBSIDENCE FROM THE HIGH TO THE E MAY HOLD THROUGH THE DAYLIGHT HOURS...THEN MAY START TO SEE CHANCE POPS MOVE INTO WESTERN AREAS AFTER MIDNIGHT TUE NIGHT. STILL SOME QUESTION AS TO TIMING OF THE APPROACHING SYSTEM. WEDNESDAY AND THURSDAY... SIGNAL REMAINS TO KEEP THE SHORT WAVE PROGRESSIVE ACROSS THE REGION WED/WED NIGHT...THOUGH LOOKS LIKE BEST SHOT FOR SCT SHOWERS/ISOLD TSTMS. 12Z GFS REMAINS THE SLOWER OF THE THREE MAIN OP MODEL RUNS IN KEEPING THE BACK EDGE OF THE PRECIP ACROSS THE REGION THROUGH AT LEAST MIDDAY THU...WHILE THE 00Z EC AND 12Z GGEM PUSHES OFFSHORE BY THEN. HOWEVER...12Z EC IS STARTING TO SIGNAL SLOWER PROGRESSION AS WELL...SO SOMETHING TO KEEP AN EYE ON. FOR NOW...HAVE CARRIED SLIGHT CHANCE POPS THROUGH MIDDAY THU AND DID KEEP MENTION OF ISOLD TSTMS...THEN DRY CONDITIONS...BUT LOWER CONFIDENCE ON THIS PORTION OF THE FORECAST DUE TO TIMING ISSUES. && .AVIATION /20Z THURSDAY THROUGH TUESDAY/... FORECASTER CONFIDENCE LEVELS... LOW...LESS THAN 30 PERCENT. MODERATE...30 TO 60 PERCENT. HIGH...GREATER THAN 60 PERCENT. SHORT TERM...HIGH CONFIDENCE. VFR FOR MANY OF THE SITES. HOWEVER...-SHRA AND SOME TSRA HAVE DEVELOPED ACROSS THE REGION AND SHOULD LAST INTO THE EVENING HOURS. MVFR/IFR POSSIBLE IN THESE ALONG WITH GUSTY VRB WINDS AND POSSIBLY EVEN SMALL HAIL. ACTIVITY DIMINISHES AFTER SUNRISE. ANTICIPATING SKC WITH LIGHT NW- WINDS. GROUND FOG POSSIBLE FOR THOSE TERMINALS SHELTERED BY THE WINDS OVERNIGHT. FRIDAY INTO FRIDAY NIGHT...VFR WITH SCT-BKN CIGS AROUND 5 KFT UNDER BREEZY NW- FLOW. A ISOLATED TO SCT SHRA IS POSSIBLE...MAINLY ACROSS THE NORTHERN TERMINALS...BUT HAVE LOW CONFIDENCE. PATCHY GROUND FOG COULD DEVELOP AGAIN OVERNIGHT. KBOS TERMINAL...MODERATE CONFIDENCE. SHRA/TSRA SHOULD IMPACT THE TERMINAL THIS AFTERNOON BEFORE ENDING BY SUNSET. KBDL TERMINAL...HIGH CONFIDENCE IN TAF. OUTLOOK...SATURDAY THROUGH TUESDAY... HIGH CONFIDENCE THROUGH PERIOD. SATURDAY THROUGH MONDAY...VFR CONDITIONS. MAY SEE LATE NIGHT/EARLY MORNING FOG EACH NIGHT...WITH BEST SHOT SAT NIGHT. SEA BREEZES LIKELY EACH DAY. TUESDAY...VFR. MID AND HIGH CLOUDS WILL BEGIN TO MOVE ACROSS THE REGION AHEAD OF APPROACHING SYSTEM. MAY SEE WIDELY SCT SHOWERS MOVE INTO CT VALLEY AND N CT TUE AFTERNOON...BUT LOWER CONFIDENCE ON THIS TIMING. && .MARINE... FORECASTER CONFIDENCE LEVELS... LOW...LESS THAN 30 PERCENT. MODERATE...30 TO 60 PERCENT. HIGH...GREATER THAN 60 PERCENT. SHORT TERM...THROUGH FRIDAY...HIGH CONFIDENCE. STILL A LINGERING SOUTH SWELL ACROSS THE SOUTHERN WATERS BUT THIS WILL DISSIPATE OVER THE NEXT FEW HOURS. MAIN CONCERN THIS AFTERNOON AND EARLY THIS EVENING IS FOR THE POTENTIAL OF SHOWERS AND THUNDERSTORMS TO IMPACT THE NEAR-SHORE WATERS ESPECIALLY ALONG E/SE MA. SOME OF THESE STORMS MAY BE STRONG WITH GALE FORCE WINDS AND FREQUENT LIGHTNING. OVERNIGHT...THE WEATHER WILL QUIET DOWN AND CONTINUE INTO FRIDAY UNDER NW-WINDS. GOOD BOATING WEATHER IS EXPECTED THROUGH FRIDAY NIGHT. OUTLOOK...SATURDAY THROUGH TUESDAY...HIGH CONFIDENCE. SATURDAY-MONDAY NIGHT...EXPECT W-NW WINDS AT 10 KT OR LESS THROUGH SUN...SHIFTING TO E-SE SUN NIGHT-MON. SEAS 3 FT OR LESS. TUESDAY...SE WINDS AROUND 10 KT.
