AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
416 AM EDT TUE APR 29 2008
.SYNOPSIS...
LOW PRESSURE WILL MOVE ACROSS SOUTHERN NEW ENGLAND THIS MORNING AND
SLOWLY INTENSIFY... THEN ABRUPTLY DEPART THIS AFTERNOON WITH GUSTY
NORTHWEST WINDS IN ITS WAKE. A FRONTAL BOUNDARY WILL DEVELOP OVER THE
MID ATLANTIC STATES THURSDAY AND STAY MAINLY TO OUR SOUTH INTO EARLY
NEXT WEEK BUT PRESENTS A SIGNIFICANT FORECAST PROBLEM FOR THE
WEEKEND.
&&
.NEAR TERM /UNTIL 3 PM THIS AFTERNOON/...
BOX STP IS WELL UNDERDONE BUT NOT SWITCHING MID STREAM AND JUST
REALIZING WE ARE GOING TO HAVE TO ADD ON TO THE STP.
MANY AMTS NOW 2 TO 2.5 INCHES IN HFD COUNTY TO ORH COUNTY AS OF 2 AM
THIS MORNING VIA SKYWARN APRS HOMELAND SECURITY REPORTS AND BLENDS
WELL WITH THE ASOS REPORTS OUT OF HVN COUNTY NEWD.
THE FACT THAT THE BACKEDGE DEEP MOISTURE HAS MOVED A LITTLE EAST OF
ANTICIPATED FOR 330AM...WILL ALLOW ENOUGH RECOVERY BEFORE ANY ADDED
.3 TO .7 INCH AMTS IN THE AFORE MENTIONED WATCH AREAS CAUSES ANY
SHORT TERM SMALL STREAM FLOOD PROBLEMS.
FLSS FOR URBAN SMALL STREAM ISSUES THE REMAINDER OF THIS
MORNING...IF NEEDED.
AS OF 330 AM NO KNOWN STREAM FLOODING.
WHILE DENSE FOG MAY BE A BRIEF ISSUE FOR THE CW AND ADJACENT MA COAST
EARLY THIS MORNING...THINK IT PRUDENT TO KEEP THUNDER POTENTIAL IN
THE FCST FOR THIS MORNING INTO EARLY AFTN...ESP CT RI E MASS.
THE NEG TILT SW ROLLING NEWD THRU THE MID ATLC COULD SLIGHT UP WITH
LIGHTNING BTWN 10Z-12Z...FLEDGLING BURST OF SHOWERS NOW COMING OUT OF
DCA-BWI IS THE PRIME LIGHTNING MATERIAL NR AND JUST NE OF THE VT MAX.
TT NR 55 AND SWI SUBZERO FOR A FEW HOURS THIS MORNING. DONT HAVE PEA
HAIL IN THE FCST BUT 18Z 500MB TEMP COOLING TO LESS -15C BOS AND -24C
BDL MAY BE ENOUGH TO ASSIST IN THUNDER PRODUCTION. IN PART IT DEPENDS
ON HOW FAST THE DRYING FLUX IN NW FLOW LATE THIS MORNING CT RVR
VALLEY AND EWD MIDDAY TO THE MA COAST. DUE TO UNCERTAINTY...LOW PROB
OF THUNDER AND NO MENTION OF HAIL. COULD BE SPS MATERIAL IF WE GET A
CLUSTER OF SMALL HAIL PRODUCING TSTMS WITH ISO GUST 35 KT.
GUSTS...OUR NAM MXG HT RUN OFF THE 08Z30Z FCST KBOX SFC TEMPS
COMBINED WITH GFS GUST ALGORITHM OFFERS 35KT NW WIND GUSTS MONADNOCKS
THIS AFTN. THAT LOOKS A LITTLE HIGH BUT WITH THE STRENGTH OF THE 5H VT
MAX...RAN A SMALL CAP ON GUSTS BUT NOT TOTALLY DISMISSING. IF TEMPS
STAY COLDER THAN FCST...GUSTS WILL BE LESS.
&&
.SHORT TERM /3 PM THIS AFTERNOON THROUGH 6 AM WEDNESDAY/...
AFTER 3PM THIS AFTERNOON...RAPID CLEARING THIS AFTN FM WNW TO ESE.
MAY ALLOW TEMPS TO BRIEFLY RECOVER AROUND 3 OR 4 PM WITH GUSTY NW
WINDS AND ANY REMAINING SHOWERS IN NE MASS ENDING ARD 3 OR 4PM.
TONIGHT...FROST ADVY ISSUED IN AGREEMENT WITH ADJACENT OFFICE.
FROST FREEZE PROGRAM STARTED S COAST ARD APRIL 20 AND N CT EWD THRU
SE MASS MAY 1. WE MOVED IT UP A DAY FOR GROWERS TO BE WARY OF
TONIGHTS POTENTIAL FROST TEMPS...NOT YET A LOCK BUT THE ADVY ISSUED
WITH 75 PCT CONFIDENCE ON PATCHES OF FROST...AND 25 PCT CONFIDENCE ON
SPOTTY FRZG TEMPS WITHIN THE FROST ADVY. HAVE GREATEST CONFIDENCE IN
FROST ACROSS N CT.
IF IT INDEED IT FROSTS...IT WOULD BE SCRAPER MORNING DUE TO HIGH LEFTOVER
SFC MOISTURE CONTENT ASSTD WITH THIS PAST 24HRS OF 1-3 RAINS.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
WEDNESDAY AND THURSDAY...THE MID LEVEL TROUGH EXTENDS INTO SOUTHERN
NEW ENGLAND AND BECOMES NEGATIVELY TILTED. AT THE SURFACE...A
STATIONARY WARM FRONT WILL EXTEND INTO THE WATERS SOUTH OF LONG
ISLAND AND REMAIN THERE THROUGH THE END OF THE WEEK. THE 00Z GFS
AND 00Z NAM KEEP THE FRONT FAR ENOUGH SOUTH OF THE AREA THAT
PRECIPITATION WON/T REACH INTO SOUTHERN NEW ENGLAND ON WEDNESDAY.
THURSDAY...BOTH MODELS INDICATE RAIN MOVING UP FROM THE SOUTH TO
ROUGHLY THE MA PIKE. THE 12Z ECMWF HAS LIGHT RAIN ACROSS ALL OF
SOUTHERN NEW ENGLAND BOTH DAYS. LIKE THE CONSENSUS BETWEEN THE NAM
AND THE GFS BETTER SO WILL GO WITH THAT SOLUTION FOR WEDNESDAY AND
THURSDAY.
LOOKS LIKE TEMPERATURES WILL BE RIGHT AT OR JUST BELOW NORMAL FOR
THIS TIME OF YEAR FOR MUCH OF THE FORECAST PERIOD. THE EXCEPTION TO
THIS WILL BE WEDNESDAY NIGHT WHEN TEMPERATURES WILL DROP BELOW 36
DEGREES ACROSS MUCH OF SOUTHERN NEW ENGLAND WITH SOME LOCATIONS
DROPPING BELOW FREEZING. THE MAIN CONCERN HERE WILL BE NORTHERN
CONNECTICUT... RHODE ISLAND...AND SOUTHEASTERN MASSACHUSETTS WHERE
THE GROWING SEASON HAS ALREADY BEGUN.
THERE APPEARS TO BE ALL SORTS OF UNCERTAINTY IN THE LONG TERM
PORTION OF THE FORECAST THIS MORNING. THE HIGH LATITUDE BLOCK IN
THE MID LEVEL FLOW IS THE POPULAR SOLUTION IN BOTH THE 00Z GFS AND
THE 00Z CANADIAN. THE 12Z ECMWF DOESN/T BUY INTO THIS SOLUTION
QUITE YET. WILL HAVE TO SEE HOW THE 00Z RUN TURNS OUT. THE
DIFFERENCE BETWEEN YESTERDAY MORNINGS MODEL RUNS AND NOW WITH
REGARDS TO THE BLOCK SEEMS TO BE LOCATION WITH THE MOST RECENT RUNS
SHOWING THE BLOCK IN SOUTHEASTERN CANADA. GIVEN THE UNCERTAINTY
AMONGST THE MODELS AND RUN TO RUN UNCERTAINTY...WILL BLEND THE
CURRENT FORECAST WITH THE MOST RECENT GMOS FOR THE FORECAST FRIDAY
AND BEYOND.
