556 AM EDT FRI MAY 12 2006
.SHORT TERM /TODAY THROUGH SATURDAY/...
LONG DURATION HEAVY RAIN EVENT LIKELY FOR FA BUT THERE IS STILL SOME
UNCERTAINTY OF WHERE AXIS OF HEAVIEST RAFL WILL OCCUR THRU THE
PERIOD. INITIALLY HEAVY RAIN WILL BE FOCUSED ACRS LWR CT VLY AND E
SLOPES OF BERKSHIRES...BUT LATEST GUIDANCE SUGGESTING AXIS OF HVY
RAFL WILL SHIFT EWD TNGT AND SAT. AS A RESULT WE DECIDED TO EXPAND
FLOOD WATCH EWD TO I-95 CORRIDOR.
DOWNSTREAM BLOCKING RIDGE OVER MARITIMES FCST TO DRIFT WWD AS
UPPER LOW OVER GT LAKES MOVES SWD THRU SAT. RESULT WILL BE
PERSISTENT DEEP ELY FLOW ACRS SNE WHICH WILL ADVECT HIGH PWATS INTO
REGION SETTING STAGE FOR HEAVY RAIN EVENT.
CURRENTLY AXIS OF HEAVY RAIN IS ACRS SE NY SWD THRU NJ ASSOCD WITH
LOW LEVEL CONVERGENCE FROM SFC BOUNDARY. IMPRESSIVE 6 HR AMOUNTS OF
1.5-2 UPSTREAM ACRS ERN PA FROM 00-06Z. RAIN AREA IS MAKING SLOW
PROGRESS EWD AND WILL MOVE INTO CT VLY AND E SLOPES OF BERKSHIRES
THIS MORNING...WITH RAIN ARRIVING IN EASTERN SECTIONS THIS AFTN AS
DEEP LAYERED OMEGA MOVES EWD. HOWEVER STEADIER RAIN MAY HOLD OFF
TIL TNGT FOR CAPE AND ISLANDS. ELEVATED INSTABILITY PARAMETERS ARE
MARGINAL BUT BASED ON UPSTREAM LIGHTNING WE MENTIONED ISOLD THUNDER
TODAY ACRS SW ZONES.
SFC BOUNDARY WEAKENS TODAY SO FOCUS FOR HEAVY RAINFALL WILL BE AREA
OF LOW LEVEL CONVERGENCE ASSOCD WITH SSE LLJ ACTING ON HIGH PWAT
AXIS. CONVERGENCE IS INITIALLY FOCUSED ACRS WRN ZONES TODAY BUT
MODELS INDICATE PWAT AXIS AND BEST LOW LEVEL CONVERGENCE WILL SHIFT
EWD TNGT/SAT AS SSE JET WEAKENS AND ELY LLJ STRENGTHENS E OF NEW
ENG. THIS SHOULD ALLOW HEAVY RAFL TO SHIFT EWD ACRS EASTERN ZONES
TNGT AND SAT AND MODELS ACTUALLY HINT AT SOME MID LEVEL DRYING ACRS
SW ZONES LATE TNGT AND SAT WHICH WHICH MAY SHUT OFF PCPN IN THIS
AREA.
MODELS AGREE THAT HEAVIEST QPF TODAY WILL BE ACRS W ZONES BUT SHOW
SOME DIFFERENCES TNGT/SAT. NAM CLEARLY FOCUSES HEAVY QPF ACRS NE MA
AND S NH TNGT/SAT WHILE GFS HAS HEAVY QPF FURTHER SWD ACRS CENTRAL
MA INTO RI. WE ARE LEANING TOWARD THE NAM WHICH HAS SUPPORT OF
MAJORITY OF GFS ENSEMBLE MEMBERS WHICH SHOW HEAVIEST RAFL ACRS
CENTRAL/NE MA INTO S NH TNGT AND SAT AND BEYOND. THIS ALSO FITS
WELL WITH CONCEPTUAL MODEL OF QPF MAX IN THE MERRIMACK VALLEY WITH
WITH ELY FLOW.
BOTTOM LINE...WE THINK HEAVIEST QPF FROM THIS EVENT MAY END UP IN
OUR NE ZONES WHERE ISOLD 6 AMOUNTS PSBL DUE TO LONGER DURATION OF
HEAVY RAFL.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
MAIN FOCUS OF THIS PACKAGE WAS THE FORECAST THROUGH MONDAY DAY.
LATEST MODEL RUNS HAVE GOOD AGREEMENT AND CONTINUITY THROUGH SUNDAY
NIGHT. AFTER THAT TIME THOUGH...THE MODEL SOLUTIONS START TO
DIVERGE...MAINLY WITH RESPECT TO TIMING THE EVOLUTION OF THE
EASTERN U.S. MID LEVEL CUTOFF LOW. ALL SAID THE MODELS ARE NOT
VERY DIFFERENT WITH THEIR SOLUTIONS...BUT THEY ARE DIFFERENT ENOUGH
WERE CONFIDENCE IN THE DETAILS IS COMPROMISED.
EXPECTING A DIFFICULTY FORECAST SATURDAY NIGHT INTO SUNDAY. HIGH
PRESSURE OVER SOUTHEAST CANADA SHOULD TRY TO PUSH SOUTHWEST INTO
SOUTHERN NEW ENGLAND...TRAPPING A LOW PRESSURE IN THE MID ATLANTIC
STATES. AM THINKING THE ENCROACHMENT OF THIS HIGH PRESSURE WILL
SERVER TO ENHANCE THE LOW LEVEL ISENTROPIC LIFT IN THE 295-305K
LAYER. THE BIG QUESTION IS...IF THE MID AND UPPER LEVELS DRY OUT
TOO MUCH TO ALLOW FOR SIGNIFICANT RAINFALL SATURDAY INTO SATURDAY
NIGHT.
GFS HAS BEEN VERY CONSISTENT IN SHIFTING THE AXIS OF HEAVY
RAINFALL FROM THE CT RIVER VALLEY TO NORTHEAST MA AND SOUTHERN NH
HAMPSHIRE SATURDAY NIGHT INTO SUNDAY. SO RAN WITH IT AND EXTENDED
THE FLOOD WATCH FARTHER TO THE NORTHEAST.
EVENTUALLY...THE DRY AIR ARRIVING FROM THE NORTHEAST SHOULD TAKE
ITS TOLL AND RESULT IN MORE SHOWERY PRECIPITATION FOR LATE SUNDAY
NIGHT INTO MONDAY.
PERSISTENT EAST WINDS COMBINED WITH A HIGH ASTRONOMICAL TIDE SUNDAY
MORNING COULD RESULT IN MINOR SPLASHOVER ACROSS THE EAST COAST OF
MASSACHUSETTS. THE OTHER ASTRONOMICAL TIDES EARLY NEXT WEEK SHOULD
NOT BE AS HIGH...AND HENCE NOT AS MUCH OF A THREAT. BEACH EROSION
WILL STILL BE A CONCERN.
FEELING IS WE WILL NEED TO INCREASE THE THREAT OF RAIN FOR TUESDAY
INTO TUESDAY NIGHT...BUT WILL KEEP FOCUS OF THIS WEEKEND INTO MONDAY
FOR NOW.
AS FOR TEMPERATURES...ONLY NEEDED TO TWEAK PREVIOUS FORECAST WITH A
BLEND OF LATEST GUIDANCE.

.AVIATION...
WIDESPREAD IFR/LIFR CONDITIONS THROUGH TONIGHT.

.MARINE...
SHORT TERM...WE WILL CONTINUE SMALL CRAFT ADVISORY WITH G30 KTS THRU
SAT. WE CONSIDERED A MINIMAL GALE WARNING BUT 950 MB JET IS 35-40
KTS AND LOW LEVEL INVERSION SHOULD PRECLUDE MIXING OF THESE WINDS TO
THE SFC. WITH PERSISTENT LONG FETCH ELY FLOW SEAS WILL BUILD TO
10-15 FT ON OUTER EASTERN WATERS TNGT AND SAT.
IN THE LONGER TERM FROM SATURDAY NIGHT INTO TUESDAY...A PERSISTENT
EAST FLOW WILL KEEP SEAS RELATIVELY HIGH. SMALL CRAFT ADVISORY
CONDITIONS EXPECTED INTO THE MIDDLE OF NEXT WEEK...MAINLY ACROSS THE
OUTER COASTAL WATERS AND OUTSIDE THE BAYS AND HARBORS.
&&
.HYDROLOGY...
FLOOD WATCH EXPANDED TO I-95 CORRIDOR AND NOW INCLUDES ALL OF
CT...NW RI...SW NH...AND ALL OF MA EXCEPT FOR SE MA AND CAPE/ISLANDS.
RAINFALL TOTALS SHOULD AVERAGE 2 TO 4 INCHES OVER MOST OF SOUTHERN
NEW ENGLAND BY THE TIME THE RAIN TAPERS OFF SUN...WITH POSSIBILITY
OF SPOT 5 OR 6 INCH TOTALS IN FAVORED UPSLOPE REGIONS OF WORCESTER
HILLS...MONADNOCKS...AND MERRIMACK VALLEY.
SMALLER RIVERS AND STREAMS SHOULD BEGIN TO SHOW SHARP RISES FRI
AFTERNOON AND FRI NIGHT IN OUR WESTERN ZONES...BUT PROBABLY NOT
UNTIL SAT FARTHER E. SIGNIFICANT URBAN FLOODING IS ALSO POSSIBLE
DURING THIS TIME.
