Flood and Hail in Rhode Island, September 3, 2013

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
346 PM EDT TUE SEP 3 2013

.SYNOPSIS...
SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS SOUTHEAST NEW
ENGLAND THIS AFTERNOON INTO EVENING. THESE STORMS WILL BE STRONG
TO SEVERE WITH DAMAGING WINDS...LARGE HAIL...HEAVY RAIN AND THE
THREAT OF FLASH FLOODING...AND EVEN THE POSSIBILITY OF A BRIEF
TORNADO/WATERSPOUT. COLD FRONTS ARE EXPECTED THURSDAY AND SUNDAY.
EACH FRONT WILL BRING SCATTERED OR WIDELY SCATTERED SHOWERS
FOLLOWED BY DRY COOLER AIR.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
4 PM HIGHLIGHTS...

 * STRONG TO SEVERE THUNDERSTORMS OVER RI AND SOUTHEAST MA
 * THREATS OF DAMAGING WINDS...LARGE HAIL...HEAVY RAIN
 * WITH HEAVY RAIN...FLASH FLOODING WILL AGAIN BE POSSIBLE

EVALUATING SPC MESOANALYSIS...COMPLEX OF SHOWERS AND THUNDERSTORMS
CONTINUES IN THE REGION OF BEST INSTABILITY...EFFECTIVE SHEAR...
AND DEEP-LAYER FORCING. THREATS OF LARGE HAIL...DAMAGING WINDS...
HEAVY RAIN AND FLASH FLOODING...AND EVEN THE POTENTIAL OF A BRIEF
SPIN-UP TORNADO/WATERSPOUT REMAINS POSSIBLE. IT IS LIKELY THAT
THIS COMPLEX WILL WEAKEN AND DIMINISH EAST AS IT INTERACTS WITH
MARINE AIR AND LESSER FAVORABLE CONVECTIVE ELEMENTS ACROSS THE
GULF OF MAINE.

HAVE ADJUSTED POPS AS BEST AS POSSIBLE WITH THE LATEST HRRR
GUIDANCE. IT DOESN/T HANDLE OUTCOMES QUITE SUCCINCTLY...BUT IT
DOES THE BEST. HIGH CATEGORICAL POPS EXTEND ACROSS A MAJORITY OF
SOUTHEASTERN NEW ENGLAND...FROM NORTHEAST CONNECTICUT UP TOWARDS
BOSTON AND ADJACENT SOUTH SHORE...SOUTHEAST TOWARDS CAPE COD AND
THE ISLANDS...AS WELL AS THE SOUTH COAST OF RHODE ISLAND AND
MASSACHUSETTS. THREATS HAVE BEEN PLACED IN THE FORECAST WHEREVER
POPS ARE LIKELY OR GREATER.

TONIGHT...

SURFACE COLD FRONT WILL PUSH OFFSHORE ALONG WITH SHOWER AND
THUNDERSTORM ACTIVITY. EXPECTING LAST OF THE ACTIVITY TO BE EAST OF
THE MARINE ZONES BY MIDNIGHT. MID- TO UPPER-LEVEL CLOUDS LINGERING
THROUGH THE REGION AS THE MAIN MID-LEVEL TROUGH AND ATTENDANT
REMNANT IMPULSE TRANSLATES THROUGH THE REGION. COOLER AND DRIER AIR
FILTERING IN WITH WESTERLY FLOW. AM NOT EXPECTING FOG TO BE AN ISSUE
OTHER THAN PERHAPS IN SHELTERED VALLEYS. SURFACE HIGH PRESSURE
BUILDING INTO THE REGION TOWARDS MORNING. LOWS AROUND THE MID-50S...
COOLER ALONG THE SHORE.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
WEDNESDAY...

COOL DRY DAY ON TAP AS AIR BUILDS SOUTH OUT OF CANADA. EXPECTING
WESTERLY FLOW PREVAILING AND BOUNDARY LAYER MIXING UP TO H85. SHOULD
SEE DRY SURFACE DEWPOINTS AROUND THE LOW-50S WITH PREVAILING
WESTERLY FLOW. WINDS MAY BE WEAK ENOUGH DURING THE AFTERNOON TO
ALLOW FOR SEA-BREEZE DEVELOPMENT ALONG THE IMMEDIATE EAST-COAST
OF MASSACHUSETTS. SCATTERED CUMULUS POSSIBLE DURING THE DAY...
MAINLY ACROSS THE INTERIOR. MID- TO HIGH-LEVEL CLOUDS BUILDING
LATE WITH APPROACHING SECONDARY COLD FRONT. HIGHS AROUND THE
UPPER-70S TO LOW-80S.

WEDNESDAY NIGHT...

SECONDARY COLD FRONT PUSHES INTO THE REGION AROUND THE CONTINUAL MID-
TO UPPER-LEVEL TROUGHING PATTERN. WINDS VEERING SOUTHWESTERLY AHEAD
OF THE FRONT POSSIBLY BECOMING BREEZY AT 10 TO 15 MPH. CONSIDERING A
STRONG ATTENDANT MID-LEVEL IMPULSE ACCOMPANYING THE SURFACE COLD
FRONT ALONG WITH DIFFLUENCE ALOFT AND SUPPORT WITHIN THE LEFT-FRONT
QUADRANT OF THE UPPER-LEVEL JET...SHOULD SEE STRONG DEEP-LAYER
FORCING OF AVAILABLE MOISTURE TO WARRANT CHANCE POPS. COLD FRONT
WILL BE DRAPED ACROSS THE REGION BY THURSDAY MORNING. LITTLE TO NO
INSTABILITY EXPECTED SO WILL KEEP WITH SHOWERS. LOWS AROUND THE
UPPER-50S.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...

BIG PICTURE... MOST OF THE LONG TERM PERIOD SHOWS A STEADY PATTERN
WITH A TROUGH OVER THE NORTHEAST USA/EASTERN CANADA AND AN UPPER
RIDGE OVER THE WESTERN USA.  TWO SHORTWAVES RIDE THROUGH THE
TROUGH...ONE THURSDAY AND THE SECOND AOURND SUNDAY. DURING EARLY
NEXT WEEK THIS PATTERN CONVERTS INTO A ZONAL FLOW ACROSS THE
NORTHERN TIER STATES WHILE THE SUBTROPICAL RIDGE MAINTAINS OVER
THE SOUTHERN USA.

THE DAILIES...

THURSDAY... COLD FRONT SWEEPS ACROSS THE REGION...ASSOCIATED WITH
THE FIRST OF THE TWO SHORTWAVES.  JET POSITIONS SHOW GOOD UPPER
DIVERGENCE OVERLAYING LOW LEVEL CONVERGENCE...MOVING OFFSHORE BY THE
EVENING. CROSS SECTIONS SHOW MEAGER MOISTURE AND PRECIPITABLE WATER
VALUES ARE FORECAST IN THE 1-1.5 INCH RANGE.  WE HAVE BUMPED POPS UP
TO LOW-END CHANCE BASED ON ON THE AVAILABLE DYNAMICS...BUT NO HIGHER
DUE TO THE LIMITED MOISTURE. MIXING TO 850 MB WOULD BRING MAX TEMPS
65 TO 75...INCREASED SUNSHINE/DEEPER MIXING WOULD MEAN 70S.  WINDS
IN THE AFTERNOON TURN TO NORTH AND POSSIBLY TO NORTHEAST ALONG THE
COAST. A NORTHEAST WIND WOULD KEEP EAST COASTAL TEMPS A COUPLE OF
DEGREES COOLER.

INLAND WINDS IN THE MIXED LAYER INCREASE DURING THE MID TO LATE
AFTERNOON WITH 20 KNOT WINDS ALOFT BY 00Z. THIS SUGGESTS GUSTY NORTH-
NORTHWEST WINDS LATE IN THE DAY AFTER THE COLD FRONT MOVES THROUGH.
MODEL GRID VALUES DO NOT HANDLE THIS WELL...SO WE MANUALLY BUMPED
GUST VALUES WITH MAX VALUES 18-20 KNOTS.

MUCH COOLER AIRMASS BEHIND THE COLD FRONT WITH DEWPOINTS 35-45F AND
WINDS DIMINISHING TO LIGHT. EXPECT A FEW INTERIOR SECTIONS TO DIP A
LITTLE BELOW 40F BUT NOT TO FROST LEVELS.  REMAINING INTERIOR
SECTIONS IN THE 40S AND L-M50S AT THE COASTLINE.

FRIDAY-SATURDAY... HIGH PRESSURE BUILDS OVER THE REGION WITH FAIR
DRY WEATHER.  COOLEST TEMPS ALOFT OCCUR FRIDAY...THEN MODERATE AS
THE HIGH MOVES OFFSHORE SATURDAY.  ON FRIDAY...MIXING TO 850 MB
WOULD SUPPORT MID TO UPPER 60S WHILE MIXING TO 800 MB WOULD BRING
LOW TO MID 70S.  WITH FULL SUN AND LIGHT WINDS WE WILL GO DEEPER ON
MIXING DEPTH BUT NOT ALL THE WAY TO 800MB. SEA BREEZE WILL KEEP
COASTAL TEMPS A COUPLE OF DEGREES COOLER. TEMPS SATURDAY SHOULD
EASILY REACH THE 70S...AND SUFFICIENT MIXING WOULD SUPPORT MAX TEMPS
AROUND 80F. WE WILL STAY CLOSE TO GUIDENCE FOR SATURDAY.

SUNDAY... UPPER LOW OVER ALASKA EJECTS A SHORTWAVE MIDWEEK WHICH
DIVES THROUGH HUDSON BAY TO NEW ENGLAND BY SUNDAY.  THIS WILL DRIVE
ANOTHER COLD FRONT SOUTH THROUGH OUR AREA DURING SUNDAY OR SUNDAY
NIGHT. MUCH OF THE JET SUPPORT FOR THIS LOOKS TO BE ALONG THE
CANADIAN BORDER.  SIMILAR PRECIP WATER VALUES TO THURSDAY.  WE WILL
RUN WITH SLIGHT CHANCE POPS FOR NOW.

MONDAY-TUESDAY... HIGH PRESSURE BUILDS OVER THE REGION WITH MORE DRY
WEATHER. DIFFERENCES TOWARD THE END OF DAY 7 WITH THE GFS KEEPING
THE HIGH IN CONTROL WHILE THE EMCWF MOVES THE HIGH OFFSHORE TUESDAY
AND MAKES ROOM FOR SOME SHOWERS TUESDAY NIGHT. FOR NOW WE WILL GO
WITH THE DRY GFS SOLUTION.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
FORECASTER CONFIDENCE LEVELS...

LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

OVERVIEW...MODERATE CONFIDENCE...

18Z UPDATE...

EVEN THOUGH IFR-LIFR FOG PERSISTS...TSRA IS ANTICIPATED ALONG THE
SOUTH COAST AND SOUTHEAST NEW ENGLAND INTO EVENING. HAVE A VCTS
MENTION FOR EAST NEW ENGLAND TERMINALS WITH THE POSSIBLE THREAT
AHEAD OF THE APPROACHING COLD FRONT. WITH ANY TSRA...MVFR/IFR
IMPACTS POSSIBLE...HAVE GONE WITH TEMPO GROUPS WITH BEST TIMING OF
THREATS.

COLD FRONT SWEEPS OFFSHORE THIS EVENING RESULTING IN SHRA/TSRA
IMPACTS TO DIMINISH. CIGS AND VSBYS LIFT TO VFR. CONDITIONS
PERSIST THROUGH WEDNESDAY WITH LIGHT WESTERLY FLOW WHICH MAY ALLOW
SEA- BREEZES ALONG THE IMMEDIATE COASTS. A SECONDARY COLD FRONT
AND THE CHANCE OF SHOWERS RE-EMERGES FOR INTERIOR TERMINALS
WEDNESDAY NIGHT INTO THURSDAY MORNING. ANTICIPATING LOW-VFR CIGS
WITH MINIMAL IMPACT TO VSBYS.

KBOS TERMINAL...MODERATE CONFIDENCE IN TAF. WILL KEEP A 2 HOUR
MENTION /19-21Z/ OF VCTS. TSRA ACTIVITY MAY STAY MAINLY SOUTH AND
EAST. SEA-BREEZE POSSIBLE DURING THE DAY WEDNESDAY.

KBDL TERMINAL...MODERATE CONFIDENCE IN TAF. HAVE REMOVED ALL
MENTION OF TSRA.

OUTLOOK...THURSDAY THROUGH SUNDAY...

MAINLY VFR THROUGH THE PERIOD.  GUSTY NORTH-NORTHWEST WINDS TO 20
KNOTS THURSDAY.  BRIEF MVFR/IFR POSSIBLE IN SHOWERS THURSDAY AND
AGAIN SUNDAY. PATCHY IFR IN EARLY MORNING FOG FRIDAY AND SATURDAY.

.MARINE...
FORECASTER CONFIDENCE LEVELS...

LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

SHORT TERM...MODERATE CONFIDENCE.

18Z UPDATE...

BOATERS ALONG THE SOUTH COAST SHOULD BE AWARE OF STRONG TO SEVERE
THUNDERSTORMS CONTAINING FREQUENT LIGHTNING...LARGE HAIL...GALE
FORCE WINDS...AND THE POSSIBILITY OF WATER SPOUTS. SEAS WILL
LIKELY BUILD LOCALLY IN RESPONSE TO STORMS. EXPECT SPECIAL MARINE
WARNINGS INTO THIS EVENING AS ACTIVITY PROGRESSES EAST OUT OF LONG
ISLAND AND IMPACTS THE WATERS AROUND CAPE COD AND THE ISLANDS.

EXPECT ACTIVITY TO BE WELL OUT TO SEA BY AROUND MIDNIGHT AS A COLD
FRONT SWEEPS ACROSS THE WATERS. EXPECT SOUTHWESTERLY WINDS TO BACK
MORE WESTERLY. DURING THE DAY WEDNESDAY...NEAR-SHORE SEA- BREEZES
WILL BE POSSIBLE...OTHERWISE LIGHT WESTERLY FLOW WILL ALLOW FOR
ANY ROUGH SEAS TO RELAX. DURING WEDNESDAY NIGHT WINDS WILL TURN
MORE SOUTHWESTERLY AND WE COULD SEE SOME ENHANCEMENT WITH 10 TO 15
KNOTS IN RESPONSE TO AN APPROACHING COLD FRONT TOWARDS THURSDAY
MORNING.

OUTLOOK...THURSDAY THROUGH SUNDAY...

TWO COLD FRONT MOVE THROUGH...ONE ON THURSDAY AND A SECOND ON
SUNDAY.  BRIEF SHOWERS WITH EACH.  NORTH WINDS BEHIND THE THURSDAY
FRONT MAY BECOME NORTHEAST ESPECIALLY OVER THE EAST MASSACHUSETTS
COASTAL WATERS WITH GUSTS TO 20 KNOTS. SOUTHWEST WINDS SATURDAY
MAY GUST 20-22 KNOTS...COMING CLOSE TO THE SMALL CRAFT ADVISORY
THRESHOLD.
