AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
906 PM EDT WED MAY 29 2013
.SYNOPSIS...
SHOWERS AND THUNDERSTORMS WILL MOVE ACROSS THE REGION THROUGH THE
PRE DAWN HOURS OF THURSDAY AS A WARM FRONT MOVES ACROSS THE
REGION. EXPECT HAZY...HOT AND HUMID CONDITIONS STARTING THURSDAY
AND LASTING INTO THE UPCOMING WEEKEND AS HIGH PRESSURE SITS OFF
THE EASTERN SEABOARD. A COLD FRONT WILL SLOWLY APPROACH FROM THE
WEST...BRINGING THE THREAT OF SHOWERS AND THUNDERSTORMS FROM LATE
SUNDAY AFTERNOON POSSIBLY INTO TUESDAY. HIGH PRESSURE WILL BRING
DRY CONDITIONS WITH MORE SEASONABLE TEMPERATURES BY THE MIDDLE OF
NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
850 PM UPDATE...
SEVERE THUNDERSTORM WATCH IS IN EFFECT THROUGH 1 AM FOR CENTRAL
AND WESTERN MA/SW NH AND N CENTRAL/NE CT.
LARGE BOW ECHO FEATURE MOVING ACROSS WESTERN MA INTO WESTERN
WORCESTER COUNTY. WARNINGS IN EFFECT NOW FOR THIS. HAVE RECEIVED
MANY REPORTS OF WIND DAMAGE AS WELL AS STREET FLOODING FROM
BERKSHIRE COUNTY. ANOTHER CELL IS HEADING FOR HARTFORD AND TOLLAND
COUNTIES FROM SOUTHERN BERKSHIRE. THIS LINE OF THUNDERSTORMS
WORKING ALONG BEST INSTABILITY ON THE WARM FRONT MOVING ACROSS THE
REGION. CONTINUING TO CLOSELY MONITOR THESE FEATURES AS WARM
FRONT MAKES ITS WAY ACROSS THE REGION.
HAVE UPDATED GRIDS AND FORECASTS TO REFLECT CURRENT CONDITIONS.
PREVIOUS DISCUSSION...
MID-LEVEL LAPSE RATES WILL REMAIN STEEP ENOUGH THAT ANY SHOWERS
AND THUNDERSTORMS MAY BE ABLE TO SUSTAIN THEMSELVES INTO THE
OVERNIGHT. HOWEVER...EXPECT THE BIGGEST THREAT TO BE HEAVY RAIN
AND THE POSSIBILITY OF URBAN AND POOR DRAINAGE FLOODING. RAIN
SHOULD DIMINISH THROUGH THE NIGHT AND THE COMBINATION OF THE WET
GROUND AND DEWPOINTS IN THE 60S WILL RESULT IN PATCHY FOG ACROSS
MUCH OF THE AREA. THESE HIGH DEWPOINTS WILL ALSO KEEP LOW
TEMPERATURES IN THE LOW 60S.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THURSDAY WILL BE THE FIRST DAY IN A POSSIBLE HEAT WAVE. AN UPPER
LEVEL RIDGE CENTERED OVER THE SOUTHEASTERN U.S. BUILDS INTO THE
NORTHEAST. 850MB TEMPS CLIMB TO 15-16C WHICH WITH STEEP MID LEVEL
LAPSE RATES WILL TRANSLATE TO TEMPERATURES CLIMBING INTO THE UPPER
80S TO LOWER 90S ACROSS SOUTHERN NEW ENGLAND. DOWNSLOPING...
WESTERLY WINDS AND MOSTLY SUNNY TO SUNNY SKIES WILL AID IN BRINGING
TEMPERATURES UP. TO BE A HEAT WAVE WE NEED THREE CONSECUTIVE DAYS
WITH TEMPERATURES GREATER THAN 90 DEGREES. THE LAST TIME EACH OF
THE FOUR CLIMATE SITES HAD A HEAT WAVE IS LISTED IN THE CLIMATE
SECTION BELOW.
THURSDAY NIGHT WILL BE A REPEAT OF TONIGHT...LESS THE RAIN. WITH
DEWPOINTS IN THE UPPER 50S TO LOWER 60S...EXPECT LOWS TO BE ABOUT
THE SAME OR A FEW DEGREES HIGHER. AND WITH THE AMOUNT OF
MOISTURE...FOG IS LIKELY TO DEVELOP ONCE AGAIN.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
OVERVIEW AND MODEL PREFERENCES...
MEDIUM RANGE MODEL SUITE IN GOOD AGREEMENT INTO EARLY NEXT WEEK AT
LEAST ACROSS THE CONTIGUOUS U.S. NOTING UPPER LEVEL CUTOFF LOW PRES
ACROSS THE CENTRAL AND UPPER PLAINS STATES WITH LARGE UPPER LEVEL
RIDGE ACROSS THE EAST LATE THIS WEEK. APPEARS THAT THE CUTOFF
MIDWEST LOW WILL SLOWLY FLATTEN AS UPPER LEVEL RIDGE SLOWLY BREAKS
DOWN NEXT WEEKEND. THIS WILL ALLOW SLOW MOVEMENT OF LONG WAVE TROUGH
EASTWARD EARLY NEXT WEEK. MAY SEE PERIOD OF SCATTERED SHOWERS/TSTMS
AS COLD FRONT SLOWLY MOVES ACROSS REGION AROUND THE LATE SUNDAY TO
TUESDAY TIMEFRAME...WITH IMPROVEMENT BY THE MIDDLE OF NEXT WEEK.
TIMING IS SUSPECT THOUGH AS MODELS TEND TO TRY TO BREAK DOWN
AMPLIFIED UPPER PATTERNS TOO QUICKLY.
PLAN ON USING BLEND OF PREVIOUS FORECAST WITH 12Z GFS/00Z ECMWF
/WHICH WERE IN VERY GOOD AGREEMENT INTO EARLY NEXT WEEK/ ALONG WITH
WPC GUIDANCE. FEEL THIS WILL TAKE INTO ACCOUNT SOME TIMING ISSUES
ESPECIALLY AFTER SUNDAY WITH FRONT APPROACH.
THE DAILIES...
FRIDAY-SATURDAY...WITH LONG WAVE RIDGE AND BERMUDA HIGH PRES IN
PLACE ALONG THE EASTERN SEABOARD...WILL SEE HAZY...HOT AND HUMID
CONDITIONS IN PLACE WITH GOOD SW GRADIENT IN PLACE ON FRIDAY AND

HOLD OFF UNTIL SUNDAY AT EARLIEST.
SUNDAY...WILL SEE COOLER TEMPS MAINLY DUE TO INCREASING CLOUDS AS
COLD FRONT STARTS ITS APPROACH. EXPECT SCT SHOWERS/TSTMS TO MOVE IN
DURING THE AFTERNOON FROM NW-SE...HOLDING OFF ACROSS EASTERN AREAS

80S...COOLEST ALONG S COAST...CAPE COD AND ISLANDS.

50 KT...HIGHEST ACROSS RI/SE MA. WILL ALSO SEE VERY HIGH PWATS MOVE
ACROSS WITH THE FRONT...ON ORDER OF 1.75 TO 1.9 INCHES...SO COULD
SEE SOME HEAVY DOWNPOURS IN SOME PRECIP AREAS WHICH COULD CAUSE
LOCALIZED FLOODING. WITH ALL FACTORS IN PLACE...COULD SEE SOME
STORMS APPROACH SEVERE CRITERIA. SOMETHING TO MONITOR CLOSELY.
MONDAY...COLD FRONT WILL SLOWLY MOVE ACROSS REGION DURING THE DAY AS
UPPER LEVEL SYSTEM PUSHES INTO NY STATE. BEST DYNAMICS MOVE
