NATIONAL WEATHER SERVICE NEW YORK NY
145 PM EDT THU JUN 3 2010
.SYNOPSIS...
LOW PRESSURE AND ITS ASSOCIATED FRONTAL SYSTEM PASSES ACROSS THE

THE AREA INTO SATURDAY. ANOTHER LOW PRESSURE AND FRONT PUSHES ACROSS
THE REGION SATURDAY NIGHT. THIS FRONT TRACKS EAST INTO EARLY NEXT
WEEK.

.SYNOPSIS...
LOW PRESSURE AND ITS ASSOCIATED FRONTAL SYSTEM PASSES ACROSS THE
AREA LATER TODAY AND TONIGHT. THE FRONT STALLS IN THE VICINITY OF
THE AREA INTO SATURDAY. ANOTHER LOW PRESSURE AND FRONT PUSHES ACROSS
THE REGION SATURDAY NIGHT. THIS FRONT TRACKS EAST INTO EARLY NEXT
WEEK.
&&
.NEAR TERM /THROUGH TONIGHT/...
EXPECTING SEVER WEATHER ACROSS THE AREA THIS AFTERNOON. AS LOW
CLOUDS DISSIPATED...SURFACE HEATING ALLOWED SBCAPES TO JUMP TO
1500 TO 2000 J/KG FROM NYC NORTH AND WEST...AND 1000 OVER NYC AND
SW CT. EXPECT STORMS TO FIRE OUT A HEAD OF A WEAK COLD FRONT AND
MAY BE ENHANCED BY OROGRAPHICS.
SHEAR IS LIMITED BUT WITH IMPRESSIVE CAPE AND HI PRECIPITABLE
WATER VALUES...PULSE-TYPE STORMS ARE THE MOST LIKELY. HOWEVER MORE
ORGANIZED LINES/BANDS POSSIBLE WITH COLD POOL INDUCED OUTFLOW.
SEVERE THUNDERSTORM WATCH #250 IS IN EFFECT UNTIL 8PM.
HIGHEST PROBABILITY IS THE LOWER HUDSON VALLEY ND NRN NJ EARLY
THIS AFTERNOON...WITH CHANCES INCREASING EASTWARD INTO THE
AFTERNOON. THE BIGGEST UNCERTAINTY IS EASTERN LONG ISLAND AND
COASTAL CT...WHERE FOG AND STRATUS ARE KEEPING CONDITIONS
RELATIVELY COOL.
HIGH PRECIPITABLE WATER CONTENT WILL LEAD TO HEAVY DOWNPOURS IN
ANY STRONGER STORMS...AND THUS URBAN/FLASHY STREAM FLOODING.
&&
.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
COLD FRONT SLOWLY MOVES ACROSS THE AREA AND STALLS OVERNIGHT.
LINGERING INSTABILITY WILL RESULT IN SCATTERED CONVECTION INTO THE
EVENING...THEN ACTIVITY SHOULD BEGIN TO DIMINISH IN BOTH COVERAGE
AND INTENSITY AS THE NIGHT PROGRESSES.
SCATTERED TO WIDELY SCATTERED CONVECTION POSSIBLE FRIDAY AS FRONT
ACTS AS A FOCUS FOR AT LEAST SOME ACTIVITY. ANY LIFT AT ALL WILL
ALLOW THE PARCEL TO ASCEND AS CAPES REMAIN IN THE 500 TO 1000
J/KG RANGE DURING MAX HEATING. AGAIN...COVERAGE WILL BE LIMITED
THOUGH SO POPS REMAIN IN CHANCE CATEGORY.
FRIDAY NIGHT SHOULD BE DRY FOR THE MOST PART AS FRONT REMAINS IN OUR
VICINITY. SLIGHT CHANCE POPS AT BEST. THEN ATTENTION TURNS TOWARD
SATURDAY AS NEXT AREA OF LOW PRESSURE PASSES TO OUR NORTH. AMPLE
INSTABILITY AND LIFT WILL SET THE STAGE FOR MORE SHOWERS AND
THUNDERSTORMS.
TEMPS REMAIN ABOVE NORMAL THROUGH THE PERIOD AS MOS GUIDANCE
SUGGESTS.
HIGH HUMIDITY THROUGH THE PERIOD.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
BETTER CONSISTENCY WITH EC AN OUTLIER EARLY IN THE PERIOD. FRONT
MOVES THROUGH SATURDAY NIGHT AND SWEEPS EAST SUNDAY. WEAK UPPER
TROUGH COULD TRIGGER A FEW SHOWERS SUNDAY...BUT THAT SHOULD BE
ABOUT IT AS DRIER AIR MOVES IN. HIGH PRESSURE THEN SLOWLY BUILDS
IN THROUGH TUESDAY...BUT WITH AN ISOLATED THUNDERSTORM MONDAY
AFTERNOON AS A 500 MILLIBAR TROUGH AXIS MOVES THROUGH. THERE ARE
INDICATIONS OF A POSSIBLE MID LEVEL SHORTWAVE ALOFT PASSING NEARBY
OR THROUGH THE AREA ON TUESDAY...BUT WOULD THINK THAT THE COLUMN
WOULD BE TOO DRY FOR RAINFALL. LIKELY DRY ON WEDNESDAY WITH HIGH
PRESSURE HANGING ON.
TEMPERATURES EXPECTED TO BE NEAR NORMAL THROUGH THE LONG TERM
PERIOD.
&&
.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
FOG/STRATUS BURNING OFF AT WESTERN TERMINALS...BUT HANGING ON OVER
LONG ISLAND AND COASTAL CT. DELAYED VFR CONDS UNTIL AS LATE AS 17Z
AT KBDR/KISP AND LATER AT KGON.
COLD FRONT WILL APPROACH FROM THE WEST THIS AFTERNOON...SPARKING
SCATTERED SHOWERS/TSTMS. WITH UNCERTAINTY OVER TIMING AND COVERAGE...HAVE
STILL NOT YET INCLUDED SHOWERS OR THUNDERSTORMS IN TAF...ONLY CB
MENTION IN CLOUD GROUPS. A FEW OF THE STORMS MAY REACH STRONG TO
SEVERE LEVELS...WITH STRONG WINDS AND LARGE HAIL. THE BEST CHANCE
OF THIS IS ACROSS NORTHERN AND WESTERN TERMINALS AND FROM EARLY AFTERNOON
INTO EARLY EVENING.
TONIGHT...TSTM THREAT DIMINISHES...BUT SCATTERED SHOWERS ARE
STILL POSSIBLE AS FRONT STALLS. MVFR OR LOWER CONDS POSSIBLE IN
FOG...PARTICULARLY WHERE HEAVIER RAIN FALLS FROM CONVECTIVE
ACTIVITY AND ACROSS FAR EASTERN TERMINALS.
