AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE UPTON NY
130 PM EDT FRI JUL 2 2004

.SHORT TERM (TODAY)...
A SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED FOR THE ENTIRE AREA...SO
WILL UPDATE PUBLIC AND MARINE ZONES TO REFLECT THIS.

SHORTWAVE WITH STRONG UPPER LOW OVER SOUTHERN QUEBEC WILL SLOWLY
SLIDE SOUTHEAST INTO NORTHERN NEW ENGLAND DURING THE DAY WITH DECENT
VORTICITY PASSING OVER EASTERN TWO-THIRDS OF CWA THIS AFTERNOON. AT
THE SURFACE...A COLD FRONT WHICH IS ALIGNED NE-SW OVER THE EASTERN
GREAT LAKES WILL SLOWLY PUSH TOWARD THE COAST BY LATE THIS EVENING.
TO THE EAST...A PRE-FRONTAL TROUGH RUNS N-S ALONG THE NY-CONN BORDER
DOWN INTO THE METRO AREA. LAPS ANALYSIS SHOWS THE BEST INSTABILITY
LIES EAST OF THIS SURFACE TROUGH...ALONG THE THETA-E RIDGE AXIS. 12Z
OKX SOUNDING CONFIRMS THIS WITH LOW-MID LEVEL LAPSE RATES OF 7
C/KM...SURFACE CAPE OF 3100 J/KG...AND LI OF -7. WILL CONTINUE WITH
HIGHEST CHANCE POPS FOR THE EASTERN ZONES TODAY AS THE COLD FRONT
OVER THE GREAT LAKES/OHIO VALLEY STATES JUMPS INTO THE TROUGH AXIS
THIS AFTERNOON. AFTER LOW CLOUDS AND FOG BURN OFF BY 14Z...THE
COMBINATION OF DAYTIME HEATING...WEAK FRONTAL CONVERGENCE...
INCREASING 0-6KM DIRECTIONAL SHEAR TO AROUND 40 KTS...MODERATE
INSTABILITY...DRIER MID-LEVEL AIR ADVECTING IN...AND SOME LEFT FRONT
JET REGION SUPPORT...WILL RESULT IN SCATTERED CONVECTION THIS
AFTERNOON WITH ISOLATED STRONG TO SEVERE THUNDERSTORMS. THE LACK OF
A STRONG TRIGGER MAY BE A SAVING GRACE...ALTHOUGH WITH CONVECTIVE
TEMPS IN THE LOW 80S WONT NEED MUCH OF A PUSH. WILL HAVE TO WATCH
FOR DEVELOPMENT ALONG ANY SEABREEZE BOUNDARIES AND EASTERN EDGE OF
PRE-FRONTAL TROUGH. WITH THIS SCENARIO...THE MAJOR THREAT WITH
DEVELOPING STORMS WOULD BE THE POTENTIAL FOR DAMAGING WIND GUSTS AND
LARGE HAIL. OTHERWISE...FORECAST LOOKS ON TRACK.

ADDITIONAL UPPER AIR DATA WILL BE AVAILABLE THIS AFTERNOON...AS
STATION KOKX WILL CONDUCT AN 18Z RADIOSONDE OBSERVATION DUE TO THE
THREAT OF SEVERE WEATHER.
&&

.HYDROLOGY...ISOLATED ONE-QUARTER TO ONE-HALF INCH AMOUNTS POSSIBLE
IN LATE DAY SHOWERS AND THUNDERSTORMS. THIS WILL HAVE LITTLE OR NO
IMPACT ON AREA RIVERS AND STREAMS.
&&

.AVIATION...AREAS OF MVFR VSBYS FOR HAZE. EXPECT WDLY SCT-SCT TSRA
ACTIVITY FROM ABOUT 18Z THROUGH 03/02Z. THESE STORMS WILL BE CAPABLE
OF PRODUCING WIND GUSTS TO 35KT...HAIL AND AREAS OF HEAVY RAIN.
VSBYS AND CIGS ASSOCIATED WITH TSRA WILL BE IFR. FRONTAL BOUNDARY
SWINGS THROUGH EARLY THIS EVENING...ENDING THREAT FROM NORTHWEST TO
SOUTHEAST.

&&

.MARINE...LOCAL VSBY REDUCTIONS IN TSTMS POSSIBLE THIS AFTERNOON AND
EVENING...OTHERWISE QUIET ON THE WATERS THROUGH SUNDAY EVENING.
SEAS MAY COME UP TO SCA CRITERIA LATE SUN NIGHT INTO EARLY MON
MORNING WITH LONG-FETCH SOUTHERLY FLOW OF ABOUT 15 KT.
&&

.PREVIOUS DISCUSSION...

SHORT TERM (TONIGHT THROUGH SUNDAY)...
FOLLOWING THE COLD FRONTAL PASSAGE THIS EVENING...A DRY...WARM
HOLIDAY WEEKEND WILL BE ON TAP. SATURDAY WILL FEATURE ABUNDANT
SUNSHINE AIDED BY A DRY NW FLOW ALOFT. HIGH PRESSURE BUILDS IN BOTH
ALOFT AND AT THE SURFACE. A WEAK RETURN FLOW SETS UP LATE IN THE DAY
AS THE SURFACE RIDGE AXIS SLIPS OFFSHORE. SUNDAY WILL SEE AN
INCREASE IN HUMIDITY...BUT SHOWERS ARE LIKELY TO HOLD OFF UNTIL
SUNDAY NIGHT AS WARM ADVECTION STRENGTHENS.

LONG TERM...(MONDAY THROUGH THURSDAY)...
WESTERLIES TO REMAIN ACTIVE THROUGH THE PERIOD...SENDING A SERIES OF
COLD FRONTS THROUGH THE FORECAST AREA DURING THE WEEK...THE FIRST
LATE MON...AND OTHER TOWARD THE END OF THE WEEK. EACH FRONT WILL BE
PRECEDED BY AN INCREASE IN HUMIDITY AND TEMPERATURES AT OR ABOVE
NORMAL VALUES. SCATTERED CONVECTION IS ALSO A LIKELIHOOD ALONG AND
AHEAD OF EACH BOUNDARY.
