Area forecast discussion, Aug 5, 4:07 PM EDT, 1 hour 22 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
407 PM EDT SUN AUG 5 2012

.SYNOPSIS...
SHOWERS AND THUNDERSTORMS...SOME STRONG...WILL MOVE THROUGH THE
REGION THIS EVENING. BY MONDAY MORNING A COLD FRONT WILL SWEEP
INTO THE REGION...ENDING THE RAIN THREAT AND RETURN TEMPERATURES
TO NEAR NORMAL. FAIR WEATHER WILL FOLLOW THROUGH MID WEEK.

&&

.NEAR TERM /UNTIL 8 AM MONDAY MORNING/...
AS OF 400 PM EDT SUNDAY...CONVECTIVE THREAT HAS HAD A LOT TO WORK
AGAINST TODAY...AS EXTENSIVE CLOUD COVER AND SCATTERED SHOWERS
THIS MORNING HAS USED UP THE AVAILABLE CAPE. A MESOSCALE CLUSTER
OF THUNDERSTORMS MOVED OUT OF PENNSYLVANIA THROUGH MIDDAY...AND
HAS TRACKED ALONG SOUTHERN LAKE ONTARIO. CLOUDS HAVE CLEARED
SOMEWHAT IN NORTHERN NEW YORK ALLOWING SURFACE TEMPERATURES TO
CLIMB INTO THE UPPER 80S. THIS IS STARTING TO DESTABILIZE THE
ATMOSPHERE...WITH SURFACE BASED CAPES APPROACHING 3000 J/KG. IN
ADDITION...WITH APPROACHING COLD FRONT 0-6KM BULK SHEAR GETTING UP
TO 40 TO 50 KTS. UPPER JET DYNAMICS BECOMING MORE FAVORABLE
THROUGH THE EVENING AS NORTHERN NEW YORK FALLS UNDER RIGHT
ENTRANCE REGION OF 500-250 MB JET. SAINT LAWRENCE COUNTY APPEARS
TO BE UNDER GREATEST SEVERE THREAT AS STORM CLUSTER CONTINUES TO
LIFT NORTHEAST.

SECONDARY ROUND OF STORMS EXPECTED ORIENTED MORE WITH COLD FRONT TRAILING
THE MESO SYSTEM THIS EVENING...AND MOVE WEST TO EAST LATE
AFTERNOON AND EVENING. LESS OF A SEVERE THREAT WITH THESE
STORMS...ALTHOUGH HEAVY RAINFALL AND ISOLATED STRONG WINDS POSSIBLE.

TEMPERATURES IN NORTHERN NEW YORK WILL FEEL AFFECTS OF COLD FRONT
BY MORNING AS LOW AND MID LEVEL DRYING TAKES PLACE ALONG WITH SOME
COLD AIR ADVECTION. TEMPS MAINLY IN 50S IN NORTHERN NEW
YORK...ALTHOUGH CAN'T RULE OUT SOME 40S IN HIGHER TERRAIN AND COOL
SPOTS. 60S IN VERMONT.

HEAVY RAIN THREAT ADDRESSED IN HYDRO SECTION BELOW.

&&

.SHORT TERM /8 AM MONDAY MORNING THROUGH TUESDAY NIGHT/...
AS OF 400 PM EDT SUNDAY...SURFACE HIGH PRESSURE BUILDING INTO
REGION DURING THIS SHORT TERM PERIOD...WHILE BROAD UPPER TROUGH
SETTLES INTO THE EASTERN GREAT LAKES. COMBINATION OF LOW HEIGHTS
AND HIGH AT SURFACE WILL ALLOW FOR BIG DIURNAL TEMP SWINGS WITH
COOL NIGHTTIME LOWS AND SUNNY DAYS.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
AS OF 431 AM EDT SUNDAY...A WEAK RIDGE OF HIGH PRESSURE WILL BE
OVER THE REGION EARLY WEDNESDAY...WITH FAIR AND DRY WEATHER
EXPECTED. ECMWF AND GFS MODELS CONTINUE TO HINT AT SOME SCATTERED
CONVECTION TO DEVELOP ALONG AND NEAR THE INTERNATIONAL BORDER
WEDNESDAY AFTERNOON. HAVE GONE WITH SLIGHT CHANCE POPS FOR SHOWERS
AND THUNDERSTORMS WEDNESDAY AFTERNOON IN THE VICINITY OF THE
INTERNATIONAL BORDER. THE REMAINDER OF THE FORECAST WILL REMAIN
DRY ON WEDNESDAY. EXPECTING DRY WEATHER WEDNESDAY NIGHT...AS ANY
CONVECTION THAT DOES DEVELOP WEDNESDAY AFTERNOON WILL LIKELY
DISSIPATE WITH THE LOSS OF DAYTIME SURFACE HEATING. ECMWF AND GFS
HINTING AT SOME SCATTERED CONVECTION THURSDAY AFTERNOON...SO HAVE
GONE WITH LOW CHANCE POPS FOR SHOWERS AND THUNDERSTORMS. THE
WEATHER WILL BECOME UNSETTLED TOWARD THE END OF THE WEEK...WITH
THE GFS AND ECMWF MODELS SHOWING AN UPPER TROUGH AND A CLOSED
UPPER LOW OVER THE WESTERN GREAT LAKES SLOWLY SWINGING
EASTWARD...BRINGING A CHANCE OF SHOWERS AND THUNDERSTORMS TO THE
REGION FRIDAY AND SATURDAY. COOLER AIR ALOFT WILL WORK INTO THE
REGION ON SUNDAY. HOWEVER...THIS WILL SET THE STAGE FOR MORE RAIN
SHOWERS ON SUNDAY.

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
THROUGH 18Z MONDAY...GENEREALLY VFR EXCEPT SCT IFR VIS IN
THUNDERSTORMS. STRONG GUSTY SOUTH WINDS THROUGH 00Z...THEN WIND
DIMINISHES AND SHIFTS WEST TOWARD 06Z. BY MORNING WINDS AROUND TO
NORTHWEST. PATCHY FOG POSSIBLE IN VALLEY LOCATIONS...HOWEVER LEFT
OUT OF INDIVIDUAL TAFS AS RAIN OCCURRENCE AT TAF SITES WILL
DETERMINE FOG POTENTIAL.

OUTLOOK 12Z MONDAY THROUGH THURSDAY...
MAINLY VFR CONDITIONS OVER THE ENTIRE AREA MONDAY AND CONTINUING
RIGHT THROUGH THURSDAY...WITH SOME AREAS OF MVFR/IFR POSSIBLE IN SCATTERED
SHOWERS AND THUNDRSTORMS THURSDAY AFTERNOON.

&&

.HYDROLOGY...
MOIST AIRMASS AHEAD OF THE COLD FRONT WITH PRECIPITABLE WATERS
APPROACHING 2 INCHES AND 200 PERCENT NORMAL. TALL SKINNY CAPE AND
WARM COALESCENS DEPTHS IN EXCESS OF 3KM WILL ENHANCE RAIN
EFFICIENCY. STORMS HAVE PRODUCED BIG RAIN AMOUNTS IN SHORT
AMOUNTS OF TIME...ROCHESTER NY RECEIVED 1.26 IN ABOUT 40 MINUTES
EARLIER THIS AFTERNOON. HOWEVER FORWARD MOTION OF STORMS WILL
LIMIT RAINFALL OVER ANY ONE AREA...REDUCING FLOOD THREAT. WILL
STILL NEED TO MAINTAIN AWARENESS FOR STORMS REPEATEDLY MOVING OVER
SAME AREA.

&&

.MARINE...
A LAKE WIND ADVISORY IS IN EFFECT TODAY AND TONIGHT...

WINDS AT 10 TO 20 KTS THIS MORNING WILL CONTINUE TO
INCREASE...AND BECOME STRONG AND GUSTY DURING THE AFTERNOON. WIND
SPEEDS OF 25 TO 35 KNOTS WITH HIGHER GUSTS WILL BUILD WAVES TO 2
TO 5 FEET THIS AFTERNOON. THESE STRONG WINDS WILL CONTINUE INTO
THIS EVENING...THROUGH AROUND MIDNIGHT. AFTER MIDNIGHT...WINDS
WILL BECOME 10 TO 20 KTS...WITH WAVES DECREASING TO 1 TO 3 FEET.

THERE IS ALSO A LAKE THUNDERSTORM ADVISORY IN EFFECT THIS
AFTERNOON THROUGH TONIGHT...

AS A COLD FRONT APPROACHES FROM THE GREAT LAKES REGION...SHOWERS

COUNTRY. SOME OF THESE STORMS WILL BECOME STRONG TO SEVERE WITH
GUSTY WINDS AND HAIL. STORMS WILL MOVE INTO THE CHAMPLAIN VALLEY
EARLY THIS AFTERNOON. HEAVY RAINFALL WILL ALSO ACCOMPANY THESE
