AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MIAMI FL
1026 AM EDT SUN JUN 7 2009

...SOME STRONG TO SEVERE STORMS POSSIBLE INTERIOR AND EAST COAST
METRO AREAS TODAY INTO THIS EVENING...

.UPDATE...
THE MID TO UPPER LEVEL TROUGH WAS LOCATED ALONG THE I-4 CORRIDOR
THIS MORNING...AS TBW SOUNDING WAS SHOWING NORTHWEST FLOW AT 400
MBS ON UP...CAPE CANAVERAL SOUNDING WAS SHOWING WESTERLY WIND FLOW
AT 400 MBS ON UP...AND MIA SOUNDING STILL SHOWING SOUTHWEST WIND
FLOW THROUGH THE HOLD ATMOSPHERE.

THE LATEST SHORT RANGE MODELS ARE SHOWING THIS TROUGH OF LOW
PRESSURE TO MOVE EAST TODAY THROUGH SOUTH FLORIDA AND SHOULD BE
EAST OF THE CWA BY MONDAY MORNING. THIS WILL KEEP SOUTH FLORIDA
STILL IN A SOUTHWEST STEERING FLOW TODAY PUSHING THE WEST COAST
SEA BREEZE ACROSS THE CWA...WHILE KEEPING THE EAST COAST SEA
BREEZE NEAR THE EAST COAST METRO AREAS. SO HAVE LOWER THE POPS TO
CHANCE CAT FOR THE WEST COAST METRO AREAS WHILE KEEPING THE
NUMEROUS POPS UP FOR THE EAST COAST METRO AREAS.

THE MIA MORNING SOUNDING WAS ALSO SHOWING THE 500 MB TEMPS AROUND
-10C THIS MORNING WHICH COULD ALLOW FOR SOME OF THE STORMS TO
BECOME STRONG TO SEVERE WITH HAIL...GUSTY WINDS...HEAVY
RAINFALL...AND FREQUENT LIGHTNING STRIKES TO OCCUR WITH SOME OF
THE STORMS. SO WILL CONTINUE TO MENTION THIS IN THE HWO AND IN THE
ZONES FOR THE INTERIOR AND EAST COAST METRO AREAS FOR TODAY INTO
THIS EVENING.

THE MARINE PACKAGE LOOKS GOOD FOR TODAY INTO TONIGHT. SO NO
CHANGES TO THE MARINE PACKAGE IN THE MORNING UPDATE.

NO CHANGES ARE PLAN FOR REST OF THE ZONES AND MARINE PACKAGE AT
THIS TIME.

&&
.UPDATE...54/BNB

.PREV DISCUSSION... /ISSUED 732 AM EDT SUN JUN 7 2009/

AVIATION...ALL THE TERMINALS SHOULD CONTINUE WITH MOSTLY VFR
CONDITIONS THROUGH THE MORNING HOURS. A MOIST UNSTABLE AIRMASS
WILL CONTINUE OVER THE LOCAL AREA...THEREFORE, SHWRS/TSTMS ARE
EXPECTED AGAIN TODAY INITIALLY OVER INLAND AREAS BUT THEN BEING
STEERED EASTWARD BY THE AIR FLOW ALOFT. WL INDICATE VCTS OVR ALL
TERMINALS FROM 14Z THROUGH AT LEAST 08/02Z. IF TSTMS DEVELOP EARLY
WILL NEED TO AMEND TO ADD TEMPOS AND MOST LIKELY WILL BE IN THE
18Z TAFS FOR THE EAST COAST TERMINALS. SFC WINDS SHOULD REMAIN
MAINLY SW AOB 10 KTS THIS AFTERNOON AND EVENING EXCEPT FOR A SE
AFTN SEABREEZE EAST COAST.

PREV DISCUSSION... /ISSUED 445 AM EDT SUN JUN 7 2009/

DISCUSSION...

THE MID TO UPPER LEVEL TROUGH REMAINS ENTRENCHED ACROSS THE EASTERN
GULF AND WILL CONTINUE TO EXERT ITS INFLUENCE ACROSS SOUTH FLORIDA
AND ADJACENT WATERS. CAN EXPECT ANOTHER ROUND OF ACTIVE
CONVECTION THIS AFTERNOON. IN ADDITION TO THE AFOREMENTIONED MID
TO UPPER LEVEL TROUGH...LATEST GUIDANCE INDICATES SYNOPTIC SCALE
LARGE SCALE ASCENT ACROSS THE REGION BY THIS AFTERNOON...WITH
MOISTURE LIKELY EXTENDING THROUGH THE COLUMN WITH PWATS NEAR TWO
INCHES POSSIBLE...ALTHOUGH RECENT WATER VAPOR IMAGERY INDICATES SOME
DRIER AIR MAY MAKE INTO THE MID TO UPPER LEVELS. BUT GIVEN
PROXIMITY OF LOW TO THE SOUTH FLORIDA PENINSULA VERY HARD TO KNOW
IF THE DRIER AIR MAY MAKE IT THIS FAR SOUTH. AT ANY
RATE...ACTIVE CONVECTION ACROSS THE REGION IS EXPECTED AGAIN
TODAY WITH A 70 POP FORECAST FOR MOST OF THE PENINSULA...WITH
LOCALLY HEAVY RAINFALL EXPECTED AND SOME STRONG THUNDERSTORMS
POSSIBLE. HAIL AND STRONG WINDS ARE POSSIBLE WITH THE OCCURRENCE
OF THE THUNDERSTORMS.

LATEST SUITE OF GUIDANCE CONTINUES TO SUGGEST THAT THE MID TO
UPPER LEVEL TROUGH IS STILL EXPECTED TO SLOWLY DRIFT EASTWARD
BEGINNING MONDAY...AND BY WEDNESDAY AN UPPER LEVEL RIDGE MAY BEGIN
TO DEVELOP ACROSS THE REGION. SO AFTER TODAY...SCATTERED
MAINLY AFTERNOON SHOWERS AND THUNDERSTORMS ACROSS THE PENINSULA IS
FORECAST...BUT WILL ULTIMATELY DEPEND ON THE UPPER LEVEL TROUGH
BEING NUDGED EASTWARD BY AN UPPER LEVEL RIDGE DEVELOPING OVER THE
NORTHWEST GULF.

NEED TO STRESS THE UNCERTAINTY IN THE WIND FORECAST...BOTH IN THE
SHORT TERM AND LONG TERM PORTIONS OF THE FORECAST. THE GUIDANCE
WAS NOT CONSISTENT...AND USED SOME OF THE SHORT RANGE ENSEMBLE
FORECAST WINDS TO GIVE A BETTER DEPICTION OF THE WIND FIELD FOR
THE SHORT TERM. FOR THE LONG TERM THERE IS ALSO A LOT OF
UNCERTAINTY IN THE FORECAST...WITH THE SUITE OF GUIDANCE
DEVELOPING AN AREA OF LOW PRESSURE IN THE WESTERN
CARIBBEAN IN THE EXTENDED PERIODS...WHICH INFLUENCES THE LOCAL
PRESSURE GRADIENT AND WIND FORECAST ACROSS THE REGION. WILL HAVE
TO WAIT AND SEE IF THIS REMAINS A PERSISTENT FEATURE IN THE
GUIDANCE OVER THE NEXT FEW DAYS.

MARINE...
MAINLY TRANQUIL SEAS EXPECTED FOR THE MAJORITY OF THE FORECAST
PERIOD. BUT NEED TO STRESS THE UNCERTAINTY IN THE WIND
FORECAST...ESPECIALLY IN THE LATER PERIODS OF THE FORECAST.

FIRE WEATHER...
NO FIRE WEATHER CONCERNS.
