AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MIAMI FL
1025 AM EDT SAT JUN 6 2009

...STRONG TO SEVERE STORMS POSSIBLE THIS AFTERNOON INTERIOR AND
EAST COAST METRO AREAS...

.UPDATE...
THE MID TO UPPER LEVEL TROUGH OF LOW PRESSURE WAS LOCATED JUST
WEST OF SOUTH FLORIDA THIS MORNING. THIS TROUGH OF LOW PRESSURE
WILL REMAIN NEARLY STATIONARY TODAY...AS A UPPER LEVEL LOW CLOSES
OFF OVER THE BIG BEND AREA OF FLORIDA. THIS WILL KEEP THE STEERING
FLOW OVER THE CWA TODAY IN A SOUTHWEST DIRECTION. SO THE WEST
COAST SEA BREEZE SHOULD PUSH CROSS THE CWA TODAY...WHILE THE EAST
COAST SEA BREEZE REMAINS NEAR THE EAST COAST METRO AREAS.

AT THE SAME TIME...ANOTHER SHORT WAVE OVER THE EASTERN GULF OF
MEXICO SHOWN IN THE WATER VAPOR SATELLITE IMAGE WILL BE MOVING
THROUGH THE CWA THIS AFTERNOON. THIS SHORT WAVE WILL HELP TO FIRE
OFF SHOWERS AND THUNDERSTORMS OVER THE CWA LATE THIS MORNING INTO
THIS AFTERNOON OVER ALL OF THE CWA.

THE MIA MORNING SOUNDING IS ALSO SHOWING COOLER AIR IN THE MID
LEVELS THIS MORNING WITH -10.5C COMPARE TO YESTERDAY MORNING
READING AT -9.5C. THIS WILL ALLOW FOR SOME OF THE STORMS OVER THE
INTERIOR AND EAST COAST METRO AREAS TO BECOME STRONG TO SEVERE
THIS AFTERNOON INTO THIS EVENING...ESPECIALLY WHERE THE WEST AND
EAST COAST SEA BREEZES COLLIDE.

SO WILL CONTINUE THE STRONG TO SEVERE WORDING INTO THE HWO FOR THE
INTERIOR AND EAST COAST METRO AREAS...AND ADD THE HAIL WORDING TO
THE ZONES FOR THE INTERIOR AND EAST COAST METRO AREAS IN THE UPDATE.

THE SHOWER AND THUNDERSTORM ACTIVITY COULD CONTINUE INTO THIS
EVENING FOR THE EAST COAST METRO AREAS...UNTIL THE HEATING OF THE
DAY IS LOST. SO WILL UP THE POPS TO HIGH IN CHANCE CAT FOR THE
EAST COAST METRO AREAS THIS EVENING. THE WEST COAST METRO AREAS
SHOULD BE DRY THIS EVENING...BUT COULD SEE SOME MORE ACTIVITY LATE
TONIGHT INTO EARLY SUNDAY MORNING...DUE TO ANOTHER SHORT WAVE
WORKING IN FROM THE GULF OF MEXICO. SO WILL UP THE POPS TO CHANCE
CAT FOR LATE TONIGHT INTO EARLY SUNDAY MORNING FOR THE WEST COAST
METRO AREAS.

REST OF THE FORECAST LOOKS GOOD AT THIS TIME...AND NO OTHER
CHANGES ARE PLAN.

&&

.PREV DISCUSSION... /ISSUED 737 AM EDT SAT JUN 6 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...SO 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 07/00Z. SFC WINDS SHOULD REMAIN MAINLY
S-SW AOB 10 KTS THIS AFTERNOON AND EVENING.

&&

PREV DISCUSSION... /ISSUED 410 AM EDT SAT JUN 6 2009/

DISCUSSION...
ACTIVE CONVECTION CONTINUES ACROSS THE SOUTH FLORIDA PENINSULA AND
ADJACENT WATERS THIS MORNING. THE MID TO UPPER LEVEL TROUGH THAT
IS CURRENTLY DIGGING INTO THE EASTERN GULF CONTINUES TO DEEPEN AND
IS MOVING FURTHER SOUTH...WITH THE LATEST GUIDANCE FORECASTING THE
TROUGH TRANSITIONING BY TONIGHT TO A CLOSED LOW CENTERED OVER THE
NORTH FLORIDA PENINSULA AND THEN SLOWLY DRIFTING TO THE NORTHEAST
SUNDAY AND MONDAY.

FOR TODAY...ANTICIPATING ANOTHER ACTIVE DAY OF CONVECTION. THE
00Z SOUNDING INDICATED THE 500 MB TEMP NEAR -9 CELSIUS...WITH
FORECAST SOUNDING INDICATING IT COULD DROP TO ABOUT -10 CELSIUS TODAY.
IN ADDITION...THE FORECAST SOUNDING INDICATE THAT THE UPPER LEVEL
WINDS WILL REMAIN FAVORABLE FOR UPPER LEVEL DIVERGENCE AND AT THE
LOWER LEVELS MASS AND MOISTURE CONVERGENCE ARE EXPECTED. GIVEN ALL
THESE FACTORS NUMEROUS SHOWERS AND THUNDERSTORMS EXPECTED ACROSS
THE CWA TODAY...MAINLY OVER THE PENINSULA DURING THE AFTERNOON.
ONE INTERESTING FEATURE FROM THE GUIDANCE AND WATER VAPOR IMAGERY
SUGGESTS THAT SOME MID TO UPPER LEVEL DRIER AIR MAY WORK ITS WAY
ACROSS THE REGION BY THIS AFTERNOON. IF THIS PANS OUT THEN THE
HAIL POTENTIAL WOULD BE ENHANCED. BUT WITH THE ORIENTATION OF THE
UPPER LEVEL TROUGH THIS FEATURE IS NOT CERTAIN AS THERE IS STILL
CONSIDERABLE MID TO UPPER LEVEL MOISTURE ACROSS THE REGION.

ON SUNDAY AND INTO MONDAY...THE UPPER LEVEL LOW IS FORECAST TO
START TO DRIFT TO THE NORTHEAST...BUT THE REGION WILL LIKELY BE
AFFECTED BY A WEAK MID LEVEL TROUGH. THIS COMBINED WITH LOW LEVEL
SOUTHEASTERLY FLOW BRINGING LOW LEVEL MOISTURE ACROSS THE REGION WILL
CONTINUE TO RESULT IN AFTERNOON CONVECTION...BUT IS EXPECTED TO BE
MORE SCATTERED IN NATURE...WITH THIS TREND CONTINUING INTO MID WEEK.

MARINE...
MAINLY TRANQUIL MARINE CONDITIONS FORECAST FOR MOST OF THE FORECAST
PERIOD. BUT IN OR NEAR ANY THUNDERSTORMS WINDS AND SEAS CAN BE
LOCALLY MUCH HIGHER.

FIRE WEATHER...
NO FIRE WEATHER CONCERNS.
