AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
214 PM EDT TUE MAY 26 2009

...HIGHEST RAIN CHANCE CONTINUES FOR THE EAST COAST METRO AREAS THIS
WEEK...

.DISCUSSION...
THE EAST AND WEST COAST SEA BREEZES HAS DEVELOPED EARLY THIS
AFTERNOON WITH SHOWERS AND THUNDERSTORMS ALONG THE SEA BREEZES.
THE WEST COAST SEA BREEZE WILL CONTINUE TO MOVE EAST ACROSS SOUTH
FLORIDA THIS AFTERNOON..WHILE THE EAST COAST SEA BREEZE REMAINS
OVER THE EAST COAST METRO AREAS...DUE TO THE SOUTHWEST STEERING
FLOW. THIS MEANS THAT THE INTERIOR AND EAST COAST METRO AREAS
WILL CONTINUE TO SEE THE SHOWERS AND THUNDERSTORMS INCREASE IN
COVERAGE...WHILE THE WEST COAST AREAS WILL BE MOSTLY DRY THIS
AFTERNOON. SO WILL CONTINUE THE SCATTERED TO NUMEROUS POPS OVER
THE INTERIOR AND EAST COAST METRO AREAS FOR THIS AFTERNOON...WHILE
LOWERING THE POPS TO SLIGHT CHANCE FOR THE WEST COAST METRO AREAS.

AT THE SAME TIME...A SHORT WAVE IN THE MID TO UPPER LEVELS OF THE
ATMOSPHERE OVER THE EASTERN GULF OF MEXICO WILL MOVE EAST THROUGH
SOUTH FLORIDA THIS AFTERNOON INTO THIS EVENING. THIS SHORT WAVE
WILL KEEP THE MID TO UPPER LEVELS COOL...AND ALLOW FOR THE
STRONGEST STORMS TO PRODUCE HAIL...GUSTY WINDS...AND HEAVY
RAINFALL. SO WILL MENTION A FEW STRONG STORMS ALONG THE EAST COAST
METRO AREAS FOR THIS AFTERNOON INTO EARLY EVENING.

THE SHOWERS AND THUNDERSTORMS SHOULD DIE OUT SLOWLY THIS EVENING
OVER THE INTERIOR AND EAST COAST METRO AREAS AS THE HEATING OF THE
DAY IS LOST. THE WEST COAST METRO AREAS COULD SEE A FEW SHOWERS OR
THUNDERSTORMS OVERNIGHT...DUE TO THE LIGHT SOUTHWEST WIND FLOW
OVER THE CWA.

THE RIDGE OF HIGH PRESSURE OVER FLORIDA KEYS WILL REMAIN NEARLY
STATIONARY THROUGH END OF THIS WEEK. THIS WILL KEEP THE CWA IN A
SOUTHWEST STEERING FLOW WHICH WILL FOCUS THE HIGHEST POPS OVER THE
EAST COAST METRO AREAS EACH DAY. SO HAVE GONE WITH SCATTERED TO
NUMEROUS POPS ALONG THE EAST COAST METRO AREAS TAPERING DOWN TO
LOW END SCATTERED POPS ALONG THE WEST COAST METRO AREAS.

THERE IS ALSO ANOTHER SHORT WAVE OVER THE CENTRAL GULF OF MEXICO
SEEN IN THE WATER VAPOR IMAGERY THAT WILL ALSO MOVE EAST AND INTO
SOUTH FLORIDA ON WEDNESDAY WHICH WILL KEEP THE COOL AIR ALOFT IN
PLACE. SO WILL CONTINUE TO MENTION A FEW STRONG STORMS WITH GUSTY
WINDS...HAIL...AND LOCALLY HEAVY RAINFALL IN THE HWO FOR WEDNESDAY.

TEMPERATURES EACH DAY THIS WEEK WILL BE AROUND 90 OVER THE EAST
COAST METRO AREAS TAPERING DOWN TO THE MID 80S OVER THE WEST COAST
METRO AREAS FOR THE HIGHS. THE LOWS WILL BE IN THE LOWER TO MID
70S OVER THE METRO AREAS WITH MID TO UPPER 60S OVER THE INTERIOR
AREAS EACH NIGHT THIS WEEK.

.EXTENDED FORECAST...
A WEAK COLD FRONT WILL WORK INTO SOUTH FLORIDA FROM THE NORTH THIS
WEEKEND BEFORE WASHING OUT. HIGH PRESSURE WILL THEN BUILD BACK
INTO SOUTH FLORIDA EARLY NEXT WEEK FROM THE ATLANTIC WATERS. THIS
PATTERN WILL BRING IN A LITTLE BIT OF DRIER AIR TO THE CWA THIS
WEEKEND. IT WILL ALSO REFOCUS THE HIGHEST POPS FROM THE EAST
COAST METRO AREAS EARLY THIS WEEKEND TO THE WEST COAST METRO
AREAS BY EARLY NEXT WEEK. SO HAVE KEPT THE 20 TO 30 PERCENT POPS
OVER THE CWA THIS WEEKEND...AND THEN PUT HAVE THE HIGHEST POPS OVER
THE WESTERN AREAS EARLY NEXT WEEK.

&&

.MARINE...
THE WINDS WILL BE FROM THE SOUTH TO SOUTHWEST DIRECTION TONIGHT
THROUGH EARLY THIS WEEKEND...BEFORE SWINGING TO A SOUTHEAST
DIRECTION BY END OF THIS WEEKEND. THE SPEEDS WILL ALSO REMAIN
BELOW 15 KNOTS THROUGH THIS WEEKEND. THE SEAS WILL ALSO BE 2 FEET
OR LESS THROUGH THE WEEKEND.

SO BOATING CONDITIONS SHOULD BE GOOD OUTSIDE OF THE SHOWERS AND
THUNDERSTORMS...AS THERE WILL BE NO HEADLINES IN EFFECT FOR ALL OF
THE SOUTH FLORIDA WATERS.

&&

.FIRE WEATHER...
THE RELATIVE HUMIDITIES WILL ALSO REMAIN WELL ABOVE CRITICAL VALUE
OVER ALL OF SOUTH FLORIDA THIS WEEK. SO NO PROBLEMS WITH THE FIRE
WEATHER THIS WEEK.
