NATIONAL WEATHER SERVICE MIAMI FL
409 PM EDT TUE MAR 29 2011

.UPDATE...
SHOWERS AND THUNDERSTORMS HAVE DEVELOP OVER THE INTERIOR AREAS OF
MIAMI-DADE AND BROWARD COUNTIES THIS AFTERNOON. THESE STORMS WILL

.PREV DISCUSSION... /ISSUED 238 PM EDT TUE MAR 29 2011/

..POSSIBLE STRONG STORMS ON THURSDAY FOR SOUTH FLORIDA...

DISCUSSION...
THE STATIONARY FRONT WILL CONTINUE TO DISSIPATE THIS AFTERNOON
OVER CENTRAL FLORIDA. THIS WILL KEEP THE STEERING FLOW OVER THE
CWA IN A SOUTH TO SOUTHWEST DIRECTION AND ALLOW FOR THE ISOLATED
TO SCATTERED SHOWERS AND THUNDERSTORMS THAT DO DEVELOP OVER THE
INTERIOR AREAS TO PUSH NORTH TO NORTHEAST AND TOWARDS THE LAKE
OKEECHOBEE AND EASTERN SECTIONS OF SOUTH FLORIDA THIS AFTERNOON
INTO THIS EVENING. SO WILL CONTINUE THE CHANCE POPS FOR THE AREA
THROUGH THIS AFTERNOON WITH THE HIGHEST POPS OVER THE LAKE
OKEECHOBEE AND NORTHEAST PORTIONS OF THE CWA.

THE SHOWERS AND THUNDERSTORMS SHOULD END OVER THE CWA THIS EVENING
AS THE HEATING OF THE DAY IS LOST. HOWEVER...THE WINDS WILL
BECOMING AROUND TO THE SOUTHEAST DIRECTION AS HIGH PRESSURE BUILDS
OVER THE CWA FROM THE FLORIDA KEYS. SO THIS WILL ALLOW FOR A FEW
SHOWER TO WORK INTO THE EAST COAST METRO AREAS DURING THE
OVERNIGHT HOURS. SO WILL END THE SHOWER AND THUNDERSTORM THREAT
FOR MOST AREAS BY MIDNIGHT NIGHT...WITH THE EAST COAST AREAS SEE
SLIGHT CHANCE OF SHOWERS AFTER MIDNIGHT. THERE COULD ALSO BE SOME
FOG FORMATION OVER THE INTERIOR AND WEST COAST AREAS LATE
TONIGHT...DUE TO THE LOW LEVEL MOISTURE IN PLACE ALONG WITH THE
LIGHT WINDS.

WEDNESDAY INTO THURSDAY...
THE HIGH WILL REMAIN OVER SOUTH FLORIDA ON WEDNESDAY BEFORE
GETTING PUSH EAST INTO THE ATLANTIC WATERS WEDNESDAY NIGHT INTO
THURSDAY...AS A TROUGH OF LOW PRESSURE MOVES EAST FROM THE CENTRAL
PLAIN STATES INTO THE EASTERN US. THIS WILL ALLOW FOR A COLD FRONT
TO WORK INTO CENTRAL FLORIDA ON THURSDAY...AND ALLOW FOR THE
STEERING FLOW TO SWING FROM A SOUTHEAST DIRECTION WEDNESDAY TO A
SOUTHWEST DIRECTION ON THURSDAY WHILE BECOMING BREEZY BY THURSDAY
OVER THE CWA.

THIS BREEZY SOUTHWEST STEERING FLOW WILL ALLOW FOR TEMPERATURES TO
WARM UP TO NEAR RECORD HIGHS OVER THE EAST COAST METRO AREAS ON
THURSDAY. MORE ON THIS IN THE CLIMATE SECTION BELOW.

AT THE SAME TIME...A MID TO UPPER LEVEL JET OF 100 TO 130 KNOTS
WILL BE MOVING THROUGH CENTRAL FLORIDA WITH A LOW TO MID LEVEL JET
OF 40 TO 50 KNOTS WORKING THROUGH SOUTH CENTRAL FLORIDA. THIS WILL
ALLOW FOR THUNDERSTORMS TO DEVELOP AHEAD OF THE FRONT OVER SOUTH
FLORIDA WHERE SOME OF THEM COULD BECOME STRONG. THE STORM
PREDICTION CENTER HAS ALSO PUT THE NORTHERN AREAS OF THE CWA IN A
SLIGHT RISK OF SEVERE WEATHER FOR THURSDAY. SO WILL MENTION THIS
IN THE HWO AFTERNOON PACKAGE FOR THURSDAY. IF THIS TREND CONTINUES
IN LATER FORECAST THEN THE POSSIBILITY OF STRONG OR EVEN SEVERE
WORDING WILL BE NEEDED IN THE ZONES FOR THURSDAY IN LATER FORECAST
PACKAGES.

EXTENDED FORECAST...
ONCE THE FRONT CLEAR SOUTH FLORIDA ON FRIDAY...HIGH PRESSURE WILL
THEN BUILD BACK INTO THE AREA FROM THE NORTH FOR THIS WEEKEND INTO
EARLY NEXT WEEK. THIS WILL BRING BACK THE DRY WEATHER TO THE AREA
FOR THIS WEEKEND INTO EARLY NEXT WEEK.

MARINE...
THE WINDS WILL CONTINUE TO SOUTHERLY THIS AFTERNOON BEFORE
BACKING TO A SOUTHEAST DIRECTION LATE TONIGHT INTO WEDNESDAY. THE
WINDS WILL THEN SWING TO A SOUTHWEST DIRECTION ON THURSDAY AHEAD
OF A COLD FRONT. THE SPEEDS WILL BE LESS THAN 15 KNOTS TONIGHT
THROUGH WEDNESDAY NIGHT...BEFORE INCREASING INTO 15 TO 20 KNOTS ON
THURSDAY OVER ALL OF THE CWA WATERS. THIS WILL KEEP THE SEAS BELOW
6 FEET THROUGH THURSDAY. SO BOATING CONDITIONS SHOULD BE GOOD
OUTSIDE OF ANY SHOWERS OR THUNDERSTORMS. SOME OF THE THUNDERSTORMS
COULD EVEN BE STRONG ON THURSDAY OVER THE CWA WATERS.

FIRE WEATHER...
THE RELATIVE HUMIDITIES WILL REMAIN ABOVE 35 PERCENT ON WEDNESDAY
INTO THURSDAY OVER SOUTH FLORIDA...BUT COULD FALL DOWN INTO THE
UPPER 30S ON THURSDAY OVER THE EAST COAST METRO AREAS. SO AT THIS
TIME DO NO EXPECT ANY PROBLEMS IN THE FIRE WEATHER THROUGH
THURSDAY.

CLIMATE...
THE HIGHS ON THURSDAY SHOULD BE ABLE TO GET UP TO AROUND 90
DEGREES ALONG THE EASTERN AREAS OF THE CWA...DUE TO THE SOUTHWEST
BREEZY WINDS. HERE ARE THE FORECAST HIGHS AND RECORD HIGHS FOR
THURSDAY:
