AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MIAMI FL
946 AM EDT TUE JUN 2 2009

.UPDATE...
THE MIA MORNING SOUNDING WAS SHOWING A 850 TO 700 MB RIDGE OVER
SOUTH FLORIDA. THIS RIDGE WILL REMAIN IN PLACE TODAY BEFORE
SHIFTING NORTHWARD TONIGHT INTO CENTRAL FLORIDA. THIS WILL ALLOW
FOR THE STEERING FLOW TO BE LIGHT FROM THE SOUTH TO SOUTHWEST OVER
THE CWA. AT THE SAME TIME...BOTH THE EAST AND WEST COAST SEA
BREEZES SHOULD DEVELOP AND PUSH INLAND TODAY. SO HAVE FOCUS THE
HIGHEST POPS OVER THE INTERIOR AREAS OF THE CWA THIS AFTERNOON.
HOWEVER...ALL AREAS OF THE CWA WILL SEE A CHANCE FOR SHOWERS AND
THUNDERSTORMS AS THE PWAT VALUES ARE STILL RUNNING AROUND 1.7 TO
1.8 INCHES THIS MORNING AND THE CAPE IS AROUND 4000 J/KG.

ONE OR TWO OF THE STORMS COULD EVEN BE STRONG AGAIN OVER THE CWA
ESPECIALLY OVER THE INTERIOR AREAS WHERE THE SEA BREEZES AND LAKE
BREEZE BOUNDARIES COLLIDE. THE PRIMARY IMPACTS FROM THE STORMS
WILL BE HAIL...GUSTY WINDS...LIGHTNING STRIKES...AND LOCALLY HEAVY
RAINFALL. SO WILL MENTION THIS IN THE MORNING HWO UPDATE.

THE OTHER CHANGE IN THE FORECAST TO KEEP THE SLIGHT CHANCE OF
SHOWERS AND THUNDERSTORMS GOING FOR THE EAST COAST METRO AREAS
TONIGHT DUE TO THE SOUTHEAST WIND FLOW.

REST OF THE FORECAST LOOKS GOOD AT THIS TIME AND NO OTHER CHANGE
AREA PLAN.

FLOW ALOFT. ATLANTIC COAST SEA BREEZE SHOULD BEGIN TO PUSH INLAND
DURING THE MID/LATE MORNING...AND WILL INTRODUCE VCTS/CB AT 15Z.
LIGHT ENELY STEERING FLOW SHOULD ALLOW CONVECTIVE ACTIVITY TO SLOWLY
DEVELOP/SPREAD WESTWARD TOWARD THE INTERIOR AND GULF COAST...WITH
IMPROVING CONDITIONS FOR THE ATLANTIC COAST AFTER 19Z. HOWEVER...AT
APF...WILL CARRY VCTS/CB THROUGH 03/02Z WITH LINGERING LIGHT SHRA

PERIOD. PREVAILING WINDS WILL REMAIN FROM THE SE/ESE AT 5-10 KNOTS
