...WETTER PATTERN SETTING UP FOR THE EAST COAST AREAS THIS WEEKEND
INTO EARLY NEXT WEEK...

.DISCUSSION...
THE EAST AND WEST COAST SEA BREEZES WERE DEVELOPING ALONG BOTH
COASTS EARLY THIS AFTERNOON WITH ISOLATED SHOWERS AND THUNDERSTORMS
ALONG THE SEA BREEZES. THE EAST COAST SEA BREEZE WILL MOVE WEST
ACROSS SOUTH FLORIDA THIS AFTERNOON...WHILE THE WEST COAST SEA
BREEZE REMAINS NEAR THE WEST COAST. SO THE SHOWERS AND
THUNDERSTORMS THAT DEVELOP THIS AFTERNOON WILL BE MAINLY OVER THE
INTERIOR AND WEST COAST METRO AREAS. HOWEVER...THERE COULD BE A
FEW SHOWERS THAT COULD MOVE INTO THE EAST COAST METRO AREAS THIS
AFTERNOON ON THE EASTERLY WIND FLOW FROM THE ATLANTIC WATERS. SO
WILL CONTINUE WITH THE HIGHEST POPS OVER THE INTERIOR AND WEST
COAST METRO AREAS TAPERING DOWN TO ISOLATED OVER THE EAST COAST
METRO AREAS FOR THIS AFTERNOON.

THE SHOWERS AND THUNDERSTORMS SHOULD DISSIPATE THIS EVENING OVER
SOUTH FLORIDA AS THE HEATING OF THE DAY IS LOST. SO WILL KEEP THE
CHANCE POPS FOR THE INTERIOR AND WEST COAST METRO AREAS FOR THE
EVENING HOURS. HOWEVER...THE WINDS WILL REMAIN EASTERLY TONIGHT
DUE TO HIGH PRESSURE OVER CENTRAL FLORIDA. THIS WILL ALLOW FOR A
FEW SHOWERS OVER THE ATLANTIC WATERS TO WORK INTO THE EAST COAST
METRO AREAS BEFORE DISSIPATING. SO WILL KEEP A SLIGHT CHANCE OF
POPS FOR THE EAST COAST METRO AREAS FOR TONIGHT.

THE RIDGE OF HIGH PRESSURE OVER CENTRAL FLORIDA WILL MOVE INTO
SOUTH FLORIDA ON THURSDAY...BEFORE CONTINUING TO MOVE SOUTH INTO
THE FLORIDA KEYS ON FRIDAY INTO THIS WEEKEND...AS A COLD FRONT
OVER THE TENNESSEE VALLEY MOVES SOUTH INTO NORTHERN CENTRAL
FLORIDA. THIS WILL ALLOW FOR THE STEERING FLOW OVER THE CWA TO BE
SOUTHERLY ON THURSDAY...BEFORE GOING SOUTHWEST ON FRIDAY INTO THIS
WEEKEND. SO THE FOCUS OF THE SHOWER AND THUNDERSTORM ACTIVITY
SHOULD BE AROUND LAKE OKEECHOBEE ON THURSDAY...BEFORE SHIFTING TO
THE EAST COAST METRO AREAS ON FRIDAY INTO THIS WEEKEND.

THE UPPER LEVEL LOW JUST EAST OF THE BAHAMA ISLANDS WILL ALSO MOVE
TO THE NORTHWEST TO NORTH AND AWAY FROM SOUTH FLORIDA BY FRIDAY.
HOWEVER...WITH THE UPPER LEVEL LOW CLOSE BY...THE MID TO UPPER
LEVELS OF THE ATMOSPHERE WILL BE A LITTLE BIT COOL THROUGH FRIDAY.
SO A FEW OF THE STORMS COULD BE STRONG ESPECIALLY WERE THE LAKE
AND SEA BREEZES COLLIDE ON BOTH DAYS. SO WILL MENTION THIS IN THE
EVENING HWO UPDATE.

.EXTENDED FORECAST...
THE RIDGE OF HIGH PRESSURE WILL REMAIN OVER THE FLORIDA KEYS EARLY
TO MIDDLE OF NEXT WEEK...AS THE UNUSUALLY DEEP TROUGH OF LOW
PRESSURE REMAINS OVER THE EASTERN UNITED STATES. A THE SAME
TIME...THE WEAK COLD FRONT WILL ALSO WASH OUT OVER SOUTH CENTRAL
FLORIDA OR AROUND LAKE OKEECHOBEE. THIS WILL KEEP SOUTH FLORIDA
IN A SOUTHWEST STEERING FLOW ALLOWING FOR THE HIGHEST POPS TO BE
OVER THE EAST COAST METRO AREAS EACH DAY.

&&

.MARINE...
THE WINDS WILL BE EASTERLY TONIGHT BEFORE SHIFTING SLOWLY TO A
SOUTHWEST DIRECTION BY FRIDAY...AND REMAINING THERE THROUGH THIS
WEEKEND INTO EARLY NEXT WEEK. THE SPEEDS WILL ALSO REMAIN BELOW 10
KNOTS THROUGH FRIDAY...BEFORE INCREASING TO 10 TO 15 KNOTS THIS
WEEKEND. HOWEVER...THE SEAS WILL STILL REMAIN BELOW 6 FEET THROUGH
EARLY NEXT WEEK FOR THE ATLANTIC AND GULF WATERS. THEREFORE...BOATING
SHOULD BE GOOD OUTSIDE OF THE SHOWERS AND THUNDERSTORMS REST OF
THIS WEEK INTO THIS WEEKEND.

&&

.FIRE WEATHER...
THE RELATIVE HUMIDITIES COULD FALL INTO THE 40S OVER THE EAST
COAST AREAS ON FRIDAY INTO THIS WEEKEND...BUT SHOULD REMAIN ABOVE
THE 35 PERCENT CRITICAL VALUE. SO NO PROBLEMS ARE EXPECTED AT THIS
TIME WITH THE FIRE WEATHER THROUGH THE WEEKEND.
