.UPDATE...

.UPDATE...

EXCEPT FOR SOME LINGERING LIGHT SHOWERS...CONVECTION HAS MOSTLY
SUBSIDED THIS EVENING. HOWEVER...THERED IS STILL A CHANCE OF
ADDITIONAL SHOWERS OR THUNDERSTORMS OVER NIGHT ESPECIALLY ACROSS
THE ATLANTIC WATERS. AN UPPER LEVEL TROUGH OFF THE SOUTHEAST U.S.
COAST AND EAST OF THE FLORID PENINSULA COULD HELP TO INITIATE
FURTHER CONVECTION OVER NIGHT ACROSS THE ATLANTIC WATERS AND COULD
AFFECT THE EAST COAST METRO AREAS AS WELL. THE LATEST WATER VAPOR
IMAGERY INDICATES THE PRESENCE OF THE UPPER LEVEL TROUGH.

DISCUSSION...

STORMS HAVE BEEN ANCHORED ALONG THE EAST COAST THIS
AFTERNOON...WITH OUTFLOW BOUNDARIES POSSIBLY LEADING TO ADDITIONAL
DEVELOPMENT FURTHER INLAND LATE THIS PM. NEARLY STATIONARY STORMS
HAVE ALREADY LED TO STREET FLOODING THROUGH SOME OF THE MORE
SUSCEPTIBLE AREAS ALONG THE BEACH.

AN UPPER LEVEL DISTURBANCE...WHICH LEAD TO NUMEROUS THUNDERSTORMS
WELL OFF THE EAST COAST THIS MORNING...WILL SLOWLY MOVE WEST
TONIGHT. THIS MAY LEAD TO ADDITIONAL STORMS DEVELOPING LATE IN OUR
EASTERN OFFSHORE ZONES AFTER MIDNIGHT. THE PROXIMITY OF THIS
DISTURBANCE TO THE EAST COAST WILL AID THUNDERSTORM DEVELOPMENT ON
THURSDAY. MUCH DRIER AIR ASSOCIATED WITH A SAHARAN DRY LAYER IS
STILL EXPECTED TO ARRIVE ON FRIDAY...LIMITING COVERAGE OF STORMS.
PERSISTENT EASTERLY FLOW IS EXPECTED TO ARRIVE THIS WEEKEND...WITH
MORNING PRECIP IN THE COASTAL WATERS...WITH STORMS THEN SHIFTING
TO THE GULF COAST LATER IN THE DAY.

AVIATION...

CONVECTION IS GETTING ORGANIZED ALONG THE EAST AND WEST COAST SEA
BREEZES. THE EAST COAST SEA BREEZE IS ALMOST LOCATED AT THE
COASTLINE WITH CONVECTION BUILDING WESTWARD. INTRODUCED TEMPO TSRA
FOR ALL EAST COAST TERMINALS UNTIL 21Z AND THEN TRANSITIONED TO VCTS
UNTIL 00Z. FOR APF INCLUDED VCTS FOR THIS AFTERNOON/EVENING SINCE
THE SEA BREEZE HAS PENETRATED INLAND ALREADY AND THE ACTIVITY OVER
THE GULF WATERS HAS DIMINISHED.

MARINE...

THE WINDS WILL CONTINUE TO BE LIGHT BEFORE EASTERLY WINDS DEVELOP
THIS WEEKEND. SEAS WILL BE 2 FEET OR LESS IN BOTH THE ATLANTIC
AND GULF WATERS OF SOUTH FLORIDA THROUGH END OF THIS WEEK.
THEREFORE...BOATING CONDITIONS SHOULD BE GOOD OUTSIDE OF ANY
SHOWERS OR THUNDERSTORMS THIS WEEK OVER THE SOUTH FLORIDA WATERS.
