AREA FORECAST DISCUSSION

.DISCUSSION...
AS OF 18Z THIS AFTERNOON...FAR LESS ACTIVITY IS SEEN ON RADAR THAN
AT THIS POINT YESTERDAY. EASTERLY SEA BREEZE HAS BEEN SLOW GETTING
GOING BUT SEEMS TO BE PUSHING INLAND A BIT ATTM. STILL BELIEVE
CONVECTION WILL INCREASE IN COVERAGE THROUGH THE REMAINDER OF THE
AFTERNOON MAINLY ACROSS THE EAST COAST COUNTIES. A FEW STORMS
COULD AGAIN BE STRONG WITH GUSTY WINDS...HEAVY DOWNPOURS...AND
LIGHTNING STRIKES BEING THE MAIN THREATS. ACTIVITY SHOULD THEN
DIMINISH BY EARLY EVENING WITH LOSS OF HEATING.

SUNDAY INTO MONDAY...BETTER MID LEVEL DRYING WILL TAKE PLACE AS AN
H5 RIDGE CENTERS ACROSS THE FLORIDA STRAITS. A SURFACE RIDGE OFF
THE ATLANTIC COAST WILL THEN BUILD BACK TO THE WEST SLIGHTLY
WHICH WILL ALLOW A QUASI-STATIONARY FRONTAL BOUNDARY TO EASE BACK
NEAR SOUTH FLORIDA AS A BACK DOOR COLD FRONT. WITH THIS FEATURE IN
THE AREA COMBINED WITH DIURNAL HEATING...BELIEVE CHANCES FOR
SHOWERS AND THUNDERSTORMS WILL CONTINUE EACH DAY WITH SLIGHTLY
BETTER CHANCES SUNDAY AFTERNOON DUE MAINLY TO THE PROXIMITY OF THE
FRONT.

A SLOW MOVING H5 SHORTWAVE WILL BEGIN TO DIG INTO THE NORTHERN
PORTIONS OF FLORIDA BY TUESDAY. AS IT DOES...AN ASSOCIATED COLD
FRONT WILL INCH CLOSER TO THE AREA ENHANCING CHANCES FOR SHOWERS
AND THUNDERSTORMS TUESDAY AND WEDNESDAY. WITH WEAK STEERING FLOW
THE SHORTWAVE WILL STRUGGLE TO CONSOLIDATE AND EXIT INTO THE
ATLANTIC. AS A RESULT...WEAK MID LEVEL DISTURBANCES EMBEDDED IN
THE FLOW WILL SWING BY JUST NORTH OF THE AREA KEEPING CHANCES OF
SHOWERS AND THUNDERSTORMS THROUGH THE REMAINDER OF THE WEEK.

&&

.AVIATION...
HEAVY CLOUD COVER EARLIER THIS MORNING HELD BACK DIURNAL HEATING
CYCLE AND TCU JUST BEGINNING TO DEVELOP ACROSS S FL AT 17Z. SHORT
TERM MODELS HAVE ALSO BECOME LESS CONFIDENT OF CONVECTION
INITIATION PRIOR TO AROUND 18-19Z SO DELAYED VCTS IN THE TAFS FOR
THESE REASONS. ALSO TOOK OUT MENTION OF THEM FOR THE KTMB TERMINAL
AS THE CELLS SHOULD BE WELL NORTH AS THE AFTERNOON PROGRESSES AND
COULD EVEN BE NORTH OF THE KMIA AND KOPF TERMINALS. LIGHT FLOW HAS
ALLOWED SEA BREEZES ALONG BOTH COASTS AND THIS WILL CONTINUE UNTIL
AROUND 00-01Z THIS EVENING.

&&

.MARINE...
EASTERLY WINDS WILL REMAIN BELOW 15 KNOTS THROUGH THIS WEEKEND
OVER ALL THE LOCAL WATERS. THE SEAS WILL ALSO REMAIN AT 3 FEET OR
LESS OVER BOTH THE ATLANTIC AND GULF WATERS THROUGH THIS WEEKEND.
SO BOATING CONDITIONS SHOULD BE GOOD OUTSIDE OF ANY SHOWERS OR
THUNDERSTORMS THIS WEEKEND.

&&

.FIRE WEATHER...
MINIMUM RELATIVE HUMIDITIES WILL REMAIN WELL ABOVE CRITICAL LEVELS
ACROSS SOUTH FLORIDA THROUGH THE WEEKEND.
