.DISCUSSION...
SKIES ARE PARTLY TO MOSTLY CLOUDY WITH LIGHT AND VARIABLE WINDS
ALONG THE FLORIDA KEYS. ANOTHER STEAMY AND VERY WARM EVENING IS
UNDERWAY WITH TEMPERATURES IN THE LOWER 80S AND DEW POINT READINGS
IN THE MID 70S. IN FACT...ITS HIGHLY LIKELY ANOTHER MAX/MIN RECORD
WILL BITE THE DUST WITH OUR TEMPERATURE NOT DROPPING BELOW 81
DEGREES. ONCE AGAIN...LOCAL RADARS ARE VOID OF PRECIPITATION ECHOES
IN OUR REGION. SURFACE WISE...A WESTERN ATLANTIC RIDGE EXTENDS
ACROSS THE SOUTH FLORIDA AND THE FLORIDA KEYS...WITH AN AREA OF
LOW PRESSURE (1003 MB) ON THE SOUTHWEST GULF OF MEXICO. ACROSS OUR
MARINE DISTRICT...WINDS ARE VARIABLE BUT LEANING TOWARD EAST
SOUTHEAST AT GENERALLY LESS THAN 10 KNOTS. OTHERWISE...OUR EVENING
SOUNDING REVEALS MOISTURE CONFINED TO BETWEEN (850 AND 800 MB) WITH
A 2 DEGREE INVERSION AT THE TOP OF THIS LAYER. WINDS VEER FROM EAST
SOUTHEAST TO SOUTHWEST...BEFORE INCREASING APPRECIABLY BEGINNING AT
850 MB.

.SHORT TERM (OVERNIGHT)...
OUR AREA WILL REMAIN ON THE WESTERN PERIPHERY OF A SHARP AND DEEP
ANTICYCLONIC FLOW FOR AT LEAST THE NEXT 18 HOURS.
MEANWHILE...EXPECT THE ISENTROPIC LIFT JUST BELOW THE 310 K SURFACE
TO SHUT DOWN LEAVING MAINLY PARTLY CLOUDY SKIES. LIGHT AND VARIABLE
WINDS WILL TURN SOUTHEAST TO SOUTH AND INCREASE TO 10 TO PERHAPS 15
MPH. WITH THAT SAID...SEE NO REASON TO STRAY FROM ONLY DIME POPS
WITH TEMPERATURES HOLDING NEAR 80 DEGREES.

WITH LOW PRESSURE IN THE SOUTHWEST GULF OF MEXICO MOVING EAST
NORTHEASTWARD...VARIABLE WINDS OF 5 TO 10 KNOTS SHOULD BECOMING

BASED AROUND 060 WILL ERODE BY SUNRISE. A CLOUD LINE BASED AT 020
WILL ONCE AGAIN FORM ALONG THE ISLAND CHAIN TOMORROW AFTERNOON. IN
ADDITION...EXPECT HAZY/SMOKEY SKIES EMANATING FROM CUBAN
AGRICULTURAL FIRES TO PERSIST....VISIBILITY REDUCTIONS NOT EXPECTED.
PRECIPITATION CHANCES FOR BOTH TERMINALS ARE LOW THROUGH TOMORROW
AFTERNOON.
