THE COMBINATION OF DAY TIME HEATING AND THE KEYS BEING POSITIONED
WITHIN THE WESTERN REACHES OF AN ATLANTIC SURFACE RIDGE HAS
RESULTED IN LIGHT AND VARIABLE BREEZES. THE KEYS REMAIN EMBEDDED
WITHIN THE NORTHERN FLANK OF DEEP LAYERED RIDGING, KEEPING
PRECIPITABLE WATER AROUND .5 INCHES. THE SHALLOW BOUNDARY LAYER
FLOW HAS BEEN LIGHT SOUTHERLY AND RESULTED IN A CUBAN INHIBITION
LAYER BASED DOWN AROUND 970 MB. THIS HAS LED TO CLEAR SKIES.
TEMPERATURES ARE SLOWLY FALLING AND ARE BROADLY IN THE UPPER 60S
WITH DEW POINTS IN THE MID TO UPPER 60S.
WINDS SHOULD GRADUALLY BECOME PREVAILING LIGHT SOUTHERLIES AS THE
MAINLAND COOLS, THE SURFACE RIDGE RETREATS TO THE EAST, AND
SURFACE TROUGHING MOVE INTO THE GULF. UNTIL BREEZES FIRM UP, THERE
WILL BE AN OPPORTUNITY FOR RADIATIONAL COOLING DUE TO A BIT OF DEW
POINT DEPRESSION, SLACK BREEZES, AND CLEAR SKIES. OVERNIGHT LOWS
WILL BE BROADLY IN THE UPPER 60S WITH DEW POINTS LIKELY GAINING A
POINT OR TWO. STABLE CONDITIONS WITH MOSTLY CLEAR SKIES WILL
REMAIN WITH DEEP LAYERED RIDGING AND CUBAN ENHANCED INHIBITION
LINGERING.

THE EAST, AND TROUGHING SLIPS EASTWARD ACROSS THE GULF.
