THE GRADUAL DOWNWARD AND SOUTHERLY TREND IN SURFACE WINDS ACROSS
THE FLORIDA KEYS CONTINUES TODAY. THE OVERNIGHT WIND SURGE OCCURRED
AS EXPECTED WITH GUSTS OF 24 KNOTS OBSERVED AT SAND KEY.
CURRENTLY, BREEZES ALONG THE REEF ARE SLACKENING TO MODERATE
BREEZES. EAST SOUTHEASTERLY WINDS ARE PREVAILING ACROSS THE CWA.
TEMPERATURES ARE ON TRACK TO REACH THE LOW TO MID 80S, AND DEW
POINTS ARE OSCILLATING BETWEEN THE MID AND UPPER 60S. GOES-19 DAY
CLOUD PHASE RGBS SHOW CLUSTERS OF SHALLOW CLOUD COVER ACROSS THE
ISLAND CHAIN, AND THE KBYX RADAR OBSERVATIONS SHOW PRECIPITATING
SHOWERS OVER THE OUTER GULF WATERS AROUND THE DRY TORTUGAS.
OTHERWISE, EXPECT ANOTHER MOSTLY UNEVENTFUL DAY ACROSS THE KEYS.
THE MORNING 12Z SOUNDING DETECTED AN INCREASE IN OVERALL MOISTURE
ACROSS THE KEYS. PWAT VALUES INCREASED TO NEAR THE 25TH PERCENTILE
THIS MORNING INSTEAD OF THE 10TH PERCENTILE SEEN YESTERDAY. THE
SURFACE TO 850 MB LAYER WAS OCCASIONALLY SATURATED, CORROBORATING
THE ADDITIONAL CLOUD COVER SEEN BY GOES-19. ABOVE THE BOUNDARY
LAYER, A COLLAPSE IN WIND SPEED SUGGESTS SUBSIDENCE IS STILL
ONGOING. LIGHTNING IS NOT A THREAT FOR THIS PERIOD AS THE
ENVIRONMENT WILL STAY DRY ABOVE 6000 TO 7000 FT. THUS FEW, IF ANY,
CHANGES ARE EXPECTED TO THE MORNING UPDATE, AND TONIGHT LOOKS TO
BE ANOTHER QUIET MAY EVENING.
