A BEAUTIFUL DAY IS UNDERWAY ACROSS THE FLORIDA KEYS THIS MORNING.
POST FRONTAL CONDITIONS ARE IN FULL BLOOM WITH GOES 19 VISIBLE
SATELLITE IMAGERY DEPICTING MOSTLY CLEAR SKIES OVER THE ISLAND
CHAIN. THIS IS LIKELY INFLUENCED BY THE DRAINAGE OF DRY AIR VIA
NORTHERLY WINDS FROM MAINLAND FLORIDA. AS A RESULT, MODERATE
BREEZES ALONG THE REEF ARE SLIGHTLY DIFLUENT WITH NORTHWESTERLIES
OBSERVED BY THE UPPER KEYS WITH NORTHEASTERLIES OFF THE LOWER
KEYS. TEMPERATURES ARE IN THE LOWER TO MID 70S WITH COMFORTABLE
DEWPOINTS IN THE MID 60S. KBYX RADAR DETECTS A SMALL CLUSTER OF
SHOWERS JUST OFF THE COAST OF SOUTH FLORIDA REMAINING JUST OUTSIDE
OF OUR WATERS FOR NOW.
THE LOW LEVEL TROUGH OVER THE BAHAMAS YESTERDAY HAS STARTED TO
SHIFT EAST INTO THE WESTERN NORTH ATLANTIC. THIS HAS ALLOWED FOR
BREEZES TO RELAX SOMEWHAT FROM LAST NIGHT. THE DIODE OF LOW
PRESSURE TO THE EAST AND HIGH PRESSURE TO WEST WILL STILL KEEP A
MODE OF PEAKING AND LULLING BREEZES IN THE SHORT TERM WITH LESSER
EXTREMES THAN YESTERDAY. THIS MORNING'S KKEY 12Z SOUNDING NOTES
VERY DRY AIR ABOVE AN INVERSION AT 850 MB. DIFLUENT LOW LEVEL
WINDS ALONG WITH THIS DRY MASS WILL KEEP SHOWERS SUPPRESSED IN
OUR AREA FOR THE MOST PART, THOUGH A SMALL AREA OF CYCLONIC MOTION
NORTH OF ANDROS ISLAND IS CURRENTLY INDUCING SHOWERS OFF THE
SOUTHEAST FLORIDA COAST AND TREKKING SOUTH. THUS, A SLIGHT CHANCE
OF RAIN IS KEPT FOR THE REST OF TODAY. THE FORECAST IS ON TRACK
WITH NO CHANGES REQUIRED AT THIS TIME.
MARINE
ISSUED AT 1055 AM EDT THU APR 10 2025
THERE ARE CURRENTLY NO WATCHES, WARNINGS, OR ADVISORIES IN EFFECT
FOR THE COASTAL WATERS OF THE FLORIDA KEYS. FROM SYNOPSIS, HIGH
PRESSURE OVER THE GULF AND LOW PRESSURE TO NORTH OF THE BAHAMAS
WILL RESULT IN PEAKING AND LULLING BREEZES CONTINUING THROUGH
EARLY FRIDAY. ANOTHER FRONTAL PASSAGE MAY PRESS THROUGH THE KEYS
LATE WEEK OR EARLY IN THE WEEKEND WITH ANOTHER ROUND OF FRESHENING
NORTHWEST TO NORTH BREEZES. HIGH PRESSURE WILL RETURN TOWARDS THE
START OF NEXT WEEK, CLOCKING WINDS AROUND TO THE EAST WHILE
SLACKENING.
AVIATION
(15Z TAFS)
ISSUED AT 1055 AM EDT THU APR 10 2025
VFR CONDITIONS WILL PREVAIL AT BOTH EYW AND MTH THROUGH THE TAF
PERIOD. DRY AIR SHOULD KEEP SHOWER ACTIVITY LIMITED. WINDS WILL BE
NORTHERLY AT 10 TO 15 KNOTS THROUGH THIS AFTERNOON, MAKING POTENTIAL
CROSSWIND CONCERNS AT BOTH TERMINALS.
