DISCUSSION
ISSUED AT 410 AM EST SUN FEB 8 2026
ANOTHER QUIET NIGHT FOR THE FLORIDA KEYS WITH NO RAIN YET AGAIN
DETECTED ON THE KBYX RADAR. HIGH PRESSURE DIVING OUT OF CANADA AND
EXPANDING EQUATORWARD HAS ALLOWED OUR WINDS TO CLOCK AROUND FROM
THE NORTHEAST THIS MORNING. AS A RESULT, WE ARE GETTING A LATE
NOCTURNAL SURGE OFF THE MAINLAND WITH MOST MARINE PLATFORMS
READING MODERATE TO FRESH BREEZES. THE RELATIVELY STRONGER WINDS
THROUGH THE OVERNIGHT HAS ALSO MEANT THAT TEMPERATURES HAVE STAYED
IN THE UPPER 50S TO NEAR 60.
THIS MOST RECENT NOCTURNAL SURGE WILL END QUICKLY AFTER SUNRISE
AND BREEZES SHOULD SLACKEN TO LIGHT TO GENTLE ACROSS OUR WATERS
NORTH OF THE ISLAND CHAIN, WHILE SLACKENING ONLY TO GENTLE TO
MODERATE FOR THE HAWK CHANNEL AND STRAITS OF FLORIDA WATERS. DRY
AIR WILL CONTINUE TO FILTER IN AS THE AFOREMENTIONED BROAD SURFACE
HIGH SETTLES ALONG THE EASTERN SEABOARD TODAY AND TONIGHT. AS IT
SETTLES ALONG THE EASTERN SEABOARD IT WILL BRIEFLY BECOME
DISORGANIZED AS A POTENT SHORTWAVE ALOFT MOVES THROUGH MISSISSIPPI
AND TENNESSEE VALLEYS ON MONDAY. BY TUESDAY THE SURFACE HIGH WILL
RECONSOLIDATE JUST OFF THE SOUTHEASTERN U.S. COAST AND THEN SLOWLY
MEANDER EASTWARD ACROSS THE ATLANTIC.
AT THIS TIME, WHILE THE SHORTWAVE WILL DIVE INTO THE SUNSHINE
STATE LATE MONDAY INTO EARLY TUESDAY, WE'RE NOT EXPECTING THIS
FEATURE TO IMPACT THE KEYS. THIS IS BECAUSE A LOW LEVEL MEAN
LAYERED RIDGE WILL SLIDE EAST ACROSS THE GULF BASIN AND HELP TO
STEER ANY LOW LEVEL ENERGY WELL TO OUR NORTH AND NORTHEAST.
LOCALLY, WE WILL SEE WINDS WAX AND WANE THROUGH THE NEXT SEVERAL
DAYS, TENDING TO PEAK DURING THE OVERNIGHT HOURS. TEMPERATURES
THROUGH THIS PERIOD LOOK TO BE REMAIN FAIRLY SIMILAR WITH DAYTIME
HIGHS REACHING INTO THE LOWER TO MID 70S AND OVERNIGHT LOWS
FALLING INTO THE 60S.
MARINE
ISSUED AT 410 AM EST SUN FEB 8 2026
A LATE, WEAK NOCTURNAL SURGE IS ONGOING ACROSS THE FLORIDA KEYS
THIS MORNING WITH MODERATE TO FRESH NORTHEAST BREEZES. THESE
BREEZES WILL SLACKEN SHORTLY AFTER SUNRISE, MORE NOTICEABLY ACROSS
THE NEARSHORE WATERS NORTH OF THE ISLAND CHAIN. AS HIGH PRESSURE
SETTLES ACROSS THE EASTERN SEABOARD AND SLOWLY RE-CONSOLIDATES OFF
THE SOUTHEAST U.S. COAST, BREEZES WILL UNDERGO A WAX AND WANE
CYCLE. BREEZES WILL TEND TO PEAK DURING THE OVERNIGHT AND SLACKEN
DURING THE LATE MORNING AND EARLY AFTERNOON HOURS. AS THE HIGH
DEVELOPS OFF THE SOUTHEAST U.S. COAST, WINDS WILL HAVE MORE OF AN
EASTERLY TENDENCY.
AVIATION
(06Z TAFS)
ISSUED AT 410 AM EST SUN FEB 8 2026
VFR CONDITIONS ARE EXPECTED TO PREVAIL THROUGH THE TAF PERIOD AT
BOTH TERMINALS. NEAR SURFACE WINDS WILL REMAIN MAINLY NORTH EARLY
THIS MORNING, BECOMING NORTH TO NORTHEAST AFTER DAYBREAK, AND
BECOMING NORTHEAST TO EAST THIS EVENING AND OVERNIGHT. FREQUENT
GUSTS OF 20 TO 23 KNOTS ARE EXPECTED THIS MORNING CREATING FOR A
CROSSWIND. THE GUSTS ARE EXPECTED TO RELAX HEADING INTO THE
AFTERNOON HOURS. DRY AIR WILL ALSO CONTINUE TO DOMINATE WITH NIL
RAIN CHANCES PREVAILING.
CLIMATE
