DISCUSSION

A PEACEFUL NIGHT INTO A PLEASANT MORNING IS OCCURRING FOR THE
FLORIDA KEYS. KBYX RADAR HAS BEEN ECHO-FREE FOR HOURS AND
NIGHTTIME MICROPHYSICS REVEALS A CLOUD-FREE ISLAND CHAIN, THOUGH
THERE IS A NICE SWATH OF CLOUDS DRIFTING ACROSS THE EASTERN
STRAITS OF FLORIDA. TEMPERATURES ALONG THE ISLAND CHAIN ARE
CURRENTLY NEAR 50 AND DEWPOINTS NEAR 30 MAKING IT FEEL PRETTY
CHILLY OUTSIDE AND THERE ARE STILL A COUPLE MORE HOURS TO ALLOW
TO TEMPERATURES TO RADIATE A FEW DEGREES LOWER. ACROSS THE REEF,
BREEZES ARE MODERATE AS AN OVERNIGHT SURGE IS OCCURRING BUT AS THE
MORNING MOVES ALONG, BREEZES WILL SLIGHTLY SLACKEN TO GENTLE TO
MODERATE FOR THE REMAINDER OF THE DAY.
THIS MILD WEATHER IS THANKS TO A BROAD HIGH PRESSURE DOMINATING
THE SOUTHEASTERN US, WHICH WILL CONTINUE TO SUPPRESS ANY MOISTURE
ATTEMPTING TO ENTER THE AREA. UNDER THIS PATTERN THE KEYS WILL
EXPERIENCE GENTLE TO MODERATE WINDS WITH DRY CONDITIONS THROUGH
MIDWEEK AS THE HIGH REMAINS IN CONTROL. GOING INTO THURSDAY,
WINDS WILL QUICKLY FRESHEN AND BACK AS ANOTHER COLD FRONT RACES
THROUGH OUR AREA. AHEAD OF THE FRONT, RAIN CHANCES WILL SLIGHTLY
INCREASE WITH A POSSIBILITY OF A PRE-FRONTAL LINE OF SHOWERS.
CONFIDENCE IS INCREASING THAT SMALL CRAFT ADVISORY HEADLINES MAY
BE REQUIRED FROM LATE THURSDAY AND THURSDAY NIGHT. THIS FRONT WILL
THEN BRING ANOTHER ROUND OF COOLER TEMPERATURES FOR THE KEYS WITH
LOWS PROJECTED IN THE MID TO LOWER 50S FOR A MAJORITY OF THE
ISLAND CHAIN, WITH THE UPPER KEYS POTENTIALLY SEEING UPPER 40S.
STAY TUNED.
MARINE

NO WATCHES, WARNINGS, OR ADVISORIES ARE CURRENTLY IN EFFECT IN THE
FLORIDA KEYS WATERS. FROM SYNOPSIS, MODERATE, GENERALLY NORTH TO
NORTHEAST BREEZES ARE EXPECTED THROUGH WEDNESDAY. NEAR THE END OF
THE WEEK, ANOTHER COLD FRONT WILL PUSH THROUGH THE KEYS MARINE
ZONES. THIS WILL BRING ANOTHER PUSH OF FRESHENED BREEZES AND
BUILDING SEAS FOR FRIDAY INTO THE WEEKEND.
