WEATHER HAS REMAINED TOASTY, YET UNREMARKABLE, THIS EVENING ALONG
THE FLORIDA KEYS, WHICH IS A BIT OF A DIFFERENCE COMPARED TO 24
HOURS AGO! LIKE CLOCKWORK, THE AFTERNOON CONVECTION OVER THE
PENINSULA HAS SLOWLY BEEN DISSIPATING OVER THE PAST FEW HOURS.
FORTUNATELY FOR US, NONE OF THIS CONVECTION HAS MADE IT TO OUR
AREA. RESIDUAL OUTFLOW BOUNDARIES ALSO DID NOT MAKE IT TO OUR
AREA, AND THIS IS ALSO GOOD NEWS BECAUSE THESE CAN BE A GOOD
SOURCE FOR LIFT TO GET OUR OWN CONVECTION GOING. ALL IN ALL,
WEATHER HAS REMAINED QUIET AT HOME TONIGHT, AND WE WERE ABLE TO
WATCH THE THUNDERSTORMS UNFOLD OVER THE PENINSULA WITHOUT HAVING
TO WORRY ABOUT ANYTHING HERE.
EVEN THOUGH WEATHER THIS EVENING WAS QUIET, IT WAS ALSO QUITE
TOASTY. WHEN CLIMATE STATISTICS WERE COMPILED THIS EVENING, THE
KEY WEST INTERNATIONAL AIRPORT HAD TIED THE DAILY RECORD HIGH
TEMPERATURE OF 92F. THIS RECORD WAS PREVIOUS RECORDED IN 1873.
DEWPOINT TEMPERATURES DURING THE LATE AFTERNOON AND EARLY EVENING
HOURS WERE IN THE LOWER TO MID 70S, SO THE MAJORITY OF OUR ISLAND
COMMUNITIES WERE EXPERIENCING HEAT INDICES ANYWHERE FROM THE MID
90S TO NEAR 100F. HAPPY SUMMERTIME TO US.
THE INHERITED FORECAST PACKAGE ADVERTISES PARTLY CLOUDY SKIES WITH
10 PERCENT POPS FOR THE OVERNIGHT, AND THERE IS NO INDICATION THAT
THIS NEEDS ANY ADJUSTMENT OR UPDATE. WE CAN COUNT ON ONE HAND HOW
MANY CLOUDS ARE CURRENTLY ACROSS OUR SKIES AS DEPICTED ON THE
GOES-19 NIGHTTIME MICROPHYSICS SCAN, BUT WE CAN'T RULE OUT MORE
FAIR WEATHER CLOUDS BUILDING IN DUE TO THE TROPICAL NATURE OF OUR
ENVIRONMENT. THERE ARE ALSO LIKELY A FEW GHOST BOUNDARIES FROM THE
EARLIER CONVECTION OVER THE MAINLAND, SO A STRAY SHOWER OR
THUNDERSTORM DURING THE OVERNIGHT CANNOT BE RULED OUT.
MARINE
ISSUED AT 948 PM EDT FRI MAY 23 2025
THERE ARE NO WATCHES, WARNINGS, OR ADVISORIES IN EFFECT ACROSS THE
FLORIDA KEYS WATERS. FROM SYNOPSIS, LIGHT TO GENTLE BREEZES
ACROSS THE FLORIDA KEYS WILL PREVAIL THROUGH SATURDAY. SHOWER AND
THUNDERSTORM CHANCES INCREASE OVER THE WEEKEND INTO NEXT WEEK AS A
LOW PRESSURE SYSTEM OVER THE EASTERN CONUS MOVES INTO THE
ATLANTIC AND BREEZES SHIFT SOUTHEASTERLY. BREEZES MAY FRESHEN TO
MODERATE TO FRESH OVER THE STRAITS OF FLORIDA EARLY NEXT WEEK.
AVIATION
