DISCUSSION
ISSUED AT 512 AM EDT FRI JUL 31 2026
A MOSTLY UNEVENTFUL NIGHT FOR THE FLORIDA KEYS UNFOLDED INTO A
PEACEFUL MORNING. KBYX HAS REMAINED SHOWER-FREE FOR THE LAST
SEVERAL HOURS. LAST NIGHT'S KKEY 00Z SOUNDING REVEALED A DRIER
PROFILE EXPLAINING THE LACK OF SHOWERS EXPERIENCED OVERNIGHT.
ACROSS THE ISLAND CHAIN TEMPERATURES ARE IN THE MID TO LOWER 80S
WITH DEWPOINTS IN THE MID 70S. CLOUD COVERAGE SEEN ON NIGHTTIME
MICROPHYSICS IS MOSTLY CLEAR FOR THE LOWER KEYS WHILE THE UPPER
KEYS HAVE SOME UPPER LEVEL CLOUDS DRIFTING THROUGH. ALONG THE
REEF, MARINE LOCATIONS ARE REPORTING MOSTLY LIGHT AND VARIABLE
WINDS. FOR TODAY, WITH THESE LIGHT AND VARIABLE WINDS CLOUD LINE
DEVELOPMENT IS POSSIBLE SIMILARLY TO YESTERDAY WITH POSSIBLE
WATERSPOUTS ASSOCIATED WITH THAT. OUTSIDE OF SHOWERS PRODUCED FROM
THE CLOUD LINES, LIMITED SHOWER DEVELOPMENT IS EXPECTED FOR THE
DAY. THIS PATTERN IS EXPECTED TO LAST FOR THE NEXT FEW PERIODS. AS
A TROUGH MOVES EASTERLY ON SUNDAY, WINDS ARE EXPECTED TO FRESHEN
AND BECOME SOUTHEAST TO EAST ONCE AGAIN. THIS TROUGH WILL ALSO
REIGNITE THE MOISTURE RESULTING IN HIGHER RAIN CHANCES FOR LATER
IN THE WEEK. STAY TUNED.
MARINE
ISSUED AT 512 AM EDT FRI JUL 31 2026
NO WATCHES, WARNINGS, OR ADVISORIES ARE CURRENTLY IN EFFECT FOR
THE FLORIDA KEYS WATERS. FROM SYNOPSIS, THE WESTERN PERIPHERY OF
AN ATLANTIC SURFACE RIDGE WILL CONTINUE TO SLIDE WESTWARD ACROSS
THE FLORIDA KEYS COASTAL WATERS. THIS WILL RESULT IN A WEAK
NEBULOUS FLOW, RESULTING IN LIGHT TO GENTLE BREEZES. A COL REGION
WILL SET UP TODAY INTO THE FIRST PART OF THE WEEKEND, RESULTING IN
A POTENTIAL PERIOD OF LIGHT AND VARIABLE BREEZES. AS HIGH
PRESSURE STRENGTHENS IN THE NORTH ATLANTIC, SOUTHEAST BREEZES WILL
FRESHEN BY THE SECOND HALF OF THE WEEKEND AND INTO EARLY NEXT
WEEK.
AVIATION
(06Z TAFS)
ISSUED AT 512 AM EDT FRI JUL 31 2026
VFR CONDITIONS WILL PREVAIL AT BOTH EYW AND MTH THROUGH THE TAF
PERIOD. LIGHT AND VARIABLE WINDS TODAY COULD POTENTIALLY LEAD TO
A CLOUD LINE. NO MENTION OF VCSH AT THIS TIME BUT IF A CLOUD LINE
DOES DEVELOP IT WILL BE ADDED TO THE TERMINALS.
