.DISCUSSION...
MOSTLY CLEAR SKIES AND NO PRECIPITATION ECHOES HAVE PREVAILED DURING
THE EARLY HOURS OF THIS SUNDAY NIGHT. LAND STATIONS HAVE REPORTED
NORTHWEST TO NORTH WINDS RANGING 10 TO 15 MPH...WHILE MARINE STATIONS
HAVE REPORTED 20 TO 25 KNOTS AND GUSTING. THE HIGH TEMPERATURES
PEAKED TODAY IN THE MID 60S...WITH A HIGH OF 67 DEGREES AT KEY WEST
INTERNATIONAL AIRPORT...WHICH IS 8 DEGREES BELOW NORMAL FOR THIS TIME

.FORECAST...
LOW TEMPERATURES WILL DROP TO THE MID 50S FOR KEY WEST AND THE LOWER
KEYS...AND DOWN TO NEAR 50 ACROSS THE MIDDLE AND UPPER KEYS BEFORE
SUNRISE ON MONDAY. THIS DIFFERENCE IN THE MINIMUM TEMPERATURES WILL
BE THANKS TO THE WINDS SHIFTING FROM THE NORTH...BRINGING EXTRA COOL
AIR FROM SOUTH FLORIDA INTO THE UPPER HALF OF THE KEYS. A STRONG LOW
PRESSURE SYSTEM...NOW LOCATED EAST OF THE OUTER BANKS...WILL MOVE
NORTHEAST OVER THE ATLANTIC WATERS. MEANWHILE...A HIGH PRESSURE WILL
BUILD EASTWARD OVER THE GULF OF MEXICO INTO SOUTH FLORIDA ON MONDAY.
THEN ON MONDAY NIGHT...ANOTHER COLD FRONT WILL REACH THE
KEYS...BRINGING FRESH TO STRONG BREEZES. NO MAJOR CHANGES TO THE
CURRENT FORECAST WERE NECESSARY.

&&

.MARINE...
LATEST AVAILABLE MARINE OBSERVATIONS SHOWED THAT WINDS REMAINED NEAR
20 KNOTS ACROSS THE COASTAL WATERS. THEREFORE...THE SMALL CRAFT
ADVISORY REMAINS IN EFFECT. SEAS AND WINDS WILL GRADUALLY COME DOWN
THROUGH THE NIGHT AND BASED ON GUIDANCE...THE ADVISORY COULD BE
DROP LATER TONIGHT. HOWEVER...ANOTHER COLD FRONT WILL REACH THE KEYS
MONDAY NIGHT AND A SMALL CRAFT ADVISORY WILL BE NECESSARY ONCE AGAIN.

&&

.AVIATION...
PREVAILING VFR VIS/CIGS ARE EXPECTED AT BOTH ISLAND TERMINALS OVERNIGHT
AND THROUGHOUT THE DAY ON MONDAY. FRESH NORTHWESTERLY CROSSWIND

VEERING TO THE NORTH AFTER MIDNIGHT...THEN BACKING OUT OF THE WEST
AND BECOMING A MODERATE BREEZE BY MONDAY AFTERNOON. CLOUD COVERAGE
WILL REMAIN FEW BETWEEN 030-040...BECOMING SCATTERED TOWARDS THE LATTER
HALF OF THE FORECAST PERIOD...WITH RAIN CHANCES REMAINING NEAR NIL.

&&

.CLIMATE...
ON THIS DATE IN KEY WEST WEATHER HISTORY...BACK IN THE YEAR IN
