THIS AFTERNOON AS A FEW LOW CLOUDS WERE OBSERVED MOVING OVER THE
FLORIDA KEYS. HIGH TEMPERATURES SO FAR HAVE REACHED THE UPPER 70S
AND NEAR 80 WITH DEW POINTS IN THE LOW TO MID 60S. WINDS HAVE RANGED

EARLIER THIS AFTERNOON.

.FORECAST...
A LOW PRESSURE OFF THE COAST OF DELAWARE AND ITS ASSOCIATED COLD
FRONT IS EXTENDING OVER THE CENTRAL BAHAMAS AND CUBA THIS AFTERNOON.
THIS FRONT WAS THE CAUSED OF THE SHOWERS LAST NIGHT AND THANKS TO ITS
PASSAGE...THE KEYS WILL CONTINUE TO ENJOY A PLEASANT EVENING WITH DEW
POINTS NEAR 60. ANOTHER WEAK AND DRY COLD FRONT WILL MOVE SOUTH LATER
TONIGHT AND SOME SHOWERS MIGHT BE ABLE TO AFFECT THE KEYS OVERNIGHT
AND INTO EARLY FRIDAY MORNING. BY FRIDAY AFTERNOON...A STRONG
INVERSION BASED AT 6 KFT WILL AND IS EXPECTED TO STAY THROUGH THE
WEEKEND AND INTO THE EARLY PART OF NEXT WEEK. ON SATURDAY...A HIGH
PRESSURE WILL DEVELOP OVER SOUTH CENTRAL TEXAS AND MOVE INTO THE
NORTHEAST GULF OF MEXICO. ON SUNDAY...THE HIGH WILL STRETCH EASTWARD
ACROSS THE FLORIDA PENINSULA AND BY MONDAY IT WILL CONTINUE TO MOVE
EAST INTO THE MID ATLANTIC. THIS WILL RESULT IN BENIGN CONDITIONS
FOR THE FLORIDA KEYS. TEMPERATURES WILL REMAIN NEAR NORMAL WITH
MOSTLY CLEAR SKIES AND A NICE BREEZE.

.MARINE...
GENTLE TO MODERATE NORTHWEST TO NORTH BREEZES WERE OBSERVED ACROSS
THE AVAILABLE MARINE STATIONS. A LOCALIZED AND BRIEF WIND SURGE IS

SURGE WILL ALSO INCREASE THE WINDS IN THE STRAITS OF FLORIDA
SOUTHEAST OF THE UPPER KEYS AND A SMALL CRAFT ADVISORY MAY BE
REQUIRED TONIGHT FOR THE AFOREMENTIONED WATER ZONES. ELSEWHERE...WINDS
