AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
939 AM EST WED NOV 18 2015

.DISCUSSION...
.CURRENTLY...
THE SATELLITE VIEW OF THE UNITED STATES SHOWS THE LARGE UPPER LOW
SPINNING ACROSS THE OZARKS AND CENTRAL MISSISSIPPI VALLEY THIS
MORNING. THE SURFACE FRONT ASSOCIATED WITH THIS UPPER LOW AND TROUGH
IS PASSING OVER EASTERN LOUISIANA AT THIS HOUR. CLOSER TO HOME WE
HAVE A LINE OF SHOWERS JUST TO THE WEST OF THE LOWER KEYS ON THE
SOUTHERN FRINGE OF AN AREA OF HIGH PRESSURE NOW CENTERED OVER THE
NEW ENGLAND COAST WITH THE AXIS EXTENDING ACROSS SOUTH FLORIDA AND
THE KEYS. WINDS ARE OUT OF THE SOUTHEAST NEAR 20 KNOTS SOUTH OF THE
ISLAND CHAIN...NEAR 15 KNOTS AND GUSTY AT SMITH SHOAL...10 TO 15
KNOTS AT LONG KEY...AND NEAR 15 KNOTS AND GUSTY AT PULASKI SHOAL. THE
ISLAND TERMINALS ARE BLOWING 10 TO 15 KNOTS WITH HIGHER GUSTS. WINDS
ARE HIGHEST IN THE INFLOW CHANNEL TO THE FRONT...WHICH IS CO-LOCATED
WITH THE LINE OF SHOWERS NEAR THE LOWER KEYS.

.FORECAST...
LITTLE CHANGE TO THE CURRENT FORECAST IS EXPECTED FOR THIS UPDATE.
WILL RAISE RAIN CHANCES FOR THE LOWER KEYS WHILE KEEPING THE CHANCE
WORDING...WILL SPLIT OUT THE LOWER KEYS WITH 50 PERCENT AND LEAVE THE
MIDDLE AND UPPER KEYS AT 30 PERCENT. THE FRONT MENTIONED ABOVE WILL
CONTINUE TO TREK ACROSS THE NORTHERN GULF OF MEXICO WHILE THE PARENT
LOW SLIDES TO THE NORTHEAST ACROSS THE GREAT LAKES. THE FRONT ACROSS
THE GULF COAST WILL STRETCH OUT WEST TO EAST...WHILE THE WARM WATERS
OF THE GULF OF MEXICO MODIFY THE AIR MASS. THIS WILL ALSO STALL THE
FRONT OVER THE EASTERN GULF WEDNESDAY NIGHT AND THURSDAY. WITH THE
TROUGH LIFTING OUT TO THE NORTHEAST...THE NEXT AREA OF HIGH PRESSURE
WILL BUILD INTO THE DEEP SOUTH AND NORTHERN GULF COAST THURSDAY
NIGHT. THIS RIDGE WILL FORCED TO SPREAD NORTHEASTWARD THROUGH
SATURDAY NIGHT...AHEAD OF THE NEXT IN A SERIES OF TROUGH / RIDGE
COMPLEXES TREKKING ACROSS THE CENTRAL PLAINS AND MISSISSIPPI VALLEY.
THE CURRENT RUN OF THE MODEL GUIDANCE BRINGS THE TROUGH AXIS FURTHER
SOUTH AND IS PROGGED TO PASS THROUGH THE KEYS AREA EARLY NEXT WEEK.
IN THE WAKE OF THIS FRONTAL PASSAGE...AN ROBUST AREA OF HIGH PRESSURE
WILL BUILD OVER THE SOUTHEASTERN STATES MONDAY AFTERNOON.

&&

.MARINE...
A SMALL CRAFT ADVISORY REMAINS IN EFFECT FOR THE FLORIDA STRAITS AND
HAWK CHANNEL THIS MORNING DUE TO SOUTHEAST WINDS NEAR 20 KNOTS AND
HIGHER GUSTS. SMALL CRAFT SHOULD EXERCISE CAUTION ON KEYS WATERS
NORTH OF THE ISLAND CHAIN INCLUDING FLORIDA BAY...THE BAY AND GULF
SIDE WATERS...AND THE SOUTHEASTERN GULF OF MEXICO UNTIL WINDS
DECREASE LATER THIS EVENING. A LARGE AREA OF HIGH PRESSURE CENTERED
OVER THE NEW ENGLAND COAST WITH THE RIDGE AXIS EXTENDING THROUGH THE
KEYS AREA IS RESPONSIBLE FOR THESE WINDS. A TROUGH MOVING THROUGH
THE MISSISSIPPI VALLEY WILL PUSH THE RIDGE OUT TO THE NORTHEAST
TODAY...AND THE STRONG PRESSURE GRADIENT WITH IT. WINDS WILL INCREASE
AGAIN THURSDAY NIGHT AND FRIDAY AS A NEW RIDGE BUILDS ACROSS THE DEEP
SOUTH IN THE WAKE OF THE TROUGH.

&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL AT EYW AND MTH TODAY AND TONIGHT.
SUSTAINED EAST TO SOUTHEAST WINDS OF 20 TO 25 KNOTS FROM JUST OFF THE
SURFACE TO ABOUT 3000 FEET WILL DECREASE TO 15 TO 20 KNOTS TONIGHT.

&&

.CLIMATE...
ON THIS DATE IN FLORIDA KEYS WEATHER HISTORY...IN 1886...THE HIGH
TEMPERATURE IN KEY WEST WAS 90 DEGREES. THIS SET THE DAILY RECORD FOR
MAXIMUM TEMPERATURE MEASURED IN KEY WEST ON NOVEMBER 18TH...A RECORD
WHICH STILL STANDS 129 YEARS LATER. TEMPERATURE RECORDS AT KEY WEST
DATE BACK TO 1872.

&&

.KEY WATCHES/WARNINGS/ADVISORIES...
FL...NONE.
GM...SMALL CRAFT ADVISORY UNTIL 5 PM EST THIS AFTERNOON FOR
