AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
404 AM EST SAT MAR 12 2016

.DISCUSSION...
.CURRENTLY...
A LOOK AT SATELLITE DATA WE FIND A TROUGH LINGERING OVER THE TEXAS
COAST. THIS TROUGH IS ERODING THE WESTERN EDGE OF AN AREA OF HIGH
PRESSURE NORTH OF THE BAHAMAS. SOUTHEAST WINDS HAVE DECREASED DURING
THE LAST SEVERAL HOURS WITH THE ISLAND TERMINALS REPORTING AROUND 10
KNOTS...AND ALL THE C-MAN STATIONS REPORTING 15 KNOTS...WITH HIGHER
GUSTS EXCEPT FOR THE LAST HOUR AT SAND KEY SHOWING NEAR 20 KNOTS.

.SHORT TERM (TODAY THROUGH SUNDAY NIGHT)...
THE TROUGH NEAR EAST TEXAS WILL CONTINUE TO SLIDE TO THE
EAST...IMPACTING THE WESTERN EDGE OT THE RIDGE MENTIONED ABOVE. AS
THESE INTERACT...THE PRESSURE GRADIENT WILL WEAKEN...RESULTING IN
DECREASING WINDS THROUGH THE DAY. DUE TO THE TROUGH MOVING ACROSS
THE GULF OF MEXICO WILL KEEP A SLIGHT CHANCE OF SHOWERS IN THE SHORT
TERM FORECAST AS THERE WILL BE SOME WEAK LIFTING AND HIGHER MOISTURE
CROSSING THE AREA THROUGH SUNDAY NIGHT.

&&

.LONG TERM (MONDAY THROUGH FRIDAY)...
THE INITIAL TROUGH WILL LIFT OUT WHILE A COLORADO CLIPPER MOVES
ACROSS THE FRONT RANGE ON SUNDAY...WITH THE TROUGH MOVING OFF THE
FLORIDA / GEORGIA COAST MONDAY. A ZONAL FLOW WILL PRECLUDE ANY
FRONTAL PASSAGE FOR THE KEYS AREA...AND THE LESS FAVORABLE RIGHT EXIT
REGION OF THE JET WILL HELP A MID LEVEL RIDGE SUBDUE CHANCES FOR
SHOWERS MONDAY NIGHT THROUGH TUESDAY NIGHT. WILL KEEP SLIGHT CHANCE
OF SHOWERS IN WEDNESDAY THROUGH FRIDAY ALTHOUGH GUIDANCE IS NOT VERY
BULLISH ON THIS PROSPECT.

&&

.MARINE...
WILL KEEP A CAUTIONARY STATEMENT IN FOR THE FLORIDA STRAITS AS
BREEZES CONTINUE TO DECREASE TODAY. EXPECTING TO REMOVE ALL HEADLINES
LATE THIS AFTERNOON OR THIS EVENING. A TROUGH IS MOVING SLOWLY
EASTWARD ACROSS THE WESTERN GULF OF MEXICO...ERODING THE WESTERN EDGE
OF AN AREA OF HIGH PRESSURE LOCATED EAST OF THE FLORIDA / GEORGIA
COAST. THE RESULT OF THIS ERODING HIGH PRESSURE WILL BE A GRADUAL
DECREASE IN BREEZES THROUGH SATURDAY NIGHT...AND LASTING INTO
THURSDAY.

&&

24 HOURS. SUSTAINED EAST TO SOUTHEAST WINDS NEAR 20 KNOTS EXPECTED
