AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
248 PM EST MON FEB 9 2015

.DISCUSSION...
.CURRENTLY...
SCATTERED SHOWERS WITH SOME EMBEDDED THUNDERSTORMS MAINLY SOUTH
CONTINUE TO CROSS THE KEYS AREA THIS AFTERNOON. A TROUGH IS MOVING
ACROSS THE NORTHEAST GULF OF MEXICO AND BIG BEND OF NORTH FLORIDA.
WINDS ARE OUT OF THE SOUTHEAST AND GUSTY IN AND AROUND THESE
SHOWERS...AND NEAR 10 KNOTS OUTSIDE OF THESE AREAS. FROM SATELLITE WE
SEE DRY AIR MOVING AROUND A WEAKENING SHORT WAVE OVER THE EASTERN
GULF...WHILE THE BULK OF THE ENERGY IS ALREADY MOVING NORTHEAST ALONG
THE TROUGH.

.FORECAST...
AS THE TROUGH MOVES THROUGH THE AREA TONIGHT...WINDS WILL FRESHEN
QUICKLY AND SPREAD ACROSS THE ENTIRE KEYS BY MIDNIGHT. A SURFACE LOW
WILL DEVELOP EAST OF THE CAROLINAS TONIGHT. UNLIKE THE PAST FEW
SYSTEMS THIS ONE WILL MOVE FURTHER OUT TO SEA AND LIMIT THE EFFECTS
ON THE NORTH EAST MEGAPLEX. WHILE THE TROUGH MOVES FURTHER OUT TO
SEAS...A LARGE SCALE RIDGE WILL BUILD OVER THE CENTRAL PLAINS EARLY
THURSDAY...SLIDING SOUTHEASTWARD AND ARRIVING OVER THE EASTERN GULF
OF MEXICO SATURDAY MORNING. AS THE RIDGE ADVANCES ON THE GULF COAST
THE PRESSURE GRADIENT WILL STRENGTHEN RESULTING IN FRESHENING WINDS
THURSDAY EVENING THROUGH FRIDAY AFTERNOON. THEN AS THE RIDGE ARRIVES
OVER THE EASTERN GULF WINDS WILL RELAX AGAIN SATURDAY MORNING. THE
ONLY OTHER IDEA TO RELAY IS THAT THE WINDS WILL REMAIN MOSTLY OF
CONTINENTAL ORIGINS WHICH WILL STARVE THE ENVIRONMENT OF NEEDED
MOISTURE FOR ANY SIGNIFICANT RAIN CHANCES. THE COOLEST AIR OF THE
YEAR SO FAR MAY ARRIVE THIS WEEKEND WITH LOWS DIPPING INTO THE MIDDLE
50S.

&&

.MARINE...
A FRONT WILL APPROACH THE KEYS LATE THIS AFTERNOON THROUGH THE
OVERNIGHT PERIOD. WINDS WILL GRADUALLY INCREASE FROM NORTHWEST TO
EAST AND A SMALL CRAFT ADVISORY WILL SPREAD FROM THE DRY TORTUGAS
THIS EVENING...TO COVER THE ENTIRE KEYS AREA WATERS BY MIDNIGHT.
WINDS WILL QUICKLY DECREASE TUESDAY NIGHT...WHICH WILL REPEAL THE
ADVISORY BY EARLY WEDNESDAY MORNING. EXPECTING NORTH WINDS THROUGH
SATURDAY WITH A LARGE AREA OF HIGH PRESSURE BUILDING OVER THE EASTERN
UNITED STATES ON THURSDAY...INCREASING WINDS ACROSS SOUTH FLORIDA
AND THE KEYS WITH THE POTENTIAL FOR ANOTHER ADVISORY THURSDAY THROUGH
FRIDAY.

&&

.AVIATION...
VFR CEILINGS ARE EXPECTED TO PREVAIL AT THE KEY WEST AND MARATHON
AIRPORTS INTO MID AFTERNOON...WITH BRIEF MVFR OR IFR
CEILINGS/VISIBILITIES POSSIBLE AS SCATTERED SHOWERS AND A FEW
THUNDERSTORMS MOVE NORTHEAST AND EAST THROUGH THE WATERS NEAR THE
FLORIDA KEYS THROUGH EARLY EVENING. SOUTHEAST BREEZES HAVE HELD ON A
LITTLE LONGER EARLY THIS AFTERNOON AND ARE EXPECTED TO QUICKLY VEER
TO SOUTHWEST SOMETIME BETWEEN 20Z-22Z WITH GRADUAL INCREASE IN SPEEDS
AND GUSTINESS. WINDS WILL BECOME NORTHWEST LATE TONIGHT WITH FREQUENT
GUSTS NEAR OR A LITTLE OVER 20 KNOTS.

&&

.CLIMATE...
ON THIS DATE IN KEYS WEATHER HISTORY...IN 1995...THE DAILY RECORD
LOW TEMPERATURE OF 48 DEGREES WAS RECORDED FOR FEBRUARY 9 IN KEY
WEST. TEMPERATURE RECORDS FOR KEY WEST DATE BACK TO 1872.
