AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
908 PM EST TUE JAN 27 2015

.DISCUSSION...
.CURRENTLY...
THE ROBUST UPPER LEVEL LOW NEAR THE NEW ENGLAND COAST CONTINUES TO
;LIFT OUT TO THE NORTH...CURRENTLY MOVING ACROSS THE COAST OF MAINE
INTO THE CANADIAN MARITIMES. A LARGE AREA OF HIGH PRESSURE IS SLIDING
EASTWARD ACROSS THE GULF OF MEXICO. DRY AIR HAS ENGULFED THE KEYS
AREA. WINDS ARE HIGHER ON THE UPPER KEYS THAN THE LOWER LIKELY DUE TO
THE COLD AIR DRAINING OFF THE MAINLAND.

.FORECAST...
AS THE STRONG LOW MOVES OUT OVER CANADA...THE TRAILING RIDGE WILL
MOVE OVER THE GULF WILL BE ABSORBED BY A LARGER AREA OF HIGH PRESSURE
MOVING INTO THE OHIO RIVER VALLEY. THIS WILL TIGHTEN THE PRESSURE
GRADIENT AND TURN WINDS MORE NORTH OVERNIGHT INTO WEDNESDAY NIGHT. A
TROUGH WILL SPREAD EASTWARD ACROSS THE FRONT RANGE WEDNESDAY NIGHT
FRAGMENTING THE RIDGE IN THE EAST. WHILE THE TROUGH TREKS EASTWARD
THE SOUTHERN FRAGMENT OF THE RIDGE WILL MOVE SOUTHWARD OVER THE
FLORIDA PENINSULA. WEDNESDAY NIGHT THROUGH THURSDAY WINDS WILL TURN
NORTHEAST AND DECREASE LATE THURSDAY NIGHT AND FRIDAY. THERE WILL BE
LITTLE TO NO CHANCE OF PRECIPITATION THROUGH THE NEAR TERM FORECAST.

&&

.MARINE...
WINDS ARE SURGING FROM EAST TO WEST THIS EVENING AND WILL TURN TO THE
NORTH OVERNIGHT. EXPECT 15 TO 20 KNOTS EVERYWHERE AFTER MIDNIGHT WITH
THE POTENTIAL FOR NEAR 20 KNOTS OVER FLORIDA BAY AND HAWK CHANNEL
SOUTH OF THE UPPER KEYS DUE TO COLD AIR DRAINAGE OFF THE SOUTHERN TIP
OF FLORIDA. WILL WAIT FOR MORE C-MAN OBSERVATIONS FROM LONG KEY AND
MOLASSES REEF BEFORE UPDATING THE CURRENT FORECAST. WINDS WILL TURN
MORE NORTHEAST THEN EAST WEDNESDAY NIGHT THROUGH THURSDAY NIGHT...AND
DECREASE LATE THURSDAY NIGHT THROUGH FRIDAY. SMALL CRAFT SHOULD
EXERCISE CAUTION ON ALL KEYS WATERS TONIGHT. FLORIDA BAY AND HAWK
CHANNEL SOUTH OF THE UPPER KEYS MAY REQUIRE AN ADVISORY AS MENTIONED
ABOVE.
