AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
1028 PM EDT SAT MAR 28 2015

.DISCUSSION...
CURRENTLY - A ~1030 MB HIGH CELL IS DESCENDING INTO THE SOUTHEASTERN
UNITED STATES...IN WAKE OF LAST NIGHTS COLD FRONT THAT SWEPT THROUGH
THE KEYS. COOLER AND DRIER AIR CONTINUE TO FILTER DOWN INTO THE
KEYS ON FRESHENING NORTHERLIES. AREAS IN THE DIRECT LEE OF SOUTH
FLORIDA ARE LAGGING BEHIND WIND WISE. TEMPERATURES ARE NEAR 70
DEGREES...WITH DEW POINTS IN THE LOWER 50S. THE ENVIRONMENT IS QUITE
STABLE...HOWEVER THICK MID AND UPPER LEVEL CLOUDS CONTINUE TO STREAM
ACROSS THE AREA...CARRIED BY THE SUBTROPICAL JET.

SHORT TERM UPDATE (OVERNIGHT) - WINDS SHOULD COME UP MORE UNIFORMLY
OVERNIGHT...ESPECIALLY AS COOL AIR DRAINAGE DEVELOPS OFF OF SOUTH
FLORIDA. WHILE THE SHALLOW NEARSHORE WATERS HAVE COOLED ABOUT 10
DEGREES FROM YESTERDAY...THEY ARE STILL IN THE MID 70S. THIS SHOULD
PROVIDE SOME RESISTANCE TO FALLING TEMPERATURES. EXPECT OVERNIGHT
LOWS OF 60 TO 65...WITH THE COOLEST TEMPERATURES IN THE PORTIONS OF
THE UPPER KEYS. NO PRECIPITATION IS EXPECTED...BUT SKIES WILL REMAIN
CLOUDY.

&&

.MARINE...
HIGH PRESSURE MOVING INTO THE SOUTHEASTERN UNITED STATES...ALONG WITH
SOUTH FLORIDA COOLING OFF WILL ALLOW FOR NORTHERLY WINDS TO INCREASE
MORE UNIFORMLY TO NEAR 20 KNOTS OVERNIGHT. A SMALL CRAFT ADVISORY
REMAINS IN EFFECT FOR ALL KEYS WATERS. NO PRECIPITATION IS EXPECTED.
ONLY MINOR ADJUSTMENTS MADE TO FIRST PERIOD WIND TRANSITION WORDING IN
THE EVENING MARINE UPDATE.

.AVIATION...
VFR CONDITIONS WILL BE OBSERVED TONIGHT AND TOMORROW
ACROSS THE KEY WEST AND MARATHON TERMINALS. FEW LOW CLOUDS WILL BE
BRIEF AND CEILINGS WILL BE NEAR 20000 FT WHICH WILL BECOME SCATTERED
ON SUNDAY MORNING. NORTHERLY CROSSWINDS OF 10 TO 20 KNOTS...STRONGER
WITH HEIGHT...WILL CONTINUE OVERNIGHT...TURNING TO THE NORTHEAST ON
SUNDAY AFTERNOON.
