AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
1033 PM EST TUE MAR 5 2013

.DISCUSSION...
A WEAK RIDGE HAS SETTLED OVER THE FLORIDA KEYS AND ADJACENT WATER
THIS EVENING...WITH RESULTING LIGHT AND VARIABLE BREEZES AT MOST
LOCATIONS. THE AIR MASS REMAINS TOO DRY AND STABLE FOR ANY
PRECIPITATION OR DEEP CLOUDS...WITH RELATIVELY COOL AND DRY AIR EVEN
PERSISTING AT THE SURFACE. CURRENTLY...AIR TEMPERATURES RANGE BETWEEN
A LOW OF 59F AT INTERIOR RAMROD KEY TO 69F ALONG WATERFRONT
EXPOSURES. IT IS 62F HERE AT THE FORECAST OFFICE IN MID-TOWN KEY
WEST. HOWEVER...THE AIRPORT IS 66F AND THE NOS WATER LEVEL STATION AT
THE TRUMAN WATERFRONT IS 68F.

FORECASTS LOOK FINE FOR THE OVERNIGHT. SKIES SHOULD REMAIN MOSTLY
CLEAR WITH A WIDE RANGE OF LOW TEMPERATURES IN THE UPPER 50S AND
LOWER 60S. LIGHT WINDS SHOULD TURN OUT OF THE SOUTHWEST AND BEGIN TO
FRESHEN JUST BEFORE DAYBREAK.

A COLD FRONT AND WIND SHIFT ARE STILL EXPECTED TO SWEEP THROUGH THE
FLORIDA KEYS WEDNESDAY AFTERNOON...MOST LIKELY BETWEEN 100 PM AND
400 PM EST. HOWEVER...SOUTHWEST TO WEST WINDS WILL REALLY CRANK UP
BEFORE THE FRONT GETS HERE...ESPECIALLY IN UPPER KEYS COMMUNITIES.
&&

.MARINE...
SMALL CRAFT ADVISORIES LIKELY WILL GO INTO EFFECT FOR ALL ZONES
WEDNESDAY AFTERNOON OR EVENING...WITH ADVISORIES UP FIRST FOR THE
ZONES COVERING THE EXTREME SOUTHEASTERN GULF OF MEXICO AND FLORIDA
BAY. A WEAK RIDGE TRANSITING THE KEYS OVERNIGHT WILL KEEP BREEZES
LIGHT AND VARIABLE UNTIL JUST BEFORE DAYBREAK WHEN A LIGHT SOUTHWEST
BREEZE SHOULD ENSUE. SOUTHWEST TO WEST BREEZES WILL FRESHEN
SUBSTANTIALLY DURING THE MORNING BEFORE SHIFTING OUT OF THE NORTHWEST
AND SURGING OVER 20 KNOTS AS THE COLD FRONT MOVES THROUGH. LATEST
AVAILABLE INFORMATION SUGGESTS A FRONTAL PASSAGE AND WIND SHIFT
BETWEEN 130 PM AND 400 PM EST.
&&

.AVIATION...
THROUGH 07/00Z...VFR CONDITIONS WILL PREVAIL OVERNIGHT AND INTO
WEDNESDAY. WINDS WILL GRADUALLY SHIFT TO THE WEST THROUGH THE PERIOD
UNTIL A RAPID SHIFT TO THE NORTH...SOMETIME AFTER 06/18Z TOMORROW.
THE DISSIPATING FRONT THAT WILL BE RESPONSIBLE FOR THIS WIND SHIFT
ONLY HAS A SLIGHT CHANCE OF GENERATING A BRIEF LINE OF SHOWERS ALONG
ITS LEADING EDGE.
