AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
1135 PM EST TUE FEB 12 2008

.DISCUSSION...
.CURRENTLY...
KBYX RADAR DETECTS NUMEROUS SHOWERS AND THUNDERSTORMS ON THE WATERS
FROM IN AND AROUND DRY TORTUGAS...TO THE OUTER WATERS OF MAINLAND
MONROE. ELSEWHERE...NO PRECIPITATION IS BEING DETECTED IN OUR AREA.

SURFACE ANALYSIS DEPICTS A WESTERN ATLANTIC RIDGE REACHING ACROSS
SOUTH FLORIDA...WITH AN ELONGATED AREA OF LOW PRESSURE EXTENDING
FROM THE OHIO VALLEY SOUTHWARD INTO THE EASTERN GULF OF MEXICO. THE
PRESSURE DIFFERENCE BETWEEN THESE TWO SYSTEMS IS RESULTING IN SOUTH
WINDS OF AROUND 20 KNOTS WITH GUSTS NEAR 30 KNOTS.
MEANWHILE...GOES-12 WATER VAPOR IMAGERY SHOWS A LONG WAVE TROUGH
COVERING THE GULF OF MEXICO...WITH SEVERAL VORTICITY LOBES ROTATING
WITHIN.

.SHORT TERM (OVERNIGHT)...
WITH BROAD LARGE SCALE MID AND UPPER LEVEL LIFT AND AN ABUNDANCE OF
MOISTURE IN PLACE...EXPECT SHOWERS AND THUNDERSTORMS TO REDEVELOP
OVERNIGHT ACROSS THE ISLAND CHAIN. HENCE...LIKELY POPS WITH
TEMPERATURES HOLDING IN THE LOWER TO MID 70S WILL BE MAINTAINED IN
THE PUBLIC ZONE FORECAST.

&&

.MARINE...
OUR EVENING SOUNDING REVEALS SOUTHEAST TO SOUTH WINDS OF 23 AND 27
KNOTS AT 1 AND 2 THOUSAND FEET RESPECTIVELY...WHICH COINCIDES WITH
THE KBYX VWP AND THE CUDJOE KEY WIND PROFILER. GIVEN LOWER PRESSURE
HOLDING IN THE EASTERN GULF OF MEXICO...FRESH TO STRONG WINDS SHOULD
PERSIST OVERNIGHT. HENCE...A SMALL CRAFT ADVISORY WILL REMAIN IN
EFFECT FOR ALL KEYS WATERS.
&&

.AVIATION...
INTERMITTENT MVFR CIGS AND VSBYS ARE LIKELY OVERNIGHT AT THE KEY
WEST AND MARATHON TERMINALS DUE TO SHOWERS AND THUNDERSTORMS IN THE
VICINITIES. VERY BRIEF IFR CONDITIONS WILL BE POSSIBLE IF A DIRECT
HIT OCCURS AT THE SITE BUT THIS IS NOT LIKELY. WE WILL INITIATE AN
AIRPORT WEATHER WARNING AND CONSEQUENT GROUND-STOP IF LIGHTNING
OCCURS WITHIN FIVE MILES OF THE KEY WEST TERMINAL.

&&
