AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS NATIONAL WEATHER SERVICE KEY WEST FL 1000 AM EDT TUE JUN 2 2009 .DISCUSSION...IN THE UPPER LEVELS...700-200 MB...LATEST AVAILABLE SATELLITE IMAGERY OVERLAID WITH STREAMLINE ANALYSIS AS OF 900 AM DETECT A 40 TO 50 KNOT SOUTHERN BRANCH OF THE JETSTREAM MOVING FROM CENTRAL MEXICO TO ACROSS THE SOUTHERN GULF OF MEXICO AND OVER THE FLORIDA KEYS. A WARM CORE MID AND UPPER ANTICYCLONE REMAINS FIXED OVER THE WESTERN CARIBBEAN SEA. THE FLORIDA KEYS ARE BENEATH THE NORTHERN PERIPHERY OF THIS HIGH PRESSURE SYSTEM...BENEATH WEAK ANTICYCLONIC FLOW ALOFT. IN THE LOWER TO MIDDLE LEVELS...SURFACE TO 700 MB...LATEST SATELLITE IMAGERY OVERLAID WITH SURFACE OBSERVATIONS AND ANALYSIS AS OF 900 AM DETAILS ONLY A WEAK RIDGE OVER THE SOUTHEASTERN UNITED STATES. ON THE REGIONAL SCALE...A NEAR 1020 MB RIDGE WAS POSITIONED ACROSS THE SOUTH FLORIDA PENINSULA. THE 12Z KEY WEST MORNING SOUNDING STILL ILLUSTRATED AN OVERALL MODERATELY MOIST TO MOIST SOUNDING WITH PWAT AT 1.75 INCHES OR .03 INCHES HIGHER THAN 24 HOURS AGO. HOWEVER...THERE WAS AMPLE DRY AIR IN THE 900-800 MB LAYERS AS WELL AS IN THE 700 TO 500 MB LAYERS. THERE WAS A LIGHT SOUTHEAST FLOW PRESENT FROM THE SURFACE TO 5000 FOOT LAYERS. .CURRENTLY...AS OF 900 AM...LATEST VISIBLE SATELLITE IMAGERY SHOWERS PARTLY TO MOSTLY CLOUDY SKIES ENCOMPASSING MUCH OF THE KEYS ISLAND CHAIN. KEY WEST RADAR SCANS DISPLAY ONLY ISOLATED SHOWERS SOUTH OF THE ISLAND CHAIN...BUT SCATTERED SHOWERS AND THUNDERSTORMS ARE PRESENT WITHIN NORTHWARD MOVING BOUNDARIES IN THE NEARSHORE AND OFFSHORE GULF WATERS. TEMPERATURES OUTSIDE OF SHOWERS OVER THE ISLANDS HAVE REACHED THE MIDDLE 80S WITH DEWPOINTS IN THE MIDDLE 70S. C-MAN STATIONS ARE REGISTERING LIGHT TO GENTLE EAST TO SOUTHEAST WINDS BETWEEN 5 AND 10 KNOTS ALONG THE REEF AND IN SOUTHERN FLORIDA BAY. .SHORT TERM...REST OF TODAY...IN THE MIDDLE AND UPPER LEVELS(500-200 MB)...THE LATEST AVAIL RUNS OF THE LARGE SCALE MODELS CONTINUE TO SHOW THE NORTHERN PERIPHERY OF THE WARM CORE CARIBBEAN ANTICYCLONE TO REMAIN IN PLACE THROUGH THE REST OF THE DAY. ACCORDING TO THE 06Z GFS FORECAST SOUNDING...THIS WOULD ALLOW FOR SOME SLIGHT MID TO UPPER LEVEL WARMING AND DRYING...WITH THE 500 MB TEMP WARMING A DEGREE OR TWO THROUGHOUT THE DAY. THE 06Z NAM AND 06Z GFS SOUNDINGS ARE FORECASTING PWAT TO REMAIN BETWEEN 1.75 AND 2.00 INCHES THROUGH 00Z. GIVEN ONLY SLIGHT MIXING AND WARMING...WHATEVER MID AND UPPER DRY AIR THATS IN PLACE WILL HAVE LITTLE AFFECT TO QUELL A PATTERN CONDUCIVE TO STRONG MESOSCALE FORCING. THE STRONG MESOSCALE IMPACTS ARE DUE TO THE AMOUNT OF AVAILABLE LOW TO MIDDLE LEVEL MOISTURE COUPLED WITH NORMAL JUNE INSOLATION. IN THE LOWER AND MIDDLE LEVELS...(SURFACE TO 700 MB)...THIS AFTERNOON...A WEAK LOWER LEVEL RIDGE HAS BECOME BETTER ESTABLISHED ACROSS THE SOUTH FLORIDA PENINSULA...HOWEVER...GIVEN ABUNDANT BOUNDARIES IN PLACE ACROSS THE NEARSHORE AND OFFSHORE GULF WATERS...WOULD EXPECT SCATTERED SHOWERS AND THUNDERSTORMS TO CONTINUE TO FIRE THROUGH THE REST OF THE MORNING AND THE AFTERNOON ACROSS THESE WATERS. AS THE DAY ROLLS ON AND ADDITIONAL HEATING OCCURS OVER THE ISLANDS AND THE SOUTH FLORIDA MAINLAND...LOWER LEVEL WINDS WILL BACK TO A FAVORABLE DIRECTION FOR CUMULUS LINE CONVECTION. THIS WILL HELP TO FIRE UP SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS NEAR THE KEYS. ANY OF THESE BOUNDARIES IN THE LOWER KEYS WILL BE TOO CLOSE TO THE BOUNDARIES THAT ARE PRESENTLY ACTIVE IN THE IMMEDIATE NEARSHORE GULF WATERS...THUS INITIATING NEW CONVECTION NEAR AND OVER THE LOWER KEYS. AS A RESULT...MAY RAISE UP POPS ACROSS THE LOWER KEYS INTO THE HIGHER OR HIGH CHANCE CATEGORY FOR THE AFTERNOON HOURS. WILL KEEP 30 PERCENT RAIN CHANCES GOING ACROSS THE MIDDLE AND UPPER KEYS. && .MARINE...REST OF TODAY...BOUNDARIES SITUATED ACROSS THE NEARSHORE GULF WATERS NORTH OF THE LOWER KEYS AND THE OFFSHORE CHOKOLOSKEE WATERS WILL SCATTERED SHOWERS AND THUNDERSTORMS THROUGH EARLY THIS AFTERNOON. ENOUGH MIDDLE LEVEL DRY AIR COULD ALLOW FOR ISOLATED WIND GUSTS OVER 35 KNOTS WITHIN THESE SHOWERS AND STORMS. DURING THE AFTERNOON...SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL FIRE WITHIN THE KEYS CUMULUS LINE AND ADDITIONAL SHOWERS AND THUNDERSTORMS MAY MIGRATE SOUTHWEST FROM SEA BREEZE GENERATED CONVECTION OVER THE EXTREME SOUTHERN TIP OF THE PENINSULA. AS A REMINDER SPECIAL MARINE WARNINGS WILL BE ISSUED WHEN RADAR INDICATES THAT ISOLATED WIND GUSTS EXCEEDING 35 KNOTS ARE LIKELY. IN ADDITION...CONDITIONS WILL BE SOMEWHAT FAVORABLE FOR WATERSPOUT DEVELOPMENT. MARINERS SHOULD ALSO LOOK FOR WATERSPOUTS THAT FORM ALONG THE EDGE OF LONG DARK FLAT CLOUD BASES. IF YOU SIGHT A WATERSPOUT...DETERMINE THE DIRECTION ITS GOING...AND MOVE IN THE OPPOSITE DIRECTION. LISTEN TO NOAA WEATHER RADIO FOR POSSIBLE MARINE STATEMENTS AND WARNINGS ISSUED BY THE NATIONAL WEATHER SERVICE IN KEY WEST. && .AVIATION...FOR THE REMAINDER OF TODAY...VFR CONDITIONS WILL PREDOMINATE AT THE KEY WEST AND MARATHON TERMINALS...WITH AN OCCASIONAL MVFR CEILING OR VISIBILITY POSSIBLE IN A SHOWER OR THUNDERSTORM MAINLY THIS MORNING.
