AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
930 AM EDT TUE JUN 4 2013

.DISCUSSION...IN THE MID AND UPPER LEVELS...THERE IS A REGIONAL
SCALE TROUGH PRESENTLY BISECTING THE CENTRAL GULF OF MEXICO...WITH
20-30 KNOT SOUTHWESTERLIES AT 250 MB ON THE RIGHT FLANK OF THIS
FEATURE ACROSS THE EASTERN GULF OF MEXICO. INTERPRETATION OF THE
AVAILABLE IR SATELLITE IMAGERY AND STREAMLINE ANALYSIS AS OF 900 AM
DOES SUGGESTS THERE IS GOOD UPPER DIFFLUENCE JUST TO THE EAST OF
THIS FEATURE OVER THE YUCATAN CHANNEL AREA.

AT THE SURFACE AND IN THE LOWER LEVELS...LATEST AVAILABLE MARINE AND
LAND SURFACE OBSERVATIONS AND TROPICAL ANALYSIS AS OF 900 AM DETAIL
A WEAK 1016-1018 MB RIDGE ANALYZED ACROSS CENTRAL FLORIDA AND THE
EAST CENTRAL GULF OF MEXICO. THERE IS A UNORGANIZED WEAK AREA OF LOW
PRESSURE AT THE SURFACE OVER THE SOUTH CENTRAL GULF OF MEXICO. THE
12Z SOUNDING AT KEY WEST WAS EXCEPTIONALLY MOIST WITH TOTAL COLUMNAR
PRECIPITABLE WATER(PWAT) AT 2.13 INCHES...AND WAS VERY UNSTABLE WITH
A FRESH TO STRONG VEERING SOUTHEAST TO SOUTH FLOW FROM THE SURFACE
UP TO 700 MB...INDICATIVE OF DECENT SPEED AND DIRECTIONAL SHEAR
MAGNITUDES...WITH 0-3 KM RELATIVE HELICITY AT 181 METERS
SQUARED/SECOND SQUARED.

.CURRENTLY...AS OF 900 AM...SKIES ARE CLOUDY ACROSS THE ENTIRE
SERVICE AREA. KEY WEST RADAR SCANS SHOW THAT LIGHT RAIN ENSHROUDS
THE ENTIRE KEYS AREA AND SURROUNDING WATERS WITH THE EXCEPTION OF
THE EASTERN MARINE ZONES OFFSHORE OF THE UPPER KEYS. RADAR ALSO DOES
DETAIL A FEW THUNDERSTORMS ACROSS THE OUTER WATERS WEST OF THE
FLORIDA STRAITS. TEMPERATURES ACROSS THE RAIN COOLED ISLANDS ARE
GENERALLY AROUND 80 DEGREES WITH DEWPOINTS IN THE MID TO UPPER 70S.
AVAILABLE C-MAN STATIONS ALONG THE FLORIDA REEF ARE RECORDING GENTLE
MOSTLY EAST WIND...AROUND 10 KNOTS...AND ISLAND SENSORS ARE NEAR 10
MPH.

.SHORT TERM (TODAY THROUGH THURSDAY NIGHT)...LITTLE MOVEMENT AND
ADDITIONAL DEVELOPMENT OF THE WEAK LOW PRESSURE OVER THE SOUTH
CENTRAL GULF OF MEXICO IS ANTICIPATED THROUGH THE REST OF THE DAY.
AS THIS FEATURE REMAINS COINCIDENT WITH THE AFOREMENTIONED MID AND
UPPER TROUGH ALSO REMAINING JUST TO THE WEST OF THE KEYS...ALL
AVAILABLE MODEL FORECAST SOUNDINGS SUGGEST THE MAINTENANCE DEEP
MOISTURE AT ALL LEVELS OF THE TROPOSPHERE THROUGH THE REST OF THE
DAY...HOWEVER WITH INCREASING LIFT...DEVELOPMENT OF HEAVY SHOWERS
AND THUNDERSTORMS IS EXPECTED ACROSS ALL OF THE KEYS AND SURROUNDING
WATERS...OUTSIDE OF CONTINUOUS WIDESPREAD LIGHT TO MODERATE RAINFALL.

SO GIVEN THE INCREASING SHEAR PROFILE MENTIONED FROM THE MORNING
SOUNDING ABOVE...AND DESPITE WEAKER LAPSE RATES OWING TO A NEARLY
SATURATED ATMOSPHERE...WILL SEE POTENTIAL FOR SOME STRONGER
THUNDERSTORMS AGAIN THIS AFTERNOON AND EVENING...WITH WIND GUSTS IN
EXCESS OF 40 KNOTS. THEREAFTER...THE POTENTIAL FOR STRONG WINDS IN
SHOWERS AND THUNDERSTORMS INCREASES TONIGHT THROUGH THURSDAY DUE TO
EXPECTED DEVELOPMENT OF EITHER TROPICAL OR NONTROPICAL LOW PRESSURE
OVER THE SOUTH CENTRAL GULF OF MEXICO. IN ADDITION...WE WILL HAVE TO
WATCH THE POTENTIAL FOR HEAVY RAINFALL ACROSS THE KEYS
TODAY...ESPECIALLY GIVEN ANTECEDENT WET CONDITIONS AND POOR DRAINAGE
CAPABILITIES IN OUR KNOWN URBAN/LOCALIZED AREAS. THESE TWO HAZARDS
ARE HIGHLIGHTED IN THE HAZARDOUS WEATHER OUTLOOK.

&&

.MARINE...OVERALL...GENTLE TO MODERATE EAST TO SOUTHEAST WINDS ARE
EXPECTED OUTSIDE OF CONVECTION...BUT EXPECT A TIGHTENING GRADIENT
THIS AFTERNOON AND TONIGHT DUE TO THE COMBINATION OF DEVELOPING LOW
PRESSURE TO THE SOUTHWEST AND WEAK RIDGING TO THE NORTH. DO
ANTICIPATE ADVISORY CONDITIONS WOULD SPREAD FROM WEST TO EAST...SO
WILL MAINTAIN CAUTIONARY HEADLINE FOR THE WESTERN FLORIDA STRAITS
AND THE THE WATERS AROUND THE DRY TORTUGAS IN THE CWF TODAY AND THE
HEADLINE FOR THE POTENTIAL OF SMALL CRAFT ADVISORY CONDITIONS
TONIGHT. OF COURSE...WINDS AND SEAS WILL BE HIGHER NEAR ROBUST
SHOWERS...THUNDERSTORMS AND GIVEN AFOREMENTIONED SHEAR
PROFILES...MARINE WARNINGS MAY BE ISSUED THIS AFTERNOON AND EVENING
FOR POSSIBLE WATERSPOUTS. REGARDLESS...MARINERS SHOULD MONITOR LATER
FORECASTS AND LISTEN TO NOAA WEATHER RADIO FOR ANY MARINE STATEMENTS
AND POSSIBLE WARNINGS

&&

.AVIATION...
DESPITE LIGHT RAINFALL...VFR CONDITIONS WILL PREVAIL AT EYW AND MTH
THIS MORNING INTO THIS AFTERNOON. MVFR OR LOWER CONDITIONS ARE
LIKELY AT EYW AND MTH FROM LATE THIS AFTERNOON INTO THIS EVENING AS
RAINFALL IS EXPECTED TO INCREASE IN INTENSITY. VFR CONDITIONS WILL
PREVAIL AT EYW AND MTH AFTER MIDNIGHT TONIGHT.

&&

.CLIMATE...
ON THIS DATE IN KEYS WEATHER HISTORY...IN 1933...THE LOW TEMPERATURE
IN KEY WEST WAS 69 DEGREES. THIS SET THE DAILY RECORD FOR MINIMUM
TEMPERATURE MEASURED IN KEY WEST ON JUNE 4TH...A RECORD WHICH STILL
STANDS 80 YEARS LATER. TEMPERATURE RECORDS AT KEY WEST DATE BACK TO
1872.
