Lightning Strike in Florida, June 9, 2010

AREA FORECAST DISCUSSION FOR THE FLORIDA KEYS
NATIONAL WEATHER SERVICE KEY WEST FL
335 PM EDT WED JUN 9 2010

.DISCUSSION...
DURING THE COURSE OF TODAY...SEVERAL CLOUD LINES HAVE DEVELOPED OVER
THE UPPER KEYS RESULTING IN PERIODIC EPISODES OF SHOWERS WITH ONLY A
FEW SHOWERS OCCURRING IN THE MIDDLE KEYS. CURRENTLY...SKIES ARE
PARTLY CLOUDY WITH EAST TO SOUTHEAST WINDS OF 5 TO 10 MPH ALLOWING
TEMPERATURES TO HOVER AROUND 90 DEGREES. SURFACE WISE...A SUBTLE
TROUGH LIES FROM JUST EAST OF THE UPPER KEYS SOUTHWARD INTO THE
STRAITS...WHILE A WEAK WESTERN ATLANTIC RIDGE EXTENDS INTO THE
EXTREME SOUTHEAST UNITED STATES AND NORTH FLORIDA. ACROSS OUR MARINE
DISTRICT...C-MAN STATION PLATFORM OBSERVATIONS INDICATE EAST TO
SOUTHEAST WINDS OF 5 TO 10 KNOTS...EXCEPT NORTHEAST AT 10 TO 15
KNOTS IN AND AROUND PULASKI SHOAL LIGHT AND MOLASSES REEF LIGHT.
MEANWHILE...LOCAL RADARS ARE DETECTING WIDELY SEPARATED SHOWERS ON
THE WATERS SURROUNDING THE MIDDLE AND UPPER KEYS...WITH A FEW
SHOWERS IN AND AROUND DRY TORTUGAS.

.SHORT TERM (TONIGHT THROUGH SATURDAY NIGHT)...
WITH THE CENTER OF A DEEP ANTICYCLONE HOLDING IN THE EXTREME
SOUTHEAST UNITED STATES...A COUPLE OF MID AND UPPER LEVEL SHORT WAVE
TROUGHS WILL ROTATE AROUND AND SOUTHEASTWARD INTO THE WESTERN
ATLANTIC...OFFSHORE OF THE FLORIDA EAST COAST. BECAUSE OF THIS...A
WEAK WESTERN ATLANTIC RIDGE WILL REMAIN ACROSS THE NORTHERN PORTION
OF THE FLORIDA PENINSULA.

PRECIPITATION WISE...
WITH STRONG SUBSIDENCE LYING WELL NORTHWEST AND UPWARD LIFT TO OUR
NORTHEAST...MESOSCALE INTERACTIONS WITHIN A NEUTRAL UPPER LEVEL
ENVIRONMENT WILL BE DOMINANT. WITH THAT IN MIND...FORECAST SOUNDINGS
REVEAL A FAIRLY FAVORABLE WIND PROFILE IN THE LOW AND MID LEVELS TO
ALLOW CLOUD LINE GENERATION...WITH OUTFLOW BOUNDARIES FROM SOUTH
FLORIDA AND ANDROS ISLAND POSSIBLE. HENCE...LOW CHANCE POPS WILL BE
CARRIED INTO THIS WEEKEND...WITH DAYTIME HIGHS NEAR 90 AND OVERNIGHT
LOWS IN THE LOWER 80S OUTSIDE OF RAINFALL.

.LONG TERM (SUNDAY THROUGH WEDNESDAY)...
LITTLE CHANGE IN THE SYNOPTIC SCALE...AS OUR REGION WILL LIE ON THE
SOUTHERN PERIPHERY OF A DEEP LAYERED RIDGE OVER THE EXTREME
SOUTHEAST UNITED STATES AND NORTHERN FLORIDA. DESPITE AN ABSENCE OF
A LOW LEVEL UNDULATION OR LARGE SCALE LIFT...PLENTY OF LOW LEVEL
MOISTURE WITHIN A MODEST EASTERLY FLOW WILL PROVIDE TYPICAL CLIMO
LOW CHANCE POPS ALONG WITH NEAR NORMAL TEMPERATURES THROUGH THE
PERIOD.

&&

.MARINE...
OUTSIDE OF SHOWERS AND THUNDERSTORMS...LIGHT TO GENTLE WINDS WILL
PREDOMINATE ON KEYS WATERS THROUGH FRIDAY BEFORE WINDS INCREASE A
TAD INTO THE GENTLE MODERATE RANGE THIS WEEKEND. HENCE...NO EXERCISE
CAUTION STATEMENTS OR ADVISORIES ARE ANTICIPATED.

&&

.AVIATION...
ISLAND CLOUD LINES MAY CONTINUE TO DEVELOP THROUGH THE REMAINDER OF
THIS AFTERNOON INTO EVENING ALONG THE MIDDLE AND LOWER
KEYS...RESULTING IN BRIEF PERIODS OF MVFR CEILINGS. THERE IS A LOW
CHANCE THAT BRIEF MVFR VISIBILITIES WILL BE POSSIBLE SHOULD SHOWERS
DEVELOP. OTHERWISE...VFR CONDITIONS WILL PREVAIL. SURFACE WINDS WILL
BE LIGHT THROUGH THIS EVENING...BECOMING EAST TO SOUTHEAST AT 5 TO
10 KNOTS OVERNIGHT.
