AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
946 AM EST SAT DEC 26 2009

.UPDATE...
NOT PLANNING ON ANY CHANGES TO THE FORECAST THIS MORNING. SURFACE
HIGH PRESSURE CENTERED OVER THE NORTH CENTRAL GULF THIS MORNING.
PRETTY DRY ATMOSPHERE ALOFT HERE...WITH THIS MORNING'S TBW
SOUNDING SHOWING JUST A VERY SHALLOW MOIST LAYER AROUND 2-3KFT
(AS ALSO NOTED BY A CEILING ACROSS OUR NORTHERN COUNTIES) AS WELL
AS CONTINUED HIGH CLOUDS STREAMING ACROSS THE GULF. EXPECT THE
LOWER CLOUDS TO BREAK UP A LITTLE THIS MORNING...BUT PARTLY CLOUDY
SKIES CONTINUE FOR THE REST OF THE DAY. TEMPERATURES WILL REMAIN
COOL...WITH HIGHS ONLY GETTING UP TO AROUND 60 DEGREES OVER THE
NATURE COAST...MID 60S TAMPA BAY AREA AND LOWER 70S DOWN SOUTH
NEAR FORT MYERS. 

&&

.AVIATION...
HAVE MOSTLY MVFR CEILINGS IN PLACE ACROSS THE TERMINALS WITH SOME
IFR TO OCCASIONALLY LIFR VISIBILITIES WITH FOG AT RSW. THE LOW
CEILINGS SHOULD LIFT JUST ABOVE VFR OVER THE NEXT COUPLE OF HOURS
AND THE FOG AT RSW SHOULD ALSO DISSIPATE. VFR CONDITIONS SHOULD
THEN REMAIN THROUGH THE REST OF THE PERIOD.

&&

.MARINE...
NORTH WINDS AROUND 10-15KTS WILL CONTINUE TODAY. SEAS ARE STILL
PRETTY ROUGH OFFSHORE...BUT AS THE HIGH BUILDS INTO THE EASTERN
GULF THESE SHOULD START TO DIMINISH LATER THIS MORNING/EARLY THIS
AFTERNOON. 

&&

.FIRE WEATHER...WITH A FEW TWEAKS TO TEMPS AND DEW POINTS THIS
AFTERNOON...LOOKS LIKE RELATIVE HUMIDITIES SHOULD JUST BARELY GET
DOWN TO AROUND 35% OVER THE NATURE COAST. NOT LOOKING FOR THEM TO
STAY DOWN AROUND RED FLAG CRITERIA FOR MORE THAN AN HOUR OR SO
THOUGH...SO WILL LEAVE JUST A HEADLINE IN THE FIRE WEATHER
FORECAST FOR NOW. WILL CONTINUE TO MONITOR THIS AFTERNOON HOWEVER
JUST IN CASE DEW POINTS GET LOWER THAN EXPECTED.

&&

.TBW WATCHES/WARNINGS/ADVISORIES...
FL...NONE.
GULF WATERS...NONE.
