WEST CENTRAL AND SOUTHWEST FLORIDA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY AREA - RUSKIN FL
112 PM EDT THU JUN 14 2001

A FAIRLY ACTIVE AFTERNOON UPCOMING...SO WILL KEEP THIS BRIEF.
LITTLE CHANGE TO THE CURRENT THINKING FOR THE NEXT SEVERAL DAYS...
WITH THE SHORT TERM FCST HINGING SOMEWHAT ON THE MOVEMENT/STRENGTH OF
THE SUBTROPICAL LOW IN NC AND LONGER TERM THE HOPEFUL GENERATION OF
SOME E/SE FLOW.

MODELS ARE SHOWING SIMILAR TRENDS TO WED...THAT IS THE ETA IS
STRONGEST AND MOST PERSISTENT WITH THE SUBTROPICAL LOW...THE NGM
LOSES IT FAIRLY QUICKLY...AND THE AVN MOVES IT ALONG A BIT TOO
QUICK.  WILL LEAN TOWARD THE ETA SOLUTION ONCE AGAIN.

SHORT TERM:
LIGHT STEERING FLOW SHOULD KEEP CONVECTION GOING INTO THE EARLY
EVENING...ESP CENTRAL AND S.  THE IMMEDIATE COAST SHOULD REMAIN
DRY...BUT INLAND COASTAL COS FROM HILLSBOROUGH S MAY SEE PULSE
DEVELOPMENT ALONG OLD PROPAGATING BOUNDARIES.  WILL CARRY AN EARLY
EVENING PERIOD FOR ONGOING ACTIVITY.

OTHERWISE...THINGS QUIET DOWN QUICKLY AROUND SUNSET.  EXPECT SOME
EARLY AM TOWERS NEAR THE COAST AND WILL HANDLE IN MARINE...
OTHERWISE MOSTLY CLEAR TONIGHT.  FRI...MODEL SOUNDINGS NOT TOO DIFF
FROM TODAY...WITH LIS NEAR -11 ONCE AGAIN.  ONE DIFF IS STORM
MOTION...WHICH WILL BE A BIT FASTER AND ORIENTED FROM NW TO SE.  SUCH
FLOW COMBINED WITH H85 TEMPS NEAR 18C SHOULD CRANK INLAND TEMPS TO
THE MID 90S.  WILL CONTINUE WITH LESSER PCPN CHANCES TOWARD THE
COAST AND HIGHER INLAND.

NW FLOW ESTABLISHES FRI NIGHT...BUT IS ALSO AHEAD OF MID LEVEL SHORT
WAVE AROUND TAIL OF UPPER LOW.  THE COMBINATION MAY ALLOW A BIT MORE
ACTION NEAR THE COAST TOWARD DAYBREAK AND WILL INTRODUCE SLIGHT
CHANCES HERE.  NW-SE STORM MOTION INCREASES SAT AND THIS SHOULD
SCOOT ACTIVITY WELL INLAND...REACHING THE E COAST LATE IN THE DAY.

EXTENDED:
WIND SHIFT BOUNDARY SNEAKS INTO THE CENTRAL CWFA SUN AND PARKS...
LIGHTENING WINDS AND ALLOWING FOR SEA BREEZE COLLISIONS ONCE
AGAIN.  THE BOUNDARY WASHES OUT LATE SUN/MON...AND SLOWLY BUILDING
SFC HIGH TO OUR N WILL ESTABLISH AT LEAST A LOW LVL ESE FLOW FOR MID
WEEK.  WILL GO BACK TO AFTN/EVE TSTMS IN THE LATTER EFP WITH
SEASONABLE TEMPS.

MARINE:  QUIET OUTSIDE OF ANY MORNING TSTMS THROUGH THE WEEKEND.

FIRE WX:  NO HIGHLIGHTS GIVEN HIGH RH VALUES AND LIGHT WINDS.
