WEST CENTRAL AND SOUTHWEST FLORIDA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY AREA - RUSKIN FL
115 PM EST TUE MAR 26 2002

PERHAPS A BIT OF ROUGH WX THIS AFTN AND EVENING...THEN BACK TO
SPLENDID SPRING WX ACROSS THE PENINSULA...ESPECIALLY THU/FRI WHEN
COMFORTABLE HUMIDITY RETURNS...SPELLING SUNNY WARM DAYS AND CLEAR
REFRESHING NIGHTS.

NO REAL DISCREPANCIES BETWEEN THE MODELS THIS GO-ROUND...AND RUN-TO-
RUN CONSISTENCY FOR BOTH SHORT AND MEDIUM RANGE PROVIDES STRONG
CONFIDENCE IN FCST.

SHORT TERM:
WILL ONCE AGAIN BREAK OFF AN EVENING PERIOD TO HANDLE EXPECTED
CONVECTION.  CURRENT FCST OF HIGHEST CHC INLAND STILL ON TARGET...AS
SEA BREEZE COLLISIONS/BOUNDARY COLLISIONS AND UPPER ENERGY LINK UP
AROUND 00Z.  THE OTHER AREA TO KEEP AN EYE ON IS LEVY CO...CLOSEST
TO THE ENERGY/DEEP MOISTURE ALONG TROUGH LINE.  EXPECT PCPN TO
QUICKLY EXIT THE COASTAL COS BEFORE OR JUST AFTER DARK...THEN OVER
INLAND AREAS BY MID TO LATE EVENING.

THEREAFTER...ONLY COSMETIC CHANGES TO THE PACKAGE.  LIKE THE IDEA
OF FOG AS SFC WINDS BEHIND TROUGH WILL BE LIGHT OVERNIGHT AND
RESIDUAL MOISTURE WILL BE PLENTIFUL.  WILL CONTINUE PATCHY WORDING...
THOUGH EVE SHIFT MAY WANT TO HIT HARDER IN UPDATE.  FOR WED...WILL
RELUCTANTLY HOLD ONTO VERY LOW PCPN CHC INTERIOR AND SW AS LOW LVL
MOISTURE STILL AVAILABLE AND SEA BREEZE CONVERGENCE NOT OUT OF THE
QUESTION.  A COOL DRY WED NIGHT FOLLOWED BY A SUNNY THURS WITH
TEMPS A TAD ABOVE SEASONAL LEVELS.

EXTENDED:
NO SIGNIFICANT CHANGES PLANNED TO THE PACKAGE.  A GRADUAL MOISTENING
OF THE AIR MASS SATURDAY AND SUNDAY.  NOT VERY CONFIDENT OF PCPN
SUNDAY AS DEEP DRY AIR REMAINS.  PREFER TO STAY ON THE OPTIMISTIC
SIDE AND WILL PULL MENTION.  FOR MON/TUE...STILL APPEARS TO BE SMALL
CHANCES OF PCPN AS DYING FRONT SLIDES THROUGH.  TEMPS THROUGH THE
PERIOD 2-4 DEG ABOVE NORMAL.

MARINE:
WITH WED FRONT LOOKING EVEN MORE PALTRY WILL BACK OFF A CATEGORY
FOR WIND SPEED FCST.  THAT MEANS A QUIET TIME RIGHT INTO THE
WEEKEND...OUTSIDE OF ANY EVENING ACTIVITY TODAY.

FIRE WX:
NO PROBLEMS THROUGH WED...THOUGH RH VALUES SHOULD DROP A BIT DURING
THE AFTERNOON.  DRIER AIR STILL EXPECTED TO LOWER RH AND RAISE
MIXING HEIGHTS BOTH THURS AND FRI.
