AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY-RUSKIN, FL
221 PM EST THU NOV 13 1997

ONGOING CONVECTION TRAINING ACROSS THE CENTRAL PNSULA SEEMS TO BE
SLIDING ONLY VERY SLOLY SWD BUT WOULDNT BE SURPRISED IF ITS SWD
PROGRESS HAS JUST ABOUT STALLED. STALLING IN RESPONSE TO FALLING
PRESSURES BACK TO NEW ORLEANS AND THE CNTRL GOMEX IN ADVANCE OF COLD
FNT AND STRONG 5H VORT MAX PUSHING EWD OUT OF TX. ONGOING SEMI-TRAINING
BAND OF CONVECTION HAS PRODUCED SOME 1-3 INCH RAINFALL AMOUNTS WITH
LOCALIZED AMOUNTS OF 5 INCHES...MAINLY IN THE COASTAL COUNTIES FROM
LEVY SWD TO SARASOTA.

STILL BELIEVE THERE WILL BE SOME SLOW DECREASE IN AREAL COVERAGE OF
THE PRESENT CONVECTION LATE THIS AFTN INTO EARLY TNGT. BUT WITH
RENEWED ENERGY PRESSING EWD WITH FRNT AND 5H VORT...BELIEVE THERE
WILL BE SIGNIFICANT REGENERATION OF SHWRS/TSTMS IN ERN GOMEX TNGT
WITH THE ACTIVITY PUSHING SEWD THRU NRN HLF FA LATE TNGT INTO FRI
MRNG...AND SRN FA MRNG/ERLY AFTN FRI. HAVE COORD A PSBL FLOOD WATCH
WITH MIA FOR COASTAL COUNTIES INTO TNGT WITH RENEWED HVY RAIN...BUT
COORD DECISION WILL NOT BE MADE UNTIL ISSUANCE OF 5PM ZFP.

BELIEVE PCPN WILL END FROM N TO S OVER FA FRI AS COLD FNT PUSHES SEWD
DURING THE DAY. DRIER/COOLER AIRMASS TO PUSH INTO FA FOLLOWING FNT
WITH A FOLLOW UP COLDER AIRMASS FNT TO PUSH IN BY LATE SATURDAY.

AM STILL NOT CONCERNED WITH ANY PSBL COASTAL TIDAL PROBLEMS
WITH TIDAL WATERS AVERAGING ONLY 1-1.5 FT ABOVE BELOW NORMAL6
ASTRONOMICAL TIDES...SO OVERALL TIDAL WATERS SHOULD REMAIN BELOW 3 FT
MSL EVEN AS WINDS VEER TO SW AND WLY ON FRI BUT THE GRADIENT WKNS.
