CURRENTLY: 88D AND VIS SAT LOOP SHOWING CONVECTION DEVELOPING OVER
THE INTERIOR SCENT FA...NEAR THE LAKE. STILL RELATIVE LACK OF CU
OVER THE WEST CENTRAL AND N FA...POSSIBLY DUE TO SOME SUBSIDENCE ON
WEST SIDE OF WEAK INVERTED TROF OVER SE FL.

REST OF TODAY: EXPECT TSTMS TO CONTINUE DEVELOPING OVER THE INTERIOR
SCENT AND SW FA...THEN SLOWLY EXPAND NORTHWARD. WITH SLIGHTLY DRIER
AIR OVER THE N AND WESTERN CENT FA...COVERAGE SHOULD BE LESS THAN
THE SOUTH AND INTERIOR. TSTMS WILL LIKELY LAST WELL INTO THE
EVENING.

DISC: MODELS NOT INTIALIZING INVERTED SFC TROF OVER SE FL VERY
WELL...WHICH LOWERS MY CONFIDENCE IN THE MODEL FCSTS. HOWEVER...ETA
DOES SEEM TO CAPTURE THIS INVERTED TROF IN A WEAK SENSE...AND MOVES
IT WNW INTO THE GULF LATER TONIGHT. LOOKING AT LATEST SAT/RADAR
LOOPS...THIS SEEMS REASONABLE. SFC RIDGE AXIS...CURRENTLY OVER THE

FURTHER SOUTH INTO THE CENT FA BY SAT. WEAK EASTERLY LOW LEVEL FLOW
WILL ALLOW FOR AFTN WEST COAST SEABRZS THROUGH THE PERIOD. STEERING

REMAIN WEAK SW THROUGH FRI...THEN MAYBE MORE ENE ON SAT. IN GENERAL
...MODELS SEEM TO KEEP HIGHEST MOISTURE/PWS OVER THE INTERIOR SCENT
AND SW FA...WHICH IS WHERE HIGHEST POPS WILL REMAIN IN FCST. NOT
PLANNING TO GO MUCH HIGHER THAN 30-40% POPS FOR WEST CENT AND N FA...
AND WILL KEEP 40-50% POPS INTERIOR AND SW FA THROUGH THE PERIOD.
FWC/FAN TEMPS REASONABLE.
