WEAK IMPULSES EMBEDDED IN THE NW FLOW ALOFT IS INTERACTING WITH A
WARM...MOIST AND MODERATELY UNSTABLE AIRMASS TO PRODUCE SOME SCT
SHWRS/TSTMS OVER THE NORTHERN PORTIONS OF THE CWA AT THIS TIME.
ALTHO THE STRONGER STORMS SHUD RMN WELL TO THE NORTH AS THE INFLUENCE
OF THE MID LVL RIDGE SHUD HINDER THE THREAT HERE...CANNOT RULE
OUT THE ISOLATED STORM PULSATING SVR LATER THIS AFTN WITH THE MAIN
THREAT BEING LARGE HAIL AND PSBLY SOME STRONG DOWNBURST WINDS. THIS
ACTIVITY WILL MOVE TO THE SSE AND LIKELY PERSIST INTO THE EVENING
HOURS BEFORE DISSIPATING WITH LOSS OF AFTN HEATING.

AS FOR THE FCST...MODELS CONTINUE TO BUILD THE UPR LVL RIDGE CRNTLY
OVER THE WRN GULF NEWD OVER THE FCST AREA ON FRI.  THEN THE MORE
AGGRESSIVE AVN SHOWS A DEEPENING UPR LVL TROF OVER THE ERN GULF IN
RESPONSE TO BUILDING RIDGES...THE ONE OVER THE WRN GULF AND ANOTHER
OVER THE ERN CARIBBEAN...WHICH SEEMS REASONABLE AT THIS TIME.  WILL
CONTINUE WITH WX PATTERN OF WIDELY SCT AFTN/EVNG TSTMS THRU THE
PERIOD WITH AFTN HTG AND WEAK IMPULSES EMBEDDED IN THE NW FLOW BEING
THE MAIN TRIGGER ON FRI AND THEN THE AFOREMENTIONED DEEPENING TROF
OVER THE ERN GULF COUPLED WITH THE SEA BREEZE RESULTING IN MORE TSTM
DEVELOPMENT AGAIN BY SAT AFTN.  NUMERICAL GUIDANCE TEMPS ARE SIMILAR
AND LOOK REASONABLE SO WILL NOT STRAY FAR.

OVER THE COASTAL WATERS...PERSISTENT RIDGE OF HIGH PRES WILL KEEP
WINDS MAINLY LIGHT AND VARIABLE WITH SEAS 2 FT OR LESS THRU SAT.
