GULF OF MEXICO...ATLC RIDGE W EXTENSION MAINTAINS ITS PSN ALONG 
N GULF WITH MOSTLY LIGHT SE FLOW ACROSS BASIN...MODERATE OVER 
SWRN GULF AND ALONG TEXAS COAST.  HIGH PRES OVER ATLC HOLDS 
STEADY WHILE SHORT WAVE ALOFT DIGS S INTO CENTRAL TEXAS 
INCREASING PRES GRADIENT AND HENCE STRENGTHEN SE RETURN FLOW.
ADDITIONALLY...WEAK TRPCL WAVE PRESENTLY S OF 25N ALONG 88W  
WILL REINFORCE SE WINDS ONCE IT GETS PAST 93W WITHIN NEXT 24 
HRS.

WIND N OF 26N WHILE BRINGING MODERATE E FLOW S OF 26N.  RETURN 
OF WEAKENING UPPER CYCLONIC VORTEX INTO NW CORNER OF BASIN 
SHOULD BRING DIFFLUENT FLOW ALOFT OVER CENTRAL PARTS OF BASIN 
WHERE ABUNDANT TRPCL MOISTURE REMAINS...BUT LACK OF UPLIFTING 
MECHANIC WILL RESTRAIN DEVELOPMENT OF CONVECTION SINCE AIR 
REMAIN FAIRLY STABLE.
  
TRPCL ATLC AND CARIBBEAN...PLENTY OF TRPCL MOISTURE LEFT BEHIND 
BY TRPCL WAVE NOW OVER YUCATAN PENINSULA BUT UPPER LEVEL DOES 
NOT LOOK TOO FAVORABLE TO ENHANCE DEEP CONVECTION OVER BASIN. 
  
NEXT TRPCL WAVE NOW ENTERING TRPCL ATLC ALONG 56N WILL ENTER E 
CARIBBEAN TONIGHT...ALONG 65W FRI AND ALONG 70W SAT.  OTHERWISE
