GOOD WAA ON WARM FNT TO THE NW. THIS IS HELPING TO KEEP GENERATING
TSTMS TO THE NW WHICH ARE RIDING THE FLOW SE INTO THE NW PART OF THE
AREA. GOOD HVY RN MOVG INTO THAT AREA FM DYING MCS BUT MORE TSTMS
COMING SO WL HAVE TO MONITOR THAT AREA FOR FLASH FLOOD POTENTIAL.

ELSEWHERE WARM AIR RAPIDLY ARRIVING AS WITNESSED BY DEWPOINTS PUSHING
INTO THE 70S. STILL HAVE PLENTY OF TSTMS DEVELOPING IN THE WARM SECTOR
TO THE W AND SOME OF THESE SHD MOVE E INTO THE AREA LATE THIS AFTN AND
TNGT. PLUS THE DYING MCS WL HELP GIVE A BOUNDARY TO AIDE MORE
CONVECTION THIS AFTN. THE ONLY DRAW BACK IS THAT THE CAPES ARE STILL
LOW THIS AFTN AND WL NOT BE COMING UP UNTIL MON MIGHT LIMIT SOME
CONVECTION.

WL LOWER TEMPS SOME AS CLDS SHD HOLD TEMPS DOWN. HOWEVER FAIRLY STRG
WAA SO SHD STILL BE SOME RISE IN TEMPS BACK INTO THE 80S.
