THE BIG TIME CONVECTION DEVELOPED NORTH OF CWA IN RRQ OF JET THAT
ALSO IS BEING FEED TROPICAL MOISTURE FROM EASTERN PAC TROPICAL
SYSTEM.  MOST OF CWA HAS BEEN IN AREA OF WEAK ISENT LIFT AND
MOISTURE CONVERGENCE THAT IS SETTING OFF WIDELY SCATTERED SHRA/TSRA.
IT LOOKS LIKE THE FRONT WILL ONLY MOVE TO JUST NORTH OF CWA AS SHORT
WAVE RIDGE DEVELOPS OVER WESTERN TX AHEAD SHORT WAVE TROF MOVING
INTO BAJA.  LOOKS LIKE FRONT WILL MOVE THROUGH LATE MONDAY OR MONDAY
NIGHT.  THIS LEAVES CWA IN INTERESTING SITUATION...WITH PLENTY OF
MOISTURE...THE FRONT...HIGH THETA-E AIR...ISENT LIFT...HOWEVER AT
LEAST THOUGH SUNDAY THE BEST OF ALL OF THE ABOVE REMAIN OVER HILL
COUNTRY AND IN FAR WESTERN CWA.  WILL HOLD ON ANY FFA FOR NOW AND
SEE HOW THE ATMOSPHERE READJUSTS AFTER THE CONVECTION TO NORTH.  MY
FEELING NOW IS THE NORTHERN TIER OF COUNTIES MIGHT NEED AN FFA IF
THINGS REDEVELOP OVER HILL COUNTRY AND SPREAD SOUTH TONIGHT.  WITH
ALL OF THIS SAID...MY MODEL OF CHOICE CONTINUES TO BE THE AVN BUT
WILL BLEND IN SOME ISENT DATA FROM ETA EVEN THOUGH WE HAVE SOME
DIABATIC AFFECTS GOING ON.  WILL KEEP SKIES MOCLD THROUGH PERIOD AND
WILL TREND TEMPS AND POPS TOWARDS FAN GUIDANCE. HOWEVER FAN MAY BE A
BIT TOO LOW FOR MINS AND WILL BUMP THOSE UP.
