DISCUSSION...
THE WEAK FRONTAL/OUTFLOW BOUNDARY OVER THE SOUTHERN ZONES APPEARS
TO BE WASHING OUT THIS AFTN. NOT A LOT (IF ANY) DEVELOPMENT NOTED
SO FAR AND IT DOES LOOK LIKE THE CAP IS HOLDING.

NOT A LOT OF CHANGES WITH THIS NEXT FCST PACKAGE AS SE TX SEEMS TO
BE SETTLING INTO OUR MORE NORMAL SUMMERTIME PATTERN WITH THE PERS-
ISTENT LOW-LEVEL ONSHORE FLOW COMBINED WITH UP RIDGING ALOFT. THIS
RIDGE IS PROGGED TO BREAKDOWN EARLY NEXT WEEK AS A SERIES OF SHORT
WAVES PUSH ACROSS THE SRN PLAINS THESE NEXT COUPLE OF DAYS. WHILST
THE TRACKS OF THESE DISTURBANCES ARE EXPECTED TO REMAIN WELL NORTH
OF THE REGION...THE TAIL END OF THESE SYSTEMS COULD EFFECT THE FAR
NRN PARTS OF OUR CWFA FRI/SAT. THUS NO REAL ARGUMENTS WITH THE LOW
POPS ALREADY IN THE GRIDS FOR THIS TIMEFRAME. OTHERWISE...A MOSTLY
DRY (POPS NOT RH) FCST WITH TEMPS AT (AROUND) SEASONAL NORMS THESE
NEXT SEVERAL DAYS. 41
