SYNOPSIS...
A BROAD AREA OF HIGH PRESSURE ALOFT WITH A MOIST ATMOSPHERE WILL
CONTINUE FOR THE NEXT SEVERAL DAYS. THE BORDERLAND IS LIKELY TO SEE
SCATTERED THUNDERSTORMS THROUGH THE WEEKEND. WITH THE MOIST
ATMOSPHERE IN PLACE...SOME OF THESE THUNDERSTORMS COULD PRODUCE SOME
HEAVY SHOWERS. TEMPERATURES WILL REMAIN NEAR OR SLIGHTLY BELOW
NORMAL AS CLOUD COVER WILL REDUCE DAYTIME HEATING.

DISCUSSION...
FAIRLY HIGH MOIST ATMOSPHERE REMAINS IN PLACE TODAY WITH PWS THAT
ARE AROUND 120-150% OF NORMAL...AND MODELS STILL SHOWING HIGH PRECIP
EFFICIENCY VALUES OVER MOST OF CWA. LOOK FOR SCATTERED THUNDERSTORMS
AGAIN TONIGHT WITH LOCAL HEAVY SHOWERS. ONLY READILY APPARENT CHANGE
FROM YESTERDAY...ETA/AVN/RUC ALL SHOWING SURFACE CONVERGENCE ZONE
SHIFTING TO THE EAST TONIGHT AS LIGHT WEST WINDS SPREAD ACROSS MUCH
OF THE AREA.

MID TERM...BOTH ETA/AVN SHOWING RIDGE OVER CWA NOW CONNECTED TO GULF
OF MEXICO HIGH WITH WEAK PERSISTENT VORT LOBE EAST-WEST THROUGH THIS
RIDGE ACROSS NORTHERN PORTION OF CWA. BOTH MODELS SHOW THIS LOBE
PERSISTING THROUGH FRIDAY AND SATURDAY. WITH SEASONALLY HIGH PWS
CONTINUING AND NOT MUCH IN THE WAY OF FOCUSING...WILL KEEP SCATTERED
THUNDERSTORM WORDING IN FORECAST THROUGH THIS PERIOD.

AVN SHOWS BY SATURDAY NIGHT AND SUNDAY THE LARGE RIDGE OF HIGH
PRESSURE BECOMES MORE EAST-WEST AND LINKS UP WITH BAJA HIGH. THE
PESKY VORT LOBE THEN ORIENTS NORTH-SOUTH THROUGH THE MIDDLE OF THIS
RIDGE...RIGHT OVER THE CWA...AND PERHAPS GETS SOME REINFORCEMENT
FROM WEAK EASTERLY WAVES. HARD TO PUT ANY SPATIAL RESOLUTION IN THIS
PATTERN SO FOR NOW WILL JUST KEEP THE SCATTERED THUNDERSTORMS IN FOR
THE DURATION OF THE EXTENDED. TEMPERATURES SHOULD REMAIN AT OR
SLIGHTLY BELOW NORMAL AS SIGNIFICANT CLOUD COVER WILL HINDER DAYTIME
HEATING.
