.DISCUSSION...
SUBSIDENCE APPARENT ON WV THIS MORNING AS UPPER RIDGE AXIS
FORECAST TO REMAIN OVER TX THROUGH MONDAY. PATCHY LIGHT FOG
POSSIBLE AROUND SUNRISE FOR MAINLY THE NORTHERN HALF OF THE
REGION. ISOLATED SHOWERS DOTTING THE AREAS MAINLY SOUTH OF THE
I-10 CORRIDOR.

RAIN CHANCES OF 20 TO 40 PERCENT TODAY BUT WITH SUBSIDENCE ALOFT
EXPECTING MOST CONVECTIVE DEVELOPMENT TO BE SHOWERS WITH ONLY AN
ISOLATED THUNDERSTORM OR TWO THIS AFTERNOON AND PROBABLY ALONG THE
SEABREEZE. BEST CHANCES FOR RAIN ACROSS THE SOUTH THIS MORNING.
THIS DAILY PATTERN OF SHOWERS NEAR THE COAST IN THE MORNING
SHIFTING INLAND WILL REPEAT EACH DAY THROUGH THE WEEKEND...WITH
SLIGHTLY LOWER RAIN CHANCES THROUGH SUNDAY. TEMPERATURES WILL BE
CREEPING UP AND SUNSHINE SHOULD BE ON THE INCREASE AS WELL AS
MOISTURE LEVELS DECREASE. A PLEASANT AND WARMER THAN NORMAL LABOR
DAY WEEKEND IS IN THE OFFING.

RAIN CHANCES START TO RECOVER WEDNESDAY AND THURSDAY AS A COLD
FRONT (MODELS DIFFERING ON STRENGTH AND TIMING) SAGS SOUTH INTO
THE REGION. WARM DAYS MONDAY AND TUESDAY BEFORE CLOUD COVER AS
STREAM OF PACIFIC MOISTURE ARRIVES OVERHEAD COMBINED WITH THE
FRONTAL BOUNDARY WHICH HAS PROMPTED AN INCREASE TO RAIN CHANCES
FOR WEDNESDAY-FRIDAY NEXT WEEK. PATTERN MAY EVEN SUPPORT A DAY OF
HEAVY RAIN THREAT BUT TOO EARLY TO HAVE MUCH CONFIDENCE YET.
