Area forecast discussion, Aug 8, 3:45 PM CDT, 1 hour 13 minutes before
WEST CENTRAL TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
345 PM CDT FRI AUG 8 2003

CURRENT...SATELLITE IMAGERY INDICATING SOME CONVECTION BEGINNING TO
DEVELOP ACROSS WEST CENTRAL TEXAS THIS AFTERNOON. AT THE
SURFACE...TEMPERATURES ACROSS WEST CENTRAL TEXAS HAVE ONCE AGAIN
PUSHED PAST THE 100 DEGREE MARK...WITH BROWNWOOD AND SAN SABA NEAR
110.

DAYS 1-3...A SURFACE TROF CONTINUES TO SERVE AS A FOCUS FOR SHOWER
AND THUNDERSTORM DEVELOPMENT FOR THE NEXT 12 TO 24 HOURS ACROSS MUCH
OF WEST CENTRAL TEXAS. BEST POPS WILL BE ACROSS OUR SOUTHEASTERN
ZONES...WITH THE BEST MOISTURE AND INSTABILITY. MODELS DEVELOP AN
MCS ALONG THIS TROF TOMORROW NIGHT. THE CENTER OF THIS COMPLEX...AND
THUS THE BEST RAINFALL...WILL LIKELY BE EAST OF OUR AREA.
HOWEVER...OUR EAST COUNTIES MAY SEE THUNDERSTORMS WHICH PRODUCE
LOCALLY HEAVY RAINFALL. POPS DECREASE SATURDAY NIGHT AND
SUNDAY...BEFORE ANOTHER SURFACE FRONT APPROACHES THE BIG COUNTRY
FROM THE NORTH SUNDAY NIGHT. EXPECT ANOTHER ROUND OF TRIPLE DIGIT
HIGHS TOMORROW AFTERNOON ACROSS WEST CENTRAL TEXAS...BEFORE
INCREASING CLOUDS SUNDAY BRING SOME RELIEF FROM THE TRIPLE DIGITS.
MODEL MOS NUMBERS LOOK GOOD FOR OVERNIGHT LOWS TONIGHT.
HOWEVER...MOS NUMBERS AROUND 70 LOOK TOO COOL FOR OVERNIGHT LOWS
SATURDAY NIGHT AND SUNDAY NIGHT. THUS...WILL GO WITH NUMBERS CLOSER
TO PERSISTENCE FOR LOWS THOSE TWO NIGHTS.

DAYS 4-7...MODELS CONTINUE TO DEVELOP AND MOVE A SURFACE LOW INTO
NORTHEAST TEXAS BY TUESDAY AFTERNOON. THIS LOOKS REASONABLE GIVE THE
CURRENT POSITION OF THE LONGWAVE PATTERN. BEST CHANCE FOR RAIN WILL
BE ON WEDNESDAY AND THURSDAY...ESPECIALLY OVER OUR EASTERN
ZONES...GIVEN THE POTENTIAL FOR ADDED UPPER-LEVEL SUPPORT ON THOSE
TWO DAYS. STILL NOT CONFIDENT WITH MRF MOS TEMPERATURES...BELIEVE
THEY ARE TOO COOL. THUS...WILL GO WITH NUMBERS CLOSER TO SEASONAL
AVERAGES.
