WEST CENTRAL TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
320 PM CDT THU MAY 01 2003

CURRENT...
19Z ANALYSIS SHOWS THE DRYLINE STRETCHING FROM NEAR CROSS
PLAINS...TO SAN ANGELO AND OZONA. A FEW SHOWERS HAVE DEVELOPED ALONG
AND SOUTHEAST OF THIS LINE. DEWPOINTS RANGE FROM AROUND 30 NORTH AND
WEST...TO THE MID 60S SOUTHEAST. A WEAK UPPER RIDGE IS BEGINNING TO
BUILD IN FROM THE WEST.

TONIGHT AND FRIDAY...
TONIGHT THE DRYLINE WILL DRIFT SLIGHTLY FURTHER SOUTHEAST...HELPING
TO TRIGGER ISOLATED STORMS GIVEN THE ABUNDANT LOW/MID LEVEL
MOISTURE. ALSO WITH CAPES RUNNING UP TO 4000J/KG AND ENOUGH
SHEAR...EXPECT A FEW OF THESE STORMS WILL BECOME SEVERE.
WITH A COLD FRONT SLIDING DOWN FROM THE NORTH AND THE DRYLINE
HANGING ON ACROSS THE SOUTHEAST COUNTIES...WILL CONTINUE WITH A
SLIGHT CHANCE OF SHOWERS ON FRIDAY. ANOTHER ROUND OF SEVERE WEATHER
COULD AGAIN AFFECT THE FURTHEST SOUTHEAST COUNTIES.

SATURDAY AND SUNDAY...
THE NEXT UPPER TROUGH BEGINS TO PUSH INTO THE WESTERN STATES ON
SATURDAY. ALSO THE FRONTAL BOUNDARY LIFTS BACK NORTH OUT OF THE BIG
COUNTRY. THIS WILL HELP TO TRIGGER A FEW SHOWERS NORTH AND EAST BY
SATURDAY AFTERNOON/NIGHT. BY SUNDAY WITH THE UPPER TROUGH LIFTING
INTO THE PLAINS...THIS WILL PUSH A LEESIDE TROUGH/DRYLINE THROUGH
WEST CENTRAL TEXAS...HELPING TO TRIGGER OFF A FEW STORMS. HOWEVER
WITH LIMITED MOISTURE...THE BEST CHANCES OF SHOWERS WILL ONCE AGAIN
BE IN THE SOUTHEAST.

MONDAY THROUGH THURSDAY...
MONDAY A STRONGER COLD FRONT PUSHES THROUGH MUCH OF THE AREA.
HOWEVER WITH AS THE UPPER SYSTEM PULLS WELL OFF TO THE
NORTHEAST...THE TAIL END OF THE FRONT WILL STALL OUT ACROSS
SOUTHWEST TEXAS. HOW FAR SOUTH THE FRONT STALLS OUT WILL DETERMINE
WHEN THE BEST CHANCES OF SHOWERS WILL OCCUR THROUGH MIDWEEK. IF IT
STALLS OUT TOO FAR SOUTH AND WEST...EXPECT ONLY A SLIGHT CHANCE FOR
LIMITED TIME FRAME AS THE FRONT LIFTS NORTHEAST. HOWEVER IF IT
STALLS OUT ALONG THE SOUTHERN AND WESTERN ZONES...THERE COULD BE A
LINGERING CHANCE OF SHOWERS THROUGH THURSDAY. FOR NOW WILL GO WITH
THE MIDDLE OF THE ROAD AND KEEP POPS MENTIONED TUESDAY INTO
WEDNESDAY.

OTHERWISE...EXPECT ABOVE NORMAL TEMPERATURES THROUGH
SUNDAY...SOUTH OF THE FRONT AND BELOW NORMAL NORTH OF THE FRONT.
NEAR TO SLIGHTLY BELOW NORMAL TEMPS CAN BE EXPECTED MONDAY
THROUGH THURSDAY.
