AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
421 AM CDT TUE APR 24 2007

...SEVERE THUNDERSTORMS AND HEAVY RAINFALL EXPECTED TONIGHT THROUGH
EARLY WEDNESDAY MORNING...

...FLASH FLOOD WATCH IN EFFECT FOR MOST OF SOUTH CENTRAL TEXAS
FROM TUESDAY EVENING THROUGH WEDNESDAY MORNING...

.DISCUSSION...
CLOUDY CONDITIONS ARE EXPECTED THIS AFTERNOON AHEAD OF A MAJOR
STORM SYSTEM EXPECTED TONIGHT. AN UPPER LEVEL LOW WILL TREK ACROSS
THE OKLAHOMA PANHANDLE REGION BY 00-03Z WEDNESDAY. A SQUALL LINE
IS EXPECTED TO DEVELOP ALONG THE TROF AXIS...BRINGING THE POSSIBILITY
OF SEVERE THUNDERSTORMS TO THE HILL COUNTRY BY LATE AFTERNOON. THE
SQUALL LINE WILL CONTINUE TO PROGRESS EASTWARD ACROSS THE CWA AND
IS EXPECTED TO MOVE INTO SOUTHEAST TEXAS BY NOON ON WEDNESDAY. THE
PRIMARY CONCERN WITH THESE STORMS WILL BE LARGE HAIL AND DAMAGING
WINDS...BUT ISOLATED TORNADOES ARE ALSO POSSIBLE. HEAVY RAIN IS ALSO
EXPECTED WITH THESE STORMS. AVERAGE RAINFALL ACCUMULATIONS OF ONE TO TWO
INCHES CAN BE EXPECTED BY WEDNESDAY MORNING. QPF BULLS-EYES OF TWO
TO FOUR INCHES CONTINUE TO BE DEPICTED OVER THE EASTERN HILL
COUNTRY...ALONG THE ESCARPMENT...AND ACROSS NORTHERN COUNTIES OF
SOUTH CENTRAL TEXAS. WHILE THESE AREAS ARE THE MOST LIKELY TO
RECEIVE THE HIGHEST RAINFALL TOTALS...NEARLY ALL OF SOUTH CENTRAL
TEXAS WILL BE SUSCEPTIBLE TO FLASH FLOODING PROBLEMS. GIVEN THIS
THREAT...A FLASH FLOOD WATCH IS IN EFFECT FROM TUESDAY EVENING
THROUGH WEDNESDAY MORNING FOR MUCH OF THE CWA. THE MODELS ARE IN
FAIR AGREEMENT WITH THE SYSTEM CLEARING THE CWA BY MID TO LATE
WEDNESDAY MORNING.

THE DEVELOPMENT OF RIDGING ALOFT THROUGH THE END OF THE WEEK WILL
KEEP THE REGION DRY AND WARM. TEMPERATURES WILL GENERALLY BE
WITHIN A FEW DEGREES OF LATE APRIL NORMALS. THE NEXT BEST CHANCE
FOR RAIN WILL BE LATE FRIDAY AFTERNOON AND NIGHT AS A VIGOROUS
LITTLE S/W TROUGH PASSES TO THE NORTH. FOR NOW, HAVE ONLY
MENTIONED SLT-CHC POPS FOR THE NORTHERN COUNTIES DURING THIS TIME
FRAME...BUT POPS WILL LIKELY INCREASE WITH FUTURE PACKAGES.
CONDITIONS THROUGH THE REST OF THE FORECAST PERIOD LOOK DRY AND
SEASONABLE WITH UPPER RIDGING DOMINATING THE WEATHER PATTERN.
