THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
942 PM CDT MON MAY 1 2000

...HEAVY RAINFALL EXPECTED ACROSS SOUTH TEXAS OVERNIGHT...

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS LATE THIS EVENING
AND OVERNIGHT...

THE NATIONAL WEATHER SERVICE IS MONITORING A POTENT UPPER LEVEL
STORM SYSTEM...MOVING ACROSS NORTH CENTRAL TEXAS...WHICH WILL
INCREASE THE POTENTIAL FOR SHOWERS AND THUNDERSTORMS LATE TONIGHT AND
EARLY TUESDAY MORNING.

SHOWERS AND THUNDERSTORMS HAVE ALREADY DEVELOPED OVER THE TEXAS HILL
COUNTRY MONDAY EVENING.  THESE STORMS ARE EXPECTED TO PROPAGATE
SOUTHWARD OVERNIGHT AND EARLY TUESDAY MORNING.  ALSO...ISOLATED
THUNDERSTORMS WHICH DEVELOPED OVER DEEP SOUTH TEXAS ARE MOVING
NORTHEAST TOWARD THE AREA.

ALTHOUGH THE MAIN THREAT WILL BE HEAVY RAIN...A FEW THUNDERSTORMS MAY
REACH SEVERE LIMITS WITH STRONG WINDS AND HAIL.

RAINFALL TOTALS RANGING BETWEEN 1 AND 2 INCHES ARE EXPECTED OVER
MUCH OF THE AREA.  WIDESPREAD FLOODING IS NOT ANTICIPATED...HOWEVER
TORRENTIAL DOWNPOURS FROM THUNDERSTORMS WILL RESULT IN PONDING OF
WATER ON ROADWAYS...AS WELL AS RISES ON AREA RIVERS...STREAMS AND
CREEKS.

AS THE DISTURBANCE LIFTS OUT OF THE AREA TUESDAY AFTERNOON...THE
POTENTIAL FOR THUNDERSTORMS WILL DECREASE.

RESIDENTS ARE URGED TO MONITOR THIS DEVELOPING WEATHER SITUATION.
