COASTAL BEND FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
1010 AM CDT TUE MAY 2 2000

CONVECTION CONTINUES TO MOVE THROUGH THE CWA THIS MORNING. 88-D AND
SAT ARE INDICATING SOME ADDITIONAL DEVELOPMENT OVER SW WEBB COUNTY.
OUTFLOW FROM MORNING STORMS HAS MOVED SOUTH OF MOST OF THE CWA. TAIL
END OF OUTFLOW IS OVER SOUTHERN DUVAL AND JIM WELLS...AND SW
WEBB...WHICH IS AIDING LIFT IN THAT AREA.

A SECOND OUTFLOW IS MOVING SOUTH ACROSS NORTHERN WEBB FROM
CONVECTION TO THE NORTH. THIS SHOULD ENHANSE CONVECTION THROUGH THE
MORNING HOURS. CONCERN FOR THE DAY WILL FOCUS ON HEAVY RAINFALL
AMOUNTS. TRAINING IS OCCURING OVER SOUTHERN DUVAL...AND WILL HAVE TO
WATCH THE SOUTHERN CWA CLOSELY FOR LOCALIZED FLOODING. AN URBAN
SMALL STREAM ADV CONTIUES THROUGH NOON FOR THOSE AREAS. WET BULB ZERO IS
QUITE HIGH...THEREFORE HAIL IS NOT THE PRIMARY CONCERN.

CURRENT FORECAST APPEARS GOOD...AND WILL MAKE NO CHANGES AT THIS
TIME. HOWEVER...MAY SHAVE DOWN POPS IN WEBB AND MCMULLEN...IF
CONVECTION BEGINS TO CLEAR IN THOSE AREAS. SECOND PERIOD POPS WILL
NEED TO BE REEVALUATED IF THE CONVECTION CONTINUES TODAY...AND
STABLIZES THE ATMOSPHERE.
