         ...THUNDERSTORMS DEVELOPING IN THE HILL COUNTRY...

A LINE OF THUNDERSTORMS WAS DEVELOPING OVER PORTIONS OF THE EDWARDS
PLATEAU AND TEXAS HILL COUNTRY THIS AFTERNOON.  A WELL-ORGANIZED UPPER
LEVEL DISTURBANCE OVER NORTHERN MEXICO IS RAPIDLY APPROACHING SOUTH
TEXAS AND IS HELPING TO FUEL THE DEVELOPMENT OF THESE THUNDERSTORMS.

AT 430 PM CST...NATIONAL WEATHER SERVICE RADAR INDICATED THE LINE
EXTENDING SOUTHWARD FROM JUST NORTH OF LOMA ALTA TO NEAR DEL RIO IN
EASTERN VAL VERDE COUNTY.  MOVEMENT WAS NORTHEAST AT NEAR 30 MILES AN
HOUR.

ALREADY...REPORTS OF PEA-SIZE HAIL HAVE BEEN RECEIVED FROM LOCATIONS
IN AND TO THE WEST OF VAL VERDE COUNTY AS THE STORMS MOVED THROUGH.
IN ADDITION...WIND GUSTS OF NEAR 40 MILES AN HOUR WERE REPORTED AT THE
WEATHER OFFICE IN DEL RIO DURING THE PAST HALF HOUR WITH RAIN FALLING.
