SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE HOUSTON TX
4 PM CDT WED MAY 31 1995

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS ALL OF
SOUTHEAST TEXAS TONIGHT THROUGH THURSDAY EVENING.  THE CITIES OF
HOUSTON...BRYAN...COLLEGE STATION AND GALVESTON ARE INCLUDED IN THE
RISK AREA.

AN UPPER LEVEL DISTURBANCE MOVING ACROSS A WEAK STATIONARY FRONT HAS
LEAD TO THE DEVELOPMENT OF STRONG THUNDERSTORMS OVER NORTH TEXAS THIS
AFTERNOON.  AS THIS SYSTEM MOVES SOUTH INTO THE AREA...STRONG
THUNDERSTORMS ARE EXPECTED TO DEVELOP LATER THIS EVENING OVER
SOUTHEAST TEXAS.  WITH THIS AFTERNOON'S HEATING...THE ATMOSPHERE OVER
SOUTHEAST TEXAS HAS BECOME QUITE UNSTABLE AND SHOULD BE SUFFICIENT
FOR THE STORMS TO BECOME SEVERE.

THE MAIN THREAT WITH THESE SEVERE THUNDERSTORMS WILL BE LARGE HAIL
AND DAMAGING WINDS.

TOMORROW...ANOTHER SERIES OF UPPER LEVEL DISTURBANCES WILL BE MOVING
THROUGH THE AREA.  WITH THE ATMOSPHERE REMAINING RELATIVELY UNCHANGED
- MOIST AND UNSTABLE...ANOTHER ROUND OF SEVERE WEATHER IS POSSIBLE
THURSDAY INTO THURSDAY EVENING.
