THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE OKLAHOMA CITY OK
1235 PM CDT SUN MAY 29 1994

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
TONIGHT ACROSS THE WESTERN HALF OF OKLAHOMA AND THE WESTERN PART OF
NORTH TEXAS. THE SLIGHT RISK AREA IS GENERALLY WEST OF A LINE FROM
ENID... TO OKLAHOMA CITY... TO LAKE TEXOMA.

THE BEST CHANCE FOR SEVERE THUNDERSTORMS WITHIN THE SLIGHT RISK AREA
WILL BE IN SOUTHWEST OKLAHOMA AND WESTERN PART OF NORTH TEXAS.

SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON IN THE
WESTERN PORTIONS OF OKLAHOMA AND NORTH TEXAS. SOME OF THE THUNDERSTORMS
MAY MOVE INTO CENTRAL SECTIONS OF OKLAHOMA THIS EVENING. LARGE HAIL...
DAMAGING WINDS... AND ISOLATED TORNADOES WILL BE POSSIBLE WITH THE MOST
INTENSE STORMS.

THUNDERSTORMS THAT OCCURRED LAST NIGHT AND THIS MORNING HAVE GENERATED
AN OUTFLOW BOUNDARY THAT EXTENDED FROM ALTUS TO NEAR ARCHER CITY AT
MIDDAY. THE BOUNDARY WILL SERVE AS A POSSIBLE FOCUS FOR THE DEVELOPMENT
OF STRONG THUNDERSTORMS DURING THE AFTERNOON. MEANWHILE... THE AIRMASS
IS EXPECTED TO BECOME VERY UNSTABLE IN SOUTHWEST OKLAHOMA AND THE
WESTERN PART OF NORTH TEXAS DURING THE AFTERNOON.

VERTICAL WIND PROFILES ARE EXPECTED TO BE ADEQUATE FOR THE DEVELOPEMENT
OF SUPERCELL THUNDERSTORMS... ESPECIALLY IF THE THUNDERSTORM BOUNDARIES
ARE MAINTAINED THROUGH THE AFTERNOON.

AN AREA OF WEAK SURFACE CONVERGENCE IN NORTHWEST OKLAHOMA MAY ALSO HELP
TO TRIGGER SCATTERED STRONG THUNDERSTORMS THIS AFTERNOON AND EVENING.

PERSONS ENGAGED IN OUTDOOR ACTIVITIES THIS HOLIDAY WEEKEND SHOULD KEEP
ABREAST OF DEVELOPING WEATHER CONDITIONS... AND AVOID BEING CAUGHT IN
EXPOSED OPEN AREAS... SUCH AS LAKES... DURING A THUNDERSTORM.

SPOTTER ACTIVATIONS MAY BE REQUIRED THIS AFTERNOON IN WESTERN PORTIONS
OF OKLAHOMA AND NORTH TEXAS... AND LATER THIS EVENING IN PORTIONS OF
CENTRAL OKLAHOMA.
