THERE IS A HIGH RISK OF SEVERE THUNDERSTORMS TODAY AND TONIGHT IN PORTIONS OF
SOUTHERN OKLAHOMA AND NORTH TEXAS.  THE HIGH RISK IS TO THE SOUTHEAST OF A      SEMINOLE TO DUNCAN TO SEYMOUR TEXAS LINE.

SEYMOUR TEXAS.  SEVERE THUNDERSTORMS HAVE ALREADY DEVELOPED ALONG THE
DRYLINE IN NORTH TEXAS AND MOVED NORTHEASTWARD INTO SOUTH CENTRAL OKLAHOMA.
TORNADOES FORMED EARLIER THIS AFTERNOON WITH THESE STORMS AS WELL AS VERY
LARGE HAIL.  THE DRYLINE IS CURRENTLY STATIONARY...AND CONDITIONS REMAIN
FAVORABLE FOR STORMS TO CONTINUE TO DEVELOP ALONG THE DRYLINE THIS
AFTERNOON AND EVENING.  LARGE HAIL...STRONG WINDS AND ISOLATED TORNADOES
WILL BE POSSIBLE.  A TORNADO WATCH CONTINUES IN EFFECT FOR SOUTHERN OKLAHOMA
