...STRONG THUNDERSTORMS DEVELOPING OVER THE OKLAHOMA CITY METRO AREA...

AT 705 PM RADAR INDICATED DEVELOPING THUNDERSTORMS OVER CLEVELAND COUNTY
IN THE VICINITY OF NORTH NORMAN AND MOORE. THESE STORMS HAVE DEVELOPED
RAPIDLY AND WERE MOVING EAST-NORTHEAST AT 20 MPH. HAIL AND STRONG
WINDS ARE LIKELY.  BOATERS ON LAKE THUNDERBIRD AND LAKE DRAPER SHOULD
REMAIN ALERT TO THE APPROACH OF THESE THUNDERSTORMS.

A TORNADO WATCH REMAINS IN EFFECT UNTIL MIDNIGHT FOR THE METRO AREA.
AND THIS HAS SERVED TO LIMIT THE AMOUNT OF CONVERGENCE ALONG THE
FRONT AND OUTFLOW BOUNDARY. AS AFTERNOON HEATING CONTINUES AND
TEMPERATURES RISE WELL INTO THE 80S THUNDERSTORMS ARE EXPECTED TO
DEVELOP IN THE MODERATE RISK AREA AND INTENSIFY RAPIDLY TO SEVERE
LEVELS. THE THUNDERSTORMS WILL THEN MOVE NORTHEAST.

THE PRIMARY THREAT FROM THUNDERSTORMS THIS AFTERNOON WILL BE
LARGE HAIL. THE AMOUNT OF INSTABILITY PRESENT THIS AFTERNOON
SUGGESTS THAT SOME THUNDERSTORMS MAY PRODUCE BASEBALL-SIZED HAIL.
ISOLATED TORNADOES ARE ALSO POSSIBLE.

LAW ENFORCEMENT AND SPOTTER ORGANIZATIONS IN THE MODERATE RISK
ASREA SHOULD BE PREPARED FOR ACTIVATION AT ANY TIME THIS AFTERNOON.
