   Areas affected...portions of central Oklahoma

   Concerning...Severe Thunderstorm Watch 686...

   Valid 200033Z - 200200Z

   The severe weather threat for Severe Thunderstorm Watch 686
   continues.

   SUMMARY...A few supercells are approaching the I-35 corridor in
   Oklahoma which may necessitate an watch expansion.

   DISCUSSION...A left-moving supercell has produced multiple reports
   of quarter to golf ball sized hail across southwest Oklahoma with
   one report of 2 inch hail in Roosevelt. The environment remains
   unstable ahead of this storm and should maintain its intensity to at
   least I-35. In addition, another supercell has developed in Canadian
   county and recently had a report of 1 inch hail. As both of these
   storms approach central Oklahoma, an areal expansion of watch 686
   will likely be needed.
