   Areas affected...Central/Western OK

   Concerning...Severe Thunderstorm Watch 367...368...

   Valid 110021Z - 110145Z

   The severe weather threat for Severe Thunderstorm Watch 367, 368
   continues.

   SUMMARY...Severe threat will continue across central and western OK
   through the evening as thunderstorms develop along the cold front.

   DISCUSSION...Recent surface analysis placed the cold front from
   about 50 miles northwest of CSM to about 15 miles northwest of BVO.
   Much of the activity in northeast/north-central OK has occurred
   ahead of the cold front thus far, but the most recent storm
   development south of END and near JWG is occurring along the wind
   shift associated with the cold front. Remnant outflow boundary also
   exists from just southwest of CSM to just south of JWG. 

   The air mass south of the front across central and western OK is
   strongly unstable and moderately sheared and severe thunderstorms
   are still expected to develop southwestward along the front over the
   next few hours. Some hail is possible with initial updrafts, but
   quick linear development is anticipated as the outflow surges
   southward, resulting in strong wind gusts as the primary threat. Low
   probability tornado potential will still exist for the next few
   hours, but weak low-level vertical shear show limit the overall
   threat.
