   Areas affected...northern Oklahoma

   Concerning...Severe potential...Watch unlikely 

   Valid 300948Z - 301215Z

   Probability of Watch Issuance...5 percent

   SUMMARY...A cluster of storms over north-central Oklahoma will
   likely persist for a few hours, and may turn left a bit into
   northeast Oklahoma. Isolated severe gusts are possible.

   DISCUSSION...Surging outflow out of KS has maintained intensity with
   new cluster development from northwest into north-central OK.
   Mesonet observations indicate 3 to 4 mb 2-hr rises with the outflow.
   Meanwhile, similar fall magnitudes have been measured in the wake of
   the earlier storms over northeast OK.

   VAD winds over central OK show around 30 kt west/southwest flow just
   off the surface, which will serve to recover elevated instability
   ahead of the cluster. Given the aforementioned pressure falls over
   northeast OK, more of an eastward propagation may eventually be
   preferred with a few strong gusts possible into northeast OK.
