   Areas affected...Central Kansas and Oklahoma

   Concerning...Tornado Watch 276...

   Valid 290105Z - 290230Z

   The severe weather threat for Tornado Watch 276 continues.

   SUMMARY...Widely scattered severe storms, including supercells will
   continue to pose a risk for severe weather across and east of the
   I-135/35 corridors through 9-11 PM.

   DISCUSSION...The dryline has retreated some near/west of the
   Interstate 135/35 corridors of central Kansas into central Oklahoma.
   This boundary remains a focus for continuing thunderstorm initiation
   across Kansas, and low-level convergence coupled with cooling aloft
   seem to provide some potential for additional new development into
   Oklahoma.  Otherwise, strongly sheared 40-50 kt southwesterly deep
   layer ambient mean flow continues to support initial storm
   propagation off the dryline, across and east of the Interstate
   135/35 corridors, aided by inflow of strong boundary layer
   instability.  Storms likely will continue to pose a risk for severe
   hail, locally strong surface gusts and perhaps a tornado or two at
   least into late evening, before boundary layer instability begins to
   wane with the loss of daytime heating.
