   The severe weather threat for Tornado Watch 508 continues.

   SUMMARY...Severe threat will spread across the remainder of ww508
   over the next several hours.

   DISCUSSION...Two primary bands of convection have developed ahead of
   a pronounced cold front that currently drapes from east of Kansas
   City-southeast KS-northern Oklahoma. Frontal convection has
   gradually increased in response to large-scale forcing but this
   activity is evolving within a veered low-level flow regime, thus the
   storm mode should remain primarily linear as the front surges
   southeast. However, ahead of the frontal convection, earlier
   activity that initiated near the KS/OK/MO border has spread
   northeast and elongated into a zone of scattered supercells and
   short line segments. Several stronger circulations have been noted
   within this corridor which is advancing steadily east ahead of the
   strong short-wave trough.  As boundary-layer moisture increases
   across the Ozark Plateau, buoyancy should increase such that
   near-surface based supercell threat will continue.
