   Valid 301200Z - 311200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe weather is not expected across the U.S. on Saturday.

   ...Discussion...
   A mid-level low/short-wave trough initially expected to be centered
   over the central/southern High Plains region, is forecast to move
   steadily east-northeastward through the period.  The feature should
   reach the middle Mississippi Valley vicinity during the evening, and
   then continue into/across the Midwest/Ohio Valley region overnight.

   At the surface, an accompanying low is forecast to move across
   Oklahoma/Kansas and into Missouri by evening, and then reach the
   southern Illinois/southern Indiana area by Sunday morning.  A
   trailing cold front will move southeastward across the southern
   Plains, and later across the Lower Mississippi Valley area and into
   the northwestern Gulf of Mexico.

   Showers will accompany the advance of the surface system,
   particularly during the second half of the period across the
   Tennessee Valley region and southward across the central Gulf Coast
   states.  A few lightning flashes are expected nearer the pool of
   colder air/steep lapse rates aloft associated with the upper system
   as it shifts east-northeastward with time, within a zone from the
   Kansas/Oklahoma vicinity east-northeastward into Illinois.
