   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms are not currently forecast across the
   contiguous United States on Wednesday.

   ...Synopsis...
   A longwave mid-level trough will be over eastern North America while
   a ridge is located over the Interior West.  A disturbance moving
   southeastward into the base of the larger-scale trough will aid in
   showers/thunderstorms developing across central into eastern TX and
   LA on Wednesday and Wednesday night.  A frontal zone will push
   southward through north-central TX and into the Hill Country during
   the day.  Weak buoyancy with parcels rooted near 700 mb will result
   in episodic clusters of showers/thunderstorms continuing from
   Tuesday night into Wednesday morning and persisting through the
   period as this activity moves southeast to the coast.  

   Farther west, a vigorous mid-level trough over the eastern Pacific
   will approach northern CA/OR with isolated thunderstorms possible
   near the coastal range.
