   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms are not expected through tonight.

   ...Synopsis...
   Around the northwest periphery of the persistent mid-upper ridge
   over the Gulf of Mexico, and in advance of a shortwave trough
   approaching the Pacific Northwest coast late, a midlevel trough will
   eject east-northeastward from the lower CO River Valley to the
   southern/central High Plains.  A cold near-surface air mass will
   tend to mute lee cyclogenesis potential downstream from the ejecting
   trough, such that a surface baroclinic zone will move little from
   north TX to the TN Valley through tonight.  Isolated thunderstorms
   will be possible today along the front from the Mid-South into the
   TN Valley, and the potential for thunderstorms (mainly elevated)
   will increase some this evening into tonight from west TX into OK in
   a strengthening warm advection regime associated with a lead
   shortwave trough.  Severe storms are not expected as a result of
   poor midlevel lapse rates and weak buoyancy.
