    ...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.
