....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.
