...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe thunderstorms are not expected through tonight.

...Discussion...

Primary areas of thunderstorm development tonight will be the
southern Rockies vicinity in association with ascent and steep lapse
rates downstream from a shortwave trough, as well as farther east
across the southern Plains region. Storms across the southern Plains
will likely develop later tonight as a southerly low-level jet
strengthens, augmenting isentropic ascent and theta-e advection in
vicinity of a southwest-northeast oriented baroclinic zone. Activity
will remain elevated above a stable surface layer. While some hail
cannot be ruled out with storms over western TX where steep mid
level lapse rates and somewhat greater instability will reside,
activity is generally expected to remain below the severe threshold.
