   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   A couple of weak thunderstorms are possible near the Rio Grande
   River and higher terrain of southwest Texas, but the risk of
   thunderstorms appears negligible elsewhere Thursday through Thursday
   night.

   ...Synopsis...

   Northwesterly mid/upper flow will persist across much of the U.S. on
   Thursday. A somewhat flat upper ridge will migrate east/southeast
   from the southern Rockies to the lower MS Valley as a shortwave
   trough develops over the southern High Plains late in the period.
   Surface high pressure over the southeastern states and developing
   lee troughing over the High Plains will allow for southerly
   low-level flow transporting Gulf moisture north and west across
   parts of TX. As the upper shortwave trough approaches the Rio
   Grande, weak destabilization amid this warm advection regime should
   support a few thunderstorms across southwest TX, though severe
   potential will remain low. Dry and stable conditions will envelop
   much of the rest of the CONUS, negating thunderstorm potential.
