...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 today and tonight.
...DISCUSSION...
Northwest mid-level flow will be in place across most of the
continental United States today. At the surface, a cold front will
advance southeastward into the Ohio Valley as weak low-level
moisture return takes place across parts of Texas. Some instability
should develop in the Rio Grande Valley of west and southwest Texas
this afternoon. Isolated thunderstorms will be possible late this
afternoon in the mountains of west Texas. However, this activity
should remain sub-severe. Elsewhere across the continental United
States, thunderstorms are not expected today or tonight.
