valid. See prior discussion below.

...Grams.. 11/23/2023

..PREV DISCUSSION... /ISSUED 1010 AM CST Thu Nov 23 2023/

....Synopsis...
An upper-level low approaching deep South TX will continue lifting
east/northeast today towards the southern Appalachians/Southeast
while transitioning into an open wave. Occasional lightning flashes
were noted earlier across the western Gulf of Mexico, however the
lack of notable buoyancy across the Southeast and Gulf Coast and
general weakening of large-scale ascent with time precludes any
appreciable risk for thunderstorms through tonight.

Farther west, an upper trough will dig southeast and close off over
NV/UT. Increasing ascent/mid-level cooling could result in an
isolated lightning flash in the vicinity of the evolving upper low,
but the overall thunder potential is very low.
