...Discussion...
A prominent longwave trough will remain entrenched from the Rockies
to the western Atlantic, with a general prevalence of cold/dry
continental trajectories and surface high pressure over the eastern

increase in low-level moisture toward coastal Texas tonight.
However, instability is expected to remain too limited to support
thunderstorms through tonight.
