...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected across the U.S. today through
tonight.

...Synopsis...
Cool and stable conditions will persist across much of the country
for today and will limit thunderstorm potential. Modest moisture is
expected late tonight into eastern TX as a surface high gradually
shifts east and supports onshore trajectories out of the
northwestern Gulf. A cold front pushing south across the Plains
overnight will begin to impinge on this returning moisture across
the Texarkana region between 09-12 UTC Tuesday morning. While
shallow convective showers appear probable, consensus among forecast
guidance is that warm mid-level temperatures will limit thunderstorm
potential until more substantial cooling aloft occurs (which will
most likely occur after 12 UTC Tuesday).
