..no thunderstorm areas forecast... 

thunder probabilities will remain low across the country Saturday, 
although a few lightning strikes may occur across deep south Texas 

..deep south Texas... 

Weak mid-level short-wave trough within southern stream is forecast 
to eject across northern Mexico into deep south Texas by the end of the 
period. In response to this feature, weak pressure falls will 
develop over the northwest Gulf basin and low-level warm advection 
should increase inland over deep south Texas. Forecast soundings 
suggest weak buoyancy will evolve after midnight and shallow 
elevated convection may ultimately develop within this warm 
advection regime. If instability ultimately is greater than 
currently forecast more robust/deeper updrafts could attain heights 
sufficient for lightning. At this time thunder probabilities appear 
less than 10%.
