..no severe thunderstorm areas forecast... 

a few weak thunderstorms may be noted early in the period across 
portions of California. 


Substantial mid-level flow will dig southeast across central California 
toward the lower Colorado River valley by 18/00z before progressing into 
northern Mexico during the overnight hours. Seasonally cool 500mb 
temperatures north of this jet will allow steep mid-level lapse 
rates to spread across central California toward extreme West Texas by the end 
of the period. While weak convection may be noted along this 
corridor in advance of the speed Max, low precipitable water air mass should limit 
lightning potential across most of this region. However, a few 
strikes may be noted early across portions of California but this too will 
be quite sparse.
