..no thunderstorm areas forecast... 


... 
thunderstorms are not expected across the contiguous states on 
Thursday and Thursday night. 


... 
A large-scale upper pattern featuring a western ridge and eastern 
trough will remain through Thursday, with a low-level reinforcement 
of cool air to spread across the southern U.S. In the wake of a weak 
surface frontal advance into the Gulf of Mexico. 


Given the upper pattern, and reinforcement of cool/stable 
Continental air east of The Rockies, little appreciable risk for 
thunder is evident. 


A very low risk for a lightning strike or two may evolve during the 
second half of the period over the far southern New Mexico/upper Rio 
Grande Valley area of far western Texas, within a zone of weak qg 
forcing. Weak instability however suggests that widespread 
lightning is unlikely.
