Valid 141200z - 151200z
..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.
