.PREV DISCUSSION... /ISSUED 1010 AM CST Wed Dec 31 2025/

...Synopsis and Discussion...
With upper ridging remaining prominent over the western CONUS and
upper troughing centered across the eastern states, thunderstorm
potential should remain minimal though tonight for a large majority
of the CONUS. One exception will be across parts of southern CA late
tonight into early Thursday morning, as an upper trough/low over the
eastern Pacific gradually approaches the CA Coast by the end of the
period. While low-level moisture and related instability are both
expected to remain limited, increasing large-scale ascent and
gradually cooling mid-level temperatures preceding the upper
trough/low may still support isolated convection capable of
producing occasional lightning flashes, mainly after 01/06Z. Both
MUCAPE and deep-layer shear appear too weak to support a meaningful
threat for organized severe thunderstorms through the end of the
period (12Z Thursday morning).
