....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorm potential appears low on Saturday.

....Synopsis...
A deep mid/upper-level trough will persist over the central/eastern
CONUS on Saturday. An upper-level ridge will extend from the
Southwest into the Pacific Northwest, while a weak mid/upper-level
trough will begin to approach the California coast. In the wake of a
cold front, an expansive surface ridge will maintain generally
dry/stable conditions across the CONUS, with limited thunderstorm
potential.

Cold temperatures aloft will continue to support lake-effect snow
bands across the Great Lakes, and isolated lightning flashes cannot
be ruled out with the strongest bands. Some low-level moisture
return may commence into Deep South TX, but inland deep convection
appears unlikely in the absence of stronger buoyancy and large-scale
ascent. Farther west, the 00Z NAM is an outlier in developing modest
elevated buoyancy across southern CA in advance of the approaching
upper trough, while other guidance currently suggests little
appreciable thunderstorm potential in this area.
