Valid 211200Z - 221200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected on Tuesday.

....Southern California...
An upper trough is expected to spread east-southeastward over
California toward the Great Basin and Southwest deserts on Tuesday,
with a substantially strengthening low-latitude polar jet over the
International border vicinity. As mid-level lapse rates steepen,
low-level moisture and overall buoyancy will be sufficient for
isolated thunderstorms, particularly for coastal areas. While
organized severe thunderstorms are not currently expected, some
small hail and/or thunderstorm-related gusty winds are plausible.

....Central Plains/Midwest...
A few/very isolated elevated thunderstorms could occur early Tuesday
and/or persist eastward into/across Missouri during the day,
attributable to warm/moist advection focused at the terminus of the
low-level jet. A secondary round of storms could develop under a
somewhat similar regime Tuesday night. Severe thunderstorms
currently appear unlikely, owing to weak elevated buoyancy.
