..PREV DISCUSSION... /ISSUED 1029 AM CST Sun Jan 21 2024/

....Discussion...
Overall thunderstorm potential will be fairly limited/confined, with
severe thunderstorms not expected across the CONUS. Expansive
surface high pressure will prevail across the eastern half of the
CONUS, along with an accompanying cold continental airmass.
Low-level warm advection will expand across the southern Plains into
tonight, with a northward transport of higher theta-e air. This will
support elevated destabilization, and the development of showers and
thunderstorms across parts of central and eastern Texas tonight.

In the West, multiple low-amplitude disturbances will spread inland
and across the West and Southwest deserts through tonight. Pacific
moisture and weak instability will support a few thunderstorms,
across southern Arizona vicinity today, and portions of coastal
California tonight.
