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

....SUMMARY...
Severe thunderstorms are not expected through early Tuesday.

....Synopsis...
West-southwesterly flow aloft will persist through tonight from the
Southwest into the OH Valley, between a deep low west of Hudson Bay
and a subtropical ridge over the Gulf of Mexico.  Subtle
perturbations within this flow regime, and a gradual increase in
low-level warm/moist advection will support the potential for
elevated thunderstorms from the Mid-South into the TN Valley by
tonight.  Midlevel lapse rates and buoyancy should remain too weak
to support severe storms.  Otherwise, isolated lightning flashes may
occur near El Paso where weak buoyancy will correspond with the edge
of a persist low-midlevel moisture plume.  Isolated thunderstorms
will also be possible across the Sacramento Valley and northern CA
coast in association with cool midlevel temperatures/steep lapse
rates as a midlevel low moves inland and evolves into more of an
open wave.
