Valid 301630Z - 311200Z

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

....SUMMARY...
Severe thunderstorms are not expected through tonight.

....Synopsis...
A midlevel low will move east-southeastward from near the southern
CA coast to northwest Mexico by Tuesday morning, with the potential
for some low-topped convection and isolated lightning flashes close
to the southern CA coast.  Farther east, midlevel ridging will
persist over FL, with low-amplitude speed maxima translating
east-northeastward from the southern Plains to the Atlantic coast.
Isolated thunderstorms will still be possible along a stalled front
from southeast LA to southern GA, but weak forcing for ascent
suggests that storm coverage will be isolated at best.

The most pronounced thunderstorm threat today will be with the
elevated convection over central/eastern OK into north TX.  Regional
12z soundings revealed 100-300 J/kg MUCAPE rooted in the 850-700 mb
layer, which will support a continued threat for elevated
thunderstorms through the day.  The majority of this convection will
occur atop a sub-freezing boundary layer, with primarily thunder
sleet in OK and a mix of thunder freezing rain/sleet farther south
in TX.
