...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected across the contiguous United
States through tonight.

...West TX/OK...
A deepening upper low over southeast AZ will track slowly eastward
today into the southern High Plains.  Widespread low-level warm
advection will lead to showers and isolated thunderstorms over west
TX and much of OK, with much of this precipitation atop sub-freezing
surface temperatures.

...Southeast LA to the FL Panhandle...
Tropical Storm Zeta is moving offshore and away from the Yucatan
Peninsula today.  An increasingly moist and marginally unstable air
mass will spread inland tonight across the central Gulf Coast
region, with the potential for isolated thunderstorms after
midnight.  The outer bands of the system are forecast to remain
primarily offshore tonight, with an increasing severe risk in parts
of this area tomorrow.
