   ...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.
