   Day 3 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   0220 AM CST Wed Dec 07 2022

   Valid 091200Z - 101200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe weather is not expected across the U.S. on Friday.

   ...Discussion..
   Some amplification of the flow field aloft is expected Friday, as
   long-wave troughing continues to evolve over the West. 
   Specifically, an initial trough that is progged to move onshore
   Thursday, is expected to shift northeastward across the interior
   West, while a second wave digs south-southeastward out of the Gulf
   of Alaska toward the West Coast.  Meanwhile, as the
   longer-wavelength troughing evolves, downstream over the Gulf of
   Mexico will be maintained across the Southeast/Mid-South in
   response.

   At the surface, the west-to-east baroclinic zone lying from the
   southern Plains to the southern Appalachians will shift southward
   into the Southeast with time, but should move little over the
   southern Plains as a weak frontal wave evolves over Texas.

   Showers and potentially a few lightning flashes will occur during
   initial stages of the period in the vicinity of the front over
   Tennessee and into the southern Appalachians.

   Overnight, elevated convection may evolve over the Oklahoma/north
   Texas vicinity, as low-level warm advection increases somewhat ahead
   of the evolving western trough.

   Finally, convection -- with a few embedded lightning flashes -- may
   affect th southern Oregon/northern California Coasts toward the end
   of the period, as the digging eastern Pacific short-wave trough
   approaches.

   In all areas, severe weather is not expected.
