   Day 3 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1219 AM CST Sat Dec 15 2018

   Valid 171200Z - 181200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   A few weak thunderstorms may be noted early in the period across
   portions of California.

   ...CA...

   Substantial mid-level flow will dig southeast across central CA
   toward the lower CO River Valley by 18/00z before progressing into
   northern Mexico during the overnight hours. Seasonally cool 500mb
   temperatures north of this jet will allow steep mid-level lapse
   rates to spread across central CA toward extreme west TX by the end
   of the period. While weak convection may be noted along this
   corridor in advance of the speed max, low PW air mass should limit
   lightning potential across most of this region. However, a few
   strikes may be noted early across portions of CA but this too will
   be quite sparse.
