SPC AC 150619
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...
A few weak thunderstorms may be noted early in the period across
portions of California.
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.
