A few lightning flashes may occur near coastal northern
California/southern Oregon.

As an upper short-wave trough continues to vacate the eastern U.S.
and the low near the West Coast weakens, flow aloft will become more
quasi-zonal with time.  This will contribute to persistence of a
low-level continental polar airmass across the country.  Given the
overall lack of instability, thunder risk will remain low overall. 
The greatest potential for a few lightning flashes will persist over
the southern Oregon/northern California coasts, near the weakening
upper low.  Elsewhere, potential for lightning should remain minimal
at best across the Southeast/southern Plains, and near zero
elsewhere east of the Rockies.
