   Day 1 Convective Outlook

   Valid 290100Z - 291200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   The risk of thunderstorms appears negligible across much of the U.S.
   through tonight.

   ...01Z Update...
   Some lightning was noted earlier today with convection beneath the
   cold core of a weakening mid-level low, which is now a couple
   hundred miles west-southwest of the northern California coast.  The
   remnant mid-level circulation may shift into coastal areas near
   Eureka by late tonight, but the associated weakening, occluded
   surface low and front are forecast to remain offshore of the
   California coast.  Stronger mid-level forcing for ascent and
   cooling, within the exit region of a digging jet streak (to the west
   of the mid-level trough axis), may approach coastal areas south of
   San Francisco Bay overnight, possibly supporting a developing band
   of frontal convection with some lightning.
