More cold unstable weather

A cold upper low will drop swd along ca coast to a position vicinity lax by 12z wed. steep lapse rates and ascent s of e of low track will lead to considerable low topped convection including at least isolated thunderstorms primarily over and west of coastal range
along the track of the upper low as it moves down the coast. given the cold air aloft ... small hail will be likely associated with
stronger convection during the afternoon and evening. the limited instability and generally weak shear ... precludes introducing a
severe threat attm.

did spread the thunderstorm threat ewd across the mohave deserts region of srn ca where models suggest stronger ascent coupled with steep lapse rates will develop during the afternoon.
