Day 1 Severe Weather Outlook

Valid 220100Z – 221200Z


A couple of thunderstorms could develop near the southern California
coast late tonight.

…Southern CA…

Strong mid-level height falls will spread across southern CA ahead
of a pronounced upper trough off the CA Coast. Exit region of a
90kt 500mb jet will translate into southern CA around daybreak
which is expected to enhance the possibility for offshore convection
to move inland toward the end of the period. 00z sounding at NKX
remains dry and stable this evening and this supports the primary
threat of convection after 09z. Even so, the greatest risk for
thunderstorms should be later in the day2 period as the trough moves
