....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS COASTAL
SOUTHERN CALIFORNIA...

....SUMMARY...
Locally damaging wind gusts and/or a brief tornado are possible over
parts of coastal southern California this evening.

....01z Update...

Upper low is sagging south off the central CA Coast early this
evening. As a result, the primary warm conveyor will persist across
southern CA with favorable onshore flow for maintaining lower 50s
surface dew points near the coast. While buoyancy remains limited,
wind profiles continue to favor potential storm rotation, and there
remains some concern for one or two low-topped supercells to evolve
offshore, then move inland, primarily over the LA Basin. 00z
sounding from NKX exhibited negligible instability, but this is
notably southeast of the jet, though strongly sheared. Greater risk
for robust updrafts will be north of the jet were higher buoyancy
will continue to be noted.
