There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS MUCH OF COASTAL CALIFORNIA AND PORTIONS OF THE CENTRAL VALLEY SUMMARY An isolated risk for severe/damaging gusts and perhaps a brief tornado will exist today into tonight along much of the California Coast and portions of the Central Valley. Central/Northern California Water vapor imagery shows the shortwave trough already moving inland. In the wake of this activity, visible satellite shows potential for cloud cover to reduce within the Central Valley from west to east. Some forecast soundings show destabilization is possible by late afternoon. Given the southeast flow within the Valley and strong flow aloft, a conditional threat for a marginal supercell/brief tornado could develop. Greater confidence exists with activity later in the evening into Thursday morning associated with a secondary, stronger shortwave trough. Another narrow band of convection is expected ahead of this shortwave and will impact parts of the central/northern California Coast and eventually parts of the Central Valley as well. Isolated damaging winds and a brief tornado would be possible with this activity. Southern California A spatially limited threat for wind damage and a brief tornado will exist for another few hours this afternoon. A low-topped band of convection recently moved through much of the LA Basin and will generally continue eastward. There may be a narrow sliver of dewpoints near 60 F just east of this activity. Dewpoints closer to San Diego are only in the upper 50s F, however. Strong wind shear at low levels will maintain this marginal risk, though decreasing buoyancy southward and inland should lead to a downward trend in intensity.
