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 ALONG MUCH OF THE CALIFORNIA COAST AND INTO THE CENTRAL AND NORTHERN VALLEYS SUMMARY The risk for isolated severe thunderstorms will persist this evening and into tonight across much of the California Coast and portions of the Central and Northern Valleys. Coastal CA into the Central and Northern Valleys Scattered showers and thunderstorms persist this evening from the Sacramento Valley toward the central coastline, with another area over southern CA. Areas of heating have led to a few stronger cells around the Sacramento area, with indications of marginal hail. To the west, another frontal band of convection will continue to approach much of the central coastal counties. The 00Z OAK sounding shows steep lapse rates and strong shear profiles, which may favor both damaging gusts or embedded areas of rotation as leading cells and/or the frontal band approach later this evening. As such, will maintain the Marginal Risk. For more information, see mesoscale discussion 2272.
