Severe Storm Risk - Orange, CA

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 PORTIONS OF COASTAL SOUTHERN CALIFORNIA SUMMARY Locally damaging winds, and perhaps a brief weak tornado, could occur along a portion of coastal southern California. Southern CA Early-morning satellite imagery depicts a well-defined shortwave trough off the southern CA coast (about 220 miles west-southwest of Lompoc CA). This shortwave is forecast to continue northeastward, reaching the coast early this morning before then progressing through central CA and into NV, deamplifying notably as it does. A jetlet, characterized by around 50 kt at 500 mb, will accompany this wave, spreading across central and southern CA in tandem with the wave's northeastward progress. The leading edge of this stronger flow aloft is being sampled by the VTX VAD. This overall progression is contributing to broad ascent across much of central/southern CA, evidenced by the widespread precipitation across the region. Some stronger ascent and associated deeper convection is occurring across San Luis Obispo and Santa Barbara counties. Southern extent of this stronger ascent will likely contribute to some deeper convection from the Channel Islands to the southern CA Coast. Mid-level temperatures will be cooling across this region as well, which could result in modest buoyancy within a relatively shallow layer. This could result in enough buoyancy for a few lightning flashes, although lapse rates are generally expected to remain poor. Wind profiles support the potential for a strong, convectively aided gust, and perhaps even a brief tornado, if updraft depth and persistence is sufficient. However, given the scarcity of buoyancy, the majority of convection will remain sub severe.
