• KCRA reported morning showers and lightning moving through parts of the Sacramento Valley, with the most active storms shifting to the Sierra and Foothills by afternoon.
• Thunderstorm chances persist into Wednesday and Thursday, with the greatest coverage over higher terrain and only isolated strikes possible in lower elevations.
