The core of a small storm system is spinning a few hundred miles to the southwest of San Diego (you can spot it on the satellite loop below). This storm will move this way Monday and bring a chance for rain throughout southern California.
Although a stray shower could pop up in the morning, the best chance for showers and isolated thunderstorms will start in the late afternoon and then persist into the night. The rain chance will be gone by 10 AM Tuesday. Rain totals will generally be less than a quarter inch except for areas that see a thunderstorm, where totals could reach around a half inch. I've posted computer forecast rain totals below.
The weather pattern will remain active into the weekend. A few showers could pop up Friday or Saturday (20%), but a better chance should arrive by Sunday (30%). I'll keep an eye on it and bring more updates as those other storms move closer to the area. One thing is for certain: a cooler weather pattern is settling into the region for the next couple weeks.
