An upper-level low-pressure system developing off of the Central Coast is bringing thunderstorms and rain showers to the region through today, according to John Lindsey, a local forecaster and media representative with Pacific Gas and Electric Co.
That system is expected to move south and parallel to the coastline through today, and then southeast along Southern California through Wednesday.
Brief, but heavy, rain, as well as hail, gusty winds and lightning can accompany thunderstorms, Lindsey said.
Scattered light rain showers will linger through Monday night, he said.

The season has totaled just under a half inch of rain since starting on July 1, he added.
Mostly fair weather will develop by Tuesday afternoon and will continue through Thursday, Lindsey said.
The National Weather Service has issued a Marine Weather Statement suggesting caution in waters off the coast from Piedras Blancas in northern San Luis Obispo County to Point Mugu in Ventura County.
The Weather Service warns of winds gusting as strong as 35 knots, as well as possible hail and dangerous cloud-to-ocean lightning with heavy rain.
Mariners should be prepared for rapidly changing conditions, with thunderstorms moving 35 to 40 mph to the northeast, according to the Weather Service.
