Unseasonal Storm System Brings Rain, Thunder Across California

Scattered showers and thunderstorms are expected across parts of California, including the Bay Area, through Tuesday evening.
The unusual weather pattern is bringing moisture from east to west, the opposite of the typical weather flow.
Some areas have already received significant rainfall, while other locations remain dry.
There is a chance of light rain in San Francisco Tuesday afternoon before conditions clear up in the evening.
The change in weather is due to a low pressure system moving through Southern California that will bring a return to more typical summer weather for most of the state by midweek.
