Chance of Thunderstorms Saturday and a Cold Storm Next Week

Some dramatic shifts in weather forecast for the next week will make summer seem long gone.

It begins tonight with a 20 percent chance of thunderstorms, according to the National Weather Service. “Unsettled” weather will continue into the weekend with a slight chance of rain through Sunday as moisture from Hurricane Hillary spreads into the region.

The Weather Service on Friday issued a hazardous weather statement for most of Southern California, including Orange County Coastal areas.

"An upper level low off the coast will combine with some subtropical moisture today to bring isolated to scattered high based thunderstorms," the statement reads. "These thunderstorms will be capable of producing gusty winds, dry lightening and hail."

In San Juan Capistrano, highs will be in the mid to upper 70s this weekend. There will be a 20 percent chance of showers during the Saturday morning.

By mid next week, National Weather Service meteorologists expect an unseasonable cool Pacific storm to blow into the area from Northern California, bringing rain and temperatures 20 degrees below normal.
