KEY POINTS
• Scattered thunderstorms again Saturday, mainly in the mountains, but a few storms may drift into the valley and coastal areas.
• Much lower chances for thunderstorms on Sunday.
• Tranquil weather is generally expected for Southern California next week.

Rain was scattered across the Southland Friday ranging from a few hundredths in the Inland Empire Metro area and the surrounding mountains to nearly 2-inches in the higher elevations of San Diego County.

The California Highway Patrol reported flash flooding made roads impassable in the Yucca Valley area, especially at low water crossings on Highway 62.

Friday’s storms extended beyond the Inland Empire. The National Weather Service noted it is quite rare for such strong thunderstorms that are organized to impact greater San Diego.

Cooler weather is accompanying the stormy outbreak with temperatures dropping 5-degrees below normal Sunday.

Another low pressure trough is predicted to set-up along the West Coast reinforcing the cooler air and creating quite windy conditions across the mountains and deserts Tuesday.
