A storm system is bringing more rain and snow to California on Sunday, with scattered showers and thunderstorms expected in the Valley and Foothills, and snow levels dropping below 4,000 feet in the Sierra Nevada mountains. Chain controls are in place on several major highways, and the wet weather is expected to continue through the early part of the week before drier conditions return.

Why it matters

The ongoing rain and snow is causing disruptions to travel and outdoor activities across the region, and the potential for heavy downpours and small hail could lead to localized flooding and other hazardous conditions. The Sierra snowfall is also an important factor for the state's water supply.

The details

As of Sunday morning, snow levels have dropped below 4,000 feet, with snow currently falling in Pollock Pines. Chain controls are in place on portions of Interstates 80 and 50, as well as Highway 88. Snow showers are expected to continue throughout the day, with snow levels rising to around 4,500 feet. In the Valley and Foothills, scattered rain showers and isolated thunderstorms are forecast, with the potential for heavy downpours, frequent lightning, and small hail, though the storms are not expected to reach severe criteria. Ponding on roadways is possible, especially where drains are clogged with debris.

• As of 5:00 am Sunday, it is currently snowing in Pollock Pines.
• Chain controls are in place for portions of 80, 50, and 88.
• Snow showers will continue on and off throughout the day.
• Scattered rain showers and isolated thunderstorms are expected in the Valley and Foothills again on Sunday.
• Rain showers will wrap up overnight with a few lingering sprinkles possible in the Foothills on Monday.

What’s next

Dry conditions are expected on Tuesday and Wednesday, but another low pressure system may bring more wet weather to the region on Sunday afternoon into Monday.
