NWS: More significant wet pattern to return next week


From the National Weather Service:
Fairly light precipitation is anticipated to continue this weekend with periods of more widespread and heavier precipitation continuing through next week. Light precipitation with the weekend weather system will primarily affect the Sacramento Valley and surrounding mountains with a thunderstorm potential over north Sacramento Valley Sunday. Another storm system is likely to impact the region Monday through Tuesday with more systems impacting through at least the end of next week. Tuesday and Friday look to bring the brunt of the precipitation and wind, but precipitation amounts are more questionable late in the week.

Impacts
Slick roadways, increased traffic accidents, longer travel times next week
Mountain travel delays and chain controls
Windy conditions may bring localized power outages
Thunderstorms may bring locally heavy rainfall, small hail

Forecast Confidence
High - wet pattern (increased)
Medium - precipitation amounts

Timing and Strength
Weekend:
Light precipitation (except for a few thunderstorms Sunday), mainly north of Interstate 80. Snow levels 7000+ feet
Monday - Tuesday: Heavier, more widespread precipitation with scattered thunderstorms and breezy to windy conditions. Snow levels around 6000 feet.
Thursday - Friday: Additional storm systems with 4500-6000 foot snow levels with potentially windy conditions. (wettest system Friday)
