Temperatures are running 10 degrees below normal for late May across California.
Scattered showers and isolated thunderstorms are expected, particularly in the Sierra and foothills.
Snow is possible above 6000 feet, with slushy conditions likely in mountain passes.
Caltrans has temporarily closed Sonora Pass (Highway 108), Ebbetts Pass (Highway 4), and Monitor Pass (Highway 89) due to the anticipated weather system.
The unsettled weather pattern is expected to last through Thursday, with temperatures warming into the weekend.
Why this matters: This unusual weather pattern can impact travel, outdoor activities, and local communities. Mountain pass closures can disrupt transportation routes, and the potential for thunderstorms and snow requires extra caution.
The current weather system is characterized by a disturbance spinning around Northern California, leading to widely scattered showers and potential thunderstorms. The Sierra Nevada is particularly susceptible to snow at higher elevations. Caltrans has proactively closed several mountain passes, including Sonora Pass, Ebbetts Pass and Monitor Pass, to ensure public safety. These closures are temporary, and the passes will be inspected and reopened once the weather system passes and conditions are deemed safe. The system is expected to move eastward by the end of the week, leading to a gradual warming trend. While the valley may experience a stray shower, the foothills and Sierra are more likely to see widespread activity. Travelers should check conditions before departure.
