Interstate 80 was closed and chains were required on Highway 50 on Monday as a cold system brought blowing snow to lower elevations.
Caltrans took to Twitter at 4:45 a.m. to report that I-80 was closed eastbound at Applegate and westbound at Stateline due to zero visibility over Donner Summit. The highway reopened midafternoon to all vehicles except single-axle trucks and those pulling double trailers.
On Highway 50, chains were required from 4 miles east of Placerville to Meyers.
The National Weather Service forecast called for overnight snow showers in the Sierra, possibly turning to rain Tuesday morning, with skies clearing Tuesday night through Thursday.
