Travelers driving through parts of the Sierra Nevada on Sunday were treated to some unexpected June weather: Snow. Chain controls were in effect on Sunday and overnight in Donner Pass on Interstate 80, but have since been lifted. A tweet from the National Weather Service in Sacramento said 5 inches of snow fell in Kingvale, in the Northern Sierra. Parts of Highway 50 and Lake Tahoe also received a dusting of snow. “That’s the one thing about the Sierras – it’s unpredictable,” said Caltrans spokeswoman Deanna Shoopman. “The weather can just change at the drop of a hat.”
