New post on http://twitter.com/CaltransDist10 : Bitter cold and snowfall hit parts of the Sierra Nevada this past weekend, and it looks like more to come! Our friends NWSSacramento warn of another hard freeze tonight throughout the San Joaquin Valley, with snow likely on Carson, Ebbetts, Sonora and Tioga Pass this week. http://pic.twitter.com/Weum7QbU2D
