Snowstorm and Rain Showers Fall on Northern California, Days After Spring Heat Wave

Just days after parts of the valley reached 90 degrees, and less than a day removed from the earliest fire weather warning ever issued in spring, rain and snow fell Monday across Northern California amid a 30-degree cooldown expected to last most of this week.

Chain controls were in place on several mountain highways Monday morning, Caltrans said, as the National Weather Service predicts about a foot of snow could fall at the pass level in the central Sierra Nevada range by the end of the day. Snow will fall as low as about 4,000 feet.
