(KRON) — A major winter storm forecast to hit Northern California this weekend could potentially dump almost 10 feet of snow in the Sierra. According to the UC Berkeley Central Sierra Snow Lab, a significant storm expected from Thursday through Sunday could bring 6 to 9 feet of snow.

“We have been monitoring the chance for a significant storm Thurs-Sun this week,” the snow lab tweeted. “There is still time for the forecast to change but we’re currently expecting 6-9 feet of snow.”

Most of the snow is expected to fall Friday into Saturday morning, the snow lab said.

KRON4 Meteorologist John Shrable said we could be in for “one of our biggest snow makers of the season.”

“We’re going to be talking about multiple inches,” said Shrable. “In fact, getting close to 100 inches of snowfall at the very crest of the Sierra.”

“All that snow is going to result in likely a lot of closures, especially as we work into Friday and Saturday,” Shrable continued. With snow even expected in some lower elevations, routes like I-80 and Highway 50 could be impacted, Shrable added.

After a warm weekend and a relatively dry start to the week, the approaching weather system is expected to bring increased chances for rain to the Bay Area later this week, according to the National Weather Service.
