Winter reared its ugly head around the country this weekend, blanketing upstate New York with nearly 3 feet of snow, coating Midwest highways with ice and resulting in at least one rare tornado making landfall in California.

On Saturday afternoon, several were injured when a tornado flipped cars and toppled utility poles and trees as it touched down near a shopping center in Scotts Valley — located about 70 miles south of San Francisco.

The City by the Bay also saw felled trees and damaged roofs, with officials still determining if the pummelling was also the result of a tornado, which would be the first to hit the Bay Area since 2005.

An alert went out to residents to take shelter as the storm rapidly moved in, the first such warning to ever be broadcast in the area, according to Roger Gass, a meteorologist in the weather service’s office in Monterey, California.

“I would guess there wasn’t a clear signature on radar for a warning in 2005,” Gass theorized about why the storm nearly two decades earlier failed to trigger the alarm.

Elsewhere in the West, some Lake Tahoe ski resorts received more than a foot of snow, while a 112-mph wind gust — around the strength of a Category 3 hurricane — was recorded at Mammoth Mountain resort not far from Yosemite National Park, according to the National Weather Service.

Meanwhile in upstate New York, more than 33 inches of snow reportedly fell in Orchard Park, which is frequently battered by lake-effect snow.  

The Midwest got its share of punishment from the skies as well, with a frigid ice storm creating dangerous driving conditions from Iowa into eastern Nebraska throughout the weekend.

The storm resulted in the death of a 57-year-old woman, who lost control of her pickup truck on Highway 30 and smashed into an oncoming truck, according to the Washington County Sheriff’s Office.
