The famed Las Vegas Strip resembled a scene out of the Arctic on Thursday after a rare snowstorm turned the area into a winter wonderland.

The National Weather Service said there was 1 inch of snow at McCarran International Airport as of 4 a.m. Thursday.

Winter storm warnings had been posted for the Clark Mountains and most of Mohave County in Arizona through Friday morning. In Las Vegas, a winter weather advisory was issued through 4 a.m. Friday.

"Total snow accumulations up to 3 inches expected along the western and southern outskirts of the Las Vegas Valley as well as surrounding areas in Clark County," the NWS said. "For the Las Vegas Metropolitan area, rain may be mixed in with snow at times which would result in much less, if any accumulation."

The weather service said Las Vegas' half an inch of snow late Wednesday was the first measurable snow since the record keeping started. The famed "Welcome to Fabulous Las Vegas Nevada" sign was seen surrounded by snow.

Photos showed the city's casinos draped in snow as tourists took to the streets to capture the rare scene.

Las Vegas schools were open Thursday, and the Nevada Highway Patrol said some areas had snow and ice but all freeways were open.

The snow blanketed palm trees, and sent children outside to go sledding, FOX5 reported.

The snow snarled flights at the airport and traffic on highways.

"We don't have snowplows," airport spokeswoman Christine Crews told the Associated Press as she tallied about 100 flight cancellations due to snow and ice. "But we have airfield maintenance vehicles and sweepers ready to go."

Some flight delays reached more than two hours, the Federal Aviation Administration said.

Attorney Al Lasso, who moved to Las Vegas from New Jersey 25 years ago, snapped a photo of a ruler standing in 7 inches of snow on his back patio in the foothill community of Summerlin.

"When it snows in New Jersey, everyone stays inside. When it snows in Las Vegas, everyone goes outside and makes snow angels," Lasso he told the AP. "A lot of people have never seen snow here."

Las Vegas recorded a trace of snow on Feb. 10 as several storms moved through the region earlier this month. Some suburban foothill areas got several inches of snow on Sunday.
