McCarran International Airport in Las Vegas is reporting flight delays of more than two hours and some cancellations due to snow and icy runways.
Airport spokeswoman Christine Crews said Thursday that more than 100 flights have been affected.
Meteorologist Chris Outler says a half-inch (1.3 centimeters) of snow was recorded overnight at the official regional weather station at the airport, which has no snowplows.
It was the first measurable snow at the airport in 10 years, but much less than the 3.6 inches recorded on Dec. 17, 2008.
Outler says there won't be enough snow to build snowmen at the "Welcome to Las Vegas" sign. But some suburban foothill areas have several inches.
