Cold front blows in

The cold front that stole like a Grinch into the Santa Clarita Valley behind Christmas rains will linger until Sunday, delivering a two-punch combination of chilly days and freezing nights, a National Weather Service meteorologist said Friday.

"Behind the Christmas showers was a big cold front," meteorologist David Gombers said.

The cold front ushered in frigid air from Canada and the Gulf of Alaska that held daytime temperatures below 50 degrees Friday with northerly winds, Gombers said. The snow level dropped as low as 2,500 feet on Thursday.

"The calm winds and clear skies are contributing to radiational cooling," Gombers said. Radiational cooling happens when there is little cloud cover to hold the heat generated during the day.

A weak high-pressure system is expected to move into the Santa Clarita Valley during the weekend, bringing a return to more seasonable daytime temperatures in the mid- to upper- 50s Sunday and low 60s Monday, Gombers said. But nighttime lows will still hover near freezing, he said.
