California citrus crops affected by cold temps

Californians are hoping for a warmer weekend after a Thanksgiving cold snap broke or tied cold-temperature records -- some more than a century old -- up and down the state.

The National Weather Service reports that San Francisco's low of 42 degrees on Thursday tied a record set back in 1892. Across the bay in Oakland, 36-degree daytime temperatures shattered the old record of 42.

The mercury in Los Angeles dropped to 42, tying a 1946 record.

Stockton saw a record low temperature of 27 degrees Thursday morning, while Sacramento tied a record low of 30.

Subfreezing temperatures in California's Central Valley citrus growing region threatened to damage the billion-dollar crop. But growers working through the night used warm water and wind machines to keep the cold at bay.
