Southern California's week of unusually cold weather continued Wednesday with overnight temperatures in valley areas dipping into the teens, as Colorado started to dig out from record snow.
The National Weather Service issued a frost advisory for California's San Gabriel and Santa Clarita valleys until 9 a.m. Wednesday. Forecasters warned that freezing temperatures risk harm to pets, livestock and sensitive vegetation.
Just before dawn the temperature in Lancaster, in the Antelope Valley north of Los Angeles, was 19 degrees. The frigid weather is a result of a dry, cold air mass that descended on the region after weekend storms moved out.
Meanwhile, areas around Denver got nearly a foot of snow in a storm larger than what forecasters had predicted, Fox 31 reported. An estimated 7.7 inches of snow fell on Denver International Airport on Tuesday, breaking the record for that day.
Overnight freeze warnings were issued for the San Joaquin Valley and Central Coast counties in California.
Drivers were urged to use caution in mountain areas, where a wind advisory is in effect through 10 a.m. Forecasters predicted wind gusts topping 45 mph.
