Frost Advisory Issued As SoCal Dives into Chilly Temperatures

A frost advisory was in effect in several parts of Southern California as a dry, cold air mass brought sub-freezing temperatures overnight and in the early-morning hours.

The advisory was issued for the coldest areas, which were expected to be in the Antelope Valley, including Lancaster. Chilly temperatures were also to the north, the interior valleys of San Luis Obispo and Santa Barbara counties.

The National Weather Service said the frost advisory would remain in effect in the Antelope Valley from 3 a.m. to 9 a.m. Wednesday, and a freeze watch will be in force from late Wednesday night through Thursday morning.

Winds picked up to about 21 mph making temperatures feel colder in the Lancaster area Wednesday morning.

An NWS statement said temperatures of between 32 and 35 degrees Fahrenheit were expected in the Antelope Valley Wednesday morning until the frost advisory expires. Temperatures of between 27 and 32 degrees were expected tomorrow morning.

The NWS statement said, "sensitive plants and crops can be damaged and unsheltered animals can be harmed,'' the statement said, adding that animals should be brought indoors or placed in a barn, and measures need to be taken to protect sensitive plants.

Highs today were expected to be in the upper 50s in the Antelope Valley and the upper 60s in much of the rest of the region.
