Sub-Freezing Temperatures Grip The Southland Overnight

PALMDALE (CBSLA.com) — Sub-freezing temperatures gripped portions of the Southland overnight Wednesday into Thursday, the National Weather Service said.

The chilly weather is due to a cold air mass with diminishing winds and dry conditions, according to the NWS.

A frost advisory was in effect until 9 a.m. Thursday from San Luis Obispo County down through Los Angeles County.

Los Angeles basin and coastal communities have been excluded from the advisory.

The National Weather Service says the temperature dipped to 14 degrees in the high desert town of Lancaster Thursday morning, breaking a 2006 record low for the date. Neighboring Palmdale had 21.

Many other areas reported lows in the 30s and 40s. Los Angeles and San Diego hit 43.

"Temperatures will pose a threat to plant and crop life… as well as animals kept outdoors," NWS officials said.

Local stores like Home Depot say wood, space and patio heater sales are up over the last several days.

Afternoon highs Thursday are expected to reach the mid-60s across the LA area.

The next chance of wet weather will move into the forecast area Saturday through Monday.
