A cold air mass parked over the Southland will keep temperatures on the low side until the start of a warming trend later this week.
No frost or freeze advisories were in effect in Los Angeles County this morning but freezing temperatures were recorded in the Antelope Valley, and several newly issued wind advisories were in effect.
A wind advisory was scheduled to be in effect until 9 a.m. today in the San Gabriel and Santa Monica mountains, the San Fernando and Santa Clarita valleys, and the Los Angeles coastal zone, which includes beach cities, metropolitan Los Angeles, the downtown area and the Hollywood Hills.
The National Weather Service forecast sunny skies today and highs of 42 on Mount Wilson; 46 in Palmdale; 47 in Lancaster; 55 in Saugus; 58 in Mission Viejo; 59 in Avalon, Pasadena and Burbank; 60 in Laguna Beach, San Clemente, Yorba Linda, Irvine and San Gabriel; 61 in Long Beach, downtown L.A., Newport Beach and Woodland Hills; and 62 at LAX and in Fullerton and Anaheim.
Highs are expected to be marginally higher Wednesday — up to 3 degrees higher in some communities — and rise again Thursday, reaching highs around 5 degrees higher than today in several spots. On Friday, several L.A. and Orange County communities will climb back into the 70s.
