Temperatures will dip sharply Wednesday after several days of above-average heat.
A high of 71 degrees is expected in downtown Los Angeles., down from 77 on Tuesday. Woodland Hills is forecast to top out at 82, down from 93, and Lancaster is forecast to hit a high of 91, down from 98. The fall in temperatures results from a trough of low pressure along the coast and an increased onshore flow.
Temperatures rose considerably over recent days. On Saturday, downtown LAhit 94 degrees, 20 degrees above normal. There were also a few records set, including at LAX on Friday and again Saturday, when the high of 93 topped the previous record for a May 20th -- 87.
A wind advisory will be in effect from 2 p.m. until 9 p.m. in the Antelope Valley, where southwest-to-west winds will blow at sustained speeds of between 20 and 30 miles per hour, with gusts of between 40 and 50 mph. The wind could prove challenging for drivers in high-profile vehicles, and blowing dust could reduce visibility.
Weaker winds are expected elsewhere in Los Angeles County, including 15 to 25 mph in the San Gabriel Mountains and the Santa Clarita Valley, 10 to 20 mph in the Santa Monica Recreational Area, and 15 mph in the San Fernando and San Gabriel valleys and metropolitan Los Angeles.
The NWS forecast partly cloudy skies in Los Angeles County and highs of 66 in Avalon and at LAX; 68 in Long Beach; 71 in Downtown L.A.; 72 on Mount Wilson; 77 in Burbank and San Gabriel; 79 in Pasadena; 82 in Woodland Hills; 83 in Saugus; 89 in Palmdale; and 91 in Lancaster.
Partly cloudy skies were also forecast in Orange County, along with highs of 65 in Newport Beach and San Clemente; 66 in Laguna Beach; 75 in Anaheim and Irvine; 76 in Mission Viejo; 77 in Fullerton; and 79 in Yorba Linda.
While some communities will stay at the same temperatures Thursday, others will go down sharply: Saugus from 83 to 66, Lancaster from 91 to 78, Palmdale from 89 to 77 and Woodland Hills from 82 to 69. A warming trend will get underway Saturday.
