Southern California is experiencing extraordinary weather conditions. Wednesday, persistent offshore winds pushed the temperature to a record-breaking 100 degrees in Santa Barbara. "Devil winds" also developed Wednesday evening in Los Angeles, where the mercury jumped from 78 at 5 p.m. to a balmy 89 degrees by 8. The mechanism fueling these winds remains in place today with high pressure building to the north and northerly gradients aligned across Santa Barbara and also into western Los Angeles County.

Because of these conditions a high-wind warning will remain in effect through Friday morning in Santa Barbara and the mountains of Los Angeles and Ventura counties. Winds could gust to 65 mph across these areas, especially this afternoon and evening.  A wind advisory is also in effect for the San Fernando and Santa Clarita valleys, where winds could reach 45 mph.

Blue skies and hot temperatures will be the norm today for most of the region. Highs will again be near the century mark in the valleys. At the beaches, temperatures are expected to hover around the mid-70s. Winds will pick up this afternoon, increasing in the evening before diminishing Friday.

Friday, the dynamics driving these winds will start to erode, although it will remain breezy all day. Temperatures are forecast to remain in the 80s and 90s. Cooler weather should return this weekend as onshore breezes bring relief from the heat.
