It may be autumn in Southern California, but summer isn't ready to go away.
In possibly one last hurrah before cool fall weather moves in, the warm and toasty temperatures of summer will stick around this weekend and could hit triple digits.
Temperatures are expected to soar past 100 degrees in the valleys Friday, hitting 103 in Chatsworth and 104 in Woodland Hills. Residents in Ventura and Santa Barbara counties will feel the heat too, as temperatures reach the 90s, according to the National Weather Service.
Ojai and San Luis Obispo will be hot spots, with temperatures reaching at least 100 degrees.
But no other city in Southern California will be as hot, or rather as scorching, as the desert community of Thermal, where it will hit 109. Yes, that's 109, beating the notoriously warm Palm Spring weather by a degree.
So what's causing this autumn heat?
A high-pressure system is to blame for the sudden surge in temperatures, according to the weather service. The heat will likely stick around through the weekend.
By Sunday, an onshore flow should help to cool off Southern California slightly -- leaving prime weather conditions and clear skies for viewing the supermoon and total lunar eclipse.
Then on Monday, a low-pressure system moving though the Eastern Pacific toward Northern California will continue the cooling trend.
