Southern California sees overnight thunder, light rain as temps dip below average

A few showers and thunderstorms hit Southern California overnight as cooler weather moved into the region for Wednesday.

“Definitely a cooler air mass pushing through,” KTLA Meteorologist Henry DiCarlo said Wednesday morning. “Yesterday we were above the average … It’s going to be a struggle to get to the average today.”


The low-pressure system will deepen the marine layer, bringing a continued chance for light showers and even a possible thunderstorm Wednesday, the National Weather Service (NWS) said.

“Most of the energy is in through Central and Northern California,” Henry said. “Maybe we get a little activity out in the high desert, and that’s why we get a chance of thunderstorms.”

A viewer in Victorville emailed KTLA Wednesday morning to report a thunderstorm that “felt like a tornado” hit the area. “Felt like I was back home in Dallas Texas all over again,” Gilbert Hernandez said.

KTLA’s radar shows moisture over Southern California on Oct. 22, 2025.

Thunderstorm chances are expected to dissipate later in the afternoon before a high-pressure ridge brings warmer temperatures back to the region on Thursday and Friday.

Another cooldown is slated to arrive this weekend.
