After bouts of intense heat brought record-highs and strained the power grid across Southern California, the region can expect to get a brief respite from high temperatures starting Friday, Sept. 30.
The high-pressure system responsible for the recent heat wave will be replaced this weekend by a cooling low-pressure system from the Pacific Northwest, according to NWS meteorologist Adam Roser.
However, the cool-down won’t be permanent; temperatures will warm up again by early next week, Roser said.

As a high-pressure system building off the Pacific Ocean strengthens into next week, warmer weather, clear skies, and dry conditions can all be expected, Roser explained. Still, the warming effect is expected to be slight compared to the extreme highs of recent months, Roser noted.
