Californians can get ready for a warm weekend. The area most likely to see numerous record highs challenged on Friday and Saturday is Southern California, west of the mountains.
The reason that Southern California will see the most amount of records broken or challenged is that there will also be an offshore flow in place.
An offshore flow means that the air is flowing from inland areas to the coast. When the air flows down the western slopes of the mountains west of Los Angeles and San Diego, it warms and boosts temperatures in Southern California.
The air flowing in that direction will keep marine air out of Southern California. The ocean air can often bring low clouds, fog and cool air.
With that offshore flow will also come gusty Santa Ana winds. This Santa Ana wind event will be a weak to locally moderate event with gusts to around 35 mph. The wind will blast through and below the passes and canyons late Thursday through Friday morning. The mountains will see higher gusts.
This warmth will not last long. Cooler air will return Sunday as a storm system moves from the Northwest into the Rockies and breaks down the ridge.
