Synopsis
A weak trough of low pressure will bring a little stronger onshore flow with cooling into Tuesday with westerly wind gusts to 45 mph in the mountains and deserts for this afternoon and evening. The marine layer will deepen with night and morning coastal low clouds and fog spread farther into the valleys. Warmer inland on Wednesday with weak high pressure aloft, then a little cooler for Thursday and Friday. Then a warming trend for next weekend into early next week as low pressure weakens across the western states with the marine layer becoming shallower and onshore flow weaker.

For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties
Short Term - Today Through Wednesday
A weak trough of low pressure is moving from southern California into Arizona early this morning with a second weak trough of low pressure moving inland through southern California late Tuesday and Tuesday night followed by high pressure aloft for Wednesday.

Onshore flow and a weak coastal eddy will continue a slow deepening trend for the marine layer with night and morning coastal low clouds and fog spreading into the western valleys this morning and farther into the inland valleys for tonight into Tuesday morning.

It will be a few degrees cooler today again Tuesday with Tuesday high temperatures a few degrees below average for the coast into the valleys and a few degrees above average for the deserts into the mountains. A little warmer for Wednesday with greater spread in the warming in the high temperature guidance for the coast and valleys tied to uncertainty in the depth of the marine layer.

Onshore flow will bring gusty west winds to the mountains and deserts this afternoon and evening with the stronger gusts to 45 mph.

Long Term - Thursday through Sunday
Not much change or slightly warmer on Thursday, then a little cooler for Friday as a trough of low pressure moves inland to the north strengthening the onshore flow. For next weekend, the coolest model cluster maintains greater low pressure troughing over the southwest states with that cluster heavily weighted with ensemble members of the GFS. The deterministic NBM has a slow warming trend through the weekend with temperatures peaking Sunday or Monday depending on location.

Marine
Occasional northwest wind gusts exceeding 20 knots around San Clemente Island are expected this afternoon and evening. Otherwise, no hazardous marine conditions are expected through Friday.

Skywarn
Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.
