.SHORT TERM (Today through Wednesday), Strengthening high pressure to the east will bring a warming trend through Wednesday with high temperatures on Wednesday a few degrees above average near the coast and 5 to 10 degrees above average for inland areas. High temperatures on Wednesday will range from the lower to mid 70s near the coast to the 90s for the Inland Empire with 108 to 112 for the lower deserts.
For Tuesday and Wednesday, there will be widespread moderate HeatRisk for the deserts with locally major HeatRisk for portions of the lower deserts on Wednesday. There will also be moderate HeatRisk on Tuesday and Wednesday for mountain elevations below 5500 feet and for portions of the Inland Empire.
Night and morning coastal low clouds will spread into the western valleys late each night, though with some decrease in marine layer depth through Wednesday. Some mid and high level moisture and clouds could be drawn into the area from the southeast for late Tuesday and into Wednesday.
Strengthening high pressure to the east will bring a warming trend through Wednesday with moderate HeatRisk for Tuesday and Wednesday for the deserts, mountain elevations below 500 feet, and portions of the Inland Empire. High temperatures will warm to 5 to 10 degrees above average for inland areas. This will be followed by a cooling trend through next weekend with high temperatures for next Sunday as much as 8 to 12 degrees below average for the valleys and coastal slopes of the mountains.

(Thursday through Sunday), High pressure to the east will begin to slowly weaken and the axis move slowly southward as a closed low pressure system off the southwest coast of British Columbia directs a stronger jet stream across the western states to the north. The onshore flow across southern California will weaken with cooling spreading inland. On Thursday, moderate to locally major HeatRisk will continue for the lower deserts.
By Sunday, high temperatures will be as much as 8 to 12 degrees below average for the valleys onto the coastal slopes of the mountains. High temperatures for next Sunday will range from around 70 near the coast to the upper 70s to mid 80s for the Inland Empire with the upper 90s to 104 for the lower deserts.
Night and morning coastal low clouds will spread inland into portions of the valleys late each night.
220930z, Coast/Valleys, Low clouds with bases 1300-2000ft MSL have moved in over the San Diego coast and pushed into adjacent valleys. Clouds are beginning to form in inland Orange County and are expected to increase in coverage over the next few hours. The Inland Empire may see some low clouds overnight but would be patchy in nature. Low clouds will begin their retreat after 15Z, clearing the coast by 17-18Z. Cigs return 01-03Z Tuesday with slightly lower bases expected.
Mountains/Deserts, VFR conditions expected through the TAF period with passing high clouds AOA 20000ft MSL.
No hazardous marine conditions are expected through Friday.
Surf heights have lowered slightly, but may become elevated again by Wednesday as fresh long-period southerly swell moves in. Strong rip currents will remain possible through the upcoming week.
