Periods of gusty Santa Ana winds will continue into Thursday with weaker winds for Friday into early next week. Inland areas will continue to warm today. There will be slight cooling for Thursday and Friday with not much change for the weekend. Cooling is expected to spread inland next week as high pressure aloft weakens and onshore flow spreads inland. Some return of night and morning coastal low clouds and fog could occur as soon as late Thursday night.
For extreme southwestern California including Orange, San Diego, western Riverside and southwestern San Bernardino counties,
(today through Friday), Offshore flow for inland areas will continue through Thursday, but weaker and with less coverage of stronger east to northeast winds than recent days. For today, the stronger winds will be near and below the Cajon Pass with the stronger gusts to around 45 mph. For Thursday, the stronger and more widespread winds will be in the San Diego County mountains and far inland valleys with the stronger gusts to around 45 mph. Winds will then be weaker for Friday into early next week.
Warming will continue for inland areas today with the greatest warming of high temperatures for the mountains and valleys. High temperatures will be as much as 12 to 18 degrees above average today for the valleys with high temperatures ranging from the lower to mid 70s near the coast to the upper 70s to mid 80s for the valleys with the lower 80s for the lower deserts. There will be slight cooling on Thursday and again on Friday. Friday high temperatures will still be as much as 10 to 15 degrees above average for the valleys with high temperatures ranging from around 70 near the coast to the mid 70s to lower 80s for the valleys with the lower deserts around 80.
With weak onshore flow near the coast and a weak coastal eddy, some patchy night and morning low clouds and fog could return near the coast as early as Thursday night.
(Saturday through Tuesday), Not much change is expected with high temperatures for the weekend followed by a cooling trend next week as high pressure aloft weakens and weak onshore flow spreads cooling inland. Chances for measurable precipitation next week remain below 5 percent through Tuesday and below 10 percent through Wednesday. For the weekend into early next week, night and morning low clouds and fog may increase some in coverage, but with inland spread not expected much past coastal areas.
