Coastal low clouds will continue each night and morning at the coast and in portions of the valleys. Clouds will clear from most areas late morning each day, but will likely stick around the beaches into the afternoon at times. Onshore winds will gradually weaken throughout the day today, though gusts to 40 mph continue to be possible through this evening. Drizzle is possible west of the mountains Saturday morning, though little to no accumulation is expected at this time. A gradual warm-up is in store for much of next week, with high temperatures 5 to 10 degrees above average.

For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties
At 8 AM, low clouds and fog covered much of the coastal basin, extending into portions of the coastal mountain slopes. Drizzle has been reported in numerous locations, and even a few sites recorded measurable precipitation. Low clouds will slowly clear out of the valleys later this morning, but coastal areas are unlikely to clear out today.

Gusty west winds have likely peaked in strength early this morning, and will gradually decrease throughout the day. A few locations below the San Gorgonio Pass recorded gusts in excess of 50 mph. Elsewhere, gusts peaked around 40-45 mph.

The trough responsible for this gloomy and windy weather will continue to persist over the West today and Saturday. The coolest day of the week will likely be today, with high temperatures 5 to 15 degrees below average, with highs only reaching into the upper 60s to low 70s west of the mountains today.

A persistent coastal eddy will continue to bring low clouds and fog to the valleys each night and morning through the weekend. Another repeat of morning drizzle is likely Saturday morning, as the marine layer deepens slightly tonight. A few locations may record measurable precipitation, but overall no accumulation is expected.

As the trough pushes east late Saturday through Sunday, a ridge will nudge into SoCal behind it. This will result in a slow warming trend Sunday into mid next week. Latest models runs are showing this ridge not quite as strong as previous runs, which may limit how hot it gets next week. Currently, ensembles are in fairly good agreement that Wednesday will to be the warmest day for locations west of the mountains, and Thursday for the mountains lower deserts. Temperatures in the lower deserts will range between 105-109 degrees, and widespread 90s are expected for the inland valleys and High Desert. Persistent onshore flow will keep coastal areas cool, in the upper 60s to low 70s next week.

Models and ensembles are showing this high weakening around Friday, with a trough passing to our north. This would increase onshore flow and bring cooler temperatures to the region. Exact details on the timing of the cooldown are uncertain at this time.

No hazardous marine conditions are expected through Tuesday.

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