Strong onshore flow is creating a deep marine layer with areas of fog and patchy drizzle this morning. Northwest winds have returned ahead of our next weather-maker and we'll begin cooling, quickly, dropping 5 to 10 degrees below average by this weekend.
A Wind Advisory goes into effect at 8 pm, lasting until 5 pm Saturday for the mountains and desert. Winds will gust upwards of 25-30 mph from the coast to inland valleys and 40-55 mph in the mountains and deserts.
While a few light showers are possible as early as 5 p.m. along the coast, steady rain won't begin until closer to 10 p.m., well after trick-or-treaters are home safe. The bulk of the rain arrives after midnight Friday through Saturday morning with showers continuing through the day. Isolated light showers may continue into Sunday morning in the mountains, as the trough exits to the east.
Forecast rain totals will be highest in the mountains from 0.25 to 0.75 inches with 0.10 to 0.25 inches to the coast and valleys with maybe a trace to a few hundredths in the deserts.
Snow levels will also drop on Saturday behind the cold front with a dusting to a couple of inches of snow possible above 6,500 feet. A Winter Weather Advisory has been posted for the mountains of Riverside and San Bernardino Counties.
