Synopsis
17/117 PM.

Dry but cooler weather with increasing low clouds and fog during the nigheights and morning is expected through Friday as a weak low pressure system moves into the area. A warming trend is expected for the weekend before cooler temperatures return next week.

Short Term - Today through Saturday
17/144 PM.

A relatively quiet period of weather coming up over the next several days. A weak trough is approaching the West Coast with a ton of high clouds. Otherwise the main impact will be increasing onshore flow and marine layer stratus (as those near the coast south of Pt Conception today can attest to) and cooler temperatures through Friday. Forecast soundings only indicate minor deepening of the marine inversion tonight so there will still be areas of dense fog near the coast and just very little if any valley fog intrusion expected. The cooler onshore flow mainly just reached the coastal areas but by tomorrow and Friday cooling will reach all the way into the interior with highs topping out in the mid to upper 70s versus the 80s today.

The cooling trend will reverse over the weekend with a brief but effective ridge over California this weekend. Temperatures should bounce back to the 80s inland with a 10-20% chance of an isolated 90 or two in the warmest valleys Sunday.

Long Term - Sunday through Wednesday
17/207 PM.

The weekend ridge will be short lived as the next weak trough is expected to hit the West Coast late Monday and likely remain in place through the week. This will generate significant cooling across the area with a likely return of a deep marine layer by mid to late week. Ensembles have been hinting at some precipitation chances as well, though those were likely associated with a small percentage of solutions that showed the upper low cutting off and dropping much farther south along the coast. A majority favor an open wave solution with the upper low over Oregon and extreme northern California. There are some deeper trough solutions later in the week and into next weekend that could squeeze out some light precipitation by next weekend, probably more in the form of deep marine layer drizzle. In any case, it looks like a long duration of well below normal temperatures across the area starting next week.

Marine
17/900 AM.

A very shallow marine layer will continue to bring dense fog to most waters south of Point Conception this morning, and could linger through the afternoon or evening. Improved but still reduced visibility is expected by Thursday.

There is a 60 percent chance of Small Craft Advisory conditions for the offshore waters off the Central Coast this afternoon and evening. Otherwise, high confidence in generally light winds through Friday. Southeast winds around 10 knots are expected each morning from the Santa Barbara Channel to Orange County, with some local enhancements through the Anacapa Passage and San Pedro Channel.

Northwest winds will be increasing over the weekend.
