SYNOPSIS

27/745 PM.

Skies will feature high clouds at times through Wednesday afternoon, then should clear up for most of the week. High temperatures will climb each day through Saturday, with temperatures warming into the 70s and 80s. Breezy Santa Ana winds are likely late Wednesday into the weekend.

LONG TERM (SAT-TUE)

27/143 PM.

After another very warm day Saturday with highs 10-15 degrees above normal, a rapid cooling trend will begin Sunday as high pressure gives way to a weak trough that will bring a return to light onshore flow and cooler temperatures. Highs will still be above normal but only by 3-6 degrees.

The upper level pattern in early February has the same look and feel as the last few weeks with high pressure being the dominant feature over the eastern Pacific. The 12z ensemble runs from the GEFS, GEPS, ENS, and the AI models all favor a persistent ridge at least through the first week in Feb. And even looking beyond that through the 12th of Feb there is really very little change that would bring southern California any meaningful rain.

For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. There is a 50-60% chance of SCA level northeast winds Wednesday into Thursday. Seas may exceed 10 feet as early as Wednesday night and persist near or above 10 feet through Friday.

For the Inner Waters south of Point Conception, moderate confidence in current forecast. SCA level winds are likely across the western Santa Barbara Channel with a 15 percent chance of brief SCA level gusts spreading into the eastern Channel Islands through later tonight. Areas of Santa Ana (N-NE) winds are expected for the nearshore coastal waters off the Ventura County Coast to Malibu each morning through Saturday.
