SYNOPSIS

27/247 AM.

Skies will be partly to mostly cloudy through Wednesday with high temperatures about 6 degrees above normal. Santa Ana winds will develop on Thursday when skies will be sunny and most high temperatures will be in the 70s. Friday will be the warmest day with cooler and cloudier conditions arriving for the weekend.

LONG TERM (FRI-MON)

27/245 AM.

Friday will be the warmest day of the next 7 as a ridge pokes into the area from the SW, Hgts will rise to 584 dam. 2 to 4 mb of offshore flow will keep the low clouds away and the ridge will insure that the rest of the skies are clear. The rising hgts and offshore flow will combine to raise temps 2 to 3 degrees which will push vly and some cstl highs into the 80s.

Picture Postcard weather will continue into Saturday with little change in the sensible weather or synoptic parameters.

The ridge will break down on as troffing approaches the state. Hgts will fall to 574 dam (or even lower if the GFS solution is correct). The offshore flow will weaken substantially and may even turn onshore in the morning. The fall hgts and onshore trends will likely combine to produce some morning low clouds along the coast. The trof will bring enough mid and high clouds to make the days partly - ocnly mostly cloudy. Max temps will fall 3 to 6 degrees Sunday and 2 to 4 additional degrees on Monday. Monday's highs will range from the mid 60s to the mid 70s across the csts and vlys.

Both the AI runs of the GFS and EC show that dry weather will likely prevail through at least February 9th.

AVIATION

At 1005Z at KLAX, there was no marine layer nor an inversion.

High confidence in TAFs, except KPRB where there is a 20 percent chc of VFR conds persisting through the period.

KLAX...High confidence in TAF. Good confidence that any east wind component remains below 6 kt.

KBUR...High confidence in TAF.

MARINE

27/313 AM.

For the Outer Waters, moderate to high confidence in current forecast. Winds and seas are expected to remain below Small Craft Advisory (SCA) levels through tonight. Winds are expected to increase Wednesday, with a 40-60 percent chance of SCA gusts, strongest across PZZ673, and possibly continuing into Thursday evening. Seas will also increase starting on Wednesday, reaching 10 to 12 feet on Thursday. SCA level seas will persist into Friday, before decreasing for the weekend.

For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. There is a 20-30% chance of SCA level northeast winds Wednesday into Thursday morning. 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. Areas of offshore (N-NE) winds are expected for the near shore coastal waters off the Ventura County Coast to Malibu each morning through Saturday. These winds should mostly remain below SCA levels, but Thursday and Friday mornings have the best chance to see local SCA level gusts.
