SYNOPSIS

14/326 AM.

High pressure and offshore flow will bring very warm and dry conditions across the region through the weekend. Gusty Santa Ana winds will continue through at least Thursday, strongest through and below passes and canyon. Today will likely be the warmest day with a slow cooling trend starting Thursday.

LONG TERM (SAT-TUE)

14/236 AM.

A narrow upper high will sit over the west coast through the xtnd period. The high will weaken and hgts will fall from 580 dam Sat to 576 dam on Tuesday. At the SFC offshore flow will continue but it will be weaker than it is currently and wind advisories are unlikely at this time.

The lowering hgts and decreased offshore flow may allow for the return of some morning low clouds esp along the Central Coast (double esp western SBA county) and the Long Beach/Torrance area.

Max temps will slowly fall through the period. Csts and Vlys will fall from the mid 70s to lower 80s on Saturday to the upper 60s to mid 70s by Tuesday. Despite all of this cooling Tuesday's highs will be 4 to 8 degrees over normal.

The EC-AI is dry through the 26th and then only showers super light rainfall. The GFS-AI shows light precip on the 23rd and 24th but nothing showstopping.

MARINE

13/853 PM.

Periods of northeast winds will continue across nearshore portions of the Ventura, Los Angeles, and Orange, and San Luis Obispo county coasts through Saturday morning. These winds will create locally choppy seas, especially at their peak speeds in the early morning to early afternoon hours. Winds could reach 15-25 kts at times across the aforementioned areas, with highest likelihood from Channel Islands Harbor through Malibu and out to Santa Cruz Island during the early morning through early afternoon hours from Wed night through Sat morning.

There is a very low chance (10%) for northeast wind gusts of 15-25 knots to impact Avalon and Two Harbors over the next few days, but chances increase slightly (25%) late Wed through Sat morning.

Elsewhere and otherwise conditions will remain unseasonably mild into next week. Seas across the Outer Waters will continue to lower through tonight.
