SYNOPSIS
19/722 PM.
High pressure and offshore flow will bring warm and dry conditions to the area through midweek, along with breezy northeast winds at times across Los Angeles and Ventura Counties. A significant cooling trend is expected to begin Wednesday, with light rain or drizzle possible Thursday.
LONG TERM (FRI-MON)
19/216 PM.
After Thursday high pressure will rebuild over the West Coast for dry conditions and a slow warming trend through early the following week. There are some indications that offshore flow could return as soon as Saturday or Sunday with some models indicating a return to moderate offshore flow and Santa Ana winds, but the upper pattern suggests minimal upper level support so most likely any offshore winds would be below advisory levels with minimal impacts.
As far as rain chances go, ensembles are still picking up on some signals somewhere around the 28th-30th, though more recent solutions are pushing that back to early Feb. And the vast majority of the solutions favor light to at most moderate rain with again minimal impacts.
