SYNOPSIS
16/107 PM.
High pressure and offshore flow will bring very warm and dry conditions across the region through the weekend along with locally gusty northeast winds at times across Los Angeles and Ventura Counties. A slow cooling trend will begin today, but above normal temperatures are expected at least into early next week.
LONG TERM (TUE-FRI)
16/140 PM.
Most of the ensemble solutions suggest the primary cooling day will be Wednesday when high pressure aloft finally breaks down and onshore flow returns. This should bring temperatures down to the 60s to low 70s in most areas through the end of next week with possibly some marine layer return as well. Chances for rain later next week have been decreasing over the last few days but there are still about 20% of the ensemble solutions that support light rain either late Friday or Saturday.
