SYNOPSIS

03/236 AM.

Warm and dry conditions can be expected through most of this week. There will be plenty of morning low clouds and fog across most of the coasts and many valley areas, but otherwise skies will remain mostly clear. Northerly winds will affect areas of southern CA tonight.

LONG TERM (SAT-TUE)

03/236 AM.

Troffing and mdt-stg onshore flow will dominate the xtnd period. This will bring very June like conditions to the area on all 4 days. Onshore flow will be strongest over the weekend and the low clouds will penetrate deep into the vlys and will likely not clear at all from many beach and nearshore areas while the rest of the csts/vlys see slower than normal clearing. 3 to 5 degrees of cooling Saturday will be followed by 1 to 3 additional degrees on Sunday. Sunday's max temps will end up in the upper 60s to mid 70s across the csts and a degree or 2 either side of 80 in the vlys. These max temps are mostly 2 to 4 degrees blo normal.

The onshore flow relaxes some on Mon and Tue and this will bring earlier clearing times for the marine layer stratus as well as a few degrees of warming each day.
