SYNOPSIS

17/220 AM.

Near to slightly below normal temperatures are expected to continue today with low clouds and fog lingering into the afternoon across coast and some valleys south of Pt Conception. Gusty winds are expected at times across the mountains and deserts. Hazardous seas will affect the coastal waters over the next several days. Warmer temperatures are expected next week.

LONG TERM (WED-SAT)

17/220 AM.

One last day of weak offshore and minimal marine layer clouds will make Wednesday the warmest day of the week. Look for 1 to 3 degrees of warming with some vly max temps approaching 90.

Look for a benign upper level pattern to return Thursday and continue through Saturday. At the same time onshore flow will increase some each day. This will reinvigorate the marine layer stratus and most csts and some vlys will wake up to clouds each morning. Winds will not be an issue. Max temps will fall 3 to 6 degrees across the csts/vlys on Thursday. All areas will see 3 to 4 degrees of cooling Friday. Saturday's cooling of 1 to 2 degrees will bring max temps down into the upper 60s through the upper 70s across the csts and vlys.
