SYNOPSIS

18/205 AM.

Warmer temperatures are expected this week with some locally breezy Santa Ana winds this morning. The warmest day will be Wednesday with slow cooling the rest of the week along with a return of night and morning low clouds and fog.

LONG TERM (FRI-MON)

18/1234 PM.

A fairly quiet pattern will continue through the remainder of the forecast period, with weak winds aloft. Aside from a slight decrease in temperatures Friday and possibly Saturday, there will be little change in sensible weather day-to-day. Widespread temperatures in the 70s to low 80s will be common across coastal valleys and basins, slightly cooler at the immediate coasts with mid 60s to low 70s likely. Inland valleys will see highs reach the mid to upper 80s, with low 90s possible, especially Friday.

A more robust marine layer is likely to develop each night through morning, with some coastal areas struggling to clear each day. Marine layer clouds will try to move into some of the coastal valleys by this weekend, as onshore flow increases into the weekend. Onshore flow will then stay relatively steady through Monday. Moderate southwest winds across the Antelope Valley and foothills by this weekend, which would lead to elevated fire weather concerns each afternoon in the far interior.
