SYNOPSIS

01/1141 PM.

Warm and dry conditions can be expected through most of this week. There will be some coastal low clouds and fog at times, but otherwise skies will remain mostly clear. There will be gusty onshore winds and some sundowners through most of the week.

LONG TERM (FRI-MON)

02/1221 AM.

Friday looks like a gloomy day. The ridge will weaken and the northerly flow will subside. An eddy will continue. This should bring low clouds to the csts and most vlys. The onshore push to the east and north will be between 5 and 8 mb which is strong enough to keep many beaches in the clouds all day long. Most max temps will fall by 2 to 4 degrees. Even with the cooling max temps will remain a couple degrees above normal (except for the Central Coast which will end up 2 or 3 degrees blo normal)

Large scale troffing moves in over the weekend and continues into early next week. At the sfc mdt-stg onshore flow will persist esp to the east and in the afternoons. Look for plenty of marine layer stratus in the mornings across the csts and many vlys. The nearshore areas will have slow clearing and some beaches will not see the sun. There will be stronger than normal seabreezes as well as gusty westerly winds across the Antelope Vly.

2 to 4 degrees of cooling will be followed by 1 to 2 degrees of additional cooling Sunday/ This will make Sunday the coolest day of the next 7 with max temps only in the upper 60s and 70s across the csts/vlys or 2 to 5 degrees blo normal. There will be a little warming on Monday as the trof weakens and the onshore push relaxes a touch.
