A cold front is starting to hit northern CA this afternoon and evening and it’ll dissipate as it pushes thru the Central Coast into Friday. This along with the offshore flow ending has promoted a lot of additional cloud cover in the area. This help temps down today in the 60s for nearly everyone. Tonight it’ll help hold up the overnight lows in the 40s.
Partly cloudy skies are on the way for Friday with highs in the 60s, mid to upper 60s for the coastal valleys while inland valleys will be the low to mid 60s.
Temps look to cool a degree or two over the weekend with continued partly cloudy skies (with some night and morning fog possible in the interior valleys).
Late Monday into Tuesday another storm system will push into CA. Models disagree on the impact. Christmas Eve looks to see increasing clouds but Christmas Day rain is possible. The American GFS model likes little to no rain while the European model likes as much as .50″. The track of the low is critical, a path over the ocean would allow the higher rainfall while an inland path could mean no rain at all. Right now I am going with a showery system with light to .50″ in the range. I hope to get more precise on the range as we get closer.
High surf will continue thru next week since there is plenty of activity in the north Pacific. Right now 10-12ft surf is happening and an advisory is active into Friday.
