Fog and marine layer are filling in over the coastline and coastal valleys Wednesday morning, especially in areas north of Point Conception. The fog could stick around through about 10 o'clock on Wednesday morning before burning off.

Temperatures along the coast will be slightly cooler Wednesday. Low clouds and onshore flow will keep most coastal areas around the low to upper 60s. Coastal valleys between SLO and Santa Barbara Counties will trend down by a few degrees. with maximum temperatures hovering around the low to mid-70s. The inland valleys will stay fairly warm with temperatures from the upper 70s to the low 80s, which is above seasonal norms. Steady offshore winds are in the afternoon forecast and could reach 20 miles per hour at their peak.
Looking ahead to the weekend, a ridge of high pressure will swing over the state, increasing daytime highs before a slight cool down at the start of next week.
