The fog and marine layer will be patchy throughout the morning over the coastal valleys and beaches. Along with the fog, drizzle could also be a factor throughout the morning commute before the fog lifts late morning.
Ten to 25 mile per hour northwesterly winds will develop by the afternoon, which will clear out most of the cloud cover from the morning hours.
While the interior valleys will be somewhat cooler and from the mid to upper 80s Friday, temperatures will again heat up to the mid-90s by the weekend. The coastal valleys will be around the mid-70s to mid-80s and the beaches will warm up to the mid to upper 70s.
