What we saw Friday will likely repeat on Saturday. A lot of low clouds with areas of fog and drizzle were at the beaches and coastal valleys this morning. Some drizzle was actually measurable this morning.
The thermal trough of low pressure (cause by inland heating) along the California coastline is generating light onshore winds which leads to a lot of marine cloud cover with night and morning fog and drizzle. The beaches could remain mostly overcast Saturday.
Stronger afternoon northwesterly winds on Sunday and Monday will produce clearing along the coastline during the afternoon. Inland valley temperatures will increase to the mid-90s on Sunday.
A weak low-pressure system will move into the Central Coast by Tuesday. This system will produce more marine clouds with night and morning fog and mist and seasonal temperatures.
