    As of 06:00 Hours we have high overcast, a stratus layer and unlimited visibility.


For the forecast, high pressure offshore will maintain moderate to strong onshore flow into next week. The weak low pressure to the Southeast will continue to bring a chance of showers into the mountains. The pattern will be slightly different than the past week where it will likely be cloudier in the mornings breaking in the afternoons with the chance of rain later in the day into the night time hours. The marine stratus layer has moved onshore and will likely lift later this morning with day time heating.

    Still significant moisture to our South and East.

    Will be mostly cloudy today.

    High pressure North and West low Southeast.
