A run of mild weather ahead

Posted at 3:55 PM, Sep 21, 2018

Onshore flow returned today and temps took an expected hit but pleasant temperatures look to hold on into the weekend. I think the thing most people will notice will be coastal low clouds Friday night into Saturday and looks like it will linger at beach communities. Some beaches may not clear the clouds and where clearing happens clouds look to fill in again Saturday evening into Sunday. I like better clearing on Monday.

Inland highs will still manage lower 90s for the weekend while coastal valleys will hit the mid 70s with beaches in the mid to upper 60s (expect for spots where clouds linger, those beaches like Morro Bay may only manage low 60s). I like slightly above average temps through most of next week.

Model runs indicated earlier this week that October could begin with a wet pattern, both the American GFS and the European Model are now backing off. There is a trough that will develop in early October and it could cause light showers but I don’t think much of it yet.

Fall begins at 6:54 pm on Saturday with the equinox. During the equinox, the Sun crosses the “celestial equator.” Imagine a line that marks the equator on Earth extending up into the sky above the equator from north to south. Earth’s two hemispheres receive the Sun’s rays about equally. The Sun is overhead at noon as seen from the equator, so at this point, the amount of nighttime and daytime (sunlight) are roughly equal to each other.
