Cold and Rainy Weather Will Close Out September

Friday will be a transition day as we move into a cooler weekend with rain chances. The day will start off nice with some sunshine and mild temperatures around the bay, but we’ll be fighting clouds later. Clouds will increase into the overnight with some drizzle possible, then we’ll see a chance of rain into Saturday. A trough of low pressure will dig down the coast bringing a much cooler air mass and a decent tap of moisture. It will be over us on Saturday and the unstable atmosphere will be ripe with showers and perhaps a thundershower or two. The trough will begin to move east on Sunday, but a shower or two may linger behind it while sunshine and temporaries begin to increase. Then, high pressure builds in from the west and light offshore flow will warm temperatures significantly next week!


…for Coastal Waters from Point Pinos to Point Piedras Blancas California out to 10 nm extended until 9PM Friday.

*Northwest winds 15 to 25 kt with gusts up to 35 kt expected.

*Strong winds will cause hazardous seas which could capsize or damage vessels and reduce visibility.

Mariners should alter plans to avoid these hazardous conditions. Remain in port, seek safe harbor, alter course, and/or secure the vessel for severe conditions.

Friday: Partly cloudy early, becoming mostly sunny by noon, then increasing clouds through the rest of the day. Mild, with coastal highs in the mid 60s to low 70s and mid 70s to low 80s inland. Breezy north-northwesterly winds at times, getting gusty around river mouths and in the valleys.

Overnight: Partly cloudy, then mostly cloudy heading into the evening. Drizzle is possible before rounds of showers move in early morning. Showers will be scattered with mainly light rain. However, individual cells could produce brief moderate rain and gusty winds. Lows will be warmer overnight due to cloud cover, expect temps in the mid to upper 50s across the area.

Saturday: Mostly cloudy with scattered showers and a chance for a thundershower. Cool day, highs in the 60s for most areas, with a few 70s inland. Rain accumulation 0.05-0.10” for most areas, but some spots may approach a quarter of an inch in the mountains. Breezy, gusty at times.

Extended: A few showers may linger on Sunday, but otherwise we’ll be clearing with warmer temperatures into next week. In fact, it’s going to get quite warm by Tuesday and may stay that way through the end of the week.
