WEATHER STORY
We will remain sandwiched in between two areas of high pressure through mid-week. These features are dominating the weather across the East Pacific and the Western U.S. Here on the Central Coast, this has meant tranquil, seasonable weather for us. Weak low pressure will slowly strengthen on West Coast through the end of the week, eventually allowing a weather system to sneak in from the north this weekend. It will likely bring much-needed rain to the Pacific Northwest all the way down into Northern California. How far south it gets is a little more difficult to pinpoint at this moment. The actual cold front will likely be in the process of washing out as it reaches the San Francisco Bay Area. At the moment, I think we may just see an increased chance of drizzle Sunday morning, but a lot can change in the meantime. Beyond that system, offshore winds are possible on the coast which could lead to higher fire danger.
Rest of Wednesday: Low clouds will stick around the coast for most of the day with partial clearing at times. Inland areas will be sunny after morning valley clouds. All areas will be slightly cooler with coastal highs in the 60s and 70s to low 90s inland. Breezy for valleys in the afternoon and early evening.
Overnight: Low clouds thicken a bit and head a bit farther inland. Fog possible, especially in the coastal hills. Patchy drizzle. Lows in the 50s.
Thursday: Even cooler and cloudier on the coast with highs mainly in the 60s. Even inland areas will be cooler, though sunny in the afternoon with highs mainly in the 70s-80s. Winds pick up for inland valleys in the afternoon and evening.
Extended: Temps stay cool on Friday with a deeper, more stable marine layer in place. A weather system will then descend the West Coast into the weekend with a dissipating frontal boundary arriving locally into Sunday morning. Temperatures will warm a bit with southerly flow ahead of the system and then further with disruption of the marine layer. Some light precipitation possible—mainly drizzle Saturday night or perhaps in the preceding nights as the marine layer deepens, and then a slight chance of light rain mainly in the north on Sunday. Winds switch offshore early next week, bringing warmer, dryer air into the region.
