Another Nice Weekend Day
Expect another mild if not warm, sunny day on Sunday before the weather changes again. At the moment, high pressure is in control over the West Coast. A weak frontal system is sliding down the coast into Sunday morning, but it will only bring a few low clouds initially—more on that in a moment. After sunrise, we’ll experience another mostly clear day with above normal temperatures. That all comes to a crashing halt on Monday, however. A trough of low pressure will dig down to the south (to our west) and initiate deep southwesterly flow over the region. The digging trough will develop a surface cyclone along the frontal boundary (from Sunday) that will have stalled along the coast. This new low will drive the front inland on Monday, pushing a much cooler and moist air mass ashore. It’s looking more and more like we’ll see a round of accumulating drizzle bordering on light rain in the coastal mountains overnight Monday into Tuesday morning. The trough will linger on the coast through the end of the week with cool and potentially damp conditions continuing. More in the extended below…
AIR QUALITY: Good
Sunday: Mostly sunny with a few high clouds passing through and a few low clouds on the coast. Slightly warm with coastal highs in the 60s to low 70s and 70s to mid 80s inland. Breezy west-northwesterly winds late in the day.
Monday: Mostly cloudy on the coast with highs in the upper 50s to 60s and drizzle late in the day. Mostly sunny but cooler inland with gusty winds for the valleys. Highs in the upper 60s to low 80s. There is a slight chance for a shower or isolated thunderstorm in the far eastern mountains.
Extended: Tuesday morning is looking damp, especially in the coastal mountains with cool temperatures for the rest of the week. With the trough offshore, expect partly cloudy skies and a very slight chance of a shower. A better chance will come with a trailing system which will dig down the coast on Friday. Rain is seeming more likely with this one, though it doesn’t appear to be a high-impact system. Showers and cooler weather may linger into the weekend.
