Becoming Unsettled

We’ll start the work week with cool, blustery weather—and perhaps a shower or two. What a difference from last week! A deep trough of low pressure will persist over the western U.S. over the next few days. After the initial cold frontal passage late Sunday, an unstable and chilly air mass will settle in over the Central Coast, likely generating a few showers across the region. We’ll then remain in cool northwest flow through mid-week before the next system approaches.

AIR QUALITY: Good

Overnight: Partly to mostly cloudy with patchy drizzle possible. Occasionally breezy northwest winds. Lows in the upper 40s to low 50s on the coast and mid-40s to around 50ºF inland.

Monday: Partly cloudy with an isolated shower possible. Gusty northwesterly winds at times. Cooler, with highs in the upper 50s to mid-60s both on the coast and inland. Winds persist overnight.

Tuesday: Partly cloudy and continued cool. Breezy northwesterly onshore winds becoming windy up valleys late in the day. Highs in the upper 50s to low 60s on the coast and mainly 60s inland.

Extended: Cool conditions continue on Wednesday as we remain in northwest flow, however winds will be lighter. Clouds will increase late as a cold front moves in from the northwest. It should arrive early in the day on Thursday (Halloween). While the front will be in the process of dying out, it’s likely that we still could see some rain. Timing and intensity is still a bit murky. An unsettled weather pattern will continue into the weekend with the potential for additional, albeit light, rain chances Friday & Saturday. Latest trends are for high pressure to build in from the west after this, with warmer, dryer weather possible.
