SYNOPSIS
Issued at 1227 PM PDT Thu May 16 2024

Quiet weather continues with a persistent marine layer through the weekend. Calm and cloudy mornings will transition to breezy and clear afternoons. A weak cold front will move through next week, bringing stronger westerly winds and cooler inland temperatures.

UPDATE
Issued at 855 PM PDT Thu May 16 2024

Stratus quo this evening across the Bay Area and Central Coast.
Profilers put the marine layer around 2000 feet and the Oakland sounding agrees with the depth around 2100 feet. A quick check of pressure gradients around the region shows the onshore gradient has weakened since yesterday, but regardless it's still over 3mb.
Latest satellite fog product shows the persistent onshore flow is allow the marine layer to make it's nightly march inland. Current forecast remains on track for tonight. As noted below, in addition to clouds patchy drizzle will once again be possible. Hi-res model guidance generates a few hundredths along the coast, which is usually a sign of coastal drizzle.

SHORT TERM
(This evening through Friday)
Issued at 1227 PM PDT Thu May 16 2024

Stratus is continuing to clear. SW flow is delaying the clearing in Santa Cruz, Marin, and Sonoma counties, but there should be a few hours of sunshine before the next round of clouds develop this evening. The marine layer is quite deep, with the Ft. Ord profiler showing marine air from the surface to roughly 2,200 ft. This is quite a bit deeper than models suggest, which has led to some issues with the forecast. Not only are the deeper clouds penetrating further inland than expected, some of the thicker cloud decks have been producing measurable drizzle and light rain in Monterey, Santa Cruz and Napa counties early this morning. The forecast was adjusted to show a 15% chance of rain and 0.01" QPF for these areas tomorrow, as there is no synoptic reason for the marine layer to compress very much.

LONG TERM
(Friday night through next Wednesday)
Issued at 1227 PM PDT Thu May 16 2024

The same pattern will continue through the weekend with cloudy mornings and clear afternoons. The jet stream will take a dip south next week, causing a transition to a troughing pattern early next week. This pattern looks to persist through the week and will bring a few weak cold fronts, cooler temperatures, and breezy NW winds. Coastal drizzle may become a bit more prominent at times as well. High temperatures will reamin in the 60s along the coast, but will cool to the 70s inland.
