New UPDATE

SYNOPSIS
Issued at 1206 PM PDT Fri Apr 19 2024

A bit cooler across the board today with cloud cover in addition to a deeper marine influence. Continued cloudiness to start the weekend and a dry stretch going into next week. Potential drizzle/light rain chances mid-to-late next week.

UPDATE
Issued at 824 PM PDT Fri Apr 19 2024

It's a relatively quiet evening across the area with low stratus already onshore across portions of the North Bay and along the Big Sur coast. Given the relatively deep/moist marine layer expect stratus to expand to encompass much of the region late tonight into Saturday morning before clouds retreat to the coast by afternoon. Some orographically enhanced drizzle is possible tonight along the coast as well. This is all represented in the going forecast which is in good shape. Therefore no update is needed for this evening.

SHORT TERM
(This evening through Saturday)
Issued at 1206 PM PDT Fri Apr 19 2024

Well defined marine layer up to about 2,000 feet remains in place this afternoon per Fort Ord profiler. Expecting this to remain in place through into Saturday as the responsible upper low moves through and the onshore flow increases through tomorrow. Though the deep marine layer remains locked in through Saturday, the associated cloud cover will mix out during the afternoon, much like today, and give way to a rather pleasant afternoon. Locations right along the coast may see more persistent cloud cover lasting later in the day, however. Otherwise, expect northwest winds to increase Saturday afternoon, becoming breezy up to 25-35 mph along the coast and nearby coastal hills.

LONG TERM
(Saturday night through next Thursday)
Issued at 1206 PM PDT Fri Apr 19 2024

To end the weekend and start next week, ridging takes over the pattern once again with afternoon highs increasing by a couple of degrees for Sunday and Monday. Tuesday brings the next big change in the weather as the well-advertised upper low moves into the region. The most notable changes that will be noticed Tuesday are cooler temps and increased cloud cover. Really not much change to the forecast beyond that through the rest of the week. Certainty regarding rainfall remains about the same with still only about 25 out of 100 members advertise anything measurable. Again, the most likely scenario as of now will be drizzle in the hills and coastal areas with perhaps some pockets of sprinkles here and there.

AVIATION
(00Z TAFS)
Issued at 421 PM PDT Fri Apr 19 2024

VFR with moderate onshore winds. Stratus is expected to make a return tonight lowering flight categories to MVFR/IFR late tonight into Saturday morning for most terminals, except KSFO, KSJC, and KLVK where models show VFR expected to prevail through the TAF period. Low to moderate confidence on ceiling heights and timing for KSTS and KOAK, as some models show a brief hour or two of low CIGs near 13-15Z. VFR will return for all terminals near 17Z. Winds will diminish overnight but will become moderate to breezy again Saturday afternoon, especially near the coastal gaps and passes.

Vicinity of SFO...VFR through the TAF period, but models show MVFR stratus filling in near the terminal overnight. Will continue to monitor if any updates to the TAFs are needed. Breezy NW/W winds will start to diminish late tonight but will rebuild to breezy/strong by Saturday afternoon.

SFO Approach Bridge...Similar to SFO.

Monterey Bay Terminals...VFR with moderate onshore winds that are expected to diminish overnight. Stratus will return late tonight and lower to MVFR, but models suggest ceilings will get down to IFR.
With the models disagreement, low to moderate confidence that IFR will occur overnight into early Saturday morning. Will continue to monitor.

MARINE
(Tonight through next Wednesday)
Issued at 421 PM PDT Fri Apr 19 2024

Light to moderate breezes continue through the remainder of Friday before northwesterly winds increase to become strong and gusty Saturday evening. Swell builds into Sunday out of the northwest as gusty conditions continue but looks to diminish towards the middle part of the next week. Light southerly swell continues to move through the waters this weekend and through the next work week.
