Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
high pressure building in from the north will lead to increasing northerly winds over the coastal waters this weekend and early next week. Gale force gusts are likely north of point reyes through at least Monday. Gale force conditions will begin to spread southward over the outer waters later Sunday. Expect hazardous conditions and steeper wind waves from these building winds throughout the week.

SYNOPSIS
Issued at 1255 PM PDT Sat May 18 2024

Typical summer-like pattern to persist through the weekend with gradual warming trend for the first half of the upcoming week.
Nighttime low clouds will spread inland and then retreat back to the coast by mid-to-late morning each day.

UPDATE
Issued at 842 PM PDT Sat May 18 2024

Satellite imagery shows stratus flowing inland from the coastal regions, while offshore, an offshore boundary just coming into the North Bay is eroding the stratus deck. The passage of a weak cold front earlier today will contribute to some clearing overnight and faster dispersal of the clouds Sunday morning. High resolution models are suggesting that even the Monterey-Salinas region, where the last two days have not seen any appreciable clearing of the clouds, could scatter out before sunrise tomorrow, but the fact that the observed satellite imagery is overperforming the model expectations is limiting confidence. High resolution models are also suggesting a chance for fog to develop in the North Bay tonight into early Sunday morning. At this time, not enough confidence in either scenario to change the forecast.

DialH

SHORT TERM
(This evening through Sunday)
Issued at 1255 PM PDT Sat May 18 2024

Slightly cooler temperatures are expected this afternoon ranging from the upper 50's to mid 60's at the coast to upper 60's to mid 70's across the interior (a few spots may reach into the upper 70's).
This is as a weak, dry frontal boundary moves across the region.
Tonight, expecting less in the way of drizzle however cannot be ruled out in typically favored locations. Temperatures overnight will range from the mid 40's to mid 50's.

In wake of today's frontal passage, expecting tomorrow to be slightly warmer across the interior as low clouds will likely be quicker to dissipate. Thus, tomorrow we should see more upper 70's inland while cooler conditions prevail near the coast (upper 50's to mid 60's).

LONG TERM
(Sunday night through next Friday)
Issued at 1255 PM PDT Sat May 18 2024

Sunday night, we are expecting a greater potential for coastal drizzle across the San Francisco Peninsula and coastal areas of the Central Coast. A gradual warming trend is expected from Monday into Wednesday as the region remains between a ridge out over the Pacific and troughing to the east-northeast. Therefore, expecting more of the interior to reach the lower 80's by Tuesday which is forecast to be the warmest day of the week. Meanwhile, low stratus will keep conditions cooler at the coast.

Toward the latter half of the week, look for deeper troughing to directly impact the region. This will bring temperatures back below seasonal averages by Friday and Saturday. Dry conditions, other than overnight coastal drizzle, are expected to prevail through the forecast period.

AVIATION

MARINE
