Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Expect winds to gradually increase this afternoon and evening. Winds will then pick up further on Monday as a disturbance moves down from the pacific northwest into northern california. NEar gale force gusts may be possible over the northern waters by Tuesday morning. Elevated winds will persist through mid week. These winds will produce steep wind waves creating hazardous seas conditions, particularly for smaller vessels. Moderate northwest swell through the period along with a lighter longer period southerly swell.

Area Forecast Discussion National Weather Service Sacramento CA 246 AM PDT Sun Apr 18 2021
SYNOPSIS. Dry and warm weather through Monday. Temperatures will rise to the upper 80s to low 90s for Valley communities. Despite the warm air temperatures, area waterways will continue to run cold. Cooler weather possible by middle of next week, with the chance of some mountain showers.
DISCUSSION. High pressure will strengthen over the region today leading to another hot and dry day for interior NorCal. Temperatures will soar into the upper 80s for most Valley locations with some of the warmer spots reaching the lower 90s. The foothills and mountains will be warm as well as temperatures range from the 50s to the mid 80s.
For Monday, little change is expected in the forecast as high pressure will still be the dominate feature. We may see a brief uptick in north winds for portions of the northern Sacramento Valley with winds weakening by the evening. Near the Delta, winds are forecast to increase late in the day in and should persist through at least the evening hours as well.
A pattern shift starts late Monday into Tuesday as an area of low pressure moves into the region. This will bring cooler air into the region and may even lead to mountain showers and thunderstorms. Currently, guidance continues to favor a slight chance for storms over the southern Cascades and down to Plumas County. We'll continue to keep an eye on this as storms may need to be added to the higher elevation of the Sierra.
Similar conditions are forecast for Wednesday, but showers look to be confined along the Sierra.
EXTENDED DISCUSSION (Thursday THROUGH Sunday).
Ensemble guidance shifts trough into the Desert Southwest Thursday and Friday with drier and warmer conditions returning as ridge builds back overhead. Extended ensembles indicate possible unsettled pattern heading into next weekend, but will we will see how this evolves over the next few days.
AVIATION.
VFR conditions next 24 hours. Surface wind gusts under 12 kts.
STO WATCHES/WARNINGS/ADVISORIES. None.
