Issued at 857pm PDT Monday Mar 18 2024

Low stratus clouds are slowly progressing onshore along portions of the North Bay, SF Peninsula, and around the Monterey Bay. Expect clouds to fill in around the remainder of the coastal Bay Area and Central Coast overnight with patchy fog possible as well. This is well represented in the current forecast and more information about it is included in the discussion below. No changes necessary this evening.

.SHORT TERM... (This evening through Tuesday) Issued at 134pm PDT Monday Mar 18 2024

Satellite imagery is showing low clouds off of the coast from the San Francisco Peninsula and points northward early this afternoon. These clouds will spread back inland overnight and to the south into tomorrow morning. Overnight lows are forecast range from the mid 40s to lower 50s region-wide.

Once low clouds erode, tomorrow afternoon temperatures will warm into the upper 50s to mid 60s near the coast and upper 60s to mid 70s across the interior.

Long Term
(Tuesday night through Sunday) Issued at 329am PDT Monday Mar 18 2024

There's good global model agreement that a consolidation of a few lows will take shape over the eastern Pacific Tuesday night into Thursday. On Friday light to moderate rain will begin spreading across the forecast area as the newly formed eastern Pacific low gets nudged eastward. Wet weather is in store for late week and the weekend, with highest rain totals 1" to 1.5" mainly along the coast especially across the coastal hills and mountains. Relatively lesser amounts of rain will fall over inland locations, with the least amount of rain over the southern interior where a few hundredths to a tenth of an inch are forecast. As always, the forecast can change, especially if convection develops, this could boost local rainfall amounts. Stay tuned to the latest updates. If planning travel to or across the high mountain country check with your local NWS office(s) or favorite media outlets for forecast details, it'll be cold enough for snow, please plan accordingly if traveling.

Marine
(Tonight through next Saturday) Issued at 446pm PDT Monday Mar 18 2024

High pressure over the region will continue the pattern of fair and sunny weather through at least mid Thursday. Winds out of the northwest and light to moderate through at least Wednesday. Come late Thursday, chances of light rain begin initially over the northern waters and winds turn to become more westerly. Through the day Friday, rain begins to slowly move southward. Moderate NW swell gives way to a new longer period NW swell train late today.
