A line of scattered showers remains over the far northern outer waters along with breezy northerly winds. Showers will exit the area overnight and winds will weaken. Light northwest winds prevail through the end of the week and continue to be the influence on the sea state at around 7 to 9 seconds, along with a weak southerly swell. Winds and gusts look to increase Wednesday afternoon and into the evening through the Golden Gate gap into the San Francisco Bay.

523pm PDT Tuesday July 27 2021
Light showers have pushed northward out of our forecast area this afternoon. Long range forecast is seasonably warm and dry through the rest of the work week. Slight cooling starts by Saturday as marine air pushes farther inland over the weekend.
as of 02:53pm PDT Tuesday...Current radar shows that the last of the light showers has now pushed north of Sonoma and Napa counties meaning that "Sprinkle Watch" is over for our CWA. We had several reports on social media of folks seeing rain drops in their neighborhoods across the Bay Area this morning into afternoon. Much of the precipitation was just trace amounts, but there were a few isolated spots that measured around 0.01-0.03".
The rest of this week puts us in a fairly stagnant synoptic pattern as a broad and large high pressure cell dominates much of the CONUS through Friday. With that high pressure stretching into the west coast, we'll see warm and dry weather in our region, particularly for our interior locations. Meanwhile, coastal locations will have more mild temperatures, but could still be a bit warmer than normal. The temperature range for coastal areas will be in the 60s and 70s this week while inland spots range in the 80s and 90s...could see a few triple digit marks this week in the hotter areas of our CWA, but nothing widespread. As stated in prior discussions, the inland spots will generally range about 5-10 degrees above normal. However, at this time, we are not at risk for this turning into a significant heat event. Folks in those 90-100 degree locations will still want to make sure they stay hydrated and avoid strenuous work during the heat of the day, though.
As we approach the weekend, an upper level low off the coast of Canada will have a trough extending southward off the CA coastline. On Saturday and Sunday, that low will nudge inland and weaken the large CONUS high. As this occurs, we'll start to cool into a more seasonable range as the marine layer will build back and usher in the cooler, moist marine air.
Have taken a look at long range models and there seems to be a hint of another round of monsoon moisture making it's way into CA again. The main difference is that the moisture will likely stay east of our forecast area and be more of an impact for the Sierra.
as of 02:33pm PDT Tuesday...Scattered showers remain over the northern outer waters, but are slowly moving northward out of the area. Drier conditions expected Tuesday evening. Northwest winds prevail and remain fairly weak yet continue to be the influence on the sea state at around 6 to 8 seconds along with a weak southerly swell. Winds and gusts look to increase Tuesday afternoon and into the evening through the Golden Gate gap into the San Francisco Bay. Locally generated steep wind waves may be hazardous for smaller vessels.
