Synopsis
Cloudy and cool conditions prevail through Thursday. High pressure starts to gradually build on Thursday starting a minor warming trend for the weekend and early next week.

As of 09:45pm PDT Tuesday...Marine layer of around 1500-1700 feet persists tonight as troughing pattern continues in association with low pressure sitting offshore from the Pacific Northwest. Sites above the influence of the marine layer (elevations above 2000 feet) will remain warmer and drier overnight. Nighttime satellite imagery shows narrow strips of stratus along the San Mateo county and Marin county coastlines in addition to more stratus around 30 miles offshore moving towards the coastline. Some light drizzle along the coast is possible early this morning.

No changes made this evening as forecast is on track.

As of 01:53pm PDT Tuesday...Temperatures are running a couple degrees cooler today than Monday. Coastal profilers are currently estimating the marine layer between 1700 and 1900 feet. Onshore flow is helping to keep temperatures cool, with only 70s and 80s in the forecast for Tuesday afternoon. While skies may momentarily be clear, after the sun sets, stratus clouds will once again move inland as overnight lows return to the 50s and 60s. The robust marine will help suppress fire concerns for most areas, but the highest peaks in the interior ranges will still be dry overnight.

A weak, dry front will pass over the Bay Area Wednesday, in association with an upper level trough passing. Cooler air behind the front will lead to cooler than seasonal norms on Wednesday and Thursday. As the trough approaches the coastline, it will perturb the marine layer enough that it may result in light drizzle in isolated spots along the immediate coastline, but not widespread enough to put it in the official forecast. But otherwise, the trough will harmlessly pass through and move northward toward Western Montana.

Behind the trough, high pressure will slowly grow and temperatures will gradually warm into the weekend. While the ridge will have more influence over the area, the trough in Montana will not be forgotten about. That is because on Thursday, it will make a turn and start drifting southward toward Denver on Friday. The result that relates to California's weather is that the broad scale wind pattern will turn to the North. While offshore winds in late September/early October are common in these parts, the large scale gradient between the low and our area is weak. Winds over the interior North Bay Mountains will increase from the North to around 25 mph. However, fuels responded well to the recent rains and the winds are not expected to be overly strong so there remains no fire concerns at this time.

Outside of that, the ridge sets over California to keep warmer quieter conditions over the area for a while. Long range models do not have another trough appearing in the Eastern Pacific until Thursday October 6th.

Marine
as of 9:34pm PDT Tuesday...Moderately strong and gusty northwest winds will prevail tonight and Wednesday along the coast south of Pigeon Point and over the waters south of Point Sur, with lighter northwest winds elsewhere. Then Wednesday evening through Thursday, northwest winds will increase across all the waters. Strongest gusts look to be along the coast south of Pigeon Point and south of Point Sur. Steep, hazardous seas also look to develop with wave heigheights potentially reaching 10 to 12 feet by Thursday evening. Winds and seas then look to diminish Friday through the weekend.
