Look for a gradual warming trend this weekend with more robust warming across the interior early next week. A cooldown is then likely late next week and into the upcoming holiday weekend.
As of 08:47am PDT Saturday...What a difference 24 hours makes. The strong N-S (SFO-ACV) pressure gradient has relaxed --- barely -5mb this morning and it was -9mb yesterday. The weaker gradient has resulted in much weaker winds this morning. The weaker winds and mostly clear skies also resulted in cooler temperatures this morning. A few interior valley locations even dipped into the 30s. Most of the Bay Area and Central Coast are cloud free, but a finger of stratus developed near the mouth of the Salinas Valley and pushed inland to Greenfield. These clouds will linger through mid-morning. The forecast was updated to include the localized cloud cover.
Otherwise, today will be warmer than Friday with pleasant weather expected for outdoor activities.
As of 03:00am PDT Saturday...Mainly clear sky conditions prevail over the region this morning with temperatures in the 40s to lower 50s. These readings are a few to as much as 8 deg cooler compared to 24 hours ago given the cooler air mass aloft and generally light wind. That said, we continue to stronger winds with gusts of 30 to 45 mph in the higher peaks in the Mayacamas Mountains of Napa and Sonoma counties.
A gradual warming trend is anticipated across the interior this weekend as high pressure over the eastern Pacific inches toward the coast. This will bring interior temperatures back into the 80s, 70s for the bay shoreline, and 60s near the coast both this afternoon and again on Sunday. Meanwhile, may see a bit of a shallow marine layer develop late in the weekend with the return of patchy/scattered coastal stratus.
More robust warming is expected early next week as the ridge axis shifts inland while also strengthening. By Tuesday and Wednesday, look for the region's warmer interior locations to reach into the lower 90s while most other inland areas peak in the 80s each afternoon. With the possible return of stronger onshore flow and associated marine influences, coastal areas are likely to hold in the 60s, especially northwest facing locations. While overnight temperatures will also warm early in the upcoming week, they will cool enough overnight to limit overall Heat Risk across the interior.
The aforementioned ridge of high pressure will begin to weaken on Wednesday resulting in a slight cool-down. However, temperatures look to remain above climatological normal for mid/late May. More widespread cooling is likely Thursday and into the holiday weekend as a trough replaces the ridge aloft. Any precipitation with this system is likely to remain well north of the region with continued dry weather conditions over the Bay Area and Central Coast.
as of 10:37am PDT Saturday...Strong northwest winds with near gale force gusts in the northern outer waters will persist through the weekend, with widespread steep, hazardous seas. Winds near the immediate coastline are forecast to be generally lighter, but still strong near coastal jets. Prevailing wave heigheights over 10 feet at periods of 9 to 11 seconds through the weekend will keep hazardous seas, particularly for smaller vessels. Winds are expected to restrengthen early next week.
