San Francisco denizens can anticipate a warm and dry conclusion to their weekend, according to the National Weather Service San Francisco CA. While the heat advisory expired on Saturday evening, the temperatures are still projected to hover around 5 degrees above the norm for the inland areas not graced by the marine layer. The cooling relief will not begin until Tuesday, as the city settles into a more autumnal pattern during the coming work week.
The NWS update reveals that a high-pressure system responsible for the recent warmer temperatures will soon start to break down. This shift allows for a trough from the E Pacific to gradually influence our local weather, subtly cooling the region down as we approach the latter half of the week. San Franciscans ought to enjoy today and Monday with some moderation, knowing that the coastal marine layer is ready to provide natural air conditioning in the following days.
Travelers and locals alike could face foggy commutes, with MVFR to LIFR CIGs reported at airports around the Bay, exclusive of Napa County's APC. However, there's "decreased confidence that APC will develop IFR CIGs for a prolonged period of time," NWS pointed out. For those near the coastline, like Monterey and Half Moon Bay, the decline in visibility should improve by midday. Aviation authorities caution about an early return of stratus this evening, with coastal sites likely to dip back into IFR-LIFR conditions overnight.
For boaters, a heads-up is in order: strong gusts are expected Sunday afternoon near Point Sur and the northern San Francisco Bay, prompting the issuance of Small Craft Advisories for these waters, as detailed by the NWS. After Monday, winds are expected to weaken, ushering in moderate breezes and seas that should last through the end of the week. Yet, mariners should continue to exercise caution when navigating the Bay Area's often unpredictable waterways.
Amid weather advisories and temperature patterns, the specter of wildfire remains a concern. "Warm and dry conditions will continue Sunday with active fire conditions continuing to be seen at the Pickett Fire on area webcams, especially above 1500ft," the NWS stated. Firefighters grappling with the blaze on the frontline can expect the existing conditions on Monday, with more favorable weather beginning on Tuesday and extending into the week. Agencies closely monitor the situation, ready to respond to the daily onshore winds that can complicate wildfire behavior overnight.
