The National Weather Service in San Francisco is alerting Bay Area residents to prepare for a series of weather shifts, starting with above-average temperatures today and transitioning to cooler, blustery conditions with a possibility of light rainfall and thunderstorms early next week. According to the National Weather Service, the current heat advisory will persist through 9 PM tonight for the Southern Salinas Valley, advising individuals to stay hydrated and to seek shade when possible to avoid heat illness. A thin marine layer was observed with a high-pressure system currently in place, but no record-breaking temperatures are expected away from the coast.
However, as an upper-level low develops off the Pacific Northwest coast, Sunday is set to experience a temperature drop of about 20 degrees compared to Saturday, creating strong onshore winds, with gusts hitting up to 40 mph. The service's forecast, issued at 158 AM PDT, forewarns that Monday will showcase weather that might make you dislike the start of the workweek even more, if you're not a fan of unsettled conditions, with temperatures diving 10 degrees below normal. Additionally, there's a 10 percent chance of thunderstorms on Tuesday alongside the risks of lightning, small hail, and bursts of heavy rain and wind.
Regarding temperature records, the Oakland Museum (OAMC1) could be skirting its daily minimum records set in the '70s and '90s early next week, with forecasted lows hovering around the low 50s, just a couple of degrees over historical minima. Weather heights will be slowly rebuilt throughout the week, meaning temperatures are expected to gradually inch back to seasonal averages, as a Rex Block takes shape over the Eastern Pacific Ocean, according to the National Weather Service.
Variable conditions are on the menu for the Bay's aviation and marine communities. VFR conditions will persist, but HAF can expect reduced visibility due to mist, a condition set to continue into Sunday. Meanwhile, mariners should be wary of heightened winds as small craft advisories are in place over the weekend and next week. Light rain might accompany a frontal passage sweeping across the region by Monday, though moderate seas are expected throughout the forecast period. In all, those taking to the skies or seas should stay vigilant and prepared for the changes that are coming fast and, for some, quite furiously.
