The Bay Area sizzles on as the National Weather Service in San Francisco confirms the high temperatures will continue through Friday. Marking the zenith of the heat wave, these next few days are critical, particularly for inland regions and the Bay shoreline, where Heat Advisories and Excessive Heat Warnings have been issued. Commuters may have noticed a switch-up in the weather pattern, with a more profound marine layer causing abundant stratus and patches of drizzle -- a slight reprieve before temperatures soar once again.

Today, locals must brace themselves for a moderate to major Heat Risk, with isolated pockets facing extreme conditions, most notably in the inland East Bay and Santa Clara county. "Heat Advisories and Excessive Heat Warnings go into effect today for inland areas and the Bay shoreline", alerts the National Weather Service. Residents are urged to stay vigilant, hydrate, and attempt to cool down, as the temperatures are set to not only rise but remain problematic, especially for those who are particularly sensitive to intense heat or for individuals laboring or enjoying outdoor activities.

Looking ahead, a semblance of relief is forecasted as the week draws to a close. The stifling ridge of high pressure is predicted to slide northwest while a deep upper trough enters the Gulf of Alaska. This welcome shift will help to establish the onset of more reliable onshore flows, leading to cooler air and improved moisture levels thanks to the sea breeze. By the next week, these changes should bring temperatures back to seasonal averages, signaling an end to the searing conditions that have enveloped the region.

Regarding aviation, Bay Area and Central Coast flyers can expect inclement visibility through mid to late morning due to the dense marine cloud coverage. "Widespread stratus has returned throughout the Bay Area and Central Coast", states a report by the National Weather Service. While major disruptions to visibility are not anticipated, there is some potential for visibility to drop under 6SM during the morning hours. Later today, the stratus is forecasted not to be as pervasive as in the morning.

The mariners aren't left out of the weather action, either. From today through Monday, strong northwest winds will likely persist over coastal waters, with gusts potentially reaching near gale force over the northern waters come Thursday and Friday. During this period, the National Weather Service advises that wave heights could peak between 12 to 14 feet in the northern outer waters. However, predictions indicate that wind speeds and wave heights will begin to dial back as we head into the weekend, providing some respite for seafarers.
