As the Bay Area braces for today's scorching temperatures, with some areas expected to hit well into the triple digits, a Heat Advisory stresses the importance of cooling measures and hydration. According to the NWS Bay Area's forecast, this Tuesday welcomes the warmest day of the week. Still, relief is in sight as a cooling trend is anticipated to usher in near-normal temperatures for the upcoming weekend.

The inland areas of the South Bay, including San Jose and the Central Coast, are specifically facing the highest temperatures today, ranging from the mid-90s to an intense 110 degrees. In response, the National Weather Service has issued a clear Heat Advisory from 10 AM to 10 PM, highlighting a moderate to high risk of heat-related illnesses, especially for sensitive groups. They especially urge the public never to leave children or pets in parked cars and not to forget to limit outdoor activities during peak afternoon and evening hours.

An Area Forecast Discussion by the National Weather Service San Francisco, CA, clarifies that early this morning, the marine layer has compressed to a mere 400-500 feet, allowing these elevated temperatures to take hold. Despite its shallowness, the marine layer will continue to exert its cool influence along coastal regions, with temperatures remaining in the 60s to lower 70s.

Wednesday will start the anticipated cooldown, albeit inland areas are still expected to experience heat similar to Tuesday's peak. A subtle yet persistent decline is outlined for the following days, with a weakened ridge and an expanding marine layer contributing to a gradual return to normalcy by the end of the weekend. As mentioned in the forecast discussion, this trend towards cooler weather will remain consistent over the latter half of the week as the ridge shifts east and high pressure reduces. This is in harmony with the Tropical moisture passing through, allowing only cloudiness at mid-upper levels.

Navigators of the Bay waters are also contending with the weather's impact, with a sturdy northwest breeze and moderate to rough seas persisting due to the gradient between high pressure over the Eastern Pacific and lower pressure inland. However, this gradient is expected to relax later in the week, as per the Marine Forecast.
