As the Bay Area braces for a significant increase in temperatures this weekend, residents can anticipate a stark shift from the cooler, breezy days to an inflamed swath of high heat, especially inland. According to the National Weather Service San Francisco CA, high temperatures on Friday and Saturday range from the 90s to the low 100s inland, to the low to mid 80s along the Bayshore, and the 60s to low 70s along the coast. This warming trend arrives on the heels of an upper-level trough weakening over the region.

As the week progressed, the marine layer expanded due to an upper-level trough, creating a cooling effect that will rapidly dissipate. The trough, while lingering, is expected to lose its grip, yielding to a much warmer atmosphere towards the weekend. "Thursday should be a little warmer across the region as the upper level trough begins to erode and fill in," says the Area Forecast Discussion of the National Weather Service. The result, a surge of warm conditions to the inland areas, is expected to rise a few degrees, and even more dramatically, by Friday.

In tandem with the escalating temperatures, aviation and marine operations will also face some changes. "Winds Stay moderate through the morning with another round of breezy winds start in the afternoon," reports the National Weather Service in their Aviation section. While the Monterey Bay Terminals will see MVFR/IFR conditions and light winds through late morning, clear skies should prevail once the winds increase and lingering clouds dissipate.

The marine outlook, extending over the weekend and into the following work week, anticipates that waters will confront elevated northwesterly winds. Mariners should remain alert as, "Northwest winds increase again late Wednesday afternoon across northern waters, remaining gusty through the weekend and into the next work week," states the National Weather Service Marine report. Swells are also predicted to peak at a formidable 10–12 feet towards the end of the weekend, challenging seafaring vessels along the coast.

Amid the soaring temperatures, the National Weather Service issues a critical reminder: "Never leave kids or pets in vehicles" With the scorching days ahead, safety and preparedness are key, as the Bay Area plunges from its seasonal norm into the throes of a summer sizzle.
