Bay Area makes a welcome encore, casting aside the warm haze of yesterday's coast. According to a post from NWS Bay Area, the marine stratus, in a testament to the cyclical nature of our coastal climate, painted the overnight sky in hues of grey after the sun dipped below the western brim—we’re queued up for a gorgeously mild weekend.

But don't get too comfy with the sweater weather yet because the weather is setting the stage for a dramatic upturn. The National Weather Service San Francisco Bay Area has issued a statement predicting a hot, dry spell to take hold starting next week, with the marine layer bowing out to make room for that sizzling sunshine. Cooling temperatures brought by "a southerly surge of low clouds and fog" will pep up your weekend plans, but the ridge breakdown and a connecting trough to the north promises it’s just a prelude to the heat onslaught that's marching our way.
Stashing away those light layers might be prudent, as the "big story this week is the drastic warm-up arriving Monday," per the National Weather Service's overnight report. An enabling pattern will cast a ridge across the region, cranking the thermostat even at coastal enclaves like San Francisco and Santa Cruz, where temperatures could tease the 90-degree landmark by Tuesday afternoon. At the same time, inland dwellers might feel the mercury bursting past the century point.
As the cut-off low weakens and traipses inland, it allowed the East Pacific High to extend a ridge across the Bay Area. At the same time, a timid offshore wind pattern does little to temper the impending blaze of heat this forecast, which is certain to persist from Monday through Wednesday with an apex expected on Tuesday, also sparks a word of caution regarding fire weather concerns. Be mindful, Bay Area, for the dry conditions will turn live and dead fuels into a flammable state. Although emergency alerts like red flag warnings aren't forecasted as wind speeds should remain low, vigilance against fire threats is urged during these hot spells.
In nautical news, mariners must heed, and winds are picking up. The weekend sails smoothly under moderate northwesterly zephyrs, but come Sunday, things pick up steam, and the outer waters could even face near-gale force gusts. "Rough seas will persist over the outer waters through the end of the forecast period" with wave heights building between 8 to 13 feet, according to the National Weather Service.
