Bay Area residents basking in warmer weather can expect the sunny glow to linger with temperatures possibly flirting with the 90s, the National Weather Service San Francisco suggest. The latest forecast discussion, issued at 4:45 AM PDT Thursday, April 18, 2024, suggests warm temperatures are set to continue into the weekend despite a momentary dip on Friday due to a weak trough sweeping through the area. "Warm temps persist into the weekend with a slight cool off Friday," the NWS Bay Area's discussion read.

For those fretting that their thermometers might be on the brink of hitting 90 degrees, the NWS Bay Area's X update today suggests buckling up for a heat treat, "For those who are concerned about us breaking into the 90s over the next few days: this is a very important video," they posted, indicating that the heatwave isn't unfounded.

The short-term outlook paints a picture of a slightly cooler coastline today, thanks to stronger onshore breezes, while the inland valleys stay toasty. "Look for highs ranging from the lower to mid 60s along the coast tho the upper 70s to around 80 in the warmer inland valleys," the synopsis in the official forecast discussion states. Coastal fog could make a brief guest appearance around Monterey Bay, presumably vanishing by mid-morning.

Heading into next week, things are expected to transition yet again. The NWS predicts a potential return of precipitation by mid to late week as a moisture-laden trough approaches, but they hedge their bets as confidence remains low. "While most areas should see plentiful sunshine outside of some higher clouds there is some suggestion that low clouds and fog may develop around the Monterey Bay," the NWS forecast discussion notes, though contradictory, detailing the vagaries of Bay Area weather. A mix of sun and clouds, drizzle, and fluctuating temps are all on the table as the pattern meanders like a dinner guest unsure when to leave.

The weekend marine forecast doesn't rock the boat too much, with light to moderate winds steering us into Saturday. But sailors and sea enthusiasts should brace for "breezy to gusty northerly winds arrive Saturday afternoon," the NWS warns. An additional note not to be overlooked: A moderate period northwest swell is set to join forces with a longer period southerly swell over the weekend, plotting a course for varied sea conditions.
