Bay Area residents can expect a typical start to their summer with the usual pattern of nighttime fog and inland clearing, which is expected to continue through the upcoming week. The National Weather Service San Francisco, CA, forecasts a gradual warming trend entering the new week, with inland regions seeing seasonal temperatures. At the same time, coastal areas stay slightly cooler due to persistent cloud coverage.

According to the Area Forecast Discussion issued by the National Weather Service, "Inland highs will reach the upper 70s to low 80s while coastal highs stay in the upper 50s to low 60s." Brief instances of coastal drizzle are also anticipated, primarily from Santa Cruz to the Big Sur coastline tonight, but little to no accumulation is expected.

The meteorologists at the National Weather Service have highlighted a continued warming trend through the week, with temperatures to build up into the mid-80s by Tuesday and Wednesday gradually. Despite this, no significant heat warnings are in place. However, those who are more sensitive to heat are advised to take the necessary precautions, especially outdoors.

Late in the week, a system bringing cooler temperatures could change the weather pattern. "By the weekend, inland highs will be in the upper 60s to mid 70s with coastal highs in the upper 50s to low 60s," the National Weather Service said. Rain is not likely to be a feature of this system, with any moisture associated with it projected to travel northward toward the Oregon border.

Aviation forecasts suggest varying conditions for regional airports. Local sites can expect IFR and MVFR ceilings to continue into the late morning hours, with VFR conditions returning in the afternoon. Meanwhile, gusty winds could periodically present challenges, especially for coastal regions.

Mariners are also advised to prepare for stronger northern winds, which are expected to pose hazardous conditions and steeper wind waves throughout the week. The National Weather Service has issued Gale Warnings and Small Craft Advisories across several coastal zones. All relevant updates and warnings can be found on the National Weather Service's website.
