The Bay Area can expect a return to clear skies and dry weather, as the National Weather Service San Francisco anticipates a warming trend starting today and continuing through next week. According to the National Weather Service, while some patchy fog may linger this morning, conditions are set to clear up, leading to higher temperatures and dry and warm weather dominating the forecast period.
Due to high pressure within Wednesday's frontal passage, some low-level moisture has been causing fog and stratus along the coast and in the valleys. The North Bay seems to be the exception due to weak offshore winds. "The Monterey Bay region is actually reporting some areas of dense fog already," the National Weather Service San Francisco pointed out. Despite this, the ingress of drier air is expected to cause any fog to dissipate later in the morning, leaving the skies clear by the afternoon.
For aviation interests, the National Weather Service warned of variable conditions this morning, "It's VFR except for a mix of low clouds /MVFR/, patchy fog and dense fog /IFR-VLIFR/ from the East Bay to the north Central Coast." However, they anticipate VFR conditions, or "Visual Flight Rules" weather, by late morning, which will extend into the evening, though they do express low confidence that VFR will continue overnight and into Friday morning.
Nautical travelers aren't spared from advisories either. "Dense Fog Advisory until 10 AM PST this morning for Mry Bay," as the National Weather Service suggests for the marine sector. Alongside this, there are Small Craft Advisories in effect across several zones due to the sustained winds and potential for rough conditions at sea. The high-pressure system over the California offshore waters is expected to weaken towards the end of the week, maintaining dry conditions over the coastal waters and bays.
