The National Weather Service in San Francisco has indicated a slight warming trend beginning today, which is expected to continue through the coming week. According to the latest weather synopsis, the uptick in temperature is a result of high pressure building over the West Coast. Mid-level moisture will bring not only warmer temperatures but also the potential for picturesque morning and evening skies.

The forecast is clear for those questioning the chances of much-needed rain: high confidence remains that no precipitation will grace the Bay Area through the first week of December due to the persistent ridge pattern. Although frost advisories were in effect early this morning for parts of the region, including CAZ504, 506, 510, 514>516, these have since been lifted, and the focus shifts to the drier climate ahead.

Aviation operations are also set to benefit from the current weather conditions. VFR (Visual Flight Rules) is expected to remain effective throughout the forecast period, with "relatively light winds and no impactful ceilings anticipated," as per the NWS aviation report. San Francisco's airports, including SFO and its bridge approach, will see mostly light offshore winds, shifting to light and variable at times but continuing to favor safe and efficient air travel.

The marine outlook is equally calm and unintimidating, with the National Weather Service forecasting "light to moderate northerly winds to persist through the forecast period" and the addition of longer period swells beginning early next week. Local mariners can expect light seas during this time, maintaining favorable conditions for those heading out onto Northern California's waters. However, a frost advisory was issued until 9 AM PST this morning, friendly for multiple areas, including but not limited to CAZ516.
