**Meteorological Briefing - Pleasanton, CA** **Current Conditions Analysis**

Pleasanton is currently experiencing classic early morning fog conditions with significantly reduced visibility at 1.5 miles and near-saturation humidity levels at 92%. The temperature of 47°F is within 3 degrees of the dew point at 44°F, creating ideal conditions for fog formation and persistence. Light easterly winds at 2 mph are insufficient to mix out the fog layer, while high pressure at 30.11 inHg indicates stable atmospheric conditions that are trapping moisture near the surface. These are typical radiation fog characteristics common to the inland valleys of the Bay Area during overnight and early morning hours.

The current weather pattern reflects a stable air mass with minimal wind flow, preventing natural fog dissipation. The combination of cloudy skies above the fog layer and light winds suggests this fog will be slow to clear. As solar heating increases through the morning, we should see gradual improvement, though the dense cloud cover may delay full clearing compared to typical fog events.

**Operational Impacts:**

Visibility restrictions will affect lot operations and test drives during morning hours. Customer traffic may be delayed as commuters experience slower travel times. Outdoor vehicle photography and detailing operations should be postponed until visibility improves. Moisture deposition on vehicle inventory is likely—surfaces will be damp and may require additional drying time before delivery preparation. Lot lighting should remain active longer than normal to maintain safe conditions for both staff and customers navigating the premises. Plan for fog clearance within 2-4 hours of sunrise, with conditions improving to partly cloudy skies thereafter.
