Fog has been observed overnight in the North Bay and East Bay Interior Valleys. High clouds streaming in from a dying cold front are adding complexity to the fog forecast both in terms of viewing it from space via satellite as well as seemingly not letting it get widespread like initially thought. Still, if you are driving this morning, slow down, use your low-beam headlights, and leave plenty of distance ahead of you. The aforementioned cold front will be the main feature today. Rain can be seen to the north on our neighbor Eureka's radar, but this is not expected to hold together down here. Instead, what we can expect is a pause in the warming trend, a return of onshore flow, and an extra colorful sunrise/sunset from the cloud shield. One more round of minor coastal flooding is expected during high astronomical tide this morning for bayshore locations along the San Francisco Bay, San Pablo Bay, and Monterey Bay. Hazardous beach conditions continue at Pacific Coast beaches, read more in the BEACHES section.

A warming trend commences Monday and peaks Wednesday as longwave upper-level ridging builds into place and sets up its axis over the region. Sensible weather wise, this will result in temperatures of 10 degrees above normal. Global ensemble clusters are in agreement that the aforementioned ridge will begin to get shoved east on Thursday by upper-level shortwave troughing that will skirt the region Friday into Saturday. This will relatively cool temperatures with no rain in the official forecast.

Hazardous beach conditions will continue through Monday at all Pacific Coast beaches.
