Marine Weather and Tide Forecast for Cloverdale, CA

DISCUSSION

Today Through Sunday

Current GOES-West satellite imagery shows diminishing fog and low clouds across the Valley this afternoon as an upper low continues it's path across southern California. The Dense Fog Advisory has been allowed to expire at 1 PM, although patchy areas of fog still persist across the Valley. Fog chances return tonight into tomorrow morning. Probabilities for visibilities 0.5 mile or less are 40 to 60% from the southern Sacramento Valley and southward, with the highest probabilities around the Sacramento metropolitan area. Remember to use low-beam headlights when driving through fog, exercise caution, and slow down.

As northerly winds increase this afternoon and into tonight, any fog present should quickly diminish. Strongest winds are expected Saturday along the western side of the Sacramento Valley (I-5 and westward) and in the mountains. Probabilities of gusts in these areas are 60-80%. Relative humidities will also trend lower over the weekend with these winds, especially over the mountains, foothills, and in the northern Sacramento Valley. No precipitation is expected with this weekend's system.

Next Week

As ridging builds back in early next week the potential for Valley low clouds/fog returns, though exact chances remain uncertain for the time being. Otherwise, cool and calm weather is expected for the start of the week. Mid to late next week a slight chance for unsettled weather returns as troughing attempts to move into the area. Ensembles show a range of solutions, though all of them are limited to minor impacts at most. Some solutions have dry weather through next week, while others show light rain and a dusting of high elevation snow. Check in with the forecast periodically for updates.
