Marine Weather and Tide Forecast for Coloma, CA

DISCUSSION

...Today - Sunday...
Stratus/Low clouds were more of the story this morning vs. fog dominating the forecast yesterday but still impacting much of the Central Valley and adjacent lower foothills. Out forecast remains on repeat with another round of low clouds/fog tonight into tomorrow morning with best chances Sacramento northward although fog is possible throughout all of the Valley.

Dry weather and seasonable temperatures are forecasted for the region, with upper 40s to 50s in the Valley and foothills, and 40s to 60s in the mountains for the daytime highs. Highs are trending several degrees cooler than initially forecasted due to the persistence of the fog/low clouds, keeping max temperatures from being fully actualized.

Next Week
High pressure builds across the region next week, allowing for a gradual warming trend with high temperatures warming to the 50s to near 70 (mainly for areas outside of stratus/fog development). Dry conditions will continue through next week.
Some ensembles are indicating a weak pattern change in mid December but there is a large amount of uncertainty as it is too far out in time.

AVIATION
