Marine Weather and Tide Forecast for Strawberry, CA

DISCUSSION

Today-Mid-Week:

Warm and mainly dry weather continues with general upper level ridging. A weak disturbance brushes to the north on Monday, with just a slight chance of light rain over western Shasta and Tehama counties Monday afternoon. High temperatures will remain a few degrees above normal, with widespread low 70s to mid 70s this week.

Winds will generally be light and onshore. This will allow increasing low level moisture. Along with mostly clear skies, this will bring increasing potential for patchy fog for the Delta, the northern San Joaquin Valley, and the southern Sacramento Valley.
The latest probabilities for visibility less than 1/2 mile (fog)
are around 55-65% each morning.

As deep troughing over the Gulf of Alaska begins to drift southward around the middle of the week, another ridge builds in late Tuesday-Wednesday, allowing temperatures to warm further, peaking for the week around 8 degrees above normal, with some mid 70s as high in portions of the Valley. This pattern would also bring north winds in the Valley, and northeast to east wnds in the mountains and foothills. Gust in the Valley up to 20 mph, up to 25 to 35 mph over Sierra ridges and through northeast aligned canyons.

Late Next Week:

There continues to be considerable uncertainty late next week. Ensembles continue to indicate the potential for a shift toward an active weather pattern, with chances for heavy rain, heavy mountain snow and breezy winds. There is a general trend for a slower onset of this pattern, though. Cluster guidance still indicates significant uncertainty regarding the position and timing of the upcoming trough, with a range of possibilities evident. The speed of deep troughing over the Gulf of Alaska dropping toward the California coast remains uncertain. While precipitation could begins as early as Thursday, the latest trends suggest higher confidence for later Friday and even more so over the weekend. Be sure to stay up to date with the latest forecast information and check back for updates as we get closer.
