Marine Weather and Tide Forecast for Rancho Calaveras, CA

DISCUSSION

...Today-Saturday...
The trough over the Great Basin will deepen today as ridging builds over the eastern Pacific and the Pacific Northwest. This will lead to continued gusty north to east winds through Saturday.
The strongest winds are expected today with gusts 20 to 35 mph, and higher gusts over the mountains. Winds will weaken this afternoon, mainly in the Valley, before increasing again on Saturday with the strongest gusts of the day expected over the mountains. NBM probabilities of wind gusts greater than 30 mph on Saturday sit around 60-90% on Saturday west of I-5 in the Sacramento Valley, with a 50-60% of gusts greater than 40 mph over the mountains.

Dry and increasingly warm weather is expected into Saturday as eastern Pacific ridging builds, with highs 10 to 20 degrees above normal. Valley highs on Saturday are forecast to be in the upper 70s to around 80. Humidity levels will be noticeably lower, due to the building ridge, warmer temperatures, and several days of northerly to easterly flow.

...Sunday-Thursday...
Dry and warm weather is expected through this period, with above- normal high temperatures peaking this weekend. Sunday afternoon high temperatures will climb into the 70s in the Valley and foothills this weekend, with 50s and low 70s in the mountains. NBM indicates a 30-60% chance of high temperatures greater than 80 degrees across the northern Sacramento Valley, including Redding.
Above normal temperatures continue into early next week, though a system passing to the north will briefly flatten the ridge with slight cooling noticeable Monday and Tuesday, then a bit warmer mid to late week.

AVIATION
VFR conditions are forecast to continue over the next 24 hours.
North to east winds gusting 20 to 30 kts will persist until roughly 03Z Saturday through the Valley. Gusty north to east winds will continue to remain elevated through the Delta and over the mountains through the overnight hours.
