Marine Weather and Tide Forecast for Oakdale, CA

DISCUSSION

Today through Saturday
Current GOES-West visible satellite imagery shows the fog and stratus from the Valley this morning has lifted and burned off, with abundant sunshine now being observed on this Thursday afternoon. The Dense Fog Advisory was cancelled early as visibilities improved across the region. Patchy dense fog will be possible tonight into Friday morning, however chances are very low for any widespread development.

The upper level pattern will feature high pressure over much of the western US, gradually weakening and shifting eastward as we head into the weekend. Above normal temperatures will prevail across interior NorCal, with highs in the 60s to 70s in the Valley and foothills, and 50s to 70s in the mountains. A weak trough may bring the potential for light showers over the mountains south of Interstate 80 on Friday but minimal accumulations or impacts are expected.

Sunday and onward
Confidence is increasing in a pattern change later this weekend into next week. As the upper level ridge breaks down and shifts eastward, ensemble guidance indicates that upper level troughing develops, bringing along the potential for showers, mountain snow, breezy winds and cooler temperatures Sunday through the middle of next week. The latest forecast has trended lower for precipitation and snow amounts, and only minor impacts are expected over this timeframe. The Climate Prediction Center 8 to 14 day outlook then favors below normal temperatures and above normal precipitation for the February 13th through 19th timeframe, indicating the potential for active weather to continue through at least the middle of February.

AVIATION
Improving conditions for sites within the Sacramento Valley by this afternoon and evening with sites at VFR conditions after 00z Fri, outside of MOD and SCK who will remain MVFR to VFR due to mist. Overnight, we expect visibilities to drop to IFR to LIFR conditions after 06z from the southern Sacramento Valley southward as low as quarter-mile with accompanying low clouds with continued VFR conditions northward and light winds.

STO WATCHES/WARNINGS/ADVISORIES
