Area Forecast Discussion National Weather Service Hanford CA 324 AM PST Wed Dec 11 2019
SYNOPSIS. A trough moving through the area may bring some light showers to the Sierra this morning. High pressure will build back over the area tonight through Thursday with dense fog possible across the San Joaquin Valley overnight. Another Pacific storm system is expected to bring more wet weather Friday night through the weekend, mainly over the mountains.
DISCUSSION. Areas of dense fog continue across portions of the San Joaquin Valley, mainly south of Madera due to a weak disturbance moving through. A Dense Fog Advisory for these areas has been extended until 10 AM this morning. The weak s/wv trough has produced some scattered showers but precipitation amounts have been very light with just a few hundredths of an inch at most, mainly over the Sierra. Regional radar imagery shows just a few showers continue across the San Joaquin Valley and over the Sierra Nevada. Do not expect much if anything more from these as high-res models show them diminishing through sunrise.
The trough will shift east today as the northeast quadrant of a broad high pressure ridge builds over central California. This will provide us with dry weather this afternoon through Friday morning. There will likely be more Tule fog across the SJ Valley the next couple of nights and additional Dense Fog Advisories may be needed.
While the storm track will remain over the Pacific Northwest and northern CA the next couple of days, it will begin to shift south on Friday as the upper ridge gives way to an approaching trough from the north. Precipitation is expected to be focused around Yosemite Friday night and then spread south down to Kern County on Saturday afternoon. Lingering upslope showers may continue into Sunday. QPF is up to a half inch liquid around Yosemite NP tapering to around a quarter inch for Sequoia & Kings Canyon NP and only a few hundredths to a tenth of an inch in Kern County. Snow levels will begin above 8000 feet in Yosemite NP on Friday night then lower to near 6000 feet Saturday with up to 6 inches of new snowfall. Little rainfall is expected over the SJ Valley with trace amounts to a few hundredths, mainly along the eastern side of the valley. Dry weather is forecast Sunday night through Tuesday as upper ridging builds in from the Pacific.
AVIATION. In the San Joaquin Valley, areas of IFR/LIFR in fog and low clouds through 18z Wednesday. In the Sierra Nevada and adjacent foothills, areas of mountain obscuring IFR in low clouds thru 18z Wed. Otherwise, VFR conditions expected across the central CA interior for the next 24 hours.
AIR QUALITY ISSUES. On Wednesday December 11 2019 . Fireplace/Wood Stove Burning Status is: No Burning Unless Registered in Fresno and Kern Counties. Further information is available at Valleyair.org

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
