Area Forecast Discussion National Weather Service Hanford CA 408 PM PST Wed Dec 11 2019

SYNOPSIS. A moist flow may bring some light precipitation over the high sierra tonight. Otherwise high pressure will provide dry weather with dense fog possible across the San Joaquin Valley. Another Pacific storm system is expected to bring more wet weather Friday night through the weekend, mainly over the mountains.

DISCUSSION. Fog and stratus clouds was slow to clear in the SJ Valley today due to a lot of mid and upper level cloud cover. Temperatures in the central valley remained cooler than forecasted due to the low stratus clouds. The higher resolutions models indicate some light precipitation mainly over the higher elevations of the sierra tonight. Warm advection along a moist westerly flow will combine with disturbance pushing through central CA tonight. Rain potential will be mainly over the high sierra. Fog will continue to threaten the valley but should be less widespread due to the extensive upper level clouds and disturbance pushing through tonight. Think fog potential will continue through Friday morning before the next weather system. 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. Snow levels should lower late Saturday and Sunday as a colder disturbance moves through. Lingering upslope showers may continue into Sunday. QPF is around 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 to 10 inches 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 Thursday. In the Sierra Nevada and adjacent foothills, areas of mountain obscuring IFR in low clouds thru 20z thu. Otherwise, VFR conditions expected across the central CA interior for the next 24 hours.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
