Area Forecast Discussion . Updated National Weather Service Hanford CA 415 PM PST Thu Dec 5 2019
Updated Air Quality Issues section
SYNOPSIS. A ridge of high pressure will warm and dry conditions through Friday. Fog will threaten the valley overnight. Afterward, another weather system will affect the district over the weekend. Winter weather will return as rain and snow will once again blanket the Central California Interior for much of the weekend.
DISCUSSION. Fog plagued parts of the San Joaquin Valley this morning. Otherwise mostly sunny with some lower clouds on the west side of the valley and lots of thin high clouds crossing central CA from an upstream system. Temperatures warmed above forecast highs due to a ridge aloft and southerly downslope flow off the transverse mountains. A tough fog forecast tonight due to increasing high clouds and a pick up in south wind ahead of the approaching trough. Think there may be a mix of fog and low ceilings after midnight and quick clearing by mid morning with increased mixing from a pick in south wind. Warm air advection ahead of system along with downslope flow off the Diablo and Tehachapi mountains should result in another day of mild temperatures. Winds could be gusty Friday afternoon and evening ahead of the approaching storm especially in the central valley and west side.
Models prog the system tapping into a plume of tropical moisture off Baja as it approaches California. Precipitation may start Friday evening towards Yosemite spreading southward across our area through the weekend. The higher precipitation amounts are expected towards the north sectors in Merced and Yosemite area decreasing towards Kern County. Snowfall amounts may range from 2 feet towards Tuolumne decreasing to 1 ft towards Sequoai Park. Near 3 feet of snowfall may be possible in the higher elevations of the sierra especially north of the Kings River. This system will be colder with snow accumulations down to 6kft.
An East Pacific Ridge of high pressure will build inland over much of the west coast for early next week, bringing warm and dry conditions across our area but potentially producing more episodes of San Joaquin Valley Tule fog.
AVIATION. MVFR conditions with local IFR visibility in parts of the San Joaquin Valley due to patchy fog 10z-17z Friday. Otherwise VFR conditions elsewhere in the next 24 hours.
AIR QUALITY ISSUES. None.
CERTAINTY. The level of certainty for days 1 and 2 is medium. The level of certainty for days 3 through 7 is high.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
