Area Forecast Discussion National Weather Service Hanford CA 327 AM PST Tue Dec 10 2019
SYNOPSIS. A trough will move through the Central California Interior by Wednesday morning which may bring a few showers to the Southern Sierra tonight. Ridge then builds back into the area into Friday. A weak disturbance may bring some light showers over the Sierra late Friday into Saturday.
DISCUSSION. Complicated weather pattern this morning as areas of dense fog has developed across the SJV. A Dense fog advisory is in effect until 1100 AM PST. High clouds are moving overhead in association with a front off the CA coast that is forecast to move across the region tonight.
We are thinking that the fog will lift later this morning to a stratus deck that will lock in as warm air overrides the trapped cold air near the surface. Once the trough moves through later tonight, we are forecasting areas of drizzle to develop across the SJV . mainly north of Kern county. We have put in slight chance of showers in the Sierra tonight as the front pushes through. The NAM12 was advertising some light QPF mainly across the YNP area.
So . if the stratus deck does not materialize, then we probably wont see the drizzle and skies will be cloudy with high clouds over the area. It is a very difficult forecast with so many things happening at multiple layers in the troposphere. Confidence is very low with overcast conditions for today and drizzle for this evening. We have seen this pattern before play out this way and believe that this a possible solution. There will be some mixing as the front moves through by Wednesday morning . so clearing is expected in the SJV. However there will be some clouds banked up along the west facing slopes of the Sierra in a post frontal environment. Little change in temperatures through Friday . maybe a degree or two increase as the ridge tries to build Thursday behind the trough tonight.
A stronger trough is forecast to impact the region on Friday afternoon through Saturday evening. The models are in decent agreement that a cold front will push through the region bringing some rain and high elevation snow. Right now the QPF does not look that impressive as the upper ridge will try to hold in place and weaken the front. This event is still several days out and confidence is only medium at this point.
AVIATION. IFR/LIFR in fog and low ceilings in the Southern San Joaquin Valley through 19Z Today. MVFR in haze and ceilings through 06z in the SJV. Mountain obscuration in showers and clouds from 06z through 12z Wed. Areas of drizzle after 06z in the SJV mainly north of BFL. Otherwise, VFR conditions expected in the higher elevations of the Sierra and Kern County mountains and Desert.
AIR QUALITY ISSUES. None.
The level of certainty for days 1 and 2 is low. The level of certainty for days 3 through 7 is medium.
Certainty levels include low . medium . and high. Please visit www.weather.gov/hnx/certainty.html for additional information an/or to provide feedback.
HNX WATCHES/WARNINGS/ADVISORIES. Dense Fog Advisory until 11 AM PST this morning for CAZ180>189.

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.
