Area Forecast Discussion National Weather Service Hanford CA 150 AM PST Mon Jan 20 2020
SYNOPSIS. Slight chance of precip in the Sierra Nevada today and tomorrow as a disturbance passes to our north. Dry weather through the rest of the work week as a ridge of high pressure builds, which will also be conducive to morning fog in the valley. Next chance of precip may occur later this weekend.
DISCUSSION. Latest GOES 17 satellite IR imagery reveals high clouds progressing over the district early this morning. Currently expecting morning lows to be around 39-42 degrees across most of the San Joaquin Valley. Some mixing may occur this morning ahead of the disturbance to our north, potentially preventing widespread fog across the Valley. Precipitation is possible in the Sierra Nevada this afternoon through tomorrow afternoon for Fresno County and northward, but model guidance is showing QPF totals to be scant as the main precip will be further north, associated with the upper low. Gradients in Kern County may tighten up by Tuesday afternoon through Wednesday morning to generate gusty winds in the Kern County mountain passes and Mojave Desert.
Wednesday, models are in agreement that a ridge of high pressure will begin to build over Central California. This will lead to a period of dry weather with morning bouts of fog likely across the Central Valley. Upper ridge will begin to weaken by the end of the work week as an upper trough approaches the west coast. Blended model guidance is showing a chance of precip for the forecast area by Sunday as the trough nears, however the location and timing of the trough this far out is somewhat unclear. Either way, it will likely break up the stagnant weather pattern that is forecast to occur for the latter portion of this work week. Details regarding this system will be ironed out with additional model guidance.
AVIATION. In the San Joaquin Valley, MVFR visibility due to mist through 18z Monday, with local IFR to LIFR conditions due to fog also through 18z Monday. Otherwise, VFR conditions are expected across the central CA interior for the next 24 hours.

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.
