Area Forecast Discussion National Weather Service Hanford CA 132 PM PDT Sat May 30 2020
SYNOPSIS. Low pressure will move northward along the coast today bringing a threat of showers and a thunderstorms to the northern half of the district. Another area of low pressure will develop off the CA coast next week for continued seasonal temperatures and a chance of showers in the Sierra.
DISCUSSION. Short term focus this afternoon will be the chance of showers and thunderstorms in the Sierra and SJV, primarily north of Fresno County. Current GOES17 mid-level water vapor imagery and 500 mb RAP analysis is indicating a vorticity max moving into the northern half of the district. In combination with decent instability, SBCAPES of ~500 J/kg, will help initiate showers and thunderstorms this afternoon. Storms will be capable of producing heavy rain as well as small hail. Snow can not be ruled out in the higher elevations above 10,000 feet toward the Yosemite area. With the continued synoptic cooling aloft, high temperatures this afternoon across the central California interior are very pleasant, with mostly upper 70s to low 80s.
From Sunday into Monday, the NAEFS and deterministic models are showing a trough setting up just offshore, keeping a cool onshore flow in place and a chance of showers in the Sierra on Monday. 500 mb heights do slightly increase during this period, and temperatures will trend back up to seasonal conditions by Monday.
From Tuesday through Thursday, deterministic models and ensembles show an area of low pressure setting up off shore. This will increase our chances of precipitation across the Sierra. Temperatures will stay near seasonal averages.
AVIATION. Mountain obscuration in showers and storms over the Sierra Nevada are possible through 03Z. Showers and thunderstorms are possible in Merced and Mariposa counties after 19Z Saturday through 03Z. Otherwise, VFR conditions will prevail across the interior of Central California through the next 24 hours.
AIR QUALITY ISSUES. None.
The level of certainty for days 1 and 2 is high. 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.

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.
