Area Forecast Discussion National Weather Service Hanford CA 150 PM PDT Tue Mar 24 2020 .SYNOPSIS...Another storm system will bring more wet weather to the region through Thursday. Dry weather is expected Friday through the weekend, except for a slight chance of showers on Saturday for mainly the northern portions. Temperatures will be several degrees below normal through Friday then warming up to near normal this weekend. && .DISCUSSION...Isolated to scattered showers will redevelop by later this afternoon and this evening. Otherwise, expect mostly cloudy skies and cooler than average temperatures to continue over much of our region. Most of the snow in the Sierra Nevada for tonight into Wednesday morning is expected above 5,000 feet from Yosemite southward to Fresno County where a Winter Weather Advisory remains in effect, as several inches of snow is expected with local amounts up to a foot possible. Rain amounts tonight into Wednesday will be relatively light, though could become moderate to heavy for brief periods. Per latest satellite images, trough continues to dig off the coast of Northern California at this time. Precipitation is expected to gradually shift southward by Wednesday afternoon and continue into Thursday. Showers and thunderstorms are possible for mainly north of Kern County in the San Joaquin Valley and the west side hills. As the trough digs further southward and the upper- level low passes into our portion of Central California, colder air will arrive by Wednesday night, as snow levels could lower to around 3,000 feet and possibly down to around 2,000 feet by Thursday morning. Expect mainly a dusting up to around two inches for these elevations, though snow amounts are more likely to be at the higher end of the range at the 3,000 foot level. It appears lighter amounts of snow will occur over the Kern County mountains, though there is still the possibility of some accumulating snow on the passes, such as the Grapevine and Tehachapi Pass (or up to an inch). Otherwise, expect most of the snow (generally several inches, though up to near one foot in some spots) in the Sierra Nevada during late Wednesday afternoon into early Thursday morning to fall above 4,000 feet in the Fresno and Tulare County portions of the Sierra Nevada for Wednesday afternoon into early Thursday morning where a Winter Weather Advisory will also be in effect. Rainfall amounts for Thursday will be generally light to moderate. A drier pattern is in store by Friday, but the morning may be quite chilly. Even Thursday morning will be much cooler than average, as lows are forecast to fall into the mid to upper 30s in the Central Valley on both mornings. It appears Friday morning will be slightly cooler, as skies will be clear. A drier period with a warming trend is expected this weekend into early next week, with the exception of a weak upper-level low passing over Northern California with an associated shortwave trough passing over Central California on Saturday afternoon and evening. Thus, have introduced some slight chance POPs for Merced County and eastward into the Sierra Nevada for this period. The shortwave may provide enough lift for showers in the Sierra as far south as Tulare County. More noticeable warming is in store for Sunday and afterward, and temperatures will return to seasonal averages to perhaps a few degrees above as high pressure ridging sets up. However, at this time, how warm temperatures reach remains to be seen, as the models show considerable differences in terms of strength of the ridging.Source: NWS
