March 13, 2021 - The National Weather Service Hanford Office reports a storm system will impact Central California Sunday into Monday resulting in widespread precipitation.The heaviest precipitation will fall primarily in the Sierra Nevada mountains and foothills, where a Winter Storm Watch is in effect for Sunday and Monday evening above 4000 feet.
Precipitation is also possible in the Southern San Joaquin Valley, with thunderstorms possible on Monday afternoon.
Area Forecast Discussion National Weather Service Hanford CA 151 PM PST Fri Mar 12 2021 .SYNOPSIS... Temperatures will rebound back to seasonal averages this weekend, and a brief period of dry weather is in store. A return of cooler than average temperatures, wet weather, and mountain snow are expected to impact the region by late Sunday into Monday. Otherwise, a warming trend will occur by midweek. .DISCUSSION... On Saturday and Sunday, expect seasonal, though milder, temperatures during the daytime. Dry weather will prevail, although some clouds could develop over the mountains on Saturday afternoon due to residual moisture. The potential for precipitation on Sunday night is increasing, as well as the possibility of snow reaching below the pass levels in the Kern County mountains and into the Sierra Nevada foothills. Snow levels could reach as low as 3,000 feet by early Monday morning in the Kern County mountains, including towards Tehachapi and the Grapevine. Snow levels may be around 2,500 feet elsewhere, including into the Sierra Nevada foothills from Tulare County northward. The probabilities for lower elevation snow in the Sierra Nevada and Kern County mountains, as well as gusty winds in the Kern County desert and through/below the mountain passes are increasing significantly for Sunday night and Monday, compared to this time yesterday. Gridded forecast guidance (i.e., National Blend of Models, or NBM) now shows about a 40 percent chance for advisory level (45 mph gusts or higher) portions of the Kern County desert and mountains on Monday. In addition, our guidance (NBM) is showing at least a 70 percent chance of snow levels falling below 4,000 feet over much of the mountains. So, we can at least expect a return of colder and wet weather by early next week. On Tuesday, cooler than average temperatures will continue, but a warming trend will likely commence once again as a ridge of high pressure passes over California. Daytime highs after midweek will likely warm considerably, or back to at least a few degrees above average. Highs in the valley and desert are projected to reach the lower 70s by Thursday.Source: NWS
