April 5, 2019 - The National Weather Service Hanford Office reports a weak storm system will impact Central California today.
In the San Joaquin Valley, measurable rainfall should be fairly light and mainly confined to areas from Fresno County northward.
Snow levels will be around 7,000 feet. Portions of Yosemite National Park above 7,000 feet could pick up one to three inches of new snow.
Area Forecast Discussion National Weather Service San Joaquin Valley - Hanford CA 218 AM PDT Fri Apr 5 2019 .SYNOPSIS...A weak weather system will move across the area today and this evening. The storm track will shift northward this weekend as high pressure builds to the south of the region. && .DISCUSSION...Satellite imagery shows one vorticity center moving southeast towards the Mexican border and the next larger weather system moving quickly towards the California coast from 130W. This feature is progged to arrive this afternoon and move quickly east during the late afternoon and evening. Overnight, ridging is progged by models to quickly build into the coast and this will shunt most of the following system well to the north of the Central California Interior. Given this, the forecast has trended much drier than previous thought. Models build heights over the forecast area Sunday and Monday and then bring the next system into Northern California on Monday night and then into the forecast area on Tuesday. This low pressure system looks to be a quick hitter as it ejects into the Rockies Tuesday night. Beyond mid week, forecast models are in fairly good agreement in bringing a low pressure system into California on Thursday with the GFS being much deeper with the low than the ECMWF. Confidence is low that the low will track to this projected position. Given this, the GFS solution would certainly be very interesting for some rather active weather. Will take a wait and see approach at this time and see if future models solution agree.
