Area Forecast Discussion National Weather Service Hanford CA 435 AM PST Thu Jan 9 2020 .SYNOPSIS... A weak storm system will bring a chance of rain and mountain snow to the area today, followed by quiet conditions into the first part of the weekend. A series of disturbances will then return unsettled weather to the region for next week. && .DISCUSSION... The next weak shortwave system dropping south out of the northeast Pacific is aiming an area of rain and mountain snow toward central California. Radar trends and model forecasts suggest the precipitation will reach northern portions of our area by 6 AM, spreading southward during the day and exiting the region by tonight. Qpf with this system is somewhat limited and snow amounts in the Sierra zones are expected to be no more than a few inches. Snow levels will be low enough to possibly produce a few flurries or a light dusting down to pass level in the Kern County mountains but major impacts are not expected. Rainfall amounts in the lower terrain and San Joaquin Valley should range from a few hundredths or a 10th of an inch down south to around 1/4 inch in northern portions of the area. Winds accompanying the incoming system will gust around 40 to 50 mph through and below the mountain passes in Kern County and a wind advisory is in effect there through 7 PM this evening. Weak shortwave ridging behind the exiting system will bring dry weather for Friday with the likelihood of overnight and morning fog in the usual places. The next system is then progged to brush our area Saturday with a chance for mainly mountain precipitation. After a break on Sunday, another weak disturbance will approach or area Monday. Model solutions begin to diverge in the details for Monday through the middle of next week as a series of disturbances impact the western us. Certainty in timing and precipitation amounts is low but blended model guidance suggests a generally unsettled period with more significant rain and mountain snow accumulations. Forecast details will become more certain with additional model runs.Source: NWS
