Area Forecast Discussion National Weather Service Hanford CA 425 AM PST Sun Nov 17 2019 .SYNOPSIS... Dry weather will continue over the district through Tuesday. Above normal afternoon temperatures can be expected today and Monday. A cooling trend will occur for the remainder of the week with the possibility of wet weather from Tuesday night into Thursday night, especially over the mountains and desert. && .DISCUSSION... A ridge of high pressure is nosing inland across central CA while a weak upper low slips southward toward southern Baja. Some high clouds are spilling over the ridge but our skies are mostly clear and we can expect just some patchy fog in the San Joaquin Valley this morning with seasonably cool morning lows. Dry conditions will continue today and Monday with temperatures trending upward beneath the building ridge. By Monday, highs should reach around 10 degrees above climo. Tuesday will be the beginning of a significant change in conditions over our area as models show a developing trough dropping southeast from the Pacific Northwest region while the Baja low drifts northeast. The first effect will be slightly lower afternoon highs on Tuesday. By later Tuesday night we will have a chance for some precip in the desert and mountain areas as the trough slides south and develops an upper low near the central CA coast while the Baja low lifts toward the southwest US. Models are quite similar as they continue to swing the developing low pressure system into the southwest US Wednesday into Thursday. This will mean precipitation chances across our area Wednesday, especially over the mountain and desert areas, and lingering into Thursday evening over the mountain and desert zones. Latest total QPF guidance shows around 1 to 4 tenths of an inch in the desert and ranges from around 1/4 to 3/4 of an inch of liquid in the mountains. Amounts in the SJ Valley range from a trace near Merced County to as much as 2 to 3 tenths in the south and east. Snow level will be mostly around 7000 ft and above, falling as low as 5500-6000 ft by Thursday as the precip is winding down. Several inches of accumulating snow will be possible at the higher elevations Wednesday into Thursday. Temperatures will also be significantly lower with the incoming system, down to around 4-8 degrees below normal for Wednesday and Thursday. The end of the week and through next weekend will see a return to drier conditions behind the departing low pressure system, with temperatures gradually increasing to around seasonal averages. We can also expect to see more significant fog development in the Valley after the addition of some moisture from the passing system.Source: NWS
