December 16, 2019 - The National Weather Service reports a cooler air mass settling into central California will bring lower overnight minimum temperatures across the area.
Areas of frost can be expected over much of the San Joaquin Valley early Monday and Tuesday mornings as lows dip into the low and mid 30s.
Area Forecast Discussion National Weather Service Hanford CA 123 AM PST Mon Dec 16 2019 .SYNOPSIS... High pressure over Central California over the next two days will keep weather dry before another storm system impacts the region bringing light precip to the area. Gusty winds in Kern County will be the main weather impacts this work week on Tuesday. Dry quiet weather late in the work week before a more potent system impacts the forecast area this weekend. && .DISCUSSION... Cooler and drier airmass over the forecast area this morning will allow for cooler temperatures this morning with many areas in the San Joaquin Valley hitting mid to low 30`s. Areas of patchy frost may develop in the lowest elevations of the valley as a result. High pressure aloft moving into the region will allow for clear skies today and high temperatures are expected to reach into the mid 50`s. The ridge of high pressure will build over the CWA Monday and Tuesday, fostering a strong offshore gradient. This will allow for increasing winds in Kern County -- main the Fort Tejon/Tehachapi/Grapevine areas -- by late Monday/Tuesday morning throughout early Wednesday morning. Strong east to southeast winds will occur during this time frame, so we have issued a High Wind Watch from 09z Tuesday through 12z Wednesday. The next disturbance that is progged to impact our forecast area by Wednesday will have scant precip totals. QPF totals of on a few hundreths of an inch are forecast by current blended model guidance in both the Sierra Nevada and western portion of the SJV. Medium range models are in good agreement that a high pressure pattern will resume late in the work week over the forecast area. High temperatures are forecast to climb Thursday through Saturday in the San Joaquin Valley before the next storm system arrives. Currently, high temperatures in the low 60s and mid to upper 60s are forecast to occur for the north/central and southern portion of the valley accordingly by Saturday. Finally, Saturday night through Monday are progged to be the next active weather period for Central California. Models are in pretty good agreement of a trough of low pressure bringing an appreciable amount of precipitation across the forecast area. However, QPF totals are still somewhat unclear this far out. Details will become clearer in future forecast packages as the event draws nearer.Source: NWS
