Area Forecast Discussion National Weather Service Hanford CA 320 AM PDT Thu Mar 12 2020 .SYNOPSIS...An low pressure system will move slowly east toward the southern California coast today then move inland tonight. This system will spread wrap around moisture into the southern portion of our area and bring another day with afternoon and evening showers and thunderstorms to Kern County. This system will move east of the area on Friday with dry weather and a warming trend taking place. A colder storm system drop southward into the area Saturday night and Sunday bringing increased precipitation chances and cooler temperatures. && .DISCUSSION...Skies cleared out across much of our area during the evening. Some upslope clouds are banked up along the slopes of the mountains in Kern County; however, producing local mountain obscurations and visibility reduction. The southerly fetch of tropcial moisture is now situated to the east of our area, and as a result the precipitation has also moved to the east of our area. SREF indicating the low pressure system now situated near 30N/123W which was responsible for brining the increased moisture and instability to our area is expected to slowly track eastward toward the Socal coast today and move inland tonight. As the low moves east some wrap around moisture is expected to be pulled into the southern portion of our CWFA this afternoon and evening. With LI/s progged to be between -2 and 0 DEG C and CAPES between 200 and 600 J/KG this afternoon over Kern County have increased POPS and added mention of a slight chance of thunderstorms for the Kern County Mountains and Deserts as well as for the far south end of the San Joaquin Valley. North of Kern County, daytime temperatures are expected to rise well above seasonal normals as morning sunshine will be more abundant during the morning and early afternoon hours. The low is expected to move into the Desert Southwest on Friday giving way to a dry northwest flow over central CA which will push out the wrap around moisture over the southern portion of our area and provide for another day of above normal temepratures north of Kern County. WRF indicating a cold low pressure system approaching the PAC NW coast Friday night which will then take a southward turn on Saturday. The medium range models are trending a bit slower with the southward progression of this system over the weekend, but still advertise it to drop southward off the CA coast on Monday then move it slowly inland on Tuesday and Wednesday. Although the models have had difficulty handling the exact placement and timing of this feature, the models are consistent in advertising a blocky pattern early next week with a deep trough prevailing over the western CONUS coast. This will result in temperatures trending downward over the weekend and lowering to unseasonably cool readings by early next week. Precipitation chances will increase across the area by Saturday night and precipitation will become likely over the area on Sunday and Monday. Unsettled conditions will then prevail across our area through the middle of next week as the low moves slowly inland over central and southern CA.Source: NWS
