A closed low pressure system moved slowly eastward across southern California during the evening of June 6 and morning of June 7. Showers and thunderstorms developed over Kern, Kings and Tulare Counties during this time frame as the low moved through the area. Some of the thunderstorms produced brief heavy rainfall resulting in roadway flooding near Bakersfield and Delano.

NWS Hanford, CA wrote its last area forecast discussion before the first event at Jun 6, 12:31 PM PST, 8 hours 39 minutes earlier.
Area Forecast Discussion National Weather Service Hanford CA 131 PM PDT Tue Jun 6 2023 .SYNOPSIS... A couple of low pressure systems will impact Central California today through the weekend, resulting in a chance of showers and thunderstorms, mainly during the afternoons and early evenings. Temperatures will remain below average for this time of the year. && .DISCUSSION... Satellite loops show an upper low pressure system spinning over Point Conception today. Radar imagery shows precipitation along the central California coast, isolated thunderstorms over Ventura County, and a cluster of thunderstorms over Mono County. All the activity is rotating counterclockwise around the upper low center. Additional shower and thunderstorm activity is expected through the day and into tonight. Latest high resolution guidance favors Kern County for convection this evening and possibly north into Kings and Tulare Counties. In addition to dangerous lightning, storms will be capable of producing hail and strong gusty winds. The upper low will wobble slowly east the next couple of days to around Las Vegas on Thursday. Medium range models then shift the low northeast as an open wave on Friday as upstream energy digs south just off the coast. The result is another upper low setting up right around Point Conception again next weekend. There is a chance of precipitation each day with the higher chances over the mountains and mainly during the afternoons and evenings. Rainfall amounts will be highly variable due to the convective nature. 24-hr trends show temperatures across the San Joaquin Valley are running around 5 to 10 degrees lower than this time yesterday. Highs are forecast to top out in the upper 70s to lower 80s this afternoon; around 6 to 12 degrees below climatological averages for this time of the year. Little changes are expected Wednesday then around 5 degrees of warming on Thursday and a couple more on Friday. Temperatures will trend cooler again over the weekend as the next upper low arrives. Highs are forecast to be around 5-10 degrees below average this weekend. && .AVIATION... VFR conditions will prevail through at least the next 24 hours. MVFR or lower conditions are likely in and near any thunderstorm this afternoon and this evening. && .AIR QUALITY ISSUES... None. && .CERTAINTY... The level of certainty for days 1 and 2 is high. The level of certainty for days 3 through 7 is medium. Certainty levels include low...medium...and high.
