The episode as NWS HNX wrote it up.
An upper level low pressure system moved inland over southern California on April 29. This system wrapped moisture northward into central California which produced scattered showers and thunderstorms mostly over Kern County. Rainfall amounts were generally light with most locations picking up less than a tenth of an inch. One thunderstorm did produce local roadway flooding in the Kern County Deserts. In addition, this system produced some strong wind gusts in the Tehachapi and Lake Isabella areas; and a few low impact indicator sites measured wind gusts around 60 mph during the evening of April 29 and again during the evening of April 30 as the low slowly moved east of our area.

NWS Hanford, CA wrote its last area forecast discussion before the first event at Apr 29, 12:47 PM PST, 53 minutes earlier.
Area Forecast Discussion National Weather Service San Joaquin Valley - Hanford CA 147 PM PDT Mon Apr 29 2019 .SYNOPSIS... Widely separated showers and isolated thunderstorms are possible in the Kern County mountains and desert, as well as in the Southern Sierra Nevada this afternoon into early tonight. A weak atmospheric disturbance may be responsible for isolated showers around Yosemite National Park Tuesday afternoon. All other areas will remain dry through at least Friday night. && .DISCUSSION... An upper-level area of low pressure over Southern California will open into a trough of low pressure as it progresses northeastward into and through the Desert Southwest tonight. The latest high resolution convective computer models indicate that the greatest potential for convection this afternoon and this evening will be in the Kern County desert. Gusty, west to northwest winds will develop in portions of the Kern County mountains and desert this evening, where a Wind Advisory is in effect from 6 PM PDT this evening until 2 AM PDT early Tuesday morning. A trough of low pressure aloft over the Pacific Northwest will move southeastward into Nevada Tuesday. This atmospheric impulse may be responsible for isolated showers around Yosemite National Park Tuesday afternoon. Gusty, westerly winds may develop once again in portions of the Kern County mountains and desert Tuesday evening. Another Wind Advisory may be required in those areas Tuesday evening into early Wednesday morning. A short wave ridge of high pressure will be located along 130W longitude Tuesday night. This ridge of high pressure will weaken as it approaches the Golden State Wednesday and Wednesday night. A Rex Block pattern will develop over the Eastern Pacific by Thursday. This usually marks the start in a downward trend in forecast confidence, as is the case here. There is considerable difference between the most reliable long range computer model output. The GFS computer model indicates that an upper-level area of low pressure will approach the coast of the Golden State Saturday, before progressing eastward across Central California Saturday night and Sunday. Meanwhile, the European computer model depicts this same area of low pressure aloft stalling near the coast of Northern California Saturday night, then moving parallel to the coastline Sunday into early next week. A blend of this model guidance was used, with a trend towards climatology. && .AVIATION... VFR conditions will prevail at MCE, MER, FAT, VIS, and BFL through at least the next 24 hours. Widely separated showers and isolated thunderstorms are expected in the Kern County mountains and desert until about 03z. Widely separated showers are possible in the Southern Sierra Nevada until around 07z. && .AIR QUALITY ISSUES... None. && .CERTAINTY... The level of certainty for days 1 and 2 is medium. The level of certainty for days 3 through 7 is low. Certainty levels include low, medium, and high.
