The episode as NWS HNX wrote it up.
A surge of upper level tropical moisture pushed into central California from the southeast during the morning of July 13 and continued for much of the day. At first the thunderstorms were mainly dry as the lower and middle levels remained dry, and lightning from these thunderstorms ignited several new wildfires across the area. As the middle levels became more moist during the late afternoon and evening the thunderstorms became more in the way of rain producers. There were some locations in Yosemite National Park and the Upper San Joaquin River Basin which picked up between a quarter and a half inch of rainfall, but lower elevations generally only picked up a trace to a few hundredths of and inch of rain. There were also several reports of hail with one cell in Yosemite National Park.
The San Joaquin Valley radar (KHNX), 159 km away, was scanning. The volume nearest the first event began at 23:00 UTC.
1 thunderstorm wind, 1 hail. Local standard time, as filed.
Media report of a 20 year old hiker slipping and falling off of cables while descending Half Dome during a thunderstorm which was producing heavy rainfall and gusty winds. The fall resulted in fatal injuries.
Video evidence of 1.00 inch diameter (quarter sized) hail posted on Facebook.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
