June 15 Evening Thunderstom

Last night's thunderstorm in Salt Lake City may have caused and increase in ozone at several air quality monitoring stations. Thunderstorms can cause increased ozone because lightning creates NOx, a compound that is a precurosr pollutant that can create ozone. Also strong downdrafts from thunderstorms can transport stratospheric ozone down to the surface.
Circled in Red is the ozone increase during the time of the thunderstorm.
Radar at 23:05 Local time
Lots of CAPE that evening from the HRRR sounding (21:00 local time)
