What happened
The episode as NWS BUF wrote it up.
Scattered thunderstorms crossed the western southern tier during the evening hours. The thunderstorm winds downed tree limbs and power lines. Lightning struck a 5000 gallon crude oil storage tank. The tank exploded blowing out the bottom of it and hurling it into the air. HAZMAT crews were called out to clean up about 3000 gallons of crude oil which spilled. The torrential rains resulted in flash flooding which closed roads in the city of Jamestown.
The radar
The Buffalo radar (KBUF), 90 km away, was scanning. The volume nearest the first event began at 22:54 UTC.
