Amazing videos are surfacing from around Rapid City South Dakota following a large supercell thunderstorm outbreak yesterday – June 19, 2015.
The RADAR feed (seen below) shows the storm as it developed and progressed in a near direct line towards the RADAR station transmitter.
Literally making a direct path towards the tower, and becoming the most intense as it passed nearby the NWS office.
See video of the event here from a dedicated group of storm chasers who I watch weekly — I recommend you subscribe to their channel immediately :
Clearly the hailstones were very large. Measuring near 3+ inches in diameter.
