DISCUSSION: As we go back in time to July 23rd, 2010, we arrive at what a pretty remarkable day in South Dakota state weather history. This day marks the occurrence of one of the more historic severe weather events in recorded history. The interesting thing about this particular event is that it is not historic for the more apparent reasons which most people are probably thinking of at first instinct. When people think of notably historic severe weather events, the majority of people will think of severe weather events which produced tornadoes, intense lightning, and strong winds often times. However, during this particular severe weather event which occurred back on July 23rd, 2010, it was hail that took the headlines.
Not only was there hail which was quantifiable for the purposes of issuing severe thunderstorm warnings for this storm but one of the hailstones which was measured was found to be an incredible 8.0 inches in diameter, having a circumference of 18.625 inches, and a weight of 1.9375 lbs. What is even more incredible is the fact that in order for a thunderstorm to generate a hailstone of that size, there would need to be a core updraft speed of at least 160 to 180 MPH to support the generation of such a large hailstone prior to the updraft no longer being able to support the weight of the growing hailstone. Thus, this is without question one of the more impressive hail-producing thunderstorms in recorded United States weather history.
