Officials at EROS estimated the cost of damage at 2.9 million dollars. Nearby fields were stripped of vegetation and farmers fields were cratered by the falling chunks of ice. This high resolution imagery was provided by the EROS Data Center. The white streak running southwest to northeast is not hail. Surrounding live crops are red.
Green areas are high reflectivity caused by buildings, streets, etc. and blue areas are water.
This storm had plenty of advanced warning. This was a significant event for the immediate area just north of Sioux Falls but most of the storm reports occurred with just one storm as it tracked northeast from near Hartford into Pipestone and Rock counties during a 2 hour period. The most intense part of the storm occurred as it moved over the EROS data center. During this time the storm collided with an outflow boundary from another, weaker storm that had moved north across southwest Minnesota. Surface dewpoints were in the lower 70's with afternoon temperatures in the mid to upper 80s.
