2006年6月24日，博尔德雹暴产生了非常强的降水，包括密度较低的圆盘状冰雹。这些直径4-5厘米的圆盘状冰雹是不寻常的，其中一些似乎是在高空积累的。大量非常细粒度的雪泥随着冰雹沿着留在了地面上。冰雹和大量的雪泥表明，云中大部分的水凝物增长是通过低密度或极低密度的成霜。与此相一致的是，雷达数据表明风暴的上升气流已经基本耗尽了液态水的含量。有证据表明，风暴中低密度水凝物的增长可能比通常所怀疑的要频繁得多。
The 24 June 2006 Boulder hailstorm produced very heavy precipitation including disklike hailstones that grew with low density. These disklike hailstones, 4–5 cm in diameter, are unusual, and some of them appear to have accumulated graupel while aloft. A large amount of very fine-grained slush was left on the ground along with the hail. The hail and the great amount of slush suggest that most of the hydrometeor growth in the cloud was by low- or very-low-density riming. Consistent with that, the radar data suggest that the storm updraft had substantially depleted liquid water content. There is evidence that low-density hydrometeor growth within storms may be considerably more frequent than is commonly suspected.
