2006年4月13日至14日冰雹造成的财产损失导致中西部财产损失总计18.22亿美元，远远超过2001年4月冰雹事件创下的15亿美元的历史新高。2006年4月的巨大损失主要是由于多次强风暴和频繁的大冰雹袭击主要大都市地区。4月13日发展起来的一个高度不稳定的气团导致了几个超级单体风暴，然后在30小时的时间里，它们在爱荷华州、伊利诺伊州、印第安纳州和威斯康星州的部分地区产生了大范围的冰雹。这次风暴事件和最近的重大冰雹损失发生在几个主要冰雹形成后，然后移动了数百公里。1950-2006年全国十大亏损事件显示出显著的时间增长，其中1992-2006年期间损失最多。增长的原因可能是非常不稳定的大气条件越来越频繁地导致更大、更持久的风暴，和/或城市社会大大扩大，变得越来越容易受到冰雹的影响。
Property losses due to hailstorms on April 13–14, 2006, resulted in Midwestern property losses that totaled $1.822 billion, an amount considerably more than the previous record high of $1.5 billion set by an April 2001 hail event. The huge April 2006 loss was largely due to multiple severe storms with frequent large hail hitting major metropolitan areas. A highly unstable air mass that developed on April 13 led to several supercell storms and they then produced large hailswaths across portions of Iowa, Illinois, Indiana, and Wisconsin during a 30-h period. This storm event and prior recent major hail losses occurred when several major hailstorms developed and then traveled for hundreds of kilometers. The nation’s top ten loss events during 1950–2006 reveal a notable temporal increase with most losses in the 1992–2006 period. Causes for the increases could be an increasing frequency of very unstable atmospheric conditions leading to bigger, longer lasting storms, and/or a greatly expanded urban society that has become increasingly vulnerable to hailstorms.
