1948: A three block long section was devastated at the edge of Ionia, Iowa in Chickasaw County by an estimated F4 tornado. Six homes and a church were leveled, and nine other homes were severely damaged. Two deaths occurred in the collapse of the Huffman Implement Store. Overall, the tornado killed five people, injured 25, and caused $250,000 in damages. An F2 tornado touched down initially 5 miles northeast of Rochester. Barns, silos, windmills, and machinery were destroyed on four farms as this tornado tracked north.
1961: Severe weather struck the south suburbs of Chicago, IL. Joliet, IL reported an inch of hail with some hailstones the size of golf balls. Heavy rain from these storms also resulted in some flooding. A tornado struck the town of Peotone resulting in damage to nearly every building with damage also reported in Lorenzo and Wilton Center, IL. Damage was estimated at $9 million dollars with about 30,000 structures affected.
1999: On Friday, April 23, 1999, a horrific hailstorm moved southeast from Pennsylvania across Garrett County, Maryland and into the Eastern Panhandle of West Virginia. It had weakened some as it crossed Garrett County and the Allegany Front, but as it passed east of Keyser, West Virginia, hail began to increase in size once again. By the time it reached Capon Bridge in eastern Hampshire County, West Virginia, the size of the hail had grown from golf balls to baseballs. As it moved into Frederick County, VA, the hail storm continued to grow dropping golf ball size hail in a swath now reaching from the north of Winchester, south to Stephen City (about 10 miles). The intensity of the hail stripped and shredded leaves and bark from the newly budding trees. Hailstones grew to the size of Grapefruit (4 inches in diameter) just east of Winchester. The storm continued east through Clarke County, southern Loudoun, and northern Fauquier doing considerable damage to Middleburg, then across Fairfax County hitting Centreville, Chantilly, Fairfax, Burke, Springfield, and Lorton with golf ball to baseball size hail. It crossed the Potomac River and weakened just slightly. It moved across northern Charles, clipped southern Prince Georges and then into Calvert County with 1 inch to 1.5-inch diameter hail and onto the Chesapeake Bay continuing southeast to the ocean. The damage left behind was incredible. In Northern Virginia alone, it amounted to over $50 million dollars in losses to public and private properties. Some communities saw a third of the homes with siding and roof damage. Some required total replacement. Windows were broken, cars dented, and windshields smashed. Piles of shredded plant debris were left on the ground in the storm path. In about 6 hours of time, this one thunderstorm, moving at about 50 mph, did $75 million in damage. There have been other severe hail storms to hit this area before, but none to cause this much damage to property.
