Brief Description: The tornado first touched down along Highway 9 southwest of Good Hope snapping several trees. From there the tornado moved northeast across Town Fork Creek damaging several trees in a densely wooded area and snapping two large trees along a county road. Damage along this path was rated F0.

Brief Description: The tornado that went across southeast Adams County entered Brown County about 750 pm CDT southwest of Highway 24 and Timewell. Witnesses observed a multiple vortex tornado that damaged one home, two out-buildings, several machine sheds, and several grain bins. Approximately three miles northeast of Timewell the tornado damaged another farmstead and numerous trees. Six machine sheds were destroyed while a home sustained damage to the roof and the west and south walls. A number of large trees in the vicinity of the farmstead were also damaged. Five miles northwest of Mount Sterling, several witnesses observed a multiple vortex pattern with several smaller tornadoes rotating around a larger tornado. The width of the damage area (mainly trees) varied from 50 to as large as 300 yards. Numerous trees were snapped at the base of the tree and tossed northeastward. The damage intensity was estimated from F1 to the lower end of F2. The tornado continued to travel northeast crossing county road 1500 north (5 miles north-northwest of Mount Sterling). Several large trees were either snapped half-way or uprooted at this location. Damage path width ranged from 50 to as large as 100 yards while damage intensity was estimated at the lower end of F1. The tornado damage intensified a second time as the tornado moved across Illinois Highway 99, 7 miles north of Mount Sterling. One old farm home and a large barn were completely destroyed with debris tossed 1/3 mile to the east. A second farmstead 1/2 mile east experienced damage to several machine sheds, grain bins and a barn. The nearby home sustained little damage. Several large trees in the vicinity of the barn and machine sheds were uprooted or snapped near the base of the trunk. The width of the damage pattern over this area varied from 50 to 100 yards. Damage intensity ranged from F1 to lower end of F2. Many witnesses along the track of this tornado did not hear the classic "freight train" sound as heard in other cases. Rather they heard a "swishing" type sound. Additionally, many witnesses did not observe lightning or hear thunder as the tornado passed. A special thanks to Mr. Brian Gallaher, Chief of the Mount Sterling Fire Department for providing valuable information. | |||||||||||

Brief Description: EVENT NARRATIVE: The tornado touched down on the southern edge of Grandview. It moved through the center of town intensifying in rural areas as it approached the county line. In Grandview, several homes sustained severe damage. North of Grandview, about 1.5 miles, a farm house was completely destroyed. Other homes and trees along the path sustained damage. The tornado crossed the Louisa-Muscatine county line just south of Fruitland, IA. EPISODE NARRATIVE: A line of thunderstorms pivoted northeast into parts of southeast Iowa during the mid-morning hours of June 1st. Much of the area was just breaking out of a blanket of dense fog where visibilities dropped to less than a quarter mile. Dew point temperatures were in the middle 60s to around 70 degrees. The line of storms appeared to become more broken through the late morning hours, while the area from Iowa City to Waterloo appeared to stratify out into a large area of showers. Just before 12:00 pm CDT, rapid intensification of storm cells on the southeast end of the original line occurred as it moved into northern portions of Louisa County. A tornado touched down just south of Grandview, IA and moved northeast through Fruitland, IA and on to the southwest parts of Muscatine, IA. The tornado then lifted and as the storm cell continued to move northeast across Muscatine County. The super-cell re-intensified as it entered the southeast part of Cedar County just before 1 pm producing a brief tornado near Wilton, IA. The storm then moved across northwest parts of Scott County and Clinton County producing damaging wind gusts and large hail. The super-cell continued northeast into Jackson County producing a tornado near Bellevue around 2:30 pm, which moved across the Mississippi River into Jo Daviess County before lifting. The storm produced yet another tornado just south of Scales Mound, IL around 3:15 pm before moving into southwest Wisconsin and dissipating. During the early afternoon hours, additional storms strengthened on the south end of the original line of storms, which went on to produce wind damage and large hail as they moved through northwest Illinois through the late afternoon hours. | |||||||||||
