| Brief Description: A F2 tornado produced maximum estimated wind speeds of 120 to 130 m.p.h. and caused extensive damage 4 miles west of Richland, in Kalamazoo county. The initial damage occurred approximately one third of a mile south of the intersection of C Avenue and 24th street, extending north for about a mile. Extensive tree damage occurred along the tornado's path, and there was structural damage to several homes. One home along the tornado's path was completely destroyed, while several others sustained significant roof and shingle damage. The home that was destroyed lost it's roof, which was carried roughly 75 yards north of the home, and it also lost most of it's interior and exterior walls. The tornado's path length was one mile long with a width of 150 yards. | |||||||||||

| Brief Description: EVENT NARRATIVE: Several trees and large branches were knocked down across North 28th Street near the tornado touchdown. The most extensive damage was located approximately two-miles northwest of Richland south of E C Avenue. The roof was torn off a ranch-style house and completely destroyed with pieces of truss carried one-half mile. Insulation was found over one-mile away from the tornado damaged home. The back deck of the home was destroyed with a large piece of the deck thrown approximately 100 yards. All trees were snapped or uprooted around the house with two uprooted trees carried 30-40 feet. Nearly 1.8 miles northwest of Richland, about 50% of trees were snapped or uprooted with numerous branches down along the tree line. EPISODE NARRATIVE: Thunderstorms developed and moved across Lake Michigan during the evening hours on June 19th. Several hours of intense rainfall occurred starting around 7:00 PM EST. The ground was already saturated from early morning thunderstorms that produced very heavy rainfall. In addition to the heavy rain, severe thunderstorms and tornadoes accompanied the thunderstorms. | |||||||||||

| Brief Description: On Wednesday 10/24/01 a surface low pressure system tracked rapidly northeast from the mid Mississippi Valley to northern Lake Michigan and deepened significantly. The accompanying cold front surged east from the Mississippi Valley during the afternoon to southeast Michigan and western Ohio in the evening. The deepening surface low was the result of a negatively tilted upper level trough approaching the Mississippi Valley. The air mass ahead of the cold front was quite unstable with lifted indices around -5C and surface dewpoints of 65-70F. Strong veering wind fields were over the area with 20-30kt S-SSE flow at the surface veering rapidly in the low levels to southwest at 45kts, then remaining unidirectional above with wind speeds increasing to 65kt at 20,000 ft. An area of Thunderstorms across Illinois in the early afternoon formed into a line as they moved into northwest Indiana. Two strong bow echoes developed over northwest and north central Indiana during the late afternoon and moved northeast at 50 MPH into southern Michigan. Numerous tornadoes occurred in the comma heads of the bow echoes. Isolated supercells ahead of the main squall line produced little severe weather except for a tornado that occurred over northwest Ohio in the evening when the squall line merged with a supercell. | |||||||||||
