plainfield tornado

The Plainfield Tornado occurred on August 28, 1990. Forming in a matter of hours from a HP (High-Precipitation) supercell, it was the strongest tornado to hit Illinois since The Palm Sunday Tornado Outbreak, which occurred at Lake Zurich and Oak Park. The day started relatively normal according to late August standards. However, temperatures and dewpoints were above normal. Temperatures soared into the low 90's as dewpoints approached 80. At around 1 P.M., the National Weather Service issued a Severe Thunderstorm Watch for northern Illinois until 8 P.M. In DeKalb County, a supercell thunderstorm spawned an F2 tornado near Oswego, Illinois. Strengthening to an F4, the tornado travelled through Will County, before moving into Plainfield, Illinois, around 3:45 P.M. The tornado then took aim at Crest Hill, Illinois, where it caused F3 or F4 damage and killed 29 people.
