EF0 tornado in De Kalb County, Illinois

Storm chasers documented a tornado touching down in a field south of Hinckley near Somonauk Road and Bastian Road. High resolution satellite imagery showed that this tornado first moved to the northeast mostly in open fields, but likely caused tree damage to properties just north of Bastian Road as it crossed into Kane County. The tornado then turned to the east and caused damage to multiple farm outbuildings, peeled shingles off of roofs, and caused tree damage before lifting as it tracked into Big Rock.

Following summer-like, record warmth, severe thunderstorms developed in the late afternoon of February 27th over northwest Illinois and spread east through the evening across the Chicago metro area.
