Illinois, Indiana Moderate Special Weather Statement | Effective 08/19/2026 15:58

A brief funnel cloud was reported just prior to 5:20 PM CDT near Lostant in southwestern LaSalle County. Atmospheric conditions in the area will remain favorable for the development of funnel clouds until about sunset. These funnel clouds normally only protrude a few hundred feet downward from the parent cloud, rotate or spin like a top, and last a few minutes before dissipating. These funnel clouds rarely touch the ground and typically do not pose any sort of hazard. The atmospheric conditions that these funnel clouds develop in do not support strong, damaging tornadoes. However, on extremely rare occasions, these funnels can briefly touch the ground and produce very minimal, if any, damage. If threatening weather approaches, move indoors to a place of safety. The National Weather Service will continue to closely monitor the situation.
