Yesterday, meteorologists, and anyone else watching weather radar in southern Illinois, southwestern Indiana, and western Kentucky, noticed an unusual formation drifting through the area. Although evidence remains limited, this was likely a burst of chaff released from a U.S. military aircraft, but there is still no clear explanation as to why the plane released the radar-reflecting countermeasures in this particular area.
At around 3:00 PM Central Time on Dec. 10, 2018, weathermen at local news stations in the area, as well as a National Weather Service (NWS) in Paducah, Kentucky, began tracking the radar “blob” as it dramatically expanded in length and began to move southward. Closer to 2:00 AM Central Time on Dec. 11, 2018, Wayne Hart, the Chief Meteorologist at ABC-affiliate WEHT in Evansville, Indiana, took to Twitter to offer the first real information about the radar reflective plume.
