These photos came from Lincoln 21-H, Lynn Geissler, on the morning of September 17, 2002. The funnel appeared about 10 miles west of Davenport under a cool pool aloft leading to instability. Doppler weather radar showed very broad rotation in the area. Visible satellite showed one convective-looking element in the area. These photos were snapped around 1100-1115 am, and the funnel apparently dissipated between 1120 and 1125 am without touching down.
