GOES-16 1-min visible imagery provides a great view of the tornado storm along the North Dakota/Minnesota border on 11 July 2017. Overlaying 1-min NLDN lightning data provides the forecaster with a great display of trends in storm updrafts. Main updraft as seen in satellite imagery is shifted to the north and west of lightning core due to parallax effect. Also overlaid in the animation are NWS tornado (white) and severe thunderstorm (grey) warnings, as well as local storm reports (black).
