We started today from Souix City, Iowa.
Looking at the NOAA High Resolution Rapid Refresh (HRRR) model, it indicated late afternoon supercell development in the south eastern portion of South Dakota so we based our target on this and monitored both this and the SPC throughout the day to adjust our focus.

We headed initially North then west on the I-90 toward Mitchell. Adjusting our final target as SPC issued their Mesoscale Discussion and watching for rapid convective development to our North West we headed up towards Wessington Springs.

We could see funnels dropping and tornadoes had already been reported. As we headed east toward Crow Lake, a large wedge dropped behind us.

We continued east on country roads and the odd farm track through the wind farm which was taking a few CG lightning strikes making for some exciting driving.

We finally got clear of the wedge and got through to the small town of Lane. As we stopped, an area of rapid rotation formed to our South and dropped a cone which quickly matured. As I looked, a rope tornado was forming over our heads and into fields a few hundred metres away; an unbelievable scene.

We continued East then North and finally withessed the developed cone which had become a stovepipe and finally roped out in front of us.

In total 3 distinct tornadoes today. All tornadoes seen were reported to the local National Weather Service Office in Souix Falls.
