July 18th, 2011 South Dakota Tornado
Last Updated on Saturday, 06 August 2011 20:57 Written by Roger Hill
July 18th would be my last chase day for the month. We started the day in Bismark, ND. By early afternoon a boundary would set up over northern South Dakota. A tornadic supercell formed along this boundary southwest of Reva and anchored itself there for about an hour. We quickly went west and south on the Enchanted Highway and caught up to it in time to watch a substantial tornado. This supercell was fairly HP, but gave us a nice show with a moderately visible cone tornado. As it roped out, a new core on the south side of the supercell, pushed the tornado east as it became pretty visible. Most of the duration of the 12-14 minute tornado, it was poorly contrasted. Fortunately it occured in a area that has little to no population. This storm was also highly electrified with numerous very close and intense cgs occuring.

| Intense supercell with clear slot and mostly rain wrapped tornado here. |
Zoomed in shot moments later as the stout cone comes into view! |

| Wider shot and you can still see the cone tornado here. |
Roping out, but still a decent elephant trunk tornado. |

| HP supercell, slowly weakening. | Storm is steadily dying here, but still photogenic. |
