 | About This Shoot | Date: 30 June 2012 | Location: Southwestern South Dakota from Enning to Elm Springs to Badlands Nat'l Park, SD | Shoot Type: Storm Chase | | Synopsis: This was a rather frustrating storm chase that culminated on a positive note. Jay Antle, Evan Bookbinder, and I were targeting along and just north of I-90 east of Rapid City. As storms initially struggled to develop, we became impatient and went after an ongoing storm to our north-northeast, northeast of White Owl, SD. As we reached the town of Enning after driving on unpaved roads, we learned that this storm was severely undercut, and the only way we could get in the proper position was to backtrack down to I-90. As this was happening, a hail storm developed to our south. We eventually got southeast of this storm along I-90 and got into a favorable viewing position when we got into the Badlands National Park. In the park, we photographed the storm which took on some marginal supercell characteristics. At sunset, we drove south of the park along Hwy 44 near Imlay, SD and photographed some marginal mammatus as we also documented some golfball size hail that had just fallen before we arrived. |

Sat, 30 Jun 2012 17:28:07 -0500 Fwd: 4:30 PM CDT Jun 30 Chase Update | Had an awesome early afternoon at a park in Spearfish, SD and have made
our way down east of Rapid City. After watching a nice storm go up over
the Black Hills, we have decided not to go after it since it appeared to
be rooted in the terrain and driven by orographics and very weak shear.
Meanwhile, hi-res radar imagery shows strong cyclonic flow just east of
RAP with a number of feeder convective rolls spiraling in toward areas
just east of the city. The Cu field continues to grow with several areas
of strongly agitated Cu east and northeast of Rapid City. The deep layer
shear is also much improved with eastern and northern extent. Unlike
yesterday, the upper winds are from the northwest, which may lead to
storms struggling to maintain buoyancy as their anvil shadow is cast
downstream along the expected storm motion. Additionally, storm spacing
may be an issue with the entire axis of instability primed to go, so
mergers and outflow dominance may take over with time. Still hoping we
can maintain some discrete nature for a while, and that scenario looks
quite promising given the initial low level flow fields. Should be a fun
show regardless with maybe our first evening lightning photography
attempt afterwards. - Bookbinder
