I couldn't let today's date go unnoticed...and figured it probably warranted a spot in this section.
Six years ago today, the record-breaking South Dakota tornado outbreak occurred. Over southeast and east-central parts of the state, multiple tornadic supercells formed and provided many chasers with unparalelled career-chases. One tornadic supercell produced multiple tornadoes (including the F4 Manchester event) affecting communities including Mitchell, Woonsocket, Manchester and De Smet, while another dropped anywhere around 14 tornadoes in the Centerville/Davis/Parker swath.
The date is also largely known for the success that Tim Samaras' group enjoyed with the Woonsocket-Manchester supercell, which managed to obtain two significant pressure-drop readings from the Manchester F4 tornado, the most notable of which displayed a 100mb drop at time of impact of tornado. This tornado formed south of Manchester, SD and directly affected the town at possibly it's peak intensity as a roughly 1/2-mile-wide wedge as it moved north. Manchester was never re-built. The tornado continued north, constricting into a barrel, cone, elephant's trunk and rope before dissipating.
The Centerville storm was a prolific tornado-maker which provided chasers with a rare chance to watch as it spawned 14 tornadoes over a relatively small area.
A search on Google can bring up several of the many great chase stories from this date. It humbles me to be able to say that I was able to witness a part of the Woonsocket-Manchester supercell, and it's a day that I will never forget. It's hard to believe it was six years ago.
