Good day all,
I was chasing out in Kansas on April 8, 2015, and was on the storms (and tornado) to the southwest and west of Medicine lodge, Kansas. The FULL log for this chase is also below at the link provided (also includes subsequent chase in Illinois on April 9)...

Below is the details on the Medicine Lodge, Kansas storm on April 8, 2015...
April 8, 6:00 PM - Interception and indirect penetration of an extremely severe and tornadic thunderstorm in Barber County, Kansas from west of Medicine Lodge, and north and east towards Nashville, Kansas near Highways 160 and 42. The storm was a classic (and cyclic) supercell thunderstorm. Two tornadoes were observed with this storm, one being a brief low contrast elephant trunk, and another one being a large tornado that lasted about 5 minutes. Fortunately these tornadoes occurred in open rural terrain. The storm had a striking visual appearance, with a striated updraft and multiple layers (like an upside down wedding cake). The storm also produced winds gusting near 50 MPH, and baseball sized hail. Hail to at least 2.5 inches, albeit melted, was observed west of Nashville, Kansas behind the storm as it was weakening. Heavy rains and frequent lightning (with some close hits) was also observed. Hail damage was observed near Nashville. Conditions causing the storms were a warm front / dryline interaction, surface heating, vertical wind shear, a low pressure system, and strong upper trough. Documentation was digital stills, HD video, and audio. A 2009 Ford Escape was used to chase the storms. A tornado watch was also valid for the area until 12 AM CDT the next day.
Below are pictures from the chase day (April 8, 2015)...
