Exactly what process I went through, except I didn't slowly work my way northward. In the narrative I used for this scenario, I was still sitting in North Platte when, at 18Z, the atmospheric information I needed miraculously appeared. After virtually digesting it I chose 1845Z as the departure time from KLBF to KVTN.
Given this time designation, I would have been just too late to see any of the tornadoes west of Wanblee. However, in real life I very well could have determined it wasn't going to work out this far south (KLBF) by, say, 1630Z, instead of 1845Z, because of the ability to get data in a continuous fashion. I would have been over 2 hours ahead of the chase case curve, and would be in position to easily get on this supercell from the beginning.
Well if this were real, hopefully we would be enjoying a steak dinner after bagging a couple of tornadoes. I would like to see what the tornadoes near Wannblee looked like.
