A powerful trough moved from the west coast towards the central United States, and set the stage for a large severe weather outbreak. The event was forecast days in advance by the SPC, with a risk area outlined with the day 6 outlook. On the day of the event, the SPC upgraded the moderate risk they had in place the day before to a high risk for north Oklahoma, central Kansas, and south Nebraska. A strong surface low had formed and was positioned in northwest Kansas. The dryline extended from the surface low down into southwest Oklahoma, and a warm front was draped across much of the southern half of Nebraska. Given the impressive dynamics, with a 110+ knot jet streak nosing into the risk area, as well as a very strong low level jet, shear was not going to be an issue. 0-1 km SRH values wer
