The warm conditions in combination with outflow boundaries and a nearby cold front made for perfect conditions for severe weather. The storms that fired tried very hard to produce, but it was just not enough. The cell forming over Independence showed promise, even though the Jefferson County Kansas storm had more potential. It seemed we would have a better chance catching something out of the Independence storm, if it produced, but it turned into a disorganized blob by the time we got south of it in Raytown.
We then decided to head west on 70 towards Lawrence. Besti got hailed on by quarter sized hail right before the turnpike interchange. We decided to turn around and re-intercept the storm which had been the same cell that had tornado warnings attached to it over Oskaloosa Kansas earlier in the afternoon, but by this time it petered out. We stopped in Bonner Springs for a bathroom break and ice cream at the Dairy Queen, then we went home.

Storms that fired in Nebraska the night before, causing the outflow boundaries that interacted with warm moist air over NE Kansas and Western Missouri, creating the severe weather Saturday afternoon.
Storms started firing over Northeast and Central Kansas. They were descrete, then they started rotating, then they made the right turn heading south, though they were slow moving. The storm farthest to the west then showed good signs of rotation on radar, and was tornado warned soon after.
We chose to chase the storm over eastern Jackson county/ Independence.
We then went west towards Lawrence to catch the cell with a history of rotation/hail core.
The storms kept firing late into the evening, intensifying, dying, then reforming and going severe. The worst of the severe weather hit the northland of the metro area late in the evening. One cell showed signs of rotation over the west bottoms of Kansas City, then merged with a cell over Leavenworth and moved north about 23:30.
About the time the rotation couplet moved over our house at about 23:45, there was a brief severe burst of wind, probably lasting about 30 seconds. I had to go out and check to see if I could see anything, but with obscured vision due to trees and nighttime, I saw nothing. It was about this time that a lot of damage was occuring due to hail and high winds to the eastern part of Gladstone.
