March 7, 2009 Partridge, KS
Departed Goodland, KS with an initial target near Pratt, KS near the triple point as a developing sfc low began to eject into south central Kansas. Weak convection emanating from SW KS began to intensify as it interacted with deep low level moisture and a subsequent more unstable air mass as it approached St. John, KS. Soon after, the storm began to intensify rapidly, taking on supercell characteristics as it neared Abbyville, KS. Observed a tornado fairly early on in the storm’s life cycle when it was just NW of Patridge. The entire formation occurred rapidly with an initial benign looking base but intensifying core. Soon after, a large chunk of scud developed and rapidly lifted beneath the updraft region with a dust bowl soon forming. The circulation then quickly tightened with rapid cloud base rotation above. There was not enough evidence from my perspective to determine if there were additional “tornadic” circulations or if these were resulting from the RFD surge. I lost the updraft region as it passed through Hutchinson and caught back up with it prior to it crossing I 135. Ended the day observing dime to nickel sized hail south of Lawrence.
