GRAINSFIELD, KS AND HOXIE, KS TORNADOES
My Wednesday evening chase strategy paid off well for Greg Breneman and me on Thursday, May 22. Sitting on the immediate cool-side of the stationary front just east of the (secondary/eastern?) dryline led to three tornadoes between Grainsfield and north of Hoxie, KS. Geez, I even told a UK documentary company the evening before that our starting point would be Grainsfield, KS, but they never met up with me!
Tornado 1:
Touchdown: ~1SW of Grainfield, KS (Approximate...we viewed touchdown from 1.5E of Grainfield)
Time: 2229z-2250z (confirmed for accuracy)
Type: Rope tornado (good contrast, nice video)
Movement: due north at about 30-35mph
Dissipation: Unknown...but it dissipated about 3 miles west of KS Highway 23 somewhere between Grainfield and Hoxie
Tornado number one was quite spectacular since we filmed almost the entire lifecyle of a "clean," good contrast rope tornado. I called WFO Goodland shortly after their issuance of a tornado warning for this storm to report a wall cloud a few miles SSW of Grainsfield, KS that had little or no discernable rotation. The tornado touched down about 5 minutes later! :-0 This rope passed about 2 miles to our west. Wet fields led to little or no dust for most of its lifecycle. It did develop a dust bubble near the end of its lifecycle. Flat terrain led to a good view of the contact point.
Tornado 2:
Touchdown: ~3-4W of Hoxie, KS (approximate...we were in downtown Hoxie when it touched down)
Time: 2303z-2317z (confirmed for accuracy)
Type: 1/4 mile wide multi-vortex truncated cone, then truncated cone, then tapered funnel, the rope dissipation
Movement: due north at about 30-35 mph
Dissipation: Unknown...but it dissipated about 4 miles west of KS Highway 23, somewhere north of Hoxie, KS
A classic occlusion process led to this tornado. The old meso was shed to the WSW of this new meso which dropped a truncated cone-multi vortex tornado west of Hoxie, KS. Contrast was good, so we stopped a few miles north of Hoxie and filmed this tornado as it passed about 3-4 miles to our west and then northwest. It transitioned to truncated cone with condensation fully to the ground, to tapered funnel, and finally roped out.
Tornado 3:
Touchdown: unknown
Time: unknown, but we saw it on the ground at 2323z (confirmed). It probably touched down around 2321z
Type: Tapered funnel as of 2323z
Movement: unknown, but probably north
Dissipation: Unknown. It became rainwrapped about 6-8 miles to our north and we couldn't keep up with it.
We didn't get much of a view of this tornado since we were falling behind and then it got rain wrapped. We saw it as a light gray tapered funnel about 6-8 miles to our north as viewed from the south on KS 23.
