TUE 12 JUN 2018
We left Salina (KS) at midday and travelled a couple of hours southwestwards to Medicine Lodge (KS). A near-stationary cold front was located nearby, and would hopefully be intersected by an old outflow boundary somewhere in south central Kansas.

After a relaxed mid-afternoon lunch (as no storms had developed yet), we trundled west to Coldwater (KS) - and en-route observed a developing thunderstorm to our southwest.
We essentially followed this thunderstorm for the rest of the day - it split twice, with the right-mover becoming the dominant cell in both cases, and forcing us to nudge a little south towards Buffalo (OK). The supercell then really started to wrap up, with some amazing structure at times and multiple attempts at developing a wall cloud.

The storm was only moving at 5mph to the south, since it was anchored to a boundary, giving us plenty of time to park up and observe the storm. The slow motion of the storm, and the vast array of gridded dirt roads in this part of Oklahoma, meant for an enjoyable chase.
A new meso developed on the western flank of the original storm, and so begun multiple occasions of back building where the new cell to the west became the new dominant cell, and we continued to nudge west past Laverne (OK) towards Beaver (OK).
|From an initially lone supercell...|

Sadly, despite many attempts, not a single tornado was produced, and once the thunderstorms became outflow-dominant we ended the chase and headed to our hotel in Woodward (OK).
