May 31st report


Today there was a broad marginal to slight risk of severe thunderstorms from portions of the western High Plains east-southeastwards into eastern Kansas and portions of Missouri. A slow-moving frontal boundary was close-by as well as several outflow boundaries.

We decided to target the I-70 corridor to the west of Salina, and headed to Russell for lunch. We then spent several hours there, whilst a number of storms formed south-east of us, near and east of Newton, along an outflow boundary. We held firm, watching a confluence zone near and south-east of Goodland which had gradually deepening convective circulations along it. A couple of showers formed south-east of Colby and so we departed and headed west, past Hays, to WaKeeney. We waited there for a bit as the showers deepened, and became thunderstorms. We then dropped south.

We observed an organised thunderstorm north of Ransom, which exhibited supercell structure for a time, before it become somewhat messier. However, we did observed a brief wall cloud which appeared to be from an occluded low-level mesocyclone.

We dropped further south to Ness City, and then east, and then north to Hays, observing some great lightning.

It was a good chase after a long afternoon waiting for initiation in our target area.
