Trentham Stormchasers 2009 USA Roadtrip

Stormchase 24th May 2009: Lusk district, Wyoming

Report: Clyve Herbert

Today was to prove a busy storm day...after the Wheatland storm weakened, we drove east to Lingle, WY. A better convective field appeared near the southeast WY/NE panhandle border. From Lingle, we headed north to Lusk (again) following a series of potent multicells. It was getting late and the storms were starting to weakly organise.

A large multicell between Lingle and Lusk collapsed and sent out a reasonable gust front. Pretty soon, storms were developing ahead of the outflow boundary near Lusk. The storms appeared to be generating in the midlevels, however what happened just east of Lusk surprised us....where a strong pulse ingested the outflow gustfront into its rotating base. We watched the rotation for about 5 minutes before the cell collapsed, sending out another outflow guster on its northwest flank.

Spot the landspout?! We were surprised to notice a weak landspout on the inflow on a storm between Lingle and Lusk - lasted about 5 minutes
