1 June 2024 | NE Colorado-SW Nebraska | Supercell Structure

This was day 1 of a June storm chase trip for 2024. The target was far northeast Colorado to see if dryline storms would interact with an outflow boundary beneath 30-45 kts of shear.

As storms fired along the dryline, a smattering of them fired up just south of the Nebraska border. As slowly as things were moving, it was easy to just hang out and see what would eventually take over.

Eventually a cell to my west started to root near Sterling while its anvil provided a window to new storms blossoming further south near Otis.

By 2300Z, my western cell was getting rooted and looking more interesting with a curved feeder band. It eventually produced a beautiful lowering over hills and farmsteads on the horizon.

After that, it flattened out for a few minutes, then one more burst of activity in the base before it got choked off and put on a final, elevated structure display.
