Another day of local chasing as a shortwave was moving out of the Rockies and upslope flow was forecast to initiate storms along the higher terrain that would roll off later in the afternoon and progress across Nebraska. Moisture was limited, however, and I debated even chasing this day so I would end up waiting until late afternoon before heading out.

June 6th was a bit of a marginal day, a weak surface low beneath a modest shortwave trough along with looped hodographs would create an atmosphere favorable for south-east moving supercells across Western and Central Nebraska. We had a nice introduction to June for severe weather across Nebraska with plenty of local opportunities for chases.

An overnight MCS across Oklahoma and it’s associated outflow combined with a frontal zone setup a potent environment across Western Nebraska and storms were expected to fire along the front later in the afternoon.

June 4th featured a stationary front draped across southern Nebraska stretching east of a lee trough in eastern Colorado as the remnants of an MCV drifted across eastern Kansas. This setup would bring dewpoints near 60°F into southern Nebraska bringing with it MLCAPE values around 2,000 J/kg. I was expecting a few supercells along the front west of Grand Island so decided after work to head west and check stuff out.

Originally I was debating driving towards the day 2 target and staying at a hotel overnight but decided to head home instead.
