Morning discussion from Anton:

"Can’t say I am as enthused about prospects today as I was earlier, and choosing a target might be a fool’s errand. An acceptable setup looks to be the US-34 corridor in NE Colorado, say from Akron over to Wray. What I do like is what we saw on our drive north yesterday: The Panhandle soils are saturated, and with abundant sunshine today moisture pumping into the boundary layer should be significant. The models are designed to recognize such things, but probably not to the degree we are presented with at the moment. This may give us a few hundred joules more CAPE than guidance depicts. If I didn't have the CAMs to sway me I would be aiming for Kit Carson."

Elevated Showers

After a long drive north from Texas, we pulled off the rural northeast Colorado highway to assess our prospects, and it wasn’t looking good. Only elevated showers materialized in the cool environment.
We took the opportunity to snag a team photo while parked though.

Sunset Gust Front

7:58 PM
We called the chase and grabbed a room in Sidney, NE. Storms erupted to the west by evening, but they were clearly elevated in the cool, capped environment, so we didn’t bother going after them. The MCS caught up with us in town by sunset. The colors on the gust front were exquisite, and we watched the show from the front of the hotel with IPAs and a cheeseless veggie pizza.

"Storm chasing is very, very hard work."

Conclusion

A solid bust for sure, but the after chase sunset gust front was still a spectacular show.
