Hotel location:  Chadron, NE

Intercept location:  Last Chance, CO

Two supercells were intercepted.  The first was non-tornadic but was sampled well by the mobile mesonet.

Second cell formed south.  A tornado was observed for 8 minutes, but data collection was hampered by lack of roads.  A second tornado occurred shortly after for 5 minutes.  Dual-Doppler data was collected.  The Unmanned Aerial System was successfully flown through the rear-flank gust front and the rear-flank downdraft.  Six pre-storm and 15 in-storm balloons were launched.
