Intercepted a few supercells west of and near Scottsbluff, Nebraska. Upslope flow combined with decent instability set the stage for supercell development. A cell merger near Scottsbluff that occurred on an outflow boundary allowed a messy mesocyclone to spin up and produce a fairly brief tornado that caused some damage to buildings, power lines, trees and flipped cars near Melbeta. We got very close to the circulation.Very nice supercell in far western Nebraska. Another shot of the supercell, nicely structured. Cell merger occurred and a messy HP formed. The rotating meso is in the center with precip rotating around the south (left) side. Mostly rain wrapped tornado is quite visible here. It is very close to Melbeta. Pretty shelf cloud as the storm quickly became outflow dominant.
