June 25th had a lot going for it. Dewpoints in the 70s, an old outflow boundary, high CAPE and convergence would get storms exploding in the afternoon hours. We targeted a pair of severe storms west of O’Neill, NE and watched them intensify and move south. However the western most storm quickly died when it moved over the boundary and the second one also met the same fate. Meanwhile towards Norfolk a supercell became tornado warned and produced a brief tornado. I always watch trends in surface observations and satellite and noticed the boundary sharpening up and angling towards the northwest to the west of us. Moisture was rapidly increasing with dewpoints in Thedford, NE rising from the low 60s into the low 70s with strong easterly winds. Soon, a storm formed along the boundary northwest of Mullin and anchored for awhile. It steadily intensified as we blasted west. By the time we got to Thedford, the storm was strongly severe and we could see an impressive mammatus field under the anvil. As we continued westward to get a better view, the storm formed a strong couplet and a hook. Structure was starting to become visible as we approached Mullin. We continued west and soon were greeted with a magnificent sculpted supercell and a rapidly growing tornado! The tornado grew to an impressive cone, then wedge as it moved south towards the small town of Whitman. We stopped about 3 miles from it as it was getting ready to cross the road and continue southward where we had no south roads! Frustrating! The sight of both the supercell with large tornado under was the best I’d seen in 2024!! Just an amazing scene! We had to back track to Mullen and drop south so we could catch up to the supercell again. We would not see the updraft again in the daylight. As it approached North Platte, it weakened and eventually died. An absolute phenomenal day! Unfortunately the tornado hit a couple of houses near Whitman and caused significant damage and 1 injury. I shudder to think what could have happened if it hit the town directly!
