A lightning strike with legs? What gives? It is another example where two branches of the invisible step leader reach ground charge simultaneously, allowing return strokes to surge up through both. This storm occurred at 3 am on the morning of the infamous "Nuclear Cap" storm intercept bust. Although this thunderstorm formed early in the morning, the cap strengthened considerably during the day. This prevented more than a few small towering cumulus (TCu) on the dryline the following afternoon, when tornadic supercells were as sure as ever if storms would just develop. Instead, storm observers went home empty-handed -- except for this electrical display in the wee hours of the previous morning.
