A high-based wall cloud hovers like a refugee from Independence Day over I-80 in the Nebraska Panhandle. Like most wall clouds, this one was nontornadic—luckily for the trucker! Winds strong enough to blow vehicles off the road can occur around and under wall clouds, even if they never spin up a tornado. For that reason, it can be a matter of life and death to avoid going under wall clouds—or if you are a weather spotter, to monitor and report them. Alas, outflow soon would undercut and dissipate this supercell, a fate of many High Plains storms with weak surface inflow.
