Wall cloud near Valley, Nebraska, June 11, 2008


Today's photo is from near Valley, Nebraska. This is part of a line of storms that struck eastern Nebraska and western Iowa that day, killing four Boy Scouts just across the border, north of Omaha. It was a very tricky system to chase, as the tornadoes were embedded in a squall line (a long line of storm that usually produce a great deal of wind and rain, but rarely tornadoes) and were moving very rapidly to the northeast. An entire carload of storm chasers accidentally drove into a tornado a bit north of my position; they ended up on the Today Show.

This photo is looking to the southwest. I'd just finished shooting the approaching squall directly to the west when I looked almost directly up to my southwest and caught this wall cloud rapidly approaching my location. A wall cloud is a rotating cloud that lowers from a supercellular storm and is often a precursor to a tornado. I packed up right after this photo and booked it east to Omaha.
