Snapshot of the towering Wednesday afternoon cumulonimbus--one of a group which doused south suburban areas with lightning-peppered downpours
Walt Stagner of southwest suburban Yorkville, Illinois sends us this terrific shot of the towering cumulonimbi (thunderheads) responsible for thundery downpours which erupted across many of Chicago's south and southwest suburbs. Doppler radar scans put cloud tops at up to 42,000 ft.
Thanks Walt for the great shot!
