Between 6:30 PM CDT and 9:30 PM CDT, 3 severe cells were
tracked across Southeast South Dakota. The first two (blue
and magenta) were multicells and each
remained severe for approximately one hour. The last cell (red),
which developed around 7:15, became supercellular and produced most of
the severe weather observed. This cell eventually evolved into a
bow echo.
Also shown are location of severe weather reports - A## denoting hail with size ## hundredths of an inch, G## wind gusts to ## mph, and TORN indicates a tornado. |
