BELOW IS RADAR IMAGERY FROM THE FIRST TORNADO AT 436 PM CDT. THE LEFT 
IMAGE REPRESENTS RADAR REFLECTIVITY AND THE RIGHT IMAGE REPRESENTS STORM
RELATIVE MOTION. THE REFLECTIVITY IMAGE INDICATES EVIDENCE OF A HOOK
ECHO (IN THE CYAN CIRCLE) WHICH IS A COMMON RADAR FEATURE IN TORNADIC
SUPERCELLS. STRONG ROTATION IS EVIDENT IN THE STORM RELATIVE MOTION
IMAGE ON THE RIGHT. THE GREEN COLORS REPRESENT VELOCITIES TOWARD THE
RADAR (LOCATED TO THE NORTHEAST OF THE STORM AT THIS TIME) AND THE RED
COLORS REPRESENT VELOCITIES AWAY FROM THE RADAR. THIS IMPLIES A
COUNTER-CLOCKWISE (CYCLONIC) CIRCULATION. THIS ROTATIONAL SIGNATURE CAN
ALSO BE SEEN IN SEVERAL SUCCESSIVE RADAR IMAGES FOR OTHER TORNADOES DURING
THIS EVENT.
