Great example of radar sidelobing in Iowa today, where radar beam edge interacts with meso aloft & falsely shows it near ground! KDVN (BR on L/BV on R) appears to show 2 circulations, but right circ is in low BR area & false - left circ is with BR 'hook echo' & actual #tornado

@shamnadoes How do you know that it’s sidelobing instead of 2 strong tornadoes next to each other?
