The main way tornadoes are detected is through Doppler radar. Doppler radar works by shooting invisible lasers at storms to detect for reflectance from things such as rain or hail. This is why you can visibly see storms on radar. However, they can’t detect tornadoes which are pillars of wind. Instead, they identify velocity couplets and hooks in the radar to indicate where a tornado should be. This works well for large tornadoes. However, these indicators may not necessarily appear for smaller tornadoes. During a cold front, a line of strong storms may produce QLCS tornadoes. These small tornadoes often go undetected by radar and can cause destruction to unsuspecting towns.
