Tornado And Severe Thunderstorm Watches

A Severe Thunderstorm Watch outlines an area where hail 3/4 inch diameter or larger hail and damaging thunderstorm winds are expected to occur during a three to six hour period. A Tornado Watch includes the large hail and damaging wind threats, as well as the possibility of multiple tornadoes. Typical watches cover about 25,000 square miles, or about half the size of Iowa.  In the below image from the Storm Prediction Center in Norman, Oklahoma, Severe Thunderstorm Watches are depicted in light blue and Tornado Watches are depicted in red.
