Thirtysomething debuted Sept 29, 1987, on ABC and within a year had won an Emmy for best drama series and was on its way to becoming more than a show. It turned into such cultural phenomenon, the title made its way into the dictionary and, subsequently, into TV history.
The difference between a tornado watch and a tornado warning means the difference between taking action or taking precautions. A watch means that conditions are favorable for a tornado to occur. A warning means that a tornado has been seen or picked up by radar. A warning requires you to take shelter and brace for a potential tornado.
There are distinct guidelines for determining if a watch or a warning should be issued. For example, a severe thunderstorm watch is issued if conditions suggest that winds may reach 55-60 miles per hour (about 88-96 kilometers per hour) or higher, or may produce hail that is 0.75 inches (about 1.9 cm) in diameter or larger.
