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.
The NWS defines a watch as the risk of a hazardous weather or hydrologic event [increasing] significantly, but its occurrence, location, and/or timing is still uncertain and a warning as hazardous weather or hydrologic event [that] is occurring, is imminent, or has a very high probability of occurring [1].
