    The term is used to indicate the end of significant weather conditions previously indicated for a forecast period. The specific dimensions would depend on the weather forecast product you are look at. It is typically used in the TAF which would mean a 5 mile radius of the station for which the forecast is prepared. There is no specific hight dimension other than to specify the height of cloud bases within the limits of measurement capability (typically 25,000 ft)
