It is a series of meteorological forecast products. Most of the products base on a numeric weather model from NOAA/NCEP, called GFS, and aim on short-term (up to 16 days) weather forecast service for special purpose, for example, astronomical activities, or meteorological condition assessment. 7Timer! was first introduced in mid 2005 and has been revised for better fitting of public service operation in mid 2008. It's first designed as a weather forecast tool for astronomical purpose, as the author himself is a long-term astronomer and is always annoyed by fluky weather conditions.
