===Nowcasting=== {{Main|Nowcasting (meteorology)}} The forecasting of the weather for the following six hours is often referred to as nowcasting.<ref>Glossary of Meteorology. [http://glossary.ametsoc.org/wiki/Nowcast] {{Webarchive|url=https://web.archive.org/web/20150527035615/http://glossary.ametsoc.org/wiki/Nowcast|date=May 27, 2015}} Retrieved May 26, 2015.</ref> In this time range it is possible to forecast smaller features such as individual showers and thunderstorms with reasonable accuracy, as well as other features too small to be resolved by a computer model. A human given the latest radar, satellite and observational data will be able to make a better analysis of the small scale features present and so will be able to make a more accurate forecast for the following few hours.<ref>E-notes.com. [http://www.enotes.com/science-fact-finder/weather-climate/what-nowcasting Weather and Climate | What Is Nowcasting?] {{Webarchive|url=https://web.archive.org/web/20110905132837/http://www.enotes.com/science-fact-finder/weather-climate/what-nowcasting |date=September 5, 2011 }} Retrieved September 8, 2011.</ref> However, there are now [[expert system]]s using those data and mesoscale numerical model to make better extrapolation, including evolution of those features in time. [[Accuweather]] is known for a Minute-Cast, which is a minute-by-minute [[precipitation]] forecast for the next two hours.
