The document summarizes a web-based weather monitoring system in Palermo, Italy that collects temperature and other data from several weather stations around the city. It uses the data to analyze trends like the urban heat island effect and creates forecasts using artificial neural networks. The forecasts showed good accuracy within a 1-2 degree range when predicting temperatures a week in advance for different areas around Palermo. Future work will focus on longer-term forecasting to study thermal comfort conditions in the city.
