We have a Wireless Vantage Vue Weather Station on our roof. It is hooked up to our MacOS X Server, which is running the open-source Meteo package to collect all the data into a MySQL database. Every 5 minutes we send the data to our page at the Weather Underground and to our page at the Citizen's Weather Observer Program. The Meteo package also produces the historical weather graphs for 6715 Northrim Lane. (Using Bing maps).
