This isn't a guesstimate. We have a Boltek mounted to the attic of the lakehouse; it plugs into a PCI card on the server and records strikes from hundreds of miles away.
With JavaScript enabled, most conditions are updated at 5 second intervals. The long-range forecasts, weather warnings, and radar data are fed via NWS, HAM Weather and NOAA condition reports. This weather station also feeds weather data to Weather Underground, Anything Weather, and the Citizen Weather Observer Program (CWOP/APRS). This site is updated by Weather Display and WeatherLink software.
The weather station's "sky cam" is mounted to the same pole as the weather station, so you're seeing the weather that it 'sees'. A new sky cam image uploads every ~2 minutes.
If you have a questions or comments regarding the weather station, webcams, etc., you can leave a post in the North GA weather forum.
