Thank you very much for posting this! Wow - talk about nostalgia! Those are the weather maps, and the meteorologists, that I grew up watching, and loved every second of it!
Interestingly, my cable headend's WeatherStar III didn't use the optional sensor package you see in use on the LDL here. Instead, our current conditions came from Boston's Logan Airport. The advantage was that our current conditions report on the Local Forecast and the LDL had sky conditions, but we had less almanac information (temperature and precipitation).
