Worth knowing

Weather Underground was founded in 1995 and is one of the oldest weather platforms on the internet.
WeatherBug operates its own proprietary lightning detection network across the US.
Weather Underground's WunderMap lets you toggle dozens of data layers including pollen, wildfires, and webcams.
WeatherBug's free tier is notorious for aggressive ads — premium is almost a necessity for a clean experience.
Weather Underground is heavily used by storm chasers and amateur meteorologists worldwide.

Weather Underground was named after the 1960s radical political group — founder Jeff Masters thought crowdsourced weather data was about as disruptive as activism. IBM apparently kept the name anyway.
