Thunderly

Thunderly is a real-time weather visualization Chrome extension that renders lightning across a photorealistic globe. It combines live lightning with day/night cycles, real-time clouds, precipitation, and a one-hour history of storms to give you a global view of weather activity.

It offers interactive zoom for detail, a start–stop distance tool to estimate how far you are from a storm, and a playful feature to stream lightning via your camera flash from the opposite side of the world. There’s even a hidden real-time aurora switch for an extra wow factor.
