When it thunders, a normal detector outputs a full signal, but an inverted one outputs nothing.

In rain or snow, a normal detector outputs a signal of strength 8, but an inverted one outputs a signal of strength 7.

At clear weather, a normal detector outputs no signal, but an inverted one outputs a full signal.

Behold! The weather detector.

Using the weather detector, you can make cool redstone contraptions that use the weather as a signal input!
