dopplerganger

A person who looks exactly like you and can predict the weather.

Mallory: Erin, I saw your doppleganger last night. She told me we'd have sunny skies tomorrow.

Erin: That was not in fact my doppleganger, but my very own dopplerganger!

Dopplerganger Effect

The effect of someone looking more and more like you as they walk towards you, and then less and less as they walk away.

I thought I saw my twin walking towards me, but I was just experiencing the Dopplerganger Effect.
