How does the jet stream move storms across north america?

Storms are made from a combination of warm evaporated heat that falls back down near sunset, some fo the jet streams curve for hundreds of miles one of them curves from NA to Antarctica and all the way back in a huge belt, the storm once caught in a jet stream will go where ever the jet stream goes, and a good bit lead across NA.

I hope this helps

It conforms what ever surface its in.
