Has it come through a worm hole from another timeline perhaps ?

I don't think that is snow, just light flash off the wet surface. The other pictures don't show snow. More like heavy rain.

It looks like a Yak-52.

Not sure why it would be painted like that unless it was part of a 'warbirds' collection somewhere near.

it's a YAK-52, there are many planes painted like that...

they still fly them in airshow/look what I have groups

To the Russians it was a Yak-18, but to the Chinese it was a CJ-5 or CJ-6. You can tell that it's not a Yak-52 by looking at the curvature of the vertical stabilizer. The one in the picture is squared off, consistent with a Yak-18, whereas the -52's stabilizer is more rounded.
