Message in the sky?

Here's a puzzle.

This zip fastener of a cloud was here this evening after the snow clouds had cleared. But, if you were an angel writing to someone down here on earth, the message would be upside down.
The angel was clearly taught to write neatly on a line.

And so, if you look at it from the angel's viewpoint, it would look like this!

Was the angel was as fed up with the snow as we were and  sarcastically commenting:
"another nice day . . .!" with a few scribbled words to follow?

If you think I have a problem with angels writing, may I suggest you Google "angel writing" where you may be surprised at the results; including the discovery that you can in fact write to angels. Here is a quote: 

With angel mail, you write your special request on a piece of paper and mail it to the angels.
