Here is a less redneck version that would work as a sun/rain shelter for the OP and 4horses or as a snow awning for 2dogsfarm.

It would require two or three pipe gate or fence panels. They have an additional kit for side “walls”, or you could simply attach tarps to the sides.

I’ll get some photos of what we have as soon as I can get my camera working…

While I’ve dealt with preventing rain collection, snow is an entirely different matter. We get very little snow most winters here in NW Oregon, so we just sweep it off as it falls. My redneck pony tent works for us, but I’m doubtful of it working in real snow.
The biggest problem is that snow won’t just run off as rain does. The angle would need to be steep enough to let it slide off, and the cover would need to be fairly rigid.
I would use a tarp, either canvas or UV resistant, heavy-duty reinforced polyethylene, or possibly sail cloth.
