Isn't the snow suppose to stop in January?

So it seems like winter is never going to end. We actually had gone a couple of days, maybe even a week without snow and then last weekend, we got hit with a bunch of snow, of course on a Sunday morning, but lucky for us we don't have church until 1 so no biggie. So I dressed the kids and they came out and "helped" shovel the driveway. Really they just climbed on all of the piles of snow, but Keegan's little legs kept getting stuck so I would have to stop and rescue him every couple of minutes. They got pretty cold pretty fast, so they went in while I finished the driveway. After the snow, it seemed we might be done, but nope, this morning we woke up to snow again. Right now it really isn't sticking, so hopefully it will stay that way. We are planning on driving out to Iowa soon and I hope that we don't get stuck in the middle of Wyoming and have a huge storm come through and they close the highway down. That would not be fun with 3 little kids!
