I've had my MacCat deluxe in windy, snowy conditions. I like to have the front in semi porch mode because i like to see things. In early dec. i woke up at midnight with snow on my face and snow blowing horizontally thru my rig end to end. I got up and pitched the tarp steeper/tighter and that took care of it. You might want to think about a sock for the future if you think it would be useful. Something for your face is nice so you don't have cold air blowing in your face all the time. You'll probably be fine. At the every least it will be a teaching.
