To cancel or not to cancel

I'm debating cancelling the snow camping this weekend. All the news reports say that another big storm is moving into the area and will dump a lot of wet on us. However, the NOAA web page says that it will snow, but I can't tell how much. Our tents can handle a light snow, but not anything over 1 inch or so (at least that's my guess, their 3 season tents). I don't want to put anybody into a bad situation. I also don't want to think we can do it and then have to abandon in the middle of the night. I'm leaning toward canceling.
