Snow and cold looming

Any takers on guessing how much snow we'll get with the first Arctic blast of the Fall due this Wednesday? I'm thinking perhaps an inch, because it looks like a STRONG front that will zip through, and some snow showers behind with the upper-level low lingering for a day or two afterwards. It will be a shock to the system after that great 78 degrees yesterday to drop down to lows in the 20s. Yeah, baby... Fall in North Dakota!
