If it makes you feel any better I wouldn't trust those CPC maps anymore than I can throw them. They change just as frequently as any typical computer model run will.
Here's an interesting article from Accuweather talking about the return of arctic blasts by next week. What jumped out at me was the mentioning of a Sudden Stratospheric Warming, I wasn't aware there was one earlier this month. They think the brunt of the arctic air will be aimed towards the Midwest/Southeast/Northeast regions.

There have been March's in the past that were notorious for snow/ice here just as well as DJF are. (ex: 1960, 1980, 1983, 1993, 2009, 2010) those are just the years I know off the top of my head, there's probably more.
