Man, this forecast is teetering on the edge. System needs to close off/neg tilt. But if it does it too soon, then you get the 12z Canadian depiction which takes the frozen precip west and north. If it is too progressive and doesn't start until it gets east of us, then you get the 12z GFS depiction. And then there's the 12z Euro which is close... if it's just a bit farther SE, then we'd all be good.....
