Reminder that most NCEP models include sleet in "snowfall" output. For upcoming storm, this will over-estimate near the big cities. Best option with NCEP data is snow depth change instead, which does not include sleet, and makes a 1st-order attempt to determine snow:liquid ratio. pic.twitter.com/awEO84KHUR
