There have been a few chilly air masses that have reached the Mid-Atlantic/Northeast US in recent weeks, but the one destined to arrive here for next Tuesday and Wednesday will likely be the chilliest so far this season. A deep upper-level trough of low pressure will tend to rotate around and intensify during the next few days over the Great Lakes and southern part of Canada and then this system will spin its way into the eastern US by the middle of next week.
