The trend today has been a little further north because it's stronger. I talked about this yesterday when I posted the DGEX. It is a definite possibility and one that I am beginning to find intriguing. I think the purple track is OFF the table. We'll be somewhere between Green and Blue track, or slightly north of blue track

Warm Air Advection. Think of it this way, Skins. You know there's a warm front at the surface, but it isn't ONLY at the surface, it's throughout the atmospheric column. Because cold air is much more dense than warm air, the warm air being brought northward on the southerly winds ahead of this system is forced up and over the cold air. Where the warm air is able to remain at the surface, those areas are behind the warm front (at the surface), but it reaches a point where it can't scour out the cold air entirely, and so must flow over the dome of cold air. As it continues northward the cold air becomes deeper. The division between the dome of cold air beneath the warm air being ADVECTED over it by the winds is the same warm front as it is at the surface, but it's just higher up. And, in practice, the warm air will look like a wedge on top of the cold dome if you took a vertical cross section through the column. As long as the cold dome can remain cold enough through the precipitation formation zone, it will snow. The shallower the cold air becomes, the "warmer" your precipitation becomes i.e. sleet-->freezing rain-->rain. Make sense?

Thanks man appreciate it
