My own modelling is showing low pressure moving E to NE with it over the C Lakes by New Years Eve, and New Years Day, (in my holiday forecast thread) I show high pressure over the upper Midwest with low pressure over the E Lakes, which I posted 2 months ago. I had thought it could be a clipper sinking in over the plains, back then, moving east, but looks like a CO low set up. A secondary low moving up from the south over the east lakes wasn't on my radar for the 1st, but sneaky things do happen
