Models will chop and change on each run, the pattern is still there, it's still going to be bitterly cold next week and beyond, with no real way for any milder weather to come back in.
I feel some level heads are needed this morning, and there is really no point in pinpointing where it will snow and when until really, Sunday night?
Just take note of Fergie's post, no point in looking at too much detail yet.
