I must say this recent NAM run looks a bit similar to the recent GRAF evolution other than the tilt aside from the fact that the GRAF had most of the moisture as rain in NC/SC. I have had beef with the GRAF after two events last year which it did not do well with the rain/mix/snow line (Jan 10 it showed most of northern GA seeing all snow when there was mixing and Feb 20 it showed a lot more snow in spots that got rain), however it did decently with the northern extent of the precipitation shield on the Jan 21 storm over the ATL area, and maybe this time it is just struggling with thermals. This at least gives me hope that this NW trend may be legit, but the fact that the GRAF was over the Atlantic just a few runs ago does not help with the uncertainty part.
