There will be deformation banding, the challenge now is how large, is it multiple bands, and where do they set up and move across. The fast movement argue that many will at least see it for a time even east of higher qpf predictions
NWS doesn't make wholesale changes this far out with things like this. They have brief updates for the very near term but not for something over 24 hours out. It's not smart to flip around so much with every cycle.Big updates will follow in a few hours. Adjustments are made in quicker times as the event is happening
I was even skeptical earlier today but seeing these trends and where the mid level low ends up Tuesday morning I'm more optimistic now. Models help guide us and now things look more reasonable to expect snow down to NYC and LI Tuesday.
Here we have some criticizing when forecasters flip flop and now NWS is remaining more consistent right now and some are upset and wondering why they didn't adjust. Surely if this trend continues amounts will be adjusted.
