timing is so critical in these situations..if the low starts getting it's act together 2 hrs later the eastern boys hook up..
i assume you are referring to NYC? the temps where hovering around freezing most of the day..
lows tend to move towards their upper low , i guess the models just couldn't handle such a intense 500 system , thus the inconsistencies from run to run..
warm days at A Basin can be fun too..
