Anytime you have confluence around and it could be a major player, you can't let your guard down, even inside of 24-30 hours. This rings true whether models are consistent with a big hit or something more of a brush.
Remember back in I want to say winter of 2017-2018, I think it was second half of winter, there was that big storm and models underestimated the confluence and what was looking like a good 1-2 feet for Connecticut ended up being a Long Island special.
