One item to note reading through main thread. Euro nailed this current rain storm at 120 hours pretty much. Looks so so close with current conditions form here to New England with what it forecasted 5 days ago. To me that's a very good sign.
I kept looking at "snowdepth" on US Weather for real amounts and it wasn't near the high numbers 10:1 was showing. Snow depth to me is the most conservative maps to view anyway.
My gut tells me south and east is still good at this point. Gives wiggle room with temps. To @AlexD1990's point what I don't like is those runs were drier also. That trend needs to stop.
