Where I used to laugh at TWC's forecasts, they've actually been getting much more accurate of late. Not saying they are perfect, but I like to monitor what they have, as well. I guess they use some kind of blended model run that's proprietary. Not much info about it, but that makes sense since it's proprietary.
That said, while most models are scaling back totals, they hold serve over night with their call. But this is where it can get tricky and why I hate trying to be exact. TWC has been sitting at 3-5 inches for 48 hours. Most models have gone from around 7 inches to down to 2 inches and in between, run to run. So while it looks like a lot of movement in one and nothing in another, they pretty much are still calling for the same thing.
At this point, it doesn't look like there's going to be a ton of moisture for us. If that's the case, I'm thinking high end would be around 4 inches. Realistically, probably get 3, but since we'll get sleet and drizzle at the end, if you were to measure at the end, it might be around an inch. N PA will probably do better, but not much. Like in the 4 to 6 range.
