I agree the Nam is probably overdone but if it has the right idea as to evolution, mainly bringing the 850 low up into S/W PA, we are not going to have a fun time with this. Bob Chill just said he thinks the Nam has the right idea so not everyone is just tossing it aside. I think we are all still getting some snow either way.
A voice of reason? Good analysis. I said it was the worst nam run due to ground truth temps in the 40's (12Z got their as well but had more frz) but it could have trended a bit better.
Yea. And I was not aiming that at you vs. using your post as a way to avoid issues as both you and I were doing PBP and not forecasting. I want snow and lots of it so let's hope the Nam evolution is wrong.
Going to take the chance to here to comment, this is JUST a model PBP. Not a forecast, not a cheerleading effort, just facts on what the model says. If other suites show nothing like this, then dandy.
We can say its the Nam and ignore or use it as a tool. No matter what, the Nam was on to the Western extent of the 850's blitz from the very beginning. it could still be wrong but if not, it gets a gold star for its effort.
850's at 57 well up into PA as to 32 line. Most of South border PA is now frz west to east. The inland low gets too far up again. Inland wave sitting in WV at this point. Total failure if that happens. No good news from here so PBB over. LOL.
Anytime I see sleet getting into SW PA, I know I am toast unless something to my east starts deepening rapidly and closing off the assault. Like you said, its not depicted to the east right now. Its coming in right overhead.
