Even though it's not a strict "Miller B", the whole setup feels like a hybrid one with a low riding up a cold front as the front moves east, and then transferring out to the coast.  Anything that even hints at "Miller B" seems to always be hard to nail down.

I had a comment that this seemed like this storm was a Miller B/Miller C hybrid- but no one seemed to appreciate my comment. It was mocked even.

Pretty incredible 10 years ago 202 would be 'the line' and even 15 years ago it would have been i95. Climo keeps pushing that line farther and farther n and w.

I think local development and more impervious surface/blacktop effect has a lot to do with this too which is also a man made climo effect.

I saw your comment.  The whole "transfer to the coast" thing always catches my attention.  I had never heard of a "Miller C" but apparently it is a "thing" with La Nina ENSO.

The 13z NBM doesn't look good (ice wise).

I disagree with this wholeheartedly. Climo has always favored NW areas of this region for as long as I've been alive. Hell the Fall Line definition in MT holly has always been N and W of 95.

It was always a B/C to me

Though technically for us it's an over running warm front style thump as the coastal does nothing here and hits New England

Not so much for ice (sleet/ZR) versus snow though.... Although I remember going on a senior class trip to Tamiment in the Poconos back in '79 in January and there was ZR that weekend with the slopes too slick to ski on and then the temps hit 40, so it was either ice skating in their indoor rink or board games. :lmao:

How this went from congrats S VA to congrats Boston in 48 hours is incredible.

That's why I wasn't hating on the suppressed looks early in the week. My weenie eyes have seen this movie too many times.

I think the 2000's/early 2010's really shifted perspectives to how climo actually is in this region...  Philadelphia itself has only gotten a 10" or more snowstorm 31 times since 1883.  Averages out to like 1 every 5 years. It really isn't a common occurrence, never was.

But 20 years ago this setup would never have pushed the mix line that far N and W as this one. And I understand this is more 700-800 mb layer stuff, but still. Yes, climo always N and W i agree. But when did i78 become the line? This is 4th or 5th time since 2018.
