Still interested to see if any lake effect or even sound effect snow could occur. This is a very cold air mass, and it has happened before. Many things (of course) could stop this; one being the dryness of the air. Air temps will be below freezing over much of NC but dew points much lower (20+ degrees lower).

Here's the 2014 event:

Lake Effect Snow in North Carolina? It’s Happening Today! - North Carolina State Climate Office

When you hear the term "lake effect snow", you probably think of the Great Lakes phenomenon that gives cities like Buffalo, NY, several feet of snow each winter. But this morning, thanks to a quirk of our cold weather, lake effect snow is happening right here in North Carolina! Radar and surface...

The amazing part of weather boards is if the possible storm on or around the 26th happens and hits the region with a decent to good snow , it will be remembered as “the perfect pattern” and will be forever enshrined in the “Hall of Fame” of can’t miss systems.
 
Didn't folks get sucked into the miller A GFS crap with the current system and then being sucked in again thinking it's gospel again. Can't make this stuff up.

You all may appreciate this. This is what a perfect pattern looks like in the SE. negatively tilted Pacific trough, positively tilted Atlantic trough, ridge north of Alaska. 6in+ snow in every state but FL.

What I'm curious to see is a SLPa &/or z500a composite of the big storms around here since 1901. You'd probably have to do some moving averages to the anomalies s.t. it's a more apples-apples comparison

I would love to do that, but the only way I can grab the data is through ECMWF's website, which is wildly inefficient. You can only grab data one month at a time and can take hours or days to become available. It's not at the top of my priorities due to the length of time the undertaking would be, but something I will consider.

KNMI Climate Explorer tool actually provides a work around to this where you can download the entire daily z500 dataset for 1900-2010 in one fell swoop. Hope this helps!
