Pattern December 2023

Most recent White Christmas spatial map for NC.

Some areas along the US HWY 1 corridor and towards the Triangle area have been waiting nearly a century for one.

2010 was close but no cigar for most areas SE of I-85

Didn’t Concord see snow on Christmas Day in 2010? Not arguing but I remember snow on the ground Christmas Day!

I don't get this map. It snowed here on Christmas night in 2010. Wouldn't that be considered a white Christmas?
 
Hoping for crumbs:

RAH:
A cold front will push SE through the area Monday evening. At the
same time, a potent clipper like upper PV anomaly diving SE thru the
region may provide it`s own sufficient fleeting saturation by means
of strong dynamical lifting to support some scattered rain showers,
and perhaps even some flurries or a quick passing snow shower if the
snowflake can overcome a dry sub cloud layer. Lows 25-30.

I'll take it.

Snow occurred after local midnight on December 26th over the Triangle area. Closer to Charlotte, I think there's reason to believe the NWS RAH analysis that I based this on is incorrect.

Yeah I think it is. I was in Concord on Christmas Day 2010 until about 7:30 at my parent’s house, only a couple miles from Concord Regional Airport. When we left, there was already about 1” on the ground and it was really starting to pick up. At my house in Wingate, we basically watched the changeover happen as we were pulling into the driveway about 8:30… it snowed light but steady the rest of the evening enough to have a little over .5” before midnight. I ended getting dumped on for a few hours later that night into the early morning from the deformation band as the coastal low started cranking up.
 
Happy New Year from the GFS! And it’s not even 400 hours out! View attachment 138688
That’s a strong high, very cold look, low bombing in NE acting as a 50/50 low , almost a Jan 88 look, details to be ironed out, if it doesn’t go poof at 0z

I know it started snowing here on Christmas before it was even dark and continued through the night.

I’m just not smart enough to know why it fizzles out. Someone please tell me why.
If I had to take a guess that big low along the Maine and Canada border is just sitting there and it kinda squashes things to the south. Move that about 200-300 miles NE and let that 1041 high move in tandem with that shortwave and you have a really good Southern Slider overrunning set up.
 
Let's gooooo!!! Lol

The snow aspect of this storm certainly overperformed in this area. Roads were very slick and icy this am. Numerous calls for wrecks. Montgomery county closed all schools today. And we didn't even have a winter weather advisory.
That was a big win in your area. It's usually the other way around these days when you get a winter weather advisory and get close to nada. I miss those days when you wouldn't be under a advisory and still get a dusting to a 1/2 at times like you got last night.
