.NEAR TERM /THROUGH TONIGHT/...
As of 1135 AM Friday...

Update: After evaluation of new guidance, have expanded the winter storm warning westward, with the warning now running roughly along and southeast of a Rockingham-Raleigh-Roanoke Rapids line. New high res guidance is suggestive of a band of heavier snow potential across the Sandhills into the central/NE Coastal Plain and far SE Piedmont, with the focus still on 7p-3a time frame. -GIH

No advisory for Davidson and Guilford is interesting.

12Z UK: this is 10:1 for all precip falling when 2M is 32 or colder and not just for snow. The stuff on and near the SE coast is about all ZR. So, CHS’s 1” of snow is actually 0.10” of ZR for example:

What time you think the precip starts in Charlotte area. 5?

HRRR continuing to initialize too dry down along the gulf coast and in the gulf.

This is showing up way sooner than any models I saw. With these temperatures, it’s not going to take much to start seeing some problems… very suprised that GSP hasn’t backed that WWA westward

How do you get the more sensative mode? Used to be pro mode on my iPhone.

BP thoughts....he's also honkin' a bit?

We see this happen with almost every system where the front edge of precip arrives earlier than expected, but typically it doesn't make too much of a difference in final totals. However, with temps so cold I think we could see meaningful accumulations from this before the main event gets started!

But....as @Myfrotho704_ pointed out the leeside (or not?) is starting to pop streamers right now

I don’t get this. I thought the whole purpose of that model is to ingest what’s actually happening into its next update?

Radar returns deepening near Columbia,SC of all places who wants winter weather there

Yup...this is a honk from BP and the piedmont

 

[Myfrotho704_]

The hrrr already looks juiced and it’s still initializing to low with precip

With as temps air and soil, as cold as they are I have to imagine that he's still downplaying accumulations a good bit. With that in-house model, it's pretty much snowing from 4-10. That's a solid 6 hours of what appears to be moderate and maybe some heavy snow. With ratios looking great, I'd imagine at least a good couple of inches for Charlotte. At least he is mentioning the dangers of the snow on the roads, so people aren't caught off guard.
