Live cam in Asheville. Looks like light snow there.

AshevilleWX

Located in the heart of Downtown Asheville, this camera is situated on the top of the Grimes Teich Anderson Building and views the entire town. Heavy snowfall and slick road conditions can be seen from this camera in the winter, and wonderful sunset can be found during the evenings!

you've got to cool it from the top down the sfc will legit be the last place to cool or maybe you are lacking good caa

Big white fatties falling in Florence AL... nice

 

[FallsLake]

RDPS as increase accumulations from that last run. We're far enough into the event these runs don't mean much, but it's good to see them not decreasing (as the NAM did).

I guess it's coming even faster than thought. The CAD is breaking the 925 down to freezing as we speak across N GA, so that layer is almost done. 850s crashing almost vertically it appears in N GA.

It dropped from 41 to 38 over the past hour and a half here in ATL. Dewpoint has seen a similar drop from 38 to 35.

EDIT: Those NE winds are no joke, been gradually getting stiffer all morning.

HRRR keeps showing this little feature. Think my hopes are riding on it? My kid in Hampton area might get blasted though. Good luck to you guys in NE NC and such!

He's actually entering a warmer pocket of 925 going up that way. The CAD is actually to his south now. It'll eventually fill in though.

Almost all snow Clayton 36

While it’s still raining here in East Charlotte, It has gotten noticeably colder.

This can’t be right, can it?

Actually, this has been showing up off and on in various models for several days (I think the UK had it two days ago). If you look closely, you can it on today's RGEM, and it actually adds ~.10 qpf to GSO. The HRRR is a little west of that.

 

[Webberweather53]

12z HREF probability matched mean snowfall. Went up considerably for folks south of the Triangle, consistent w/ recent trends in the NAM & HRRR.

 

[Blane20181990]

Sleet and flurries in Pikeville NC is getting heavier as of 10:30 AM!

NAM has gust into the low 30's here with mod/heavy snow overnight.....

? ? ? ?

To add to an earlier post, here's an animation showing that the HRRR is definitely speeding up the changeover to snow for folks south of the Triangle area. This is like music to the ears of snow lovers in Charlotte, Fayetteville, & Goldsboro, etc. Also starting to increase the potential of snow for parts of the upstate of SC as well.

And as you and I and some others have been trying to say to everyone the past day .. THE HRRR is trash in its long range and as we get closer it will cool like the rest of them .. the question was the precip not the cold ... and we have the precip... and we now definitely have the cold

 

[JLL1973]

snowing here. too bad its 36 degrees

 

[NCHighCountryWX]

This is a massive bust for the NAM west of US 1

The HRRR will always whip it when it comes down to go time. The writing was on the wall early yesterday evening

 

[Myfrotho704_]

really liking this look living NE of CLT, just gotta cool sfc temps through dynamic cooling

Like clockwork ... long range HRRR= ?

 

[ghost1]

Nice surprise for NW AL... ground is white (streets are fine) and still have light snow falling. Temps have fallen from 39° when the first flakes began to fall to 36° now.

 

[John1122]

Had to war with virga for 2 hours but was all snow from the get go once it started. Probably 4 or 5 hours to go.

 

[jackendrickwx]

WWA for Gville and Sptbg Counties.

 

[Deleted member 609]

Holy poop balls the precip stays back for a while on this run. I get more than Brick!

 

[StormStalker]

Man it’s just coming down here good. Been mixing with rain but this is a pretty snowfall. To bad it’s really not sticking much.

 

[Cadi40]

I’m very curious on the models as to why that lollipop in Union county keeps showing?
