The “snow hole” on ATL radar is starting to shrink, implying we are seeing a more Rapid moistening of the atmosphere and getting closer to them seeing flakes

You’re welcome. I’ve been spraying the water hose in the air to moisten the atmosphere

I'm off St. Mary's near Glenwood Ave.  Hopefully the precip line doesn't set up between our group.

lol.  Great sledding terrain near you .  Lived on Cowper several years pre-covid.  Jan 2017 provided some of the best street sledding ever!

Light snow/flurries in Perry, GA. Current temp is 32.2.

Otherwise, the gulf low which we`ve been monitoring for several days
now still has the potential to produce some snow showers across our
southeastern zones this afternoon and tonight. More of the latest near-
term guidance now depicts a bit more QPF along and south of the I-85
corridor. The best forcing and moisture remains at mid and upper lvls,
while low levels remain dry. Mid-level isentropic lift will spread NE
across the region this afternoon, but with such a dry and deep sub-
cloud layer, much of what falls from the mid-level clouds will likely
be lost to evaporation. Nonetheless, snow flurries are probable this
aftn/evening as this lift strengthens, and it`s looking like we may
see some accumulating snow along and south of I-85. After consulting
with our neighboring fcst offices, we decided to go ahead and issue
a Winter Wx Advisory for snow, that runs from 4 pm today until 9 am
Wed morning. This was largely driven by the potential impacts on roads.
With the cold air in place, any accumulating snow may cause significant
impacts on roadways. Temperatures, meanwhile, will continue to be well-
below normal thru the period, barely getting above 32 degrees over much
of the fcst area today.

Montgomery, AL, had light snow just start. It is increasing in Hattiesburg, MS, and continues heavy in McComb and N.O. At Mobile it started 3 hours ago. Pensacola NAS just stated getting flurries at 11AM EST with 28 and DP of 20. An hour earlier it was 32/8.

These high-resolution models are very interesting on our snowfall amounts now. Even the GFS ensemble mean doubled snowfall compared to previous run and is a lot wetter. If the freezing rain does happen to be limited as these models are starting to suggest, we might be in for a lot more than 2 inches of snow/sleet if temps cooperate as well.

warnings extended west

My in-laws go to Florida every year to get away from the cold and snow. They are camp host in Destin at Topsail State Park. I'll post pictures as they send them to me, looks like they ar about to pick up those heavy bands coming out of Louisiana.

As I thought the dry air is preventing any snow from reaching the ground, looking at the radar would not be surprised if we get nary a flake.

[Brick Tamland]

Short range models keep going back and forth from further west to further east with the precip in NC.

Looking at the virga circle closing up and the radar overall I do think steady snow will fall from I-20 south.  could see the line setting up slightly north, still probably 90 more minutes til anything falls

Assuming you’re not down under.

Could I suggest an edit to thread title (to 1/21 - 1/22)?

Wondering if arctic front intrusion into n FL is overdone on some models, could stay a cold rain  with sleet in s GA and snow into c GA? (think it would snow in FL panhandle west of TLh so sleet in border counties to n of JAX).

I'm back in Georgia briefly visiting the family before I go back to Australia this weekend. I just happen to be here during this snow event lol.

GSP Radar off line?

Yes. They’re having to do unscheduled maintenance on their doppler radar due to a malfunction. They posted about it on their facebook page two days ago. Supposed to be down for several days.

This map pretty much echoes what I have thought all along about this one.  Who knows if it ends up being reality or not.  All I know is systems like this have a hard time overcoming truly arctic air on the fringes.

[Blue Ridge]

Flurries in Southern Pines, per Chick Jacobs’s feed. Nothing directly overhead on KRAX. 

[PennyForYourThoughts]

All roads and bridges in Mobile are to be considered impassable, by the DOT there.  Fla panhandle here....can barely see any grass now...completely covered and snowing heavily. . and its 25 degrees. 

[wncsnow]

Never thought I would see a freeze warning NORTH of a blizzard warning..

[marsman]

Wake Co. schools that were in today are getting out an hour early.... which is if not now, very soon. Very short day too - they had a two-hour delayed start. I'm betting they're closed tomorrow and at least another 2 hour delay on Thursday.

[Brick Tamland]

Well, after increasing totals further west of 95 in NC earlier today it looks like the models have been decreasing them the last few runs. I might be lucky to get an inch of accumulation. 

 

[Seminole]

Well this is a new one. Hurricane Hunters flying into the winter storm.

How the heck can New Bern get 8" with Greenville up the road only 2"? I can't imagine a gradient like that here on the coastal plain for such a short distance but of course anything's possible. When's the last time you got 8" down there? 

I don't remember ever getting that much although we were close in 2010.

[SnowGoose69]

Euro .08 liquid still for ATL, for those in FFC .12 shows snow 19-00Z.  Radar about to close up the virga hole so might begin very soon.  MGM interestingly is struggling so far, sometimes in these setups dry air aloft can push harder into AL/MS than GA

Howdy neighbor. I'm 10 houses from Honey Baked Ham.

Man, it's looking good for the Lowcountry!!! These totals would rival or even surpass our 2018 storm.

It just started snowing here.
