It doesn't really matter to me...looking at temp profiles, I'd be rain anyway....perhaps the drier air could help me cool down some.

Pretty large dry slot going through GA right now...was this modeled?

The meso low is present on the surface maps right now. You can see a warm front pushing against the arctic front in SC and parts of NC. http://www.wpc.ncep.noaa.gov/html/sfc-zoom.php

This is hour 18 on the 23z.

HRRR is kind of a disaster for almost all of NC...why did it warm so much???

Well it looks like this time around, they're diverging. HRRR trending slightly cooler and NAM is trending slightly warmer. HRRR is way better for the Atlanta area than the recent 18z NAM run/

It's called climatology. Now large parts of the Atlanta metro is even struggling with 850 mb temps. Not surprised. It looks really similar to January's storm.

Surprised you're still so hung up on the GEFS...it was a huge failure last winter. Every member had me getting at least 2 inches of snow in the January storm. Nada.

Seriously, the RAP did the same thing in January. Showed my area getting heavy snowfall through dynamic cooling; In the end, nothing but rain with some sleet mixed in all day and snow showers and flurries the last hour or two. It puts too much emphasis on cooling the colomn along with overestimating the rates of precipitation. There's not going to be a wide area where rates overcome 35-37 degree temperatures.

The RAP always seems colder than actuality with these winter storms. Wouldn't put much hope into it. I'd go with the NAM 3km and the HRRR for my goto hi-res models when it comes to warm noses and thermal profiles. The RGEM also tends to do fairly well. The RGEM/NAM 3km combo nailed the big bust in January.

Not really. Some mixing issues at the start, but quickly changes over to snow before the heaviest precip gets there so a good event for Atlanta in honesty. Of course, this is only based on the 18z 3KM NAM model run.

I-85 storm to a tee from Alabama through NC with the widest part of the axis through GA.

Yeah that's odd. Even on the projected radar of the 3KM NAM, those areas are rain pretty much through hour 60. Here's the projected radar at hour 56 on the 3km. Not sure where that snowfall on that map is coming from for the eastern half of NC.

I love the look of the 3km NAM for my area. Snow from Hour 47-56 so far. EDIT: Looks like snow fom Hour 47-58, then scattered snow showers and flurries after. Don't seem to have much problems with mixing or warm nose...last year, 3KM NAM showed the eventual mixing issues I would have.

Euro adds to yet another model showing that warm bubble in East GA/Upstate SC lol. Limiting any real chance of decent accumulation there. Everything I'm seeing says you want to either be North or West of Atlanta when this thing hits. Sucks for me and other East metro residents, but not surprised.

Might actually be decent for the Atlanta area this time around. In the January 2017 storm, the 850 mb low went slightly to the north of Atlanta if I recall so the warmer 850 winds are coming in from the southwest and could never change over quickly enough. If it actually goes South of Atlanta, I might be a little more confident this time around.

Literally every model shows the warmer air in Athens/East GA area....the cold air simply can't make it over the mountains fast enough during the heart of the storm.

If we learned anything from January this year, warm noses are not easy to "scour out". I'd be very skeptical of models showing heavy snow through dynamic cooling.

Yeah that is true. Kind of sucks that I lost so much sleep watching this system via models over the last few days and get nothing for it, but a ton of cold rain.

You should take a weekend trip to the mountains with her.

These winter storm systems rarely rarely overperform. It's funny. After these types of storms are over, more often than not, people are complaining that they were dryslotted or precip. ended much earlier then modeled. It's just amazing how we can get so much precip. in the winter(December - Feb averages over 12 inches here in the Atlanta area), yet the occurance of a snowstorm actually giving you big numbers(12+ inches) is so incredibly, incredibly rare....in fact, it's not happened once in Atlanta in the last 100 years.

Seriously, this might be the worst storm yet over the last 5 years when it comes to teasing me about a good snow, then having nothing but a 33 degree cold rain. At least the other ones had sleet or freezing rain mixed in. That being said, not nearly as dissapointed because I had a huge reality check last night when the 0z Euro came in and it agreed with the NAM and RGEM. Just 24 hours ago, 100% of GEFS members had me getting at least 3 inches...I'm not even sure if I'll get a dusting at the very end. Note to Self in the future: When the Euro and NAM agree, lock that solution in.

Honestly, didn't some SC folks get a rare November snow in 2015?

Atlanta is not really getting snow though. I certainly am not. So frustrating. Every year a storm teases me to get 3+ inches and I end up with mostly rain/ice/sleet with snow on the back edge that just barely covers the yard and that's it. Even during the 2014 Atlanta snowjam, my area was no more than an inch of snow/sleet and ice. I guess this is nature's way of getting back at me for having 3 stellar winters in a row(2009-2011). It's trying to make this entire decade a dud for my area.
