There we go folks, we have model agreement.

LOL...No, no we don't. Let the models show this for 3 or 4 runs, then you have agreement.

We have model agreement with the 12z CMC and 12z Euro. I use blends of models and not just one model.

Oh yeah, those models too. As I mentioned before. Which ever models agree with the most, that's the most probable outcome.

Per the 18Z GFS, this would be the biggest sleetstorm for the city of ATL and south metro ATL since the great 1988 4" mainly sleetstorm..even bigger than 2/2014 for most except maybe the northern burbs. It appears that this major sleet would get down to Tony in south metro ATL and even further south per 850's being colder than +3 C. Macon would likely get a major ZR out of this as modeled. Of course, this is just per what the model shows, not a prediction.

I was going to agree with you Larry. That would be a huge hit here of ZR. My guess is it would be even colder than modeled but let's not get ahead of ourselves. Lol

Not wanting any kind of "bomb" until crossing over Florida.  Already bad enough as it is modeled from 18z for us down here.  Waiting until Florida cross to rapidly strengthen will help everyone involved in the Carolinas.

That screams massive ice storm for me and you Shawn

Checked surface water temps in the northern Gulf. Waters are warm, temps are in the 70s...some stations reporting close to 80. There will be some high QPF levels with this low.

I think Larry can back me up on this, you don't want a " bomb" low in the gulf! Too much waa, and could even be convections robbing moisture influx! Only need, want a 1003-1014 mb,low

Usually with a Gulf low, there will always be thunder storms down closer to the coastal area's. Sometimes those thunder storms can make it into colder air providing thunder snow. It just depends on the instability. The low should start "bombing" off the coast of the Atlantic.

That run just made me very happy. Too bad it is the 18z run though. Lol beggers can't be choosers, so I will take it!

Is the 18z run usually not a reliable run ? Should we toss it ?

18z is still legitimate and more valid than the 12z from today, simply because it initialized  with later information.

I will probably do a FBT live video later if yall want to stop by and say hello.

Mack,
I don't think he is saying he wants a bomb in the Gulf. I think he's just saying that even a very weak low with those warm SST's would produce a lot of QPF. The 18Z GFS has it at 1016 mb per my source. Per history, weak Gulf lows with this kind of track have been associated with many very wet SE major winter storms with liquid equivalents up to 0.75-1.25"+ well north of the low in much of the cold sector in some cases.

Some history of 1016-18 mb Gulf lows:

1. The great 4" sleetstorm at Atlanta and great snowstorm for much of the Carolinas and far north GA of 1/1988 1/7/1988: 1018 mb
2. Another great 4" sleetstorm at Atlanta and big snow for the Carolinas 2/17-18/1979 1018 mb
3. The great blizzard of Feb. 1899: 2//11-12/1899 1017 mb

Translation:  You don't at all need or even want a strong low while in the Gulf.

Too strong of a low will push too much warm air.

Yeah, I'm not quite feeling this event for a good snow around our parts.  I just took a peek at the pivotal weather GEFS snowfall mean, and it seems too much down this way for a mean.. but who knows.  Maybe those maps aren't separating sleet/zr either.

Don't worry reality is irrelevant to some

18Z GEFS mean is bringing more west coast energy eastward similar to the 18Z op. Trending in the right direction for sure. Should be some nice individual members.
