0Z Op Euro backed off on the quick .5-1" event in ATL but most of the ensemble members and new FV3 still have us getting some minor accumulation before the cold air sets in. As I stated before, that would be a traffic nightmare.

I am getting more confident that the Atlanta area could see an impactful event next Tuesday now that the Euro has come on board- even if it only an inch- with the temps falling quickly into the 20s by evening that would create a nightmare road scenario.

Huge difference between the 00Z GEFS and the 06Z (much less favorable here)- going to be a while before we get any clarity. Even on the EPS there are only a bit under 50% of the members that have accumulations in Atlanta.

The main threat I am seeing on the GEFS is a week from late Monday/Tuesday, not that much hope for more than a dusting with the Saturday system IMO.

For Atlanta, the Euro ensembles are still mostly saying no but the GEFS is on board with the majority of members showing at least 1 inch

I think that is exactly what is happening.

Pinch me, I will be headed to AVL tomorrow very early- if they get over 18" (and that seems to be a growing consensus) it will be the biggest snow storm ever there- also I have never personally seen that much snow in one storm.

Since here in ATL we will just get a nasty cold rain, I plan to travel up to the AVL area, the ensembles have been incredibly consistent with some very hefty totals, check out the 06Z ensembles- 14 members with 20" or more.

This is a big shift for the GEFS- previous runs had half of the members a trace or nothing.

This NAM trend is not surprising, just coming to the GEFS and EPS, a general 1-3" event here in GA, mainly from here SW. It was never going to stick much anyway, its early Dec for pity's sake, so no cliff diving here since I was suspicious of a big event all along. If I get a nice dusting to an inch or two on the grass it will be a bonus considering how much more of the winter is left.

Yep. 2-3" from Atlanta west.

EPS:

Based on everything I see, from over half of the GEFS members with at least 1" here, some with 5" +, the Euro ensemble mean being over 1", the new very impressive NAM- I think we see snow almost for sure now, some accumulations possible on grass, cars etc area. Fingers crossed for the NAM to be right, but need to see more evidence, but the trends are favorable right now for it at least not being a total bust.

All-time U.S. low temperature record threatened? The coldest temperature ever recorded in the U.S. was a -80°F (-62.2°C) reading from Prospect Creek, AK (about 180 miles north of Fairbanks) on January 23, 1971. A weather station just a few miles from Prospect Creek, the Jim River DOT site, appears to have recorded a low temperature between -78°F and -79°F Saturday morning (January 28, 2012), shortly before the weather station lost power. Keeping the power going at -70 is very tough, and it is not a surprise to see that the station lost power during this extraordinary cold snap. Power just returned this morning to the site, where the temperature was -66°F at 7 am AKST. Wunderground's weather historian Christopher C. Burt is corresponding with Alaska's state climatologist to get more information on whether the data during the power outage will be recoverable, and how reliable these near-record low temperature might be. http://www.wundergro...sters/show.html
