I'm talking about GA/SC, not NC. The 0Z Euro op. has essentially nothing wintry for nearly all of GA/SC days 7-10 vs. the Crazy Uncle's major ZR/mix and keeping in mind the inferiority of the Crazy Uncle (thus the nickname).

With the crazy uncle the only model really on board, it's hard to get excited about. The threats keep getting less and less wintry with each run and each storm! Record breaking cold March? Not looking likely. Above normal rainfall, very likely! Winter is finished outside the mtns, except for Bricks flurry fest

I don't remember that many ice events in ga in March. It is usually rain or snow (not that it can't happen). So any model showing an ice event the closer we get to march and further in March we get doesn't really get my attention. Yes there have been snows in April but once we get (at least n ga) to mid march chances really start dwindling

In ATL, the last major ZR in March was all of the way back in 1971 (incredibly enough March 25th, which produced a big snow up your way I believe). However, there were also 2 in 1960 and one in the 1940's at ATL.

 

Edit: Folks, don't give up on winter if it doesn't do much through 3/5 as indications are hinting at +PNA beyond that fwiw.

Well, the 18z NAM is back onboard for the 2/26 flizzard.

 

And the 12z EPS mean indicates a Miller B, FWIW...

Yeah def one its better runs which I don't think it was off board anyway. lol. 

 

nam is similar to gfs in respect of the h7 level as far as more moisture and expansive precip shield. Also the best omega values along the VA border and NE NC. Could almost say that will be the jackpot areas.

Lived in NC (Central, Western) all my life (50+ years).

 

Don't remember any significant icing from late Feb through Spring.

Generally, after January... I discount that threat. 

 

Curious.  Historical references to major icing in this area during this time frame? SE, in general?

- There was major ZR 3/13/1993 before it snowed in northern Piedmont of NC.

- 0.5" of ice 2/27-28/1982 portions of eastern Piedmont of NC

- Three major ZR's in March, 1960: 3/2-3, 3/9, and 3/16-7. The first two included ATL and much of N GA.

 

Overdo for a late season major ZR? Neutral negative is the most favored ENSO phase for major ZR/IP in N GA at least. Of course, N GA, part of C GA, and part of SC already had a major ZR/IP this month.

Here is another from just a decade ago.

That was a pretty long-winded event, too, IIRC.  It seemed like it lasted two days, though I think temperatures were kind of marginal (30-32, I'd guess), so it probably wasn't as bad as it could have been.

Wouldn't it be nice if one of these systems coming up actually went in our favor, I mean where as right now the models don't show  much,  if all of a sudden they went in the opposite direction in our favor showing a snowstorm.  Its been a while since we've had one of these outcomes.  It seems its always the opposite, models show snow then they don't and never seem to turn it around in our favor.

 Fwiw, mainly entertainment, absolutely idiotic cold 3/11-12 per 18Z GFS. Winter is nowhere close to ending per this and other indicators.

Euro EPS mean, GFS EPS mean, CFSv2, Euro Weeklies, etc etc list goes on and on. 3/10-3/12 period seems to be locked in for return of more cold. How deep that cold gets is the only mystery here. Will it be 18z GFS cold? Single digit lows in TN/NC? Probably not, but this is exactly the reason why some shouldn't be giving up on winter threats. As long as there is cold around and until the pattern in the LR looks to flip for spring and summer, we're game.

I'm tired of all this danged heat.  I'm ready for winter!!  Can't sleet, or sleep, at night, fleas already bothering the pup.  Next it'll be mozzies, and months of despair, lol.  At least I'm getting rain.  Got 1.6 the other day.  I like a split flow, with cold over the top.  Always chances for a surprise the models don't recognize....and if nothing else...good rain.   Tony

What happened to the ridiculous cold that was supposed to invade this week?

 

 It wasn't nearly as ridiculous on any runs going back to 2/18 for KATL at least (coldest 17 and that in late Feb. vs. the idiotic 10 low and -16C 850 for 3/12 on this 18Z GFS). Of course, this extreme solution is in fantasyland and is undoubtedly way too cold.

 Yeah, this is the problem. Lucy is back at it again.  Was supposed to get colder this week and i will have probs just getting back down to normal. She jerks it away anymore for us non mtn folks and it will be too late anyway. This has been the most frustrating week in Feb in a long time. 60s and 70s for a solid week stinks this time of year!! :weep:

Yep I expect these kind of temps in April but not February.  You hate to waste a February week with temps like that.  Mother nature owes us a week so maybe in March we can cash in on a big dog and then I'd be ready for spring.  Just one more big one would be great.   :snowing:

Yeah, someone needs to answer this question. We're looking at slightly below normal temps and all rain right now. Hardly Polar Vortex II.

That's an easy answer. It's very common for models to overestimate the magnitude of cold air outbreaks. We see it every year. This time is hardly surprising. I know you're not suggesting otherwise. In all honesty, I'd be more surprised to see severe cold this time of year actually verify than back off as we get closer. I'm more surprised about the anaemic southern stream that was supposed to be active, producing copious amounts of precipitation.

I think it will, but it'll be in the form of rain showers mostly.
