Early winter, early spring?

Looking at ATL since 1950 as a proxy for the SE as a whole:
When Dec was 42 or colder (3.5 or more colder than normal), Jan was 42 or colder 10 out of 14 times.
When Dec was 40 or colder (5.5 or more colder than normal), Jan was 42 or colder 6 out of 7 times.
When Dec was 49 or warmer (3.5 or more warmer than normal), Jan was 42 or colder only 2 out of 15 times.
When Dec was 51 or warmer (5.5 or more warmer than normal), Jan was 42 or colder only 1 out of 5 times.
Any correlation with Feb, Larry? I.e., an actual colder winter in general. I'd almost rather have normal all the way to the end of March, than a cold Dec/Jan, then sudden spring onset, lol. At least one of my winters in the last 16 had a very cold late Nov/ Dec, and that was it for winter...don't need that....... And some good rains, I be happy with that, and take my chances with the cold air. Can't live without rain, and snow/sleet in Ga is kind of rare, in that it rarely happens all over, lol. But when it rains, it's usually all over, and most everybody wins..funny how that worksGaWx link said:For those hoping for a cold SE US Jan., it is better that Dec. be cold than warm because there is a decent correlation between Dec temps and Jan temps.

Yep, it's truly weird, Larry. Rain dump, drought, rain dump. It's not like I often get 5.1 in a few days, lol. The 18 inches in 2 weeks in Dec was what started this anomalous string of anomalys, lol. And I ask you, why can't I ever get 18 inches of sleet, or snow over a two week period? It's not like it's physically impossible....well, 18 inches of sleet might be rare, lol. Hard to imagine the contortions the atmosphere would have to make for 18 inches of sleet, lol. The Goldielocks effect gone mole crazyGaWx link said:Yeah, Tony, sometimes wx works in mysterious ways. That's my way of saying I don't know.Might your moles somehow have something to do with this?
One thing I'll note is that the dry spell was during a climo relative dry part of the year. It really doesn't like to rain much in Oct in ATL outside of the rare Oct tropical cyclone big influence as you must know. Outside of El Nino, it doesn't typically rain much in Nov in ATL.

Dsaur link said:Hey, Shawn, good to see you!! Hope this is the winter SC sees something other than hot and dryIf it comes thru me, it'll get to you, so here's hoping I get that elusive north central sled enabler
Turns out I miscalculated my additions and I got over 5 inches of rain since it started back. Did the drought get you too? And how much did the turning on of the flow bring you? Tony
Dsaur link said:I just hope it rains all winter, I'm tired of dry. I'll always take too wet over too dryIf it turns to ice I'll deal with it...I've cut down all the pines that can make the house, so I don't cringe as much..until one of those oaks near the house cracks a big limb... but if it's going be real cold at times, that lets sleet in the mix, and snow. Meteostar had me with some pretty good minus numbers out in lala. I'd love to see some of those actually happen. Haven't seen a bitter cold Christmas in a while. 12 or 16 on Christmas eve would be different, lol. Does it a lot at New Years Eve, but usually not Xmas. It's fighting climo, I guess. T

Dsaur link said:I'd be ecstatic if we could get a nice little snow starting on Christmas Eve with temps 20-25 degrees. I just can't recall anytime in my life that it snows here that cold, or at least starts that way. Usually we are just above freezing and the melting flakes cool it down on the surface and we see a changeover. It really would be nice to not have to worry about temperatures for a change.
Larry, have you found any correlation with years that have had major at in the N GA area? (2001,2005,2015,etc)GaWx link said:ATL over the last hundred years has averaged only 0.3" of SN/IP in Dec (0.1" 1st half and 0.2" 2nd half). That is only ~15% of its average seasonal total of ~2". Only 18 of the last 100 ATL Decembers have had measurable SN/IP. In contrast, 0.8" has fallen on average in Jan over the last 100 years with 45 of them having had measurable. In Feb, 0.4" avg/30 of them had measurable. Mar: 0.4" avg/15 of them. Note that most of this is based on the airport, which is south of town. A few of the years are based on downtown. The northside is obviously higher in freq/amts though I have no hard stats. My guess would be that the northside gets ~3"/year on avg. Regardless, this gives one the idea about Dec being relatively quiet.
Aside: Back in the late 1800's/early 1900's, Feb was a big SN/IP month with close to 1.5"/month!! Jan was near 1.4". Dec was near 0.7". (Mar was only near 0.1".). So, seasonal SN/IP was ~3.8" or about double the subsequent 100 years' rate! One reason: it was colder then on average, esp. in Feb. Also, the station was in the city, not south of town.
Looking at history, ZR's don't pick up there too much in frequency til the last week of Dec. I will reiterate that due to us being in neutral negative ENSO that this winter's chances for a major ZR or IP are ~50%, which is about 3 times the chance for other winters. Most major ZR's there have occurred between late Dec and early Feb.
