Wintry 1/7/17-1/10/17 Winter Storm

00z EPS has a better storm signal on the mean boys.
 
On this date in 1963-64, a massive snowstorm struck northern AL, eastern MS, and TN, producing upwards of 17" of snow in Huntsville and about 20" in Florence, AL! The Atlanta metro picked up ~4-6" and snowfall in North Carolina was largely confined to the western piedmont and mountains...

For some reason a lot of the station data cut-out &/or was missing during this storm in central and western NC, so I didnt have as much data to work with vs what's "normal" for most winter storms in NC during the 1960s..

Whew. No major ice storm on the 06z GFS.  Waits to pop the low off the SC coast. some snows in northern AL, parts of TN and a chunk of NC.  of course with some mix/ice mixed in.

edit: little bit of winter in N. GA also.  nothing crazy like the I-20 ice band, thankfully.
 
A shortwave over southern Alaska just passed over a couple upper air stations in the southern portion of the Yukon Territory, and ingestion of this vital upper air data into the models likely was the cause for the extreme shift in the models overnight regarding the threat for wintry weather in the eastern US ~ January 7-9. I think we need to look at another run or two, but given that virtually all the models (except the UKMET which had this solution the entire time) responded in the way they did immediately after this new data was ingested, this shift could be legitimate. There's still a considerable amount of uncertainty left at hand, but we may have gotten much closer to finding one important piece of this non-linear, stochastic puzzle next week...

Nearly a week earlier just before Christmas, approx 14 inches of snow fell in Memphis on Dec-23 with a record low of -13F on Dec-24.

Interesting! This is the first I've heard about that storm in TN, as I was skimming through the NWS data, I definitely started to pick out another storm in this timeframe over central & western NC. Southern TN must have been loving this, back-to-back 1'+ snows in some areas between Huntsville, AL & Nashville, TN.

Looking at the NCDC RSI data, you're definitely right, that's a butload of snow from southern AR thru PA...

Well, I'm old enough to say I experienced this storm. lol

Well, I am glad. No major ice storm as of yet. Hopefully rain changing to snow.
 
Maybe the dgex is on to something for once and the 12z runs will bury us
 
Good morning members, could be another fun day here on the site. The guests need to sign up and join our discussion. Remember, things will start to get really active around here if the models continue to show the potential major winter storm. And, the guests viewing will be turned off.

I like the 06z GFS, the high placement is right on. There would be more snow with that setup...still some CAD but nothing like the 0z GFS had CAD wise.

This is from meg. Doesn't sound too good
Tuesday will be cooler and dry...with another reinforcing cold
front ushering in much colder air Wednesday. Some guidance still
includes a chance of wintry precipitation during the later half of
the work week...but both the GFS and the ECMWF are trending drier.
Will continue to lean toward the drier and more climatologically
favored solutions.

Models aren't continuing to show any major winter storm. Actually, they are trending away from the idea, and gaining consensus with each other. Could they all be wrong, sure, but right now, it is suppress city (may be a good spot to be in right now).
 
For what it is worth, my TWC app went from rain to mostly cloudy to rain/snow mix to snow.
 
Strong storm signal on the models for next weekend. Hope it continues and it is just a matter of figuring how much we will get.

yes, this is actually what the SE board needs ATM (what is your location? every member needs to complete their location information)

I'm not worried about that suppression this early in time. We've seen enough consistent runs that there will be winter wx across the south in some shape or form...it may not turn out to be a major event but the whole idea of a winter threat is there.

App forecasts are useless this far out, just know that. Most of them are automatically generated either with GFS/RPM in house modeling or both.

Same here, but I've lost all faith in the #crapapps.  I think the stock weather app on the iPhone is integrated with TWC.
 
I will say before people freak out on the suppression, that it was almost a given we were going to see extreme model runs. The next 2 or 3 days things will begin to sort itself out. I would be surprised if the system was a suppressed and as dry as advertised at the moment. I expect models to trend back more NW with more moisture on future runs. How far northwest and how much moisture that is the question. Of course we could get squashed by the northern stream but I would bet against that at this time. :snowflake:
 
As always here in the southeast, we have to thread the needle again

Wondering when does the Para run again?

It looks to be running behind...I guess.
[/quote]
It sometimes skips runs randomly and it's a known thing with the para. It will either run at 12z (a little later than the regular GFS), if not it will hopefully run tonight - but the 00z from last night wont be posted as it was never ran, if that makes sense.

Suppression is our friend. Doesn't that also quash the SER?

Yes, it does squash the SER.
