Good points by one of our resident mets above. One thing I would say however is that with the previous event, most models 5 days out or so began to lose the big cold and teleconnections really weren't exactly screaming major cold either (weakish negative EPO signal), not to mention our friend the positive PNA so as it looks today, there seems to be a little more of a "favorable" signal for cold with some of those factors looking a bit more in play/bullish to me including the PNA reversal.

But as our warm traveler points out above, a lot can change between now and then so definitely going to need more consistency and data over the coming days before we can even begin to discern what type of pattern this evolves into, but this one looks different to me right now.

Let’s get that LES going on area lakes. AO and NAO for now look to go positive so my guess is the next big shot will have SE ridge at play.

12z ensembles are in, starting to see barney colors showing up on the EPS and GEPS, barney colors on an operational are crazy enough, but when an ensemble starts showing them, oh boy!

The final measurement is 6 inches of snow, as seen with the ruler. The snow ended at around 9:30 AM. This is more snow than all of last winter

We got between 5-6 here in jackson so far with a little more left. Not bad. I'm happy we didn't get shut out

Steve McCauley

The last of the snow flurries is fading away during the lunch hour, but the winter storm has left its mark on about half of the region. Snowfall totals ranged from 1 to 11 inches across north Texas with the BIG winner on the NW side of Sherman where nearly a foot of snow fell. MyOwnRadar detected lightning strikes in the area, so it is possible this was a thundersnow event.

As you can see from this graphic, the line that was predicted to separate the Snow / No Snow area was off by about an average of 25 miles. But for those who visit this page often were probably not suprised.

You will recall that the text of the forecast from 2 days ago stated the following:

"Keep this in mind: if the forecast temperature is off by as little as 1 degree, this will have a MAJOR impact on the predicted amounts of each precipitation type. "

And sure enough, the weather balloon data from last night revealed I was off by 1.5 degrees at the 5000-feet-above-ground level, which caused the falling snowflakes to mostly melt just before hitting the ground south of the Snow-No Snow line. Had the forecast been 1.5 degrees more accurate at the 5000-foot level, the snow line would have matched up well with the prediction.

Normally, no one notices when we are off by only 1.5 degrees. But this was a HUGE mistake if you are in that narrow band! But, of course, we mostly only hear from the folks in that 25 to 30 mile band that think the winter storm missed everyone, and that the forecast was a complete bust. :)

For you folks with at least a couple of inches of snow on the ground, your low temperature tonight may fall into the teens while the southern half of the region will fall into the 20s. This means any residual moisture will freeze solid, so take extra precuations as you head out the door Saturday morning!

NOTE: Some of these totals may be understated since some melting has occurred in the last 24 hours.

Great post by McCauley...Atlanta was the mirror image of DFW, went 1.5 Deg the other way and they are covered in a 6" plus blanket of white.

Confidence is increasing that the coldest air of the winter will be arriving between January 19-26. Still too early to tell if frozen precip will accompany this cold blast, but this could definitely cause ERCOT some issues. Sure hope we can get through this next cold blast without any rolling outages. I highly doubt we'll see anything extremely cold this winter after this next wave.

Looks like many parts of Texas will potentially have a below normal month. What's that?

Yeah, this one looks like the real deal...similar signs you see with the Big Southern Plains Outbreaks.

GEFS also has a major uptrend with the upcoming cold, no wonder why the CPC noticed the possibility of very cold and very snowy conditions in a couple of weeks

Yeah good summary post event, but this was essentially the point I was trying to make on here leading up to the event in that setups like these (upper level driven) are complex down here further south for these reasons and model "bust" are quite common because all you have to be is off by those temps margins he mentions upstairs and the model that seemed locked in for days with heavier snow/sleet amounts all of a sudden is off by several inches (in cases like Euro a bunch). It was truly a battlezone of precip types throughout the event across the DFW metro as precited but through it all, I thought the NWS did as good as you could possibly expect with those razor margins at play.

Not sure where you're getting that total for Atlanta from, but per the storm reports below, it was only a general 2-4".

You are correct though in that their snowfall was a lot "cleaner" than ours...

Yeah this will begin to get more attention early next week across all forums/media/social media should this signal continue. Right now focus is on the storm system that just exited our region.
