Re: Texas Winter 2017-2018
The cold signal is very clear for Christmas. As is a South Plains storm. We are still a week away from having any confidence on timing and temps.

Cold outbreak seems likely, still unclear on a storm this far out...although, the ENS dragging lower heights back across southwest, day 10, does increase confidence of a storm as it kicks out

Re: Texas Winter 2017-2018
Stepping aside from winter for a moment to address something that may become a problem down the road. We've had a dry Spring and Fall of 2017 for much of the southern plains. The double Nina, post hurricane landfall have been signs in the past for the formation of drought conditions. This is probably a good time to start getting yourself into mode of conserving water and planning for restrictions ahead of time to acclimate.
The PDO remains positive (barely) so that may keep us from a long term drought. But short term drought conditions have begun and will likely worsen as ENSO will not be of much help the next 6 months or so at least. Tough words to say but it's definitely in the cards right now. In its infancy, it is mostly an atmospheric and environmental drought thus far, the lakes have not taken a hit yet but hydrology interests may be effected down the road.

Re: Texas Winter 2017-2018
Wow, I log in for some possible fun Christmas Cold (and hopefully snow) updates and get this dire outlook
Just giving you a hard time obviously. I too have been worried about the implications of this dry period. With a lake house that is impacted by water levels, this selfishly applies to me more than the average person that just thinks water is always there. Hopefully in addition to some fun winter weather we can also get some impactful rain, preferably really cold rain that transitions...

Re: Texas Winter 2017-2018
0z GFS at 240 hours(December 21st) is unloading the arctic down the plains... front dropping into Kansas
252 hours racing into OKC and the Panhandle is already cold -20 in North Dakota
Arctic front crashes through Texas at 288 hours, Dallas is near freezing on the afternoon of December 23rd.
A little wintry mix in the metro and rain to the south then the front sort of stops moving or something. Christmas Eve is near seasonal levels, then Christmas Day is very cold with temps crashing through the day

Re: Texas Winter 2017-2018
Yeah 0z GFS is an arctic dump straight down the plains. Big trough vorticity yet to kick out in the west. Slight SE ridge to center it over us.

Re: Texas Winter 2017-2018
As the run ends there is another large High coming into Montana... if it verified, that would be the motherload of arctic air leading into New Years

Re: Texas Winter 2017-2018
Euro has no sign of that 240 hour GFS arctic front it seems... much warmer in the Dakotas than the GFS
But it is the very end of the run
looking at the GEFS there's a clear signal for cold air and some precip around Christmas

Re: Texas Winter 2017-2018
Geez I should know better after all of these years, but I’ve got to admit that these GFS runs around Christmas have got me excited.

Re: Texas Winter 2017-2018
It appears we are setting stage for the La Nina trough pullback. The time of the eastern deep trough is coming to an end on the ensembles as cold air will be driven in the plains and rockies. The southeast ridge is popping up more and more while the Alaskan ridge is deepening on the ENS. OP should continue to trend that way. Christmas week may be cold in the front range and plains while potential torch in the southeast US
Can't hold back the Nina for long east coasters.

Re: Texas Winter 2017-2018
Perfect arctic outbreak for Texas. The 06z dumps even colder air on us for a longer period than the 12z

Between the boundary of warm and cold will likely see a barrage of various weather. Rain, ice, and snow in such a pattern from panhandle hooker type systems. They should dive down the great basin and bend up northeast (negative tilt) as the SE ridge is a block aloft. An axis from Texas/Oklahoma/Arkansas northeastward could be the battle zone with northern side snow/ice storms potential in those tracks.

Re: Texas Winter 2017-2018
The second half of December sure does look active in the latest long-range model guidance. Since we've already had one snow event in south Texas, another one would just be icing on the cake!
But more importantly as Ntxw mentioned a few posts back, we need to keep the precip chances coming. I really don't want another 2011 summer next year.

Let’s see how much that SE ridge flexes. Usually arctic air masses win out. I could see a LA/MS boundary given how cold this airmass looks.

Re: Texas Winter 2017-2018
What's it looking like for us south of San Antonio with Christmas time weather pattern?
BTW since I really haven't had time to be the weather geek I used to be, what's the best link for the weather models you all reference?
