Euro has finally joined the GFS but keeps the coldest stuff for Tuesday 12z. Showing a low of 17 in Downtown Houston. Keeps all precip liquid with a change over to snow towards the Brazos Valley.

A freeze of this magnitude has been well documented many times in this area. It only stands to reason it was going to happen again. I don't think it's a question of if but how bad. It's all about the snow/ice cover I think at this point and how fast the skies clear.

GFS is definitely a worse-case scenario and it seems too unbelievable to be true. Not saying it can't happen but that's a perfect storm of heavy snow or ice accumulations and a clearing sky like Andrew alluded to. Strong radiational cooling could in theory cause our temps to tank to near all-time lo...

Here's a look at the raw GFS output for IAH. Highs in the 20s and a low of 9 degrees. Not quite 1989 but darn close.

This is quickly becoming very concerning and a major disaster. I've never in my career seen models forecast this type of cold here, ever. I was too young to remember 1989 but this goes beyond 1989. This is more along the lines of 1899 or worse. I'm very concerned about the potential for a prolonged ...

I think the NAM will offer up a more realistic idea of what temperatures we may see. Arctic air is tricky and may be colder than models are advertising. Although I do find it strange that the GFS was so cold with "only" a 1047 mb high over the northern plains. Seems lightweight. We've push...

The Dallas AFD acknowledges the GFS regarding the biggest arctic outbreak since 1989. Good read. They're definitely not discounting the GFS completely. Waiting to see the Houston AFD. I see Houston has tanked our high for Sunday, too.

Man, if the GFS/CMC are correct, that would be a 1989 type freeze with a 1983 duration. The "best" of both worlds. That would spell disaster for Texas with crops and pipes. I'm still not ready to bite on such extreme solutions but man, this is incredible.

Well, if you want cold weather, the 12z GFS will make you smile. Wow. Has snapped back to a very cold run. Major winter storm on Saturday with highs in the 20s heading into Sunday.

00z Euro says no dice on the cold for the third run in a row. Sigh..

Latest GFS has teens for southeast Texas. I'm liking that! Soup making weather right there! Are you sure it's the GFS? I just looked at the 18z and the lowest I could find was 25 for Houston. I mean I did see 18 degrees for Huntsville and College Station on Sunday morning but I'm not convinced. Thi...

Battle of the ages setting up between the GFS/CMC vs the Euro. GFS/CMC say coats, jackets, layers, heaters, record cold Euro says una mas cerveza por favor while wearing shorts and a tank top. Euro has highs near 70 next weekend while the GFS and CMC are in the freezer at the same time with both mo...

CMC has a major ice storm for southeast Texas. You do realize that the CMC has us in the 20s for daytime highs on Friday, Saturday, Sunday and into Monday. That's never, ever happened before for that duration in our recorded history and no other model even comes close to that solution. The CMC is g...

I literally LOL'd. This wins the internet today. Thanks for the laugh.

Wow, the Euro just threw a wrench in everything. No arctic air at all through next Friday. 65 degrees for a high on Saturday. The 12z CMC has a high of 21 degrees at the same time. LOL

Looks like 12z GFS has now joined the CMC and Euro. No 1062 mega high. Cold here in Texas but nothing 'extreme' like the GFS and CMC showed yesterday.

Despite the stronger high on the 00z GFS, I was looking at a close up of the TMAX temps and yes, it'll be cold, but the bigger story for HOUSTON, not Texas, will be the long duration of high temps in the 40s it looks like with overnight lows down into the mid to upper 20s. I don't see anything remot...

I take that back. 00z GFS still has the 1062 high dropping into Montana at 224 hours and a 1058 high into CO and then 1048 into west Texas. Man, that's like ice age for Texas. It appears that the 00z GFS delays the high a bit as well. At 18z it had a 1057 high crossing into western ND around 6z on t...

Looks like the 00z CMC has joined the Euro camp and has done away with the mega, 1062 mb high for a more reasonable 1046 high. That's much more believable although the CMC is still showing highs near freezing by Feb 11th. Just have to watch and wait. The 00z GFS appears to be following close behind.
