Way up towards the North Western territories of Canada and slowing sliding down. Still showing at 162hrs

Well usually, but it can get extremely cold here without something extreme like 1060mb+. Just depends on the airmass you're working with really, but the stronger the higher is definitely a good thing. 1060 is quite impressive, especially being only 138hrs out.

I was just thinking to myself that Shreveport needs to get on board with the threat of wintry weather. The last several model runs have shown the Shreveport area to be in the middle of possible snow/ice/sleet/rain.

Nope, usually in hour increments, NAM first, then GFS, then Canadian, and of course they save the best for last (Euro) to keep us awake late nights. Each about 30mins to 1 hour apart.

Geez, don't be so modest

JB not long ago said he believes the core of the cold will be in the northern plains before things goes zonal which is kind of what the models have been hinting. I hope he is wrong. That's a lot of cold air damming and would be a waste if it never came down.
Update: the Canadian is showing the motherload of high's lol 1073 I think and brings it in the US at 1060+. I know the GGEM is cold biased but that's crazy.

Geez, don't be so modest. You've basically covered everything tonight. I don't see anything drastic on the GFS. Did catch a blip that the 500mb maps doesn't quite fit with the surface features. Which again shows we still hardly know the details and that the models don't have a handle of things well yet.

Those numbers are fun to look at. There certainly seems like there is going to be some mighty cold air. Like you were saying though, will it all come down? Who knows.

Euro sure is an eye opener! From the metroplex east, everything lines up perfectly for a snow event.
And like JB mentioned earlier another system not progged so well right now is on the horizon.

Was just coming to post. It looks pretty good for this next "event" if I'm not looking at it wrong. I'm drained, though. Hopefully tomorrow is a big day where we get some answers. I'll be looking forward to coming back home and catching up on everything.

Re: Texas Winter 2010-2011
Overall tonight's run were a plus in the snow department. Euro/Canadian/GFS (bit more towards the Arklatex though on the GFS) for winter precip here in NTX this weekend as the best dynamics move over head with the low through Texas. Lets see if the runs tomorrow can trend the same way.
