EDIT: 12z Euro is out to 180 on Wunderground. You really can't get much different from the 12z GFS at 156+. It's more of a nasty looking phase type solution that brings colder air down but never really forms a storm as it shears out the SW system and leaves another cutoff behind. The result for here is rain. The long range euro is pretty blah as well.

I know what you are saying Doug, but I'm going after a bigger storm. You are talking about the N stream driving through bringing colder air, then the southern low kicks out and uses the air already here to produce wintry precip. That works for me. The 12z op GFS is indicating that the N system is going to dominate and keep the colder air locked up north. It's still pretty far out though. The problem with the more phased solution is if it happens, then the storm could track over us or west of us which isn't any good if you like winter, heh.

The Euro/UKMET has been kicking the GFS's butt again in the last 31 days as far as 500 MB in the medium range so I'm hoping for a good run, lol

Monkey see, Monkey do. The 18z GFS has come basically in line with the 12z Euro. The only problem is the trough remains positively tilted. Need the tilt to change or the trough to be farther SE in this type of setup.

Imagine if we have a winter like last season, it was cold yea and minus that one clobbering storm that dumped 23" that would have been one boring winter. That thing was our saving grace! All this talk is for when? Please dont say next saturday night and ice lol! Because thats when the xmas party is for our work and man its way up in clinton again this year which is almost 55 miles from our rental here.

Here is some food for thought this AM from SGF:

ANOTHER UPPER LEVEL TROUGH WILL ALSO SWEEP ACROSS THE NORTHERN U.S.

THIS WEEKEND SENDING A COLD FRONT TO THE SOUTHWEST. AT THIS TIME

HAVE GONE WITH ALL RAIN AS THE UPPER LEVEL LOW TO THE SOUTHWEST

SHOULD KEEP A WARM NOISE OVER MUCH OF THE AREA DURING THIS TIME.

WILL JUST HAVE TO SEE HOW DEEP AND HOW COLD THE AIRMASS WILL BE

DIRECTLY BEHIND THE COLD FRONT TO SEE IF ANY WINTRY PRECIPITATION

WILL BE POSSIBLE WITH THIS SYSTEM...SOMETHING GLOBAL MODELS ARE

NOT GOOD AT DEPICTING.

Next weekend it looks like.

12z GFS getting better.

Waiting on GGEM. Havent paid much attention to it much this year yet so dont know it's recent track history.

Probably not too good, at least the scores aren't. Euro is going to win again anyway.

Waiting on the 12z GFS Ensemble members, several older runs have been showing the 12z OP solution today.

yep GGEM is too far north for us. Curious to see what the Euro does, it starts in about 10 mins. As always, it's an on the edge thing here in the 4 state area. lol 12z GFS text output shows Joplin being 33 and rain during the heaviest.

This has to be one of the tougher forecasts in awhile for Plains NWS offices. At H+84, the NAM and ECMWF are almost polar opposites, with the GFS somewhere between (closer to the Euro, though). So by the weekend, it seems there would be three completely separate ideas:

1. All the energy ejects mid-week, so presumably no weekend storm. (NAM)

2. Some of the energy cuts off over the SW, then ejects toward the southern High Plains by the weekend, with a relatively cold storm. (GFS)

3. Some of the energy cuts off over the SW, then shears out to the NE, with a relatively warm and weak storm. (ECMWF)

It's possible there could still be some precipitation Fri/Sat with the NAM scenario, as there's a bit of energy over AZ/NM that's trying to separate from the main batch ejecting into the Midwest on Thursday. If there were, it would probably be something wintry, given the airmass invading the area late Thursday into Friday.
