An experienced met who I trust, corresponded with me this evening via Facebook messaging and mentioned he believes that the arctic air may be too shallow to be adequately depicted on the models. He believes an ice storm situation may be shaping up for somewhere in the plains early next week.

I personally can see the fact that the models won't handle the arctic air, but I am not for sure precip chances are in our favor.

You know, I'm sort of tired of our region rarely being the bullseye of a storm. It's not that I'm wanting terrible weather conditions by any means, but I get tired of being on the outskirts of a system or in the questionable or on-the-line section of a forecast map.

But, I guess that's why the Ozarks is entertaining for forecasters — so many variables and factors that have to be considered every single time.

NAM did come in colder at 84, we get kind of a frontal thing happening over us again. There's multiple waves all over the Pacific and the models are having troubles picking up on the waves and what the waves will do.

Well in our case we better hope the Euro is correct because the GFS is crap. At least the Euro might offer up some type of overrunning scenario. The GGEM shows some signal for precip around day 5 but mostly for the OK and AR crew. It may be getting time to reload the cold and have a mild spell to end the month and then hopefully see some action in Feb. This NW flow pattern we're in certainly doesn't do much for us but you get the feeling we're in it for the remainder of the winter. It's even failed to produce an ice storm so far.

Yea man this has been a crappy winter. Oh well what can you do though really. Hopefully this lanina pattern goes bye bye for next year?

I've read that we may be going into a cycle of more Ninas (of varying intensity). Not to say there won't be any Ninos at all.

yeah, NW Flow rarely gives us anything good around here. We need those southwest storms. Just complete northern stream domination so far. I thought before winter started we may get lucky with storms digging down into Texas then ejecting NE through Arkansas and on NE from there but the storms so far this year really haven't wrapped up much at all. I guess the La Nina flow has been too progressive.

And you know historically LaNina's have had some good results in this area. I went back and looked at snowfall totals for Springfield during the Ninas from 1950-2000 and the avg was around 19". I came up with a total of 16 winters during that span and may have missed a couple but the sample size is adequate. The guys over at the SGF NWS will tell you that ENSO phase is not a big determining factor in the Ozark area WRT snowfall but it's hard to argue against that NW flow with Nina. I'm sure there are many other factors that come into play here but it sure appears we're in the middle of a stinker here this winter.

yeah it was probably a combination of the -AO/NAO blocking along with La Nina or something. The typical storm track during La Nina's usually gives us some of those storms that dig into Texas then eject NE which gives us snow. I thought we would have a decent winter because of that, but so far this year most storms haven't been able to really wrap up. It's been weak waves of storms ejecting out instead of one big storm. Also it seems that during times when we've had a chance for a big storm, the northern stream has crushed it.

I guess the JMA is going with the Euro as well?

Yeah I think it looks more like the Euro. Not a bad looking setup by day 6 on the JMA.

So i guess it can be allright but things have to be exactly right it sounds. We are just in this crappy flow pattern it seems. Hell we can still get a big snow in march but it just melts fast cause of the sun angle. The last 2 years i have seen my biggesr storms in late march. Last year a 6.5" one then when we lived in clinton that 8" one in march there. You just never know out here things change so rappidly on a dime. I do have to say i miss the big east coast snow storms. It kinda spoiled me ya know lol. These little 2-3" storms are nothing to me. Everyone in this town panicked last week from 3" i was like eh this is little stuff to me lol. Sux though cause they dont plow the back roads at all and ours is just a snow packed ice rink still

Chicago Wx posted this in a different thread about the Euro:

If we want to get technical, via the 12z Euro, it's probably a decent icing event for southern/southwest MO (including STL I'm assuming) with a good hit of snow farther north from KC to pretty much all of IA, SW WI, W IL...before it weakens a bit from 144 to 156/162 for the rest of IL/IN/WI/MI (i.e. lighter amounts), etc.
