I had to laugh at this in the main NOVA thread.  They are happy for the Euro as well but jaded from tonight’s runs.  

hahaha

A goose is going to fart midflight over Kansas later tonight and it will cause the gfs to show a radically different outcome in its next run.

I never pay real hard attention to the 18z and 6z model suites. They dont use fresh data. 0 and 12Z models use fresh data. 

They may use fresh data from weather stations and planes, and perhaps any special balloon’s launched. The 18z GFS seems to do better than 12z from what I’ve seen playing in WxChallenge.

I don’t like the NAM but it also is super early and it will change.  84 hours is max run time and snow/sleet is just getting .  48 hours is when I’ll start to worry. 

The NAM can often be the first to introduce mix lines where there were previously none. In this specific case it's probably over done. There's an unusual amount of wiggle room in the column but this far south there can never really be enough. However, the nam wreck the column because it drives an 850 low to nearly Pittsburgh lol. Mid levels are a warm air vacuum.

Can it break this way? Yes,  within the envelope imo. But the nam is a mesoscale model and the storm hasn't even organized yet. So the 84 hour panel is a complete digital evolution. NAM loves to go a little haywire beyond d2 in these situations. If the shortwave was over the MS river and getting organized, I'd be pretty concerned rn but we're not there yet and imho, it's pretty unlikely the NAM is "on to something" yet

Thanks for the insight Bob!  Let’s hope we all get another 0z Euro Run soon.
