Most verification scores are based on 500H and fronts, not waa, temps and snow maps. Everyone keeps saying the Euro has been rock steady. It has rock steadied a good 6-8" from me in less than 2 days.
Here is the Euro from less than 48 hours ago followed by the one today. These are 10-1 maps so the difference is even larger than shown here re Kuch. Now, no modeling has been been rock steady but the long range HRRR, when looking at 500H and fronts, is getting close to be just as valid at this point as a lower resolution global 24-36 hours before an event. Most professional forecasters do not use Global NWP's this close to an event. We do because we love the "game." You rarely see a short range AFD mentioning the Euro or GFS.
