This is starting to look a lot like the Thanksgiving 2010 storm now... so train of rain and quicjk and sharp temperature drop and change over to all snow. And a week under a cold arctic dome with no snow pack lol...

REALLY lovely isn't it.... only thing it's doing is increasing the heat bill (and the gas prices, thanks OPEC)

Not just the High Plains either, some of the worst conditions I've seen here came as a result of 1-2" followed by sunny skies and high winds and zero visibility. This was just last winter, following the big 12/9 blizzard, and conditions were worse with the 1-2" of snow than with the nearly foot a few weeks earlier. It was unreal to be able to look up and see the sun, but not be able to see road signs within a few feet of my car. So even some lighter def band snows with this thing could carry significant impacts.

Yeah I have been in those conditions too. ND gets great ground blizzards with the flat plains and no trees/vegetation blocking anything. NWS lots of times in GFK issues blizzards outside of town with no warnings in town since buildings "block" the winds and keep ground blizzards from developing. I agree though, ground blizzards can get real bad sometimes.

Cheers to baroclinic_instability and the EURO. Both were ahead of the curve.

Ha thanks, but no need for congrats yet, a lot of little things to work out with details. GFS, unexpectedly, actually sped up the speed of this system. It has the surface low displaced farther E from the massive high over the Dakotas and a slightly weaker pressure gradient as a result. This will have big impacts on potential blizzard criteria. Also GFS places the heaviest snow corridor a tad bit more south. NAM also was a tad faster with the upper wave, so a trend may be developing there. Methinks somewhere in between as the wave may be faster, but strong cyclogenesis will result in a slightly slower surface low track.
