It's too bad that bulls-eye can't extend eastward into eastern Iowa.  3" would still be good, though.

Not very good dendrites here for accumulation. Maybe an inch thus far but going to be hard pressed to get 3" out of this unless something changes. The warning I believe is mainly for areas just to my NW and N. Still time, but not looking like warning material here.

The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

12z GFS/GFSv16/GDPS.... yes, we're into nowcast range, but after days of tracking it's nice to know each model's final prediction.

I think every model has 2.5-3.5" for Cedar Rapids.

Was interesting to watch the meteorologists struggle with what to make of those 18Z runs. I noticed the 0Z runs backed off though so it was a hard forecast 

Oh definitely was. But when in doubt know banding will always money wrench the forecast. This wasn't a typical storm but the low track with the available moisture I had a feeling that someone was going to get plastered. I honestly didn't think it was going to be us but I'll take it. This storm is actually pushing us to our all time snowiest winter. There is one on the 28th to watch too.

Someone in Jim Flowers' Facebook comments, who lives in Moorhead, IA (north of Omaha) is reporting 9".  Wow!  Gotta love the big, surprise over-performers.

The HRRR had another solid 12z run for my area (3+"), but it has been dwindling since then.  It has us down to only 2" now.
