Got about 2 inches in Bethel.  Looks like maybe an hour or so of more snow.  Those short term models were pretty much a failure for our area.  I really got sucked in thinking we would get more than a couple of inches...  Can't really compain as it is so rare to get snows more than 4 inches here, at least been fun to have so much to track so early in the season.

Didn't help the system was a fast mover either. At least we got a change over and had some snow fall from a storm that looked like it was going to be mainly rain 3 or 4 days ago. Probably another hour or 2 of light snow showers as it looks like the precip shield is really falling apart now. I expect most places will measure 2-3 inches when its all over.

 

From the looks of it, the Sunday storm isn't going to amount to much either, which isn't a bad thing given we were likely to see more rain than frozen from that anyways.
