Ah...the last minute euro pull the rug thing. I guess that happens everywhere
I still have too much PTSD from 14 years living in the mid-Atlantic seeing snow storms disappear 4 hours before they're supposed to start.
Denver is your best bet to fly into, which is on the NE side of the city. That said you don't want to be on the NE side of the city for a snow storm chase, so take the drive over to Boulder.
