Are we on the verge of a Snowy Owl irruption?

It looks like Snowy Owls are on the move this winter. With the widespread adoption of eBird, we now have an easy way to keep track of this phenomenon in a way that was previously difficult to impossible. Below I have posted the maps of the range and locations of sightings in both 2010 and 2011 over the months of Oct-Dec. It definitely looks like a better year than last. Will we see some Snowy Owls showing up over the next couple of weeks during CBC season? What do you think?

I am a young ornithologist originally from PA but now living in central New York. I am pursuing a master's degree at Penn State University studying grassland birds and their relationships with different agricultural practices. When I am not working feverishly on my thesis, I enjoy adding new birds to my county, state and life lists, digiscoping and getting outdoors. I am active in the Pennsylvania birding community as chairman of the bird records committee, as well as a reviewer for sightings submitted to eBird. Some topics that really interest me are migration, bird distributions and vagrancy. Contact me if you have any questions about birds and birding in PA.
