There were a LOT of showings in the fourth quarter of 2015 -- with 60% and 58% year-over-year increases in October and December.  But then January came, and along with January came lots of snow.  That seems to have been the main driver between the 41% decline in January showings as compared to a year ago. 

I suspect that as the snow continues to melt, and as some additional homes come on the market, that we will see a strong month of showings in February 2016.
