The Housing Market on the Decline?

This article stated that according to the National Association of Realtors, the US housing market showed signs of cooling as sales of existing homes eased last month. This goes on to say that in the coming months, we should see the supply and demand even out. However, I wonder how long this will hold true. In Cedar City, the demand for buying housed decreases in the winter because of the cold weather and the snow, rather than the perfect weather of summer. It says that the rates are seasonally adjusted, and that would be great if the housing boom leveled out a little for those looking for buying homes, but it seems somewhat likely that the boom could hit once again next spring.
