If you've seen a similar decline in previous years related to the arrival of warm weather, that may be it. Where I sit the weather the last couple of weeks has been much warmer than the same period the last couple of years. 2008 and 2009 both saw below normal temps for this time of year while 2010 has been well above normal.
