Growing Degree Day accumulation has been difficult this year thanks to the cool conditions that have persisted for most of the summer. The featured chart compares the summer to date accumulation since 1 May for this year, 2013, 2012 and 2009. This year has resembled 2009 quite closely and current deficits are below negative 200 units. There are warm temperatures in the current near term forecast, but it is starting to get late in the season as we are nearly to September 1 already!
