Daily Degree Days

Posted: 22 Aug 2014 05:39 AM

The big story this summer is the lack of heat leading to a deficit in growing degree day accumulation. The featured chart displays the daily accumulation this year (dots) and the long term climatology (red line and filled segments). The brown extent represents the majority of the long term data range. You can see a number of days this year on the low end of the daily distribution and only a handful of dots above average since the start of July. Heat has arrived this week in Iowa, but next week looks to be back below average for this time of year.

Good = 19
Bad = 10
Abstain = 12
