We all know that it in the last two weeks, temperatures have warmed up considerably, but when we plot out the growing degree days (GDD), we can see how dramatic this warming trend has been (Figure 1). In Lafayette a couple of weeks ago, we had accumulated less than 100 GDD – now we’re closing in on 300. We’re still considerably later than last year, but tracking similarly to 2013, 2014 and 2015.
