GDD Probabilities

Posted: 20 Jun 2017 12:16 AM

The featured chart displays probabilities of reaching a given amount of growing degree days by a date shown on the y-axis after a planting date on the x-axis for Des Moines. The left hand plot presents the overall frequencies and the right hand plot shows the scenario based frequencies based on this year's data appended to by each previous year on record. The chart would indicate that we are in pretty good shape this year thanks to our reach stretch of very warm weather that helped to make up deficits incurred during May.

Voting:
Good = 6
Bad = 0
Abstain = 1
