March was cool and wet

Posted: 01 Apr 2019 05:34 AM

The featured chart displays the combination of growing degree day departures along with precipitation departures for March expressed in terms of standard deviation (sigma) for Iowa statewide averaged data. This year was on the cool and wet side of average, but nothing too extreme for either metric. Since the growing degree days are always zero or small positive number in March, the lower bound for a departure is tight. On the other hand, the upper bound is large and you may recall the epic warmth of 2012 which noticeably sticks out on this plot.

Good = 9
Bad = 1
