April is indicative of vegetation rapidly greening up, accumulating growing degree-days, and those infamous April showers. After March’s memorable precipitation events that left most of the state 1”-2” above normal, perhaps a week or two without significant rainfall would be welcomed! Unfortunately, the 6-14-day outlooks are showing increased confidence that Indiana will experience above normal precipitation (Figure 1) with increased confidence of below normal temperatures (Figure 2) near the end of that period. The climate outlook for month of April is suggesting above normal temperatures so hopefully the end of the month will be warm and dry enough for productive planting. Growing degree-days have been slow to accumulate, but that is not necessarily unusual.
Figure 1. Probability of above or below normal precipitation amounts for April 8-12, 2019. Indiana is showing 40%-60% probability that precipitation will be above normal.
Figure 2. Probability of above or below normal temperature for April 10-16, 2019. Indiana is showing 33%-55% probability that temperatures will be below normal.
