As we close the doors on May for the year, one of the biggest stories throughout the month was the precipitation. The entire state was above normal. Northwestern Indiana was 3.41” above normal and southeastern Indiana was 0.18” above normal for the month (Figure 1). Temperatures were near normal in the northern and above normal in the central and southern tiers of the state. Some stations in Central Indiana recorded rainfall on 24 out of 31 days.

The good news is that many areas saw dry conditions set in the last week of May and beginning of June and helped alleviate some of the saturated soils. This actually provided a very limited window of opportunity for the agriculture industry. Unfortunately, the weather looks to turn off wet again with 1 to 4 inches of rainfall projected through June 10th. The wet pattern looks to continue through the first three weeks of June with higher confidence in below normal temperatures and above normal precipitation (Figure 2 & 3).
