Indiana Climate and Weather Report

The big story this week was the much-needed rain throughout most of Indiana that fell on Monday (August 19th). Since August 15th, this brought up to 5” of precipitation throughout west-central, southwest, and northwest Indiana (Figure 1). This was 2”-4” above normal for the past 2 weeks (Figure 2)! However, as we transition into September and hope temperatures stay warm to accelerate plant growth and catch up from a late-planting spring, climate outlooks are predicting higher probabilities for below-normal temperatures. Precipitation amounts are predicted to be neither above- or below normal for the first week of September, but should shift to higher probabilities of above-normal precipitation by the second week. Abnormally dry conditions continue throughout the state, but have not intensified. Where there was less rain earlier this week, relative soil moisture within the 10-40 cm depth remains below normal (Figure 3).
