Indiana experienced a typical midsummer weather pattern during July, with warm temperatures, humid conditions, and scattered thunderstorms across the state. These conditions helped crops continue developing at a near-normal pace despite a cooler start to the growing season earlier in May.
By July 28, growing degree day accumulations varied across the state, ranging from about 1,440 units in northern Indiana to more than 2,080 units in southern regions. July's warmer conditions helped many areas catch up after slower crop growth earlier in the season. Most locations recorded between 75% and 125% of their normal heat accumulation levels, allowing crop development to remain largely on schedule.
One of the key weather features during July was the persistence of warm nighttime temperatures. While daytime temperatures were only slightly above average, overnight temperatures remained significantly higher than normal. Maximum temperatures generally stayed 1°F to 4°F above average, while minimum temperatures frequently ranged 4°F to 5°F above normal. These warmer nights played an important role in raising overall monthly temperatures and supporting crop growth.
Rainfall patterns, however, were much less consistent. Most of the precipitation came from scattered thunderstorms rather than widespread rainfall events. As a result, some locations received abundant moisture while others remained very dry.
From July 1 to July 28, rainfall totals ranged from less than one inch in parts of central Indiana to more than six inches in selected northern and southern areas. The differences were significant even between nearby regions. Central Indiana experienced rainfall deficits of 2 to 4 inches below normal, while some northern and southern locations recorded several inches above average precipitation.
The contrast in rainfall was clearly visible across the state. Plymouth in Marshall County received nearly 10 inches of rain during the period, while Monrovia in Morgan County recorded only about half an inch. Because rainfall was highly localized, dry conditions began to reappear in some regions.
According to the July 28 U.S. Drought Monitor, approximately 9% of Indiana was classified as abnormally dry. This marked a change from the end of June, when the state was free from any drought classifications.
Looking ahead, additional rainfall is expected through scattered thunderstorms. Forecasts indicate north-central Indiana could receive the highest rainfall totals, with localized amounts reaching up to 2.5 inches. Weather outlooks for early August also suggest above-normal temperatures and near- to above-normal precipitation. However, because summer storms remain scattered in nature, rainfall distribution is expected to continue varying greatly from one location to another across Indiana.
