Indiana to Remain Wet for a While
Published: Friday, June 19, 2026
Since last Friday (June 5), many parts of Indiana have seen a significant amount of rain. However, the spatial variability illustrates how there can never be enough ground observa-tions and measurements to tell the entire story.
In a 24-hour period over the weekend, an observer in Lafayette, Ind. recorded 3.58 inches and yet three miles to the northeast, other CoCoRaHS observers measured less than 2 inches. Less than 10 miles to the northwest, those CoCoRaHS observers measured less then 1.25 inches!
These differences play a huge role in knowing where there might be flooding, where drought may still be a problem, and where National Weather Service precipitation radar algorithms may need to be improved. If you're not already a volunteer CoCoRaHS observer, please consider signing up (https://cocorahs.org). With a manual 4-inch rain gauge, you can help provide data to the scien-tific knowledge of rainfall, rainfall impacts and infrastructure development for your area.
All the rain is due to both increasing temperatures (added energy and therefore rising air) and increasing moisture flowing northward from the Gulf. Now that the ground has become well saturated in most areas and vegetation is thriving, evapotranspiration has been add-ing even more humidity to the air. Say hello to hot and muggy conditions!
Dew point temperatures —the temperature the air would need to cool down to for the air to become saturated and condensation to occur—was around 70 degrees by the middle of this past week. Yikes! That makes nighttime air feel so damp and sticky.
Indiana will remain in this rainy pattern for at least another week, with the forecasted seven-day totals ranging from .5 inches (east-ern/southeastern Indiana) to almost 2 inches (northwestern Indiana). Beyond that, climate outlooks are slightly favoring cooler than normal temperatures with the possibility of above-normal precipitation. There is a slight risk for a heavy precipi-tation event sometime around June 18-20.
