Indianapolis, IN – An unsettled and stormy pattern is shaping up for central Indiana this week, with multiple chances for thunderstorms beginning Monday afternoon. Residents from Lafayette to Indianapolis and south to Bloomington should prepare for potentially disruptive weather that could bring heavy rain and lightning. The primary threat for today, Sunday, remains isolated showers and a few thunderstorms mainly south of the I-69 and I-70 corridors through the evening hours.
According to the National Weather Service in Indianapolis, the risk for thunderstorms continues and expands through the coming week. Monday will see a slight chance of showers and thunderstorms, primarily between 2 p.m. and 5 p.m., with a high near 85 degrees. While widespread severe weather is not anticipated, these storms could produce dangerous lightning and brief, heavy downpours that may lead to localized flooding in low-lying areas.
The wet pattern intensifies midweek. A greater chance for showers and thunderstorms arrives Tuesday night and becomes more widespread on Wednesday and Thursday, just in time for Juneteenth celebrations. The main hazards associated with these storm systems are heavy rainfall and potential for localized flooding, impacting counties across the region, including Marion, Hamilton, Johnson, and Hendricks. Drivers should use caution on area roadways, as sudden downpours can reduce visibility and create slick conditions.
Officials advise having multiple ways to receive weather updates throughout the week. While spotter activation is not expected through Tuesday, conditions may change. Be prepared to move outdoor activities indoors if thunder is heard. The threat of showers and storms currently extends through next Saturday.
