A severe thunderstorm watch was in place Monday evening for parts of central Indiana until 7 p.m. EDT, while a Flood Watch remained in effect until 2 a.m. EDT Tuesday for multiple counties across the region. Another line of storms could move through after 7 p.m. and before midnight, with the main threats south of I-70 including damaging wind and isolated tornadoes.
The weather threat matters because multiple inches of rain could fall south of I-70, adding to a night already marked by widespread showers and storms. Conditions are expected to stay unsettled into Tuesday, when highs are forecast in the low 60s and scattered showers are expected later Tuesday night.
Forecasts call for mostly cloudy skies in the early morning hours with lows near 60 degrees, followed by a few showers Wednesday morning before clouds decrease to partly cloudy skies. Wednesday’s high is expected to reach the mid-60s, and temperatures for the rest of the week into the start of the weekend should run below average in the 60s and upper 50s.
The tension in the forecast is not just that central Indiana is wet, but that the worst of the storm threat may arrive after the first round of watches and rain have already settled in. The pattern is expected to turn cooler after Wednesday morning’s rain chance, and dry conditions are expected to persist after that.
For people tracking Indianapolis weather, the answer today is straightforward: the immediate concern is severe weather and flooding tonight, and the broader shift is toward a cooler, drier stretch after midweek.
