The high levels of humidity aid in the heavy, drenching downpours Thursday afternoon. Rain fall rates of .50" in 15 minutes were common late day. The eastbound storms moved rather quickly, departing for the many evening commuters.
Some storm reports include,
1.28" of rain fell in Rushville (Rush County) in 30 minutes
1.13" of rain fell in Straughn (Henry County) in 45 minutes.
1.08" of rain fell in Greenwood (Johnson County) in 60 minutes.
The stalled pattern is shaking free now that Hermine has dissipated and quieter times have return in the tropics. West to east bound weather systems are more freely moving across the nation now and a approaching cold front will bring more rain chance s to end the week.
Scattered showers and t-storms will persist through midnight especially over the central and south-central sections of Indiana Thursday night. The rain will eventually ease during the overnight hours. The cold front will slowly sag into the state Friday morning providing another round of showers and t-storms. Aided by a surface low and some upper-level air support, a few stronger storms are possible Friday afternoon and evening. The Storm Prediction Center has a portion of Indiana assessed for a 'marginal risk' of severe storms Friday. We will monitor timing and potential impacts of area Friday night football games.
