Low pressure in the Central Plains will push a warm front up over Indiana late this afternoon and tonight. Weak upper level weather disturbances emerging from the low to the west will make it rain at times throughout the weekend. Here’s the computer-modeled radar from one particular computer model from Friday evening through the final cold front arriving Sunday night.
Severe thunderstorms are also a threat tonight.

It appears the rain may let up for several hours Saturday afternoon after the initial wave. There is a chance of showers and storms again Saturday night. Again: storms Saturday could be severe, especially south and west of Indy.
