Highs on Saturday will be around 75 in Indianapolis, under mostly sunny skies.

There could be some storms in northern parts of Indiana, along the warm front, on Saturday, but bigger storm chances will arrive on Sunday.

The National Weather Service's Storm Prediction Center has placed all of southern Indiana, along and south of the Interstate 70 corridor, in a slight risk for severe weather on Sunday.

The storms will accompany a cold front that will push through the state, bringing cooler temperatures back into the region for the state of the work week.

The severe weather threat could shift before the storm system moves in.
