INDIANAPOLIS, Ind. --Good Sunday evening! A Flash Flood Watch remains in effect until 8 p.m. Tuesday for the southern half of Indiana, including Indianapolis. Periods of heavy rainfall will occur through the beginning of the week, leading to a flash flood threat.

DMA Flash Flood Watch Warning

Tonight, look for scattered light rain with more heavy rainfall moving in from the southwest toward  Monday morning. In fact, you may want to leave a bit earlier than usual for work as models show some of the heaviest coming in during rush hour. The heavy rainfall is forecast in association with an upper-air disturbance coupled with a stalled front across the area. Patchy dense fog is also forecast. Expect lows in the upper 60s.

A warm front will lift north across the region Monday night into Tuesday before a cold front swings through late Tuesday. These fronts, along with plenty of moisture and several upper-air disturbances, will once again lead to a heavy rainfall threat on Tuesday. Highs on Tuesday will reach the upper 70s.
