Flood Watch issued: “Rain Train” targeting central and southern Indiana | 13Weather Blog

INDIANAPOLIS — A Flood Watch has been issued for much of central and southern Indiana as the tracks of a “rain train” set up across the state. This persistent conveyor belt of steady — and at times heavy — rainfall will continue through Wednesday morning.

The Flood Watch spans from the I-70 corridor south to just north of the Ohio River. Within this zone, rainfall totals exceeding 1.5 inches are possible, which may lead to:

• Street flooding

• Rapid rises on creeks and streams

• Ponding of water on roadways

• Reduced visibility overnight

If you’re traveling overnight or early Wednesday, use extreme caution. Water-covered roads can be difficult to see in heavy rain and low light conditions. Remember: Turn around, don’t drown.

By later Wednesday into Wednesday night, some thunderstorms could re-emerge — especially across south-central Indiana. A few of those storms may become severe.

Primary threats if storms strengthen are:

Again, flooding remains the higher-end concern area-wide.

Forecast modeling suggests rain coverage will diminish Thursday afternoon. However:

Even as steadier rain ends, low clouds and damp conditions may hang on for part of the day.

Rain and thunderstorm coverage Friday drops to about 30–40%. With less widespread rain and entry into the “warm sector,” temperatures will soar into the mid-70s — a noticeable warmup.

Another round of potentially widespread rain and storms arrives Saturday along an approaching cool front. That front is expected to clear the state by Sunday morning.

The payoff?
☀️ Sunshine
🌤️ Pleasant temperatures
🌬️ Drier air

A beautiful finish to the weekend appears likely.

This is an evolving forecast with multiple rounds of rain and storm chances. Be sure to:

• Monitor rainfall totals in your area

• Never drive through flooded roadways

• Check for updated alerts before traveling
