INDIANAPOLIS – Most of Sunday will be dry throughout the day. Then Sunday evening into early Monday strong storms will be headed towards Indiana.

The rest of Sunday

Super warm days are ahead as we wrap up the summer season in Indiana. But just as quickly as we warm our air temperatures to the low 90s, a sharp drop in heat will follow. Storms late Sunday night.

Storms on the way late Sunday into early Monday

After a mostly dry weekend, showers and thunderstorms are on the way starting late Sunday night into early Monday morning. You may even wake up to some rumbles of thunder overnight Sunday. Some of these thunderstorms may even pose a severe threat, especially the closer you get to the Indiana-Illinois border. Strong wind and damaging hail, along with heavy downpours and excessive lightning are included in this storm threat.

Cooler air to finish out the week

Now here’s the fun part in the forecast! Right after this late summer warming takes place, a trough digs into the eastern part of the US, and will help cool our temperatures off significantly. We’ll pull in some cool air from the north, and drop those high temperatures back into the upper 70s by the end of this upcoming week.

Indianapolis 7-day forecast

September heat loves a comeback. We’ll warm up to temperatures in the low 90s to start the week, before a big dip in temperatures by the weekend.
