Monday at a glance

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 upper 80s and low 90s, a sharp drop in heat will follow. Storms late Sunday night.

Cooler air to finish out the week

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 and beyond.

Indianapolis 7-day forecast

September heat loves a comeback. We’ll warm up to temperatures near 90 to start the week, before a big dip in temperatures right after. Highs in the upper 60s aren’t out of the question this week as well!
