INDIANAPOLIS — It will be a hot September day for most areas, with temperatures climbing into the upper 80s to near 90 degrees. Areas that get a storm or too, will be a bit cooler.
A ridge in the upper levels will continue to build in the Great Lakes on Wednesday. This will allow temperatures to warm quickly. Afternoon highs will climb into the upper 80s and low 90s.
The first 90 degree day could be recorded in Indianapolis today or tomorrow. Typically, Indianapolis records two 90 plus degree days during September. The most ever recorded was in 1983 with 9 days of 90 degrees or warmer.
Cooler air is building in out west. Expect these temperatures swings this month.
