Records are within reach today! The Indianapolis record high for September 2 is 100, from 1953. It could easily be tied. Humidity will be higher than on Thursday. Dew point temperatures Thursday never got past 65 in Indy, plus there was a pretty good breeze. Good thing: the temperature reached 99 degrees at 3:44pm EDT at the Indianapolis Airport Friday. That’s the hottest reading for September since September 6, 1954. The number of 90 degree days during 2011 going into Friday is now 39…the most for a year since 1988.
