September Heat and Dry Weather

Wednesday marked the third consecutive day with an average temperature at the Indianapolis airport exceeding 80 degrees. The last time this occurred so late in the year was in September 1939.  Prior to 1939 this happened in 1936, 1931, 1927, 1897 and 1895.

The maximum temperature of 96 degrees on Tuesday was a record for the date and the latest 96-degree reading in the year since September 21, 2010. The minimum temperature of 74 degrees on Tuesday tied a record for the date and was the warmest minimum temperature for so late in the year since September 1939.  Wednesday's high temperature of 95 tied the old record set all the way back in 1897.  The high should normally be 80.

The dry weather that began in August continues in September at the airport. This is only the tenth time where no measurable rainfall occurred in the first eleven days of September since weather records began in 1871. The last time this occurred was in 2005. The record is 28 days set in 1963...the driest September on record. Measurable rainfall occurred after 7am EDT at the airport.  A few central Indiana areas received over an inch of rainfall today.  A significant break in the dry weather may not occur in all areas but temperatures will become noticeably cooler.

Below are pictures taken at the Indianapolis Weather Office on Tuesday when the temperature was 96 degrees.
