Record Hot Streak Looks Safe for Another Year

The record number of consecutive days with 90 degree temperatures or greater, 22 set on July 30th-Aug 20th in 2007, looks to be safe for another year.  The high temperature Saturday at Standiford Field in Louisville was 86 degrees.  The table below tracks our streak of 20 days with highs greater than or equal to 90.

 The record longest streak stands at 22.  The table below gives the top 10 longest consecutive day streaks of greater than 90 degrees. 

Ranking Number of Days Date Streak Ended
1 22 8/20/2007
2 21 8/28/1936
  21 7/30/1901
  21 8/21/1900
5 20 8/5/2011
6 17 8/1/1999
  17 8/5/1940
  17 8/11/1896
9 16 7/29/2010
  16 8/11/1983
 

A few items of note with the dates above.  The streak that ended at 16 last year in late July was followed by 2 days in the upper 80s, then 15 more days at or above 90 (a streak tied for 11th).  Had those two days been a little warmer, that streak would have been 33 days!  A similar occurrence happened in 1983, when a 15-day string ended on 7/24 by 2 days of temperatures in the 80s, then followed by the 9th-ranked streak listed above.  Also, in 1901, another 15 day streak occurred before the tied for second streak of 21 days.  There were three days in between those two streaks!
