By the time the month was over, there were several long standing temperature records broken at Little Rock (Pulaski County).

From June 30th to August 28th, there were 60 consecutive 90 degree days (a record). This surpassed a 57 day streak in 1980.

 

Consider This
As pointed out in a recent email from a retired National Weather Service employee, the consecutive 90 degree record would not be even considered this year if not for July 19, 1954. That day ended a string of 42 straight days of 90 degree temperatures at Little Rock (Pulaski County). On the 20th, a new string began and lasted 53 days. Overall, it could have been a 96 day run...which is well above the actual record.

 

The average summer temperature record of 85.4 ºF in 1954 was well under the 85.8 ºF reading established this year.

While hot daytime temperatures contributed to the latter record, nighttime readings really made this record possible. Readings at or above 70 degrees occurred on 77 straight mornings (June 8th to August 23rd), which is a first. It was close in 1938, with a 75 day string of 70 degree lows (July 1st through September 13th).

Nighttime readings were warm elsewhere as well. Seasonal lows were the second warmest ever at Pine Bluff (Jefferson County). At Harrison (Boone County), the average low was the warmest since 1980, and the second warmest on record. In August alone, lows were above 75 degrees on 9 mornings. This was the most in ten years.
