High Temperatures
On August 20 in <NA> the average high temperature is 79.6 °F (26.5 °C). The lowest recored high temperature was 71.6 °F (22.0 °C) in 1997 and the highest recored high temperature was 95.0 °F (35.0 °C) in 1983. The high temperature is usually* between 75.4 °F (24.1 °C) and 83.9 °F (28.8 °C). About a quarter of the time, the high temperature is less than 75.4 °F (24.1 °C), and another quarter of the time, the high temperature is greater than and 83.9 °F (28.8 °C). About 95% of the time, the high temperature has been between 67.3 °F (19.6 °C) and 91.9 °F (33.3 °C).
