High Temperatures
On May 18 in <NA> the average high temperature is 67.6 °F (19.8 °C). The lowest recored high temperature was 46.4 °F (8.0 °C) in 2002 and the highest recored high temperature was 90.0 °F (32.2 °C) in 1996. The high temperature is usually* between 59.5 °F (15.3 °C) and 75.8 °F (24.4 °C). About a quarter of the time, the high temperature is less than 59.5 °F (15.3 °C), and another quarter of the time, the high temperature is greater than and 75.8 °F (24.4 °C). About 95% of the time, the high temperature has been between 43.9 °F (6.6 °C) and 91.4 °F (33.0 °C).
