High Temperatures
On October 21 in <NA> the average high temperature is 60.5 °F (15.8 °C). The lowest recored high temperature was 41.0 °F (5.0 °C) in 1987 and the highest recored high temperature was 80.1 °F (26.7 °C) in 1979. The high temperature is usually* between 53.8 °F (12.1 °C) and 67.1 °F (19.5 °C). About a quarter of the time, the high temperature is less than 53.8 °F (12.1 °C), and another quarter of the time, the high temperature is greater than and 67.1 °F (19.5 °C). About 95% of the time, the high temperature has been between 41.2 °F (5.1 °C) and 79.8 °F (26.6 °C).
Low Temperatures
On October 21 in <NA> the average low temperature is 47.6 °F (8.7 °C). The lowest recored low temperature was 34.0 °F (1.1 °C) in 1987 and the lowest recored low temperature was 70.0 °F (21.1 °C) in 1979. The low temperature is usually* between 42.5 °F (5.9 °C) and 52.6 °F (11.5 °C). About a quarter of the time, the low temperature is less than 42.5 °F (5.9 °C), and another quarter of the time, the low temperature is greater than and 52.6 °F (11.5 °C). About 95% of the time, the low temperature has been between 32.9 °F (0.5 °C) and 62.2 °F (16.8 °C).
Frost
On October 21 in <NA> expect the temperatures to drop below freezing for a risk of frost about 1.9% of the time.
