High Temperatures
On April 20 in <NA> the average high temperature is 59.6 °F (15.4 °C). The lowest recored high temperature was 42.1 °F (5.6 °C) in 1991 and the highest recored high temperature was 82.0 °F (27.8 °C) in 1985. The high temperature is usually* between 51.9 °F (11.0 °C) and 67.4 °F (19.7 °C). About a quarter of the time, the high temperature is less than 51.9 °F (11.0 °C), and another quarter of the time, the high temperature is greater than and 67.4 °F (19.7 °C). About 95% of the time, the high temperature has been between 37.1 °F (2.8 °C) and 82.2 °F (27.9 °C).

The lowest recored low temperature was 37.0 °F (2.8 °C) in 1983 and the lowest recored low temperature was 68.0 °F (20.0 °C) in 1985. The low temperature is usually* between 41.1 °F (5.0 °C) and 51.5 °F (10.9 °C). About a quarter of the time, the low temperature is less than 41.1 °F (5.0 °C), and another quarter of the time, the low temperature is greater than and 51.5 °F (10.9 °C). About 95% of the time, the low temperature has been between 31.1 °F (-0.5 °C) and 61.5 °F (16.4 °C).
Frost
On April 20 in <NA> expect the temperatures to drop below freezing for a risk of frost about 3.2% of the time.
