High Temperatures
On May 1 in <NA> the average high temperature is 59.7 °F (15.4 °C). The lowest recored high temperature was 45.0 °F (7.2 °C) in 1978 and the highest recored high temperature was 86.0 °F (30.0 °C) in 1992. The high temperature is usually* between 53.8 °F (12.1 °C) and 65.7 °F (18.7 °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 65.7 °F (18.7 °C). About 95% of the time, the high temperature has been between 42.4 °F (5.8 °C) and 77.1 °F (25.0 °C).
Low Temperatures
On May 1 in <NA> the average low temperature is 47.5 °F (8.6 °C). The lowest recored low temperature was 37.9 °F (3.3 °C) in 1994 and the lowest recored low temperature was 68.0 °F (20.0 °C) in 2001. The low temperature is usually* between 43.4 °F (6.4 °C) and 51.5 °F (10.8 °C). About a quarter of the time, the low temperature is less than 43.4 °F (6.4 °C), and another quarter of the time, the low temperature is greater than and 51.5 °F (10.8 °C). About 95% of the time, the low temperature has been between 35.8 °F (2.1 °C) and 59.1 °F (15.1 °C).
Frost
On May 1 in <NA> expect the temperatures to drop below freezing for a risk of frost about 0.5% of the time.
