Abstract
Harrisburg (Saline County) has a temperate continental climate, dominated by maritime tropical air from the Gulf of Mexico from about March through November. Gulf air generally supports relative humidities of about 60% during the day and 85% at night. During these months, there are occasional, brief interruptions of drier, cooler air from the Pacific Ocean, but typically only last for a few days. From November through March, the Harrisburg area is dominated by Pacific Ocean air. Three or four times each winter, cold, dry air from the Canadian Arctic breaks south, bringing temperatures into the teens and even units. Average annual precipitation is about 45 inches, the highest for the state. The highest temperature on record is 113°F recorded on 13 July 1936, whereas the lowest is -23°F on 2 February 1951.
