About the Springfield, Missouri Climatology...
Springfield Missouri lies in a comparatively flat or very gently rolling tableland atop the crest of the Missouri Ozark Mountain plateau. The average elevation of the city is slightly over 1300 ft above sea level.
As a result of this advantageous location, the city and surrounding territory enjoy what is described as a plateau climate. The winter season in the Ozarks has temperatures considerably milder than in the upland, plain or prairie, and in the summer the ozarks are appreciably cooler.
The city of Springfield also occupies a unique location with regard to natural water drainage. The line separating two major watersheds crosses the north-central part of the city. Drainage north of this line flows north into the Gasconade and Missouri Rivers. To the south of the line, drainage is to the south into the White and Mississippi rivers.
The record temperature range is over 140 degrees with the lowest temperatures below -25 and the highest temperatures above 115 degrees. The growing season extends over a period of 199 days. Agriculture is greatly diversified, with practically every farm product of the temperate zone grown in this area. It is a noted livestock and poultry production and distribution center. The climate permits green pasturage all year long in varying quantity, resulting in ever increasing production for both meat and dairy products.
The air is remarkably free from industrial smoke, and because of the altitude, fog is fairly infrequent with only a few events of radiation or advection fog each year.
