In some years, however, rainfall in the summer months <br /> <br />is negligible and in other years it is several times the normal <br /> <br />amount. Two dry months in summer will likely result in dryland <br /> <br />crop failure, and one wet month in fall may prevent or seriously <br /> <br />delay crop harvest. <br /> <br />Temperature <br /> <br />Air temperatures in the basin may vary widely from day to <br />day; however, mean temperatures on a monthly basis vary only five <br /> <br />to ten degrees between widely separated areas. <br /> <br />During the period 1921 to 1965, the frost-free period <br /> <br />between the last spring and first fall temperature of 32 degrees <br /> <br />ranged from a low of about 130 days in the west to a high of about <br />170 days in the eastern part of the basin. <br /> <br />2-10 <br />
