The percent change in precipitation for both areas is dependent upon different emission scenarios; with higher emission levels in the future being conducive to greater extremes. Dramatic increases in average annual temperature are also expected, with average winter temperatures already having risen 7 °F in the past 30 years.
The Northern Plains' climate is semi-arid and is prone to drought, annually receiving between 16 and 32 inches (410 and 810 mm) of precipitation, and average annual snowfall ranging between 15 and 30 inches (380 and 760 mm), with the greatest snowfall amounts occurring in the Texas panhandle and areas near the border with New Mexico.
