Heavy rainfall in Kansas helped the overall drought conditions in the High Plains Region, but not all states in the Region were as lucky. According to the U.S. Drought Monitor, the Region as a whole had all drought categories improve. The area of moderate drought (D1) or worse in the Region decreased 2% this week, to total 64.24%. This decrease in area mainly occurred in eastern Kansas, but Colorado and Wyoming had a decrease in D1 area as well. Although D1 slightly improved in Wyoming, severe drought (D2) expanded in the central portion of the state and extreme drought (D3) expanded in the southwest portion of the state. The same occurred in Colorado where D3 expanded along the eastern portion of the state and exceptional drought (D4) expanded in the southeast. However, monsoon moisture did help improve conditions in the northeast corner of Colorado, upgrading some of the area of D2 to D1. This moisture spilled over into the panhandle of Nebraska upgrading a small portion of D3. In South Dakota, drought conditions are returning in some areas where 30 day rain deficits total between 1.5-3inches. For this reason D1 was introduced in the southeast portion of the state along the Iowa border and D3 expanded in the southwest corner of the state. As mentioned before, Kansas had large amounts of rain this week with many areas totaling 4 inches or more. This rainfall caused a one category improvement in many areas of Kansas. This week the area of D1 decreased 13.27%, D2 decreased 11.25%, D3 decreased 5.37% and D4 decreased 2.42%. In the southeastern corner of Kansas abnormally dry (D0) conditions were removed along with a portion in the north central part of the state. In North Dakota, drought is still nonexistent, but D0 conditions continue to expand in the central portion of the state.
