This past week some areas in the High Plains Region received some much needed rain improving conditions. Other areas in the Region were not so fortunate and had conditions worsen. According to the U.S. Drought Monitor, areas in Kansas and extreme southeast Nebraska saw rain totals of 4 inches or more. These rains helped improve the drought conditions in those areas by one full category. In areas of southwestern Wyoming, western North Dakota, and western South Dakota drought conditions continued to worsen. Overall, 88.07% of the Region is experiencing moderate drought (D1) or worse. Due to the substantial rains, the area of exceptional drought (D4) in the Region now totals 14.97%, a 1.23% improvement from last week. Wyoming saw an increase in area of about 13.5% in extreme drought (D3) or worse. In North Dakota conditions continue to worsen. Much of the state in now in an abnormally dry (D0) condition or worse and expansion of D1 is taking place in the southwestern portion of the state.
