The drought conditions in the High Plains Region continue to be very dynamic. This past week, monsoon moisture brought relief to dry southwestern portion of the Region. However, the lack of precipitation deteriorated conditions in the southeastern portion of the Region, which had an abundance of precipitation just a few months ago. According to the U.S. Drought Monitor, the area of moderate drought (D1) or worse ticked up 0.78%, to total 67.00% of the Region. This increase in D1 was in northeast Kansas and west-central South Dakota. Severe drought (D2) area also increased this week in the Region, to 48.02%. Monsoon rains dropped several inches in areas of Colorado this week, causing D1 to be upgraded in the north-central portion of the state, extreme drought (D3) to be upgraded in the northeast and south-central and exceptional drought to be trimmed back almost 1% in the southeast. This monsoon moisture also crossed into Nebraska upgrading some D3 on category in the southwest part of the state. In eastern Kansas and Nebraska, conditions have taken a turn the past few weeks. Earlier this year, this portion of the Region had well above normal precipitation totals, but with rains lacking the past 30-45 days, abnormally dry (D0) conditions are beginning to return. For example, in Lincoln, NE, precipitation in April and May was a combined 5.46 inches above normal. Meanwhile, in June and July (through 7/17), precipitation is 3.82 inches below normal. Conditions in Wyoming this week remained the same and again North Dakota remains drought free.

The map to the right shows precipitation departure from normal over the past 30 days.
