During the 7-day period ending Tuesday morning, areas of heavy to excessive rainfall provided widespread drought relief across the central and southern Atlantic Coast States and from Texas northward into Montana and the Dakotas.
Please note the wet weather pattern continued through the week; any rain that fell after 12z Tuesday (8 a.m., EDT) will be incorporated into the following week’s drought assessment.
The overall trend toward improving conditions in the south contrasting with increasingly dry weather in the far north continued, though some northerly areas benefited from locally heavy rain.
In southern Kansas, another week with moderate to locally heavy showers (1 to 3 inches, as high as 3.72 inches in Longton, KS) led to widespread reductions of drought intensity and coverage.
Nevertheless, 6-month precipitation in the state’s lingering Extreme Drought (D3) was less than half of normal, while the Exceptional Drought (D4) in the state’s southwestern corner stood at less than one third of normal over the same time period.
Moderate to heavy rainfall (locally more than 3 inches) in northeastern Colorado likewise trimmed the coverage of Abnormal Dryness (D0).
In southeastern Nebraska, increasingly dry conditions over the past 90 days (40-60 percent of normal) led to a modest increase of Moderate Drought (D1) southwest of Lincoln.
Farther north, sharply wetter conditions between Bismarck, ND, and Aberdeen, SD, (6.17 inches in Java, SD) resulted in a considerable reduction of D0.
Beneficial rain (1 to 2 inches) was also reported in northeastern Montana, where D0 was reduced accordingly.
Meanwhile, D1 and D2 were increased somewhat in North Dakota from Bismarck to the Canadian border, where 60-day rainfall shortfalls (locally less than 30 percent of normal) have added to the region’s lingering long-term drought.
