The Plains: Another mostly dry week over most of the plains states. Areas of Kansas, extreme southeast Nebraska, and portions of Oklahoma did record precipitation amounts that approached 4 inches in places. In these areas, full categorical improvements were shown specifically in northeast and south central Kansas, southeast Nebraska and central Oklahoma. In North Dakota, dry conditions led to the expansion of D0 conditions in the western half of the state and D2 expanded in the southwest. In the northeast portion of North Dakota, D1 also expanded. In South Dakota, D3 expanded in the western portion of the state while D1 expanded in the north central. More water restrictions were going to take effect in Sioux Falls as the flow on the Big Sioux River was below 50 cfs. In portions of southeast Oklahoma, D4 was expanded to include more of the area that has been missing out on the recent rains. Even with rains in portions of Texas, the consensus was that the impacted grazing lands are not showing much change, so no improvements were made. Degradation was shown in west Texas into New Mexico where a new area of D4 was introduced. Conditions also intensified and expanded in south Texas where another new area of D4 was introduced and all drought intensity levels pushed farther to the north. Some improvements were shown to D0 and D1 levels in central and eastern Texas as the area was refined to account for the most recent precipitation in the area.
The West: The active rainfall pattern continued over portions of Arizona, western New Mexico and southern Nevada. Many locations recorded well over 2 inches of rain during the last week and some even over 3 inches. With the recent round of precipitation and a wet pattern for most of the month, categorical improvements were made over central Arizona, western New Mexico and southern Nevada. In southern Arizona, the D3 was completely eliminated. In Colorado, the dry conditions and impacts in the northeast part of the state allowed for the expansion of D4 out of Nebraska, and D3 expanded across much of southeast Wyoming and into Colorado. In southeast Colorado, D4 expanded where conditions continue to worsen. Some improvements were made in central and southwest Colorado where D3 was improved to D2, based upon recent rains.
In Wyoming, the last several months have continued to be dry and many of the indicators were worsening as well. For southwest Wyoming, D2/D3 was expanded to the east and north while D0 was introduced in the far northwest part of the state. Nevada had D3 conditions expand into more of the Great Basin and D2 expanded to the north to include portions of southern Oregon.
