KIMBALL, Neb. – In the wake of a departing weather front, air temperatures were slightly cooler across most of the region over the May 29-June 4 period. Clear skies, sunshine, and a lack of precipitation allowed many producers to catch up on spring fieldwork, and most were engaged in planting and summer-till.
Abundant May rains slowed fieldwork for much of the month, allowing weeds to put on a lot of growth. While water use in weedy fields was certainly elevated, those same weeds will decompose after tillage, returning nutrients to the soil.
The above-average spring rainfall and warming late-spring temperatures have also strongly boosted plant growth across pastures and rangelands. As June began cool season grasses were standing taller than has been the case for many a year, and biomass production well above average. Thus far in 2018, it’s been one of the all-time best grass production years in a couple of decades. Forbs and shrubs have done well this spring also, and many have been putting on a brilliant and colorful show just in time for Nebraska Wildflower Week, which ends on Sunday.
Cows and calves are, unsurprisingly, growing fat and sassy on plentiful spring grass.
With the abundant rains there has also been an uptick in insect populations, and across the southern Panhandle mosquito populations have been uncharacteristically and annoyingly large and bothersome.

U.S. Drought Monitor
High Plains: In south-central and southeastern Nebraska, recent triple-digit heat and dryness has been an issue, especially for pastures and alfalfa. Where 90-day SPIs were less than -1.5, moderate drought (D1) was introduced. This included a small area south of Omaha, which was linked to the D1 area in nearby Iowa. Moderate drought (D1) was also expanded across northern Fillmore and northwest Saline counties. Incidentally, Omaha matched or set four days of high temperature records during the long Memorial Day weekend (Friday through Monday). The highs ranged between 97 and 101 degrees.
Across northwest Kansas, widespread heavy rain (3 inches or greater, with some isolated CoCoRaHS totals of about 9 inches) warranted a one-category improvement in the depiction. Next week, once the rainwater has a chance to either percolate into the soil or run off into streams, additional alteration of the Kansas depiction may be needed.
Across the Dakotas, D0, D1, and D2 categorical areas were generally expanded in coverage, due mostly to recent precipitation deficits. There was one area of improvement (D0 was removed) in the Black Hills of South Dakota due to rainfall this past week.
West: Recent rain warranted a one-category improvement in drought conditions (D1 to D0) across northeast Montana, and the two areas of abnormal dryness in this region were consolidated into one. For now, despite recent heat and dryness, it was decided to hold off on introducing any D0 into extreme northwest Montana. Continuing snowmelt runoff and above average river and stream flows provide plenty of water in that area for irrigation.
In nearby Idaho, some areas are coming out of their worst flooding in years. Bonner County continues to experience flooding, and farmers in adjacent Boundary County will be struggling with crop loss from the saturated soils in that region.
In Colorado, some improvement in the drought depiction was made from approximately the Front Range just west of Denver eastward through Kit Carson and Cheyenne Counties near the Kansas border. Relatively small adjustments were made in New Mexico this week as well, especially in central and east-central portions of the state.
USDA Weekly Weather and Crop Reports
Colorado experienced mixed weather again last week with conditions deteriorating in drought-stricken areas and fieldwork delayed in others due to heavy rainfall.
Northeastern counties received good moisture early in the week, with tornadoes and isolated hail also reported. Fieldwork was delayed in areas where rain was heaviest. Reporters noted most crops were doing well. Warm weather and favorable soil moisture promoted emergence and growth of spring crops. Livestock and pasture were reportedly doing well.
East central counties received varying levels of precipitation, with southern areas receiving less. A reporter in Kiowa county noted winter wheat was beginning to show signs of stress from lack of moisture. They also noted some county producers were not planting corn or sorghum due to no moisture and extreme drought. Pasture conditions also deteriorated last week in this district.
Southwestern county reporters noted drought conditions did not improve last week, and a major fire was burning in La Plata county. Measurable precipitation was extremely limited last week.
In the San Luis Valley, a rain storm at week’s end brought beneficial moisture. Fall potato planting was virtually complete and emergence picked up.
Southeastern counties received minimal moisture last week. First cutting alfalfa was lighter than normal.
Statewide, winter wheat was just starting to turn color, with 53 percent of the crop rated good to excellent, compared with 48 percent good to excellent last year.
Stored feed supplies were rated 7 percent very short, 18 percent short, 74 percent adequate, and 1 percent surplus.
Sheep death loss was 47 percent average and 53 percent light. Cattle death loss was 75 percent average and 25 percent light.
No report available at press time.
Wyoming experienced above–normal temperatures for the week. Above-average temperatures were reported at 27 of the 34 reporting stations, with the high temperature of 90 degrees recorded at Kaycee and a low of 26 degrees at Yellowstone.
Above normal moisture was reported at 25 of the 34 reporting stations. Three stations tied for the low of reported precipitation, they were Jeffrey City, Big Piney, and Cheyenne at 0.15 inches. Newcastle reported the most moisture with 3.71 inches.
A reporter from North Central Wyoming noted that planting is finally done and crops are emerging and growing but some weevils have been noticed.
A reporter from Western Wyoming noted that they got some frost which has nipped the first crop of alfalfa.
A reporter from Southwestern Wyoming indicated a few small storms, but it has been mostly dry.
A reporter from South Central Wyoming indicated some moisture, but still scattered and spotty. They also indicated the irrigation water is holding up and the chances of a hay crop have improved. Another reporter from South Central Wyoming said parts of the county are extremely dry with low levels of water in the reservoirs. They also indicated ranchers have started to sell off cattle.
A reporter from Southeastern Wyoming they continued to get some rain, along with hail and tornadoes. They also indicated the wheat varies in quality but has improved with moisture.
Irrigation water supply across Wyoming was rated 1 percent poor, 8 percent fair, 86 percent good, and 5 percent excellent.
Stock water supplies across Wyoming were rated 2 percent very short, 8 percent short, 88 percent adequate, and 2 percent surplus.
