KIMBALL – It was a week of dry and balmy mid-October weather across most of the tri-state region of southeast Wyoming, northeast Colorado, and the Nebraska Panhandle. Daytime conditions were for the most part sunny, warm, and calm, and producers took advantage of this to continue harvest activities.

In and around Kimball County sugarbeet harvest continued at a high pace and most producers were in the home stretch. Sugarbeet yields were reported to be quite good and with reasonably good sugar content. The warm weather was less than ideal for sugar production but quite good for harvesting. Some dryland corn was also being harvested, though that effort was just getting started. For the most part, forage harvest has been wrapped up with only bale collection and distribution remaining.

Well managed pastures and rangeland continued to hold up well. The late flush of green, photosynthesizing cool- and warm-season grasses also continues to hold up, largely due to a nice soaking on October 10-11. Winter annual grasses such as downy brome also remain lush and green and are providing good fenceline grazing in many locations.

As of Tuesday afternoon (October 24) the National Weather Service was predicting sharply cooler air temperatures and a significant chance of rain followed by snow beginning Thursday. Daytime highs were predicted to fall into the 30’s and 40’s with overnight lows dipping into the low teens and approaching single digits. The chance of precipitation is generally forecast as high, however, rain and snow quantity is expected to be fairly low. The seven-day forecast anticipates a warming trend beginning on Monday with daytime air temps rebounding into the 40’s.

Wyoming – A combination of warmer temperatures and minimal rainfall led to 6.8 days suitable for field work across Wyoming during the week. As the fall season advances, harvest progress was nearing completion for most crops throughout the State. Temperatures across the State were warmer than average, ranging from 6 to 15 degrees above average. Rainfall was minimal this week as the majority of areas received no measurable rainfall at all, while some received up to a half an inch.

According to the U.S. Drought Monitor, Wyoming was free from severe (D2) drought or worse, although 1 percent of Wyoming was categorized in a moderate drought (D1), and 4 percent of Wyoming was categorized as dry (D0). Drought-free conditions were at 95 percent.

Reports from Goshen County indicated some reporters had made a fourth cutting of alfalfa hay, while their corn harvest had started off slowly.

Lincoln County reporters noted the completion of their second cutting of alfalfa hay, while being close to completion on harvesting their small grain crops.

Reports from Platte County indicated strong pasture conditions, and producers had started harvesting sugarbeets and corn for grain. So far this year, the county has not had any frost under warmer than average conditions for this time of year.

Stock water supplies across Wyoming were rated 2 percent very short, 19 percent short, and 79 percent adequate, compared with 1 percent very short, 15 percent short, and 84 percent adequate last week. 

Colorado – Moisture Harvest advanced quickly last week due to nearly ideal conditions. The entire State remained dry last week and no measurable precipitation was received. According to the U.S. Drought Monitor published on October 19, drought conditions remained prevalent in western and southwestern counties and continued to spread last week. Over 19 percent of the State was experiencing abaveragely dry conditions, and 16 percent of the State was rated in moderate drought. Over four percent of the State was rated in severe drought, unchanged from last week. Temperatures were above average across the State last week, with eastern counties 6 degrees to over 9 degrees above average and some northern localities more than 12 degrees above average. Northeastern and east central county reports noted harvest of spring crops made good progress last week amid dry conditions. Livestock producers continued selling and shipping calves. In the San Luis Valley, alfalfa hay harvest was complete and many producers were finished with potato harvest by week’s end. Livestock remained in good condition and forage quality in pastures was reported as average for the time of year, but conditions remained dry. Hay supplies were notably shorter than average in the area.

Fourth cutting of alfalfa advanced last week with 79 percent harvested, ahead of the 5-year average of 73 percent.

Corn harvested for grain progressed well last week, with 45 percent of the acreage harvested, compared to the 5-year average of 47 percent.

USDA Weekly Weather Bulletin, October 24

Pervasive dryness favored autumn fieldwork, including summer crop harvesting and late-season winter wheat planting. By October 22, more than three-quarters (77 percent) of the intended U.S. winter wheat acreage had been sown. From the Pacific Coast to the Plains and upper Midwest, warmth accompanying the dry weather promoted emergence and establishment of recently planted wheat.

Weekly temperatures averaged at least 10 degrees above average across parts of the northern Plains and much of the West. Some of the warmest weather covered the northern Intermountain West, as well as northern sections of the Rockies and adjacent High Plains. In contrast, readings averaged 5 to 10 degrees below normal in parts of the middle and southern Atlantic States.

Meaningful precipitation was confined to the Pacific Northwest and an area stretching from the Great Lakes region into the Northeast. Widespread weekly totals exceeding 2 inches were confined to New England and neighboring areas, such as eastern New York.

USDM reports derive averages from only the most recent 30 year period. Temperature and precipitation predictions derive from National Weather Service (NWS) and National Oceanic and Atmospheric Administration (NOAA) forecasts.

Current drought status for the Nebraska Panhandle, Southwest Wyoming, and Northeast Colorado. Drought Categories: D0 – average dryness. D1 – moderate drought. D2 – severe drought. D3 – extreme drought. D4 – exceptional drought.

(October 17, 2023) A low-pressure system moved across the contiguous U.S., bringing heavy precipitation (greater than 2 inches) across much of the central Plains and Midwest this week. While in the southeast, upper-level energy moving across the Southeast brought rain over parts of Alabama, Georgia, South Carolina, and northern Florida, before moving into the southern Mid-Atlantic. The most widespread improvements were made to northern Nebraska, eastern South Dakota, southern Minnesota, southern Wisconsin, northern Indiana and southern Texas where more well above average precipitation was observed this past week. Dry conditions continued across much of the Southern region, with widespread degradations occurring across the Tennessee Valley, central Mississippi Valley and northern parts of the southern Plains. Following a wet September, minor improvements were warranted for parts of Washington.

High Plains: Heavy precipitation brought widespread improvements to the southeastern parts of the region, especially along the South Dakota and Nebraska border. Much of northern Nebraska received at least 2 inches of precipitation, with some areas reporting more than 7 inches this week. One-category improvements were made across northern Nebraska, while 2-category improvements were made where historic rainfall was reported. The heavy precipitation also improved dryness (D0) and moderate to severe drought (D1-D2) conditions in eastern South Dakota. A small area in southwest Nebraska, Chase County, was degraded to D1 due to acute dryness over the past two month. In Kansas, northern parts of the state received precipitation this past week but not enough to lead to large improvements. Precipitation did improve a small area of extreme drought (D3) in the central part of the state, in the counties of McPherson and Saline. Status quo was maintained across much of the state with some degradation occurring along the eastern part of the state based on SPI/SPEI and soil moisture data.

West: Precipitation fell across much of the West with heavy precipitation along the coast from Washington to northern California, where more than 1 inch of precipitation occurred this past week. Above-average precipitation led to improvements to severe drought (D2) in southwest Washington, along with dryness (D0) to extreme drought (D1-D3) improvements to western Oregon and D0 to moderate drought (D1) improvements in northern California. Beneficial precipitation led to improvements in moderate drought to extreme drought (D0-D3) in portions of northwest Montana. Status quo was maintained across the rest of the region this week.

Near-term forecast: Looking ahead through October 28, the NWS Climate Prediction Center (CPC) favors near to above-average precipitation throughout much of contiguous U.S., Alaska and Hawaii with below-average precipitation most likely across the East Coast and in parts of southeast Alaska and on the Big Island in Hawaii. Increased probabilities for above-average temperatures are forecast from the Plains to the East Coast, as well as much of Alaska and Hawaii, while below-average temperatures are likely across much of the West.

Terminology: EDDI – Evaporative Demand Drought Index. This is an experimental model for drought prediction, using nationwide data from 1980-present. SPI – Standardized Precipitation Index, correlating present month/year precipitation with 30-plus year historical data. SPEI – Standardized Precipitation Evapotranspiration Index. SWE – Snow Water Equivalent.
