Cool temps, rain slow harvest; good for wheat and grass

Posted

KIMBALL – September transitioned to October in the midst of cooling temperatures and widespread light to moderate rain across much of the Tri-state region. While cloudy skies delivered rain across lower elevations, snow fell above the 6,000
foot level.

At Kimball the first frost arrived Tuesday morning as the mercury fell to 32 degrees.

The precipitation was timely for recently seeded winter wheat and for pasture and rangeland that was becoming a bit dry. In general, winter wheat germination had been good and some very nice stands are becoming established.

Cool season grasses and winter annuals perked up with the moisture as well. Although Kimball County and other parts of the Panhandle are behind for the year on precipitation totals, distribution and timing of rainfall has been quite beneficial in prolonging active and productive growth. Autumn grazing should be quite good this year, however, continued growth will also reduce soil moisture levels unless they are replaced by more precipitation.

Sugarbeet harvest was under way across much of the region last week, however, harvest was slowed by precipitation and wet fields.

Regional Forecast and Conditions

As of Tuesday morning (Oct. 3), the temperature at sunrise was 34 degrees under partly cloudy skies. There was a light frost. The day was expected to be sunny with a high near 60 degrees.

U.S. Drought Monitor

(Sept. 26) The High Plains: A stripe of heavy rain cut across the region from the central High Plains into the eastern Dakotas.

On Sept. 23-24, rainfall totals reached 4.04 inches in Huron, South Dakota, and 3.42 inches in North Platte, Nebraska. All dryness- and drought-affected areas within the region experiencing heavy rain saw improvement in the drought situation. This area of improvement included western and central Kansas; central Nebraska; and the eastern Dakotas.

There was some minor improvement noted in areas outside of the heavy rain band. Most of the region’s rangeland and pastures continued to improve.

Lingering effects from the Dakotas’ punishing summer drought left 57 percent of the rangeland and pastures rated very poor to poor on Sept. 24 in both states, according to the U.S. Department of Agriculture. In addition, South Dakota continued to lead the nation (among major production states) in very poor to poor ratings for sorghum (33 percent) and corn (27 percent).

National Summary: Relatively quiet weather prevailed for much of the drought-monitoring period.

Record-setting warmth accompanied the tranquil weather across the Midwest and Northeast. Very cool weather and locally significant precipitation affected the Northwest, including the Cascades and northern Rockies, boosting topsoil moisture and further aiding wildfire containment efforts.

Starting on Sept. 23, heavy rain erupted along an axis stretching from the southern High Plains into the upper Great Lakes region. The rain put a significant dent in rainfall deficits for areas still experiencing dryness or drought.

U.S. Conditions and Weather Report

(Oct. 3)  Dry weather dominated the East and Far West. The early- to mid-week period featured record-setting warmth across the Midwest and Northeast, while cool weather covered the West. Later, warmth began to return to the Far West, while seasonably cooler air overspread the eastern half of the U.S. Weekly temperatures averaged at least 10 degrees above normal in several locations from the lower Great Lakes region into New England, but ranged from 5 to 10 degrees below normal across the Intermountain West.

For several days, an axis of heavy rain stretched from southern sections of the Rockies and Plains into the upper Midwest. Weekly rainfall topped 2 inches in several areas, while lingering rain in the south-central U.S. boosted totals to 4 to 8 inches or more—sparking local flooding—in parts of Texas.

Elsewhere, light showers were mostly limited to the Pacific Northwest, Intermountain West, and Northeast. A few heavier showers dotted Florida. East of a line from northeastern Texas to Lower Michigan, however, warm, dry weather promoted summer crop maturation but reduced soil moisture for the germination and establishment of recently planted or soon-to-be planted winter grains and cover crops.

Under warm, humid, showery conditions, hurricane recovery efforts continued in Puerto Rico and the U.S. Virgin Islands, following Irma on Sept. 6 and Maria on Sept. 20. Maria’s direct strike on Puerto Rico as a Category 4 storm—the strongest hurricane to hit the island since 1928—left residents without electricity and other necessities, such as fresh food and running water.

Wyoming

Wyoming experienced cooler than normal temperatures for the week.  Thirty-three of the 34 reporting stations reported below average temperatures for the week with the high temperature of 77 degrees recorded at Old Fort Laramie and Sheridan, and a low of 21 degrees at
Big Piney.

Above normal moisture was reported at 20 of the reporting stations.  Lake Yellowstone reported the least moisture at 0.10 inches, with Afton reporting the most moisture with 1.43 inches.

A reporter from North Central Wyoming indicated that the rain has slowed harvest for beans, alfalfa seed, and sugarbeets.  Another reporter from North Central Wyoming reported that they got nice rains over the past week which made it a little wet for fall plowing.  They also indicated that corn silage harvest is complete and the livestock look good.

A reporter from Southwestern Wyoming reported that they experienced small storms during the week and have had cool temperatures with lots of mud.

A reporter from South Central Wyoming noted that most ranchers have indicated that they have moved livestock back to fall pastures which is early for several.  Another reporter from South Central Wyoming stated that it has been wetter than normal with cooler temperatures.

A reporter from Southeastern Wyoming reported warm weather for most of the week with only one day of moisture.  They also reported that crop progress and harvest are progressing on schedule.  Another reporter from Southeastern Wyoming indicated that they have been getting steady rains which may have caused some to replant their wheat.

Stock water supplies across Wyoming were rated 12 percent very short, 17 percent short, 65 percent adequate, and 6 percent surplus.
