Warmer, drier conditions expected next week

KIMBALL – Cool temperatures and rain were once again the weather story across the Panhandle of Nebraska and much of the tri-state region last week.
A slow moving weather front began to pass through the region last Thursday (May 25) bringing cooler air temperatures, breeziness, and widespread thundershowers. A friday thunderstorm delivered just over an inch of rain south of I-80 in Kimball County, while north of I-80 the total was considerably less. This storm also delivered a good deal of pea-to marble-sized hail.
As the weather front slowly moved out over the long weekend air temperatures remained slightly cooler than average and there was a good deal of breeziness.
Near Kimball winter wheat is well along in heading and will be flowering soon. Producers are generally behind in planting summer crops due to wet fields, and these same conditions have slowed tillage and spraying operations. Aerial applicators have been busy however.
Pastures and rangeland continue to develop nicely if slightly behind average due to cooler air temperatures. Cool season grasses are well into rapid growth and producing abundant biomass. Western wallflower and evening primrose are flowering, and larkspur is beginning to flower.

U.S. Drought Monitor

(May 23) The High Plains: A stripe of heavy precipitation from the central Rockies into the upper Midwest erased pockets of abnormal dryness (D0) in Nebraska and reduced coverage of dryness and moderate drought (D0 and D1) in Colorado.
Rain also trimmed D0 coverage in the eastern Dakotas. However, precipitation mostly bypassed the remainder of the Dakotas, leading to further expansion of D0. In addition a new area of moderate drought (D1) was introduced in the vicinity of the Missouri River.
On May 21, South Dakota led the entire northern U.S. in topsoil moisture rated very short to short (29 percent), as well as rangeland and pastures rated very poor to poor (19 percent), according to the U.S. Department of
National Summary: Soaking precipitation occurred from central portions of the Rockies and Plains into the upper Midwest, mainly from May 16-18, and in parts of the Southeast starting on May 20. Drought-affected areas of the Southeast, including portions of Alabama and Georgia, experienced substantial relief, with rain still falling when the drought-monitoring period ended on May 23.
Farther west, late-season snow (locally 1 to 3 feet) blanketed the northern and central Rockies, while streaks of heavy rain largely arrested drought development in the south-central U.S. Areas that remained stubbornly dry included parts of the north-central U.S. and Florida’s peninsula, although significant rainfall developed in the latter region after the monitoring period ended on May 23.
