Ponds in Missouri were low and drying up further as drought conditions worsened across the state. Producers were hauling water to livestock. Brownfield Ag News (Jefferson City, Mo.), July 20, 2023

Intense drought conditions in Missouri were forcing cattle producers to sell more livestock than they normally would because pastures were drying up. Some were selling entire herds as the dry conditions meant that cattle needed their diets supplemented with hay and other grains earlier than normal. Some cattle producers never stopped feeding hay from the past winter. Flatland (Kansas City, Mo.), July 20, 2023

Grasshopper numbers were higher than usual this summer across much of Eastern Oregon. The grasshoppers reduced the yield from grass hay fields somewhat. They ate the grass as it grew, and stripped leaves from the alfalfa, leaving only stems. A rancher in the Keating Valley wore safety goggles while riding a four-wheeler to protect her eyes from the many grasshoppers. Capital Press (Salem, Ore.), July 21, 2023

Christmas tree seedlings were struggling and dying for lack of moisture. Newly planted seedlings on a tree farm in Linn County were dying. After the 2013 drought, a seasoned Christmas tree grower in Buchanan County learned to mulch and water each of his thousands of trees to help them withstand future droughts. Radio Iowa (Des Moines, Iowa), July 21, 2023

Below normal rainfall over much of Minnesota led the state Department of Natural Resources to place six watersheds in a Drought Watch Response Phase. The watersheds include the Mississippi Headwaters, Western Superior, Croix, Rainy River, Upper Mississippi-Black-Root and Upper Mississippi-Maquoketa-Plum. Four other watersheds--Des Moines River, Missouri-Little Sioux, Missouri-Big Sioux, Red River--remained in various drought response phases since the summer of 2022. Minnesota Department of Natural Resources (St. Paul, Minn.), June 15, 2023

The St. Croix Watershed entered the Drought Warning Response Phase, which requires public water suppliers in the watershed to implement conservation measures intended to reduce water consumption to 50% above January levels. The affected counties are Anoka, Washington, Isanti, Chisago, Pine, Kanabec, Mille Lacs, Carlton and Aitkin counties. KSTP-TV ABC 5 Minneapolis/St. Paul (Minn.), July 21, 2023

The Iowa DNR urged people to be careful at Lake Manawa in Council Bluffs due to the low water levels. The water was about 20 inches below the normal pool on account of drought. The low water made it challenging to unload and load boats. Oxbow lakes adjacent to the Missouri River were lower this summer due to drought conditions over the past few years, per the Iowa DNR.

Issued at 200 PM PDT Fri Jul 21 2023 000 WTPZ44 KNHC 212031 TCDEP4 Tropical Depression Four-E Discussion Number 3 NWS National Hurricane Center Miami FL EP042023 200 PM PDT Fri Jul 21 2023 Tropical Depression Four is currently struggling to produce deep convection within a highly sheared environment. Convection has waned since this morning, with cloud tops continuing to warm this afternoon. The low-level center has also become more exposed with remaining convection to the east of the center. Subjective and objective Dvorak satellite estimates from TAFB, SAB, and CIMMS ADT and AiDT range from 25 to 35 knots. Given the current structure, a blend of satellite estimates and recent visible satellite trends yields an initial intensity of 30 kt for this advisory. The depression continues to be in an environment of strong upper-level westerly wind shear. The system has crossed into cooler sea surface temperatures as well, with SSTs continuing to cool along the forecast track. Given these parameters it is likely the depression will gradually weaken, becoming a remnant low by tomorrow, and dissipating by 60 hours. The system is moving west-northwestward at 12 kt. A ridge centered over the southwestern United States should continue to steer the depression on this general heading and speed for the next 24 hours. Afterward, the shallow remnant low is expected to turn more westward in the low-level flow. The NHC track forecast lies near the previous forecast track.
