U.S. Weather/Crop Progress
U.S. Drought Monitor Weather Forecast: A strong upper-level low pressure system will move across the northern half of the CONUS during September 22-27 while high pressure generally dominates the southern half of the country. By the end of the period, the upper-level circulation pattern will consist of a ridge over the West and a trough over the East. This scenario will result in above-normal temperatures in the West and South with below-normal temperatures in the Northeast. Half an inch or more of precipitation, locally up to 2 inches, is forecast to fall from the Four Corners states to the northern Rockies and eastward to the central and northern Plains, as well as across parts of the Great Lakes, much of the Northeast, and over southern Florida. Half an inch or less is expected over Oregon, the Mid to Upper Mississippi Valley, the Tennessee Valley to Appalachian chain, and Mid-Atlantic Coast. Little to no precipitation is predicted for Washington, California, and Nevada in the West, across the southern Plains to Southeast, and over parts of the Midwest.
For September 28-October 5, the western ridge and eastern trough pattern is expected to persist. Odds favor warmer-than-normal temperatures across the West to Mississippi Valley and the Alaskan panhandle, with cooler-than-normal temperatures from the Northeast to southern Appalachians and over southwest Alaska. The circulation pattern will likely result in below-normal precipitation from the Pacific Northwest to Northeast, across the Great Plains to Mississippi Valley, and over the Ohio Valley as well as western Alaska. Odds favor above-normal precipitation over the coastal Southeast, the eastern half of Alaska, and a small area in the Four Corners states.
