U.S. Drought: Weekly Report for September 12, 2023
According to the September 12, 2023 U.S. Drought Monitor, moderate to exceptional drought covers 31.1% of the United States including Puerto Rico, an increase from last week’s 30.2%. The worst drought categories (extreme to exceptional drought) increased from 7.5% last week to 8.0%. The upper-level circulation over the contiguous U.S. during this U.S. Drought Monitor week (September 6–12) consisted of a subtropical ridge of high pressure across the southern states and Pacific weather systems moving in the jet stream flow across the northern states. Ridges dominated two areas—extending northward across the Rocky Mountains and across the East Coast. Upper-level troughs of low pressure that were associated with the Pacific weather systems favored two other areas—the Great Lakes to Ohio Valley and the eastern Pacific just off the West Coast. This atmospheric circulation pattern resulted in warmer-than-normal temperatures over the Southwest to southern Plains, northern Rockies, and Mid-Atlantic to Northeast. Cooler-than-normal temperatures dominated the week from the northern Plains to the Mid-Mississippi Valley and parts of the Great Basin to California. Cold fronts and surface low-pressure systems that were associated with the Pacific weather systems spread above-normal precipitation across parts of the Plains, Great Lakes, and Southeast to Northeast.
