This Week's Drought Summary (9/27)

The combination of energetics from northern Mexico lifting toward the Southern Rockies/Great Plains and enhanced moisture from the remains of a tropical depression led to heavy precipitation events across the south-central U.S., particularly notable as a frontal zone stalled. Significant rain fell across much of the South, leading to much improved drought conditions in many areas. In fact, several regions across the U.S. received at least double (or more) of their typical precipitation for this time of the year over the past week, including the far Pacific Northwest, eastern Montana to northern Nebraska and Iowa and western Wisconsin, southwestern Arizona into northwestern New Mexico, and a large swath encompassing much of Texas northeastward to southern New Hampshire, part of which was from the remnants of Florence, now classified as the second wettest storm of the past half century to impact the U.S. Parts of the Southeast and most of the West were dry and drought conditions spread or worsened in several regions.
