Nationwide
Heavy precipitation fell across the Rocky Mountains of Montana, Wyoming and Colorado, as well as a large part of the South and southern Midwest. This brought widespread improvements to much of the South and Midwest, with scattered or widespread improvements in the Great Plains and Midwest.

Heavy precipitation falling over the Southeast brought improvements from central Alabama into the southern Appalachian Mountains, as well as the area surrounding the convergence of the Ohio, Mississippi, and Tennessee rivers. A small area of the Mid-Atlantic region missed out on much of the precipitation, leading to minor degradations. Very dry weather for the past few months increased fire danger in parts of the Florida Peninsula, and short-term moderate drought and abnormal dryness expanded in coverage.
Texas saw isolated degradations in the panhandle and south–where record-breaking temperatures converged with the lack of precipitation. The High Plains were a mixture of light to moderate precipitation, which greatly influenced where improvements or degradations were made.
Kansas, Colorado and Wyoming saw improvements where measurable precipitation fell. Degradations occurred in western Kansas and eastern Wyoming, where trace amounts of precipitation fell. Montana saw heavy precipitation, which improved conditions across much of the state. Isolated storms in western Oregon and Washington brought widespread improvements in Oregon, which continued into southwestern Washington. Central Washington, meanwhile, missed out on the precipitation and saw further expansion of abnormal dryness.
The West
Temperatures across the northern and Pacific coast of the West saw temperatures of 2-6 degrees above normal. Areas in northern California, northwest Oregon, south and central Washington and northeastern Montana experienced temperatures 6-8 degrees above normal.

Little to no measurable precipitation fell over much of the West, except for Montana, where 1-3 inches of precipitation fell. Conditions improved through most of central and western Montana, with slivers of improvement in the parts where the short-term dryness from the weeks past has shown improvement. Some isolated areas in western and southern Montana saw degradations.
Oregon saw widespread improvements in part due to the isolated precipitation and improved streamflow and soil moisture. These conditions were also seen in southern Washington, where improvements were made. Central Washington, however, missed out on any meaningful precipitation and saw temperatures of 4-8 degrees above normal, leading to abnormal dryness (D0) expansion.
The High Plains
The High Plains was a mixed bag of light to moderate precipitation, as well as improvements and degradations.

Wyoming and Colorado saw improvements and degradations closely aligning with moderate and light precipitation areas, respectively. Northern and central Wyoming saw improvements, which were a continuation of improvements made in Montana and South Dakota.
However, degradations occurred in areas that received trace amounts of precipitation along the eastern and southeastern parts of these states into northern Colorado. Northeastern Colorado also saw a slight introduction of abnormally dry (D0) conditions as overflow from adjoining areas of western Nebraska, where precipitation was low. Slight improvements occurred in the south and northeast areas of Kansas that received precipitation.
Elsewhere, conditions in central and western Kansas continued to degrade as streamflows, soil moisture, and groundwater continued to deteriorate. Southeast Nebraska saw slight improvements from continuous moisture over the past few weeks.
The South
The South saw a mixture of improvements in the north and degradation in the western and southern parts of the region.

Western Texas, central Arkansas and northern Mississippi saw trace amounts of precipitation, while central and eastern Texas, Louisiana, and central and southern Mississippi saw between 2-5 inches of precipitation. Precipitation helped alleviate conditions in northern, western and southern Oklahoma. Following the precipitation, further improvements occurred across northern Arkansas and western and eastern Tennessee.
The Texas panhandle and southern parts of Texas saw expansion of existing abnormal dryness—and a small sliver of moderate drought (D1) in far south Texas—with a lack of measurable precipitation and above-normal temperatures. — UNL Drought Monitor
