Rain fell in many parts of the country, with the greatest concentration of showers arcing across the Plains from the Southwest into the Southeast. However, significant rain bypassed the south-central U.S., where mostly dry weather was accompanied by late-week heat.
In fact, weekly temperatures averaged as much as 5°F above normal in many locations from the Pacific Coast to the Plains, except in areas that were cooled by clouds and showers associated with the monsoon circulation.
Meanwhile, cool air settled across the Midwest and Northeast—eventually reaching most areas from the Mississippi Valley eastward. Autumn-like conditions cloaked New England, where weekly temperatures averaged at least 5°F below normal. Another late-week development was the arrival of heavy rain across the northern Mid-Atlantic region, where totals of 2 to 6 inches were common.
Substantial showers also dotted the Southwest and neighboring areas, largely due to robust monsoon showers.
In contrast, little or no rain fell in the Pacific Coast States and across the nation’s northern tier as far east as the upper Great Lakes region. Parts of the Midwest were also bypassed by spotty showers, leaving some pesky dry pockets in the western Corn Belt.
Elsewhere, a few locations on the drought-stricken northern Plains benefited from widely scattered showers,
