While dry conditions prevailed throughout much of the Southeast, Southwest, and northern Intermountain West, widespread precipitation covered much of the rest of the country last week.
According to today's Drought Monitor report of the U.S. Department of Agriculture (USDA), a strong low pressure system resulted in plentiful precipitation (0.5 to 3 inches, liquid equivalent) from the central Rockies east to the northern and central Great Plains during the week ending Oct. 19.
More than a foot of snow blanketed parts of Montana, Wyoming, and western South Dakota.
In addition, along a trailing cold front, heavy to excessive rainfall (1 to 3 inches, locally more) occurred across eastern Oklahoma and central to eastern Texas.
As this front progressed eastward, scattered thunderstorms with locally more than one inch of rainfall swept across the Ohio and Tennessee Valleys.
Much of New York and northern New England received 1 to 2.5 inches of rainfall Oct. 16.
Meanwhile, only light weekly precipitation amounts (generally less than 1 inch, liquid equivalent) were observed along the Cascades, coastal ranges of the Pacific Northwest, and northern Sierra Nevada Mountains.
