Intense low pressure across southwest Minnesota late afternoon will continue to pull slowly away overnight. Several bands of snowfall will continue to wrap back across the area into the evening hours, one a gradually dissipating band through the James Valley, with another intensifying band near I-29 and wrapping into adjacent areas of southwest Minnesota and northwest Iowa. Additional snow accumulations are expected mainly in the 1 to 3 inch range, bringing storm total snowfall to 12 to 16 inches in the mid James Valley and westward toward Chamberlain, tapering off to a broad 2 to 4 inch snow eastward into much of southwest Minnesota. While conditions will slowly begin to improve during the evening west of Interstate 29, conditions east of interstate 29 will continue to degrade into the evening hours.
Very strong north to northwest winds will also continue into the evening, which will continue to produce periods of blizzard conditions west of a Arlington to Yankton line into early evening, especially concurrent with heavier snowfall late this afternoon.
