The end result of these weather systems was above-normal precipitation for the week across much of the West, including the Pacific Northwest, California, Nevada, and the central to northern Rocky Mountains across eastern portions of the northern and central Plains, the southern Great Lakes, and western and southern portions of the Northeast and a band of precipitation from southeast Kansas to eastern Kentucky. The October 24th pressure was 942.5 mb, which is a record low pressure for the Pacific Northwest. According to the National Weather Service Weather Prediction Center, as the third low pressure system approached the Pacific Northwest coast, it set a pressure record, testifying to the strength of the system. Fed by an atmospheric river of Pacific moisture, its surface low and front left heavy precipitation across California with widespread rain and some high elevation snow from California and the Pacific Northwest to the Great Basin. The third system slammed into the West Coast near the end of the week.
Its surface low weakened as it crossed the Rockies, but it was re-energized over the Plains and generated precipitation across the central Plains, Great Lakes, and Northeast. The second brought precipitation to northern California and the Pacific Northwest. The first system early in the week spread precipitation across Wyoming to the Upper Mississippi Valley, then left scattered showers over the Northeast before moving off into the Atlantic.
