Wider weather episode

A stagnant long wave pattern featuring a broad trough off the Pacific Northwest Coast and upper-level ridge over the central United States resulted in a parade of moist storm systems tracking through the Inland Northwest culminating on April 1st. An extended period of wet weather and low to mid elevation snowmelt through the final week of March resulted in high water levels on rivers and lakes in the Coeur d'Alene, St. Joe and Palouse River Basins. Daily rainfall accumulations ranged between a quarter to just over a half an inch for the week leading up to April 1st aside from March 28th. This concluded record setting precipitation totals for the month of March.
