| Episode Narrative |
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. By this time, flooding was coming to an end on the Palouse River in the Palouse. Flood waters became an issue back on March 26th as the first in the series of wet storm systems moved through the area. 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. The extended stretch of wet weather was compounded by low to mid elevation snow melt that aided in the rises on the Palouse River. |
