Wider weather episode

A wet spring season resulted in saturated soils across the Inland Northwest. Rivers, small streams, and creeks began to rise as temperatures warmed on May 13th and 14th as snowmelt infiltrated many watersheds across the Central Panhandle. Warm and dry weather transitioned to cooler but considerably wetter conditions over the weekend on May 15th into early the next week. An upper level low pumped a considerable amount of moisture into the region with an extended period of heavy rain falling Sunday into Monday. Forty-eight hour rainfall totals were up to between three-quarters and one inch for many locations across the Coeur d'Alene Area and the Central Panhandle Mountains.
