Episode Narrative Post frontal showers developed in the wake of a cold front late in the afternoon across southern Pend Oreille County. A shallow layer of instability off the surface and ample low level moisture resulted in quick developing convective cells that produced heavy rainfall and pea sized hail.
Event Narrative Heavy rain fell at rate of approximately one and one quarter of an inch per hour resulted in fast flowing water down a sloped front yard of a residence. Loose soil was easily carried by the runoff, which created a flow of mud that covered the driveway of the residence. No damage was reported.
