To illustrate the snowmelt, here is the plot of snow water content at Stampede Pass at 4000 ft on the eastern side of the WA Cascades (normal snowpack is the light blue). We were near normal around April 1, but have lost about 20% since then.
During the next day, we are about to transition to a far cooler, wetter pattern as the ridge of high pressure weakens and moves westward. The upper flow pattern changes substantially. Here is the 500 hPa (18,000 ft) upper level map for 5 PM today (Wednesday). Big ridge centered over the Rockies, with a weak disturbance (trough) over Oregon--which has brought some thunderstorms to western Oregon and SW Washington.
The forecast total precipitation over the next two weeks by the GFS model is quite wet for the Northwest (see below), with some areas getting 4 inches or more. Temperatures will return to normal. I think folks are ready for some normal weather again.
