As we learned in our least forecast, Yakima(see comments) is on the dry side of the Cascades. Will the forecast stay on the dry side?
At 753PM, PT Yakima was reporting a temperature of 66 degrees with clear skies and a light west wind. There was some light rain on the Puget Sound, but the west, downsloping wind dried out Yakima quite nicely.
A sharp upper level trough is developing over the eastern Pacific, with the base well south of where is seasonably normal. An area of low pressure will develop over northern California and begin to work to the northeast. This will circumvent the Cascades and bring some rain to the Yakima Valley for Monday after a fairly pleasant Sunday.
