.DISCUSSION...A trough of low pressure offshore will produce a
slight chance of showers or thunderstorms over the North Cascades
on Saturday. A trend toward much warmer and continued dry conditions
are expected early next week as an upper level ridge strengthens
over the region. Relative humidity values in the Cascades and
portions of the Olympics are expected to approach critical
thresholds toward the middle of next week with the potential for poor
overnight recoveries.
Forecast for 20 foot wind speed (valleys and ridge tops) are 10
minute averages reflecting RAWS winds.
