.DISCUSSION...Dry and unstable conditions will continue across the
mountains through Thursday with high pressure overhead. Onshore flow
looks to bring better RH recoveries Friday and into the early next
week. Over the weekend, monsoonal moisture may move into the region
to boost the chances for isolated thunderstorms, especially near the
Cascades, but confidence in the specific timing and coverage remains
low.
Forecast for 20 foot wind speed (valleys and ridge tops) are 10
minute averages reflecting RAWS winds.
