.DISCUSSION...
Light winds, dry conditions, temperatures ~10 degrees above
normal, and valley inversions with poor mixing/ventilation continue
through Friday. Expect ridgetop gusts up to 45 mph today as a
weak system passes to the north. The next weather system arrives
Saturday, which will bring light rain (10-15% chance) along the OR
border, a cooling trend, and increased ridgetop winds.
Note: Thunderstorms imply gusty and erratic winds.
Note: Mixing Heights are in feet above ground level of the valley floors.
Note: Please see operating plan for detailed zone descriptions
