.DISCUSSION...
Dry weather through early Friday will give way to increasing rain
chances later Friday (30-50 percent) mainly in western portions
of the area and then 30 to 60 percent everywhere on Saturday and
40 to 70 percent everywhere on Sunday. Winds will also increase
later Friday trough Sunday as a front moves across the region,
especially through the Cascade gaps and Columbia Basin. Breezy to
locally windy conditions are expected in these locations. With
the increase in moisture, MIN RH values will generally be above 40
percent in most areas.
***Winds are 20 foot 10 minute averages***
***CWR-chance of wetting rain 0.10 or greater***
***Ventilation Index is derived from the
transport wind multiplied by the mixing
height in 100`s of feet. Index categories
are a generalized indicator and users are
encourage to develop criteria that are
suitable and representative of dispersion
conditions in their local area of interest.***
Note: Max transport winds may not occur
at the same time as max mixing height.
