.DISCUSSION...Main concerns over the next week will be hot and dry
conditions combined with gusty winds through the Kittitas Valley
and Columbia River Gorge. Weather models generally agree on a
pattern that supports high temperatures wavering around 100
degrees for the Columbia Basin Saturday onward, as well as gusts
up to 30 mph for the Cascade Gaps areas, at least through the
beginning of next week. Minimum RHs will generally be in the 20s
and teens across the lower elevations. Rain concerns look to be
limited until at least next weekend, should any occur.
***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.
