.DISCUSSION...Relative humidities in Kittitas are expected to
reach as low 15% with winds of 20-25 mph and gusts to 30 mph while

thunderstorms moving into the region.
***Thunderstorms imply strong gusty winds ***
***Winds are 20 foot 10 minute averages ***
***CWR: Chance of wetting rain 0.10 or greater ***
***Ventilation Index is derived from transport wind
multiplied by the mixing height in 100`s of ft.
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.
Categories: low (< 200), moderate (200-500),
high (500-700), and very high (> 700).
-Note: Max transport winds may not occur
