.DISCUSSION...Upper weather system and cold front passage will
bring light to moderate showers to the WA Cascades and northern
Blues. Breezy west to southwest winds will develop today, then
become light later this evening. Light winds with dry conditions
will return tomorrow through the early next week.
***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
at the same time as max mixing height. ***
