.DISCUSSION...High pressure aloft will impact the PacNW through
next week, resulting in a drying and warming trend. Winds will
mostly be light and diurnally/terrain driven, though locally
breezy conditions will develop through the Cascade gaps Friday
and Monday afternoons.
***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. ***
