.DISCUSSION...Diurnally breezy winds through the Cascade gaps
today. A shift to a convective pattern will likely (70 percent
confidence) provide daily showers and thunderstorms for the
mountains through early next week. A low (5-20 percent) chance of
showers and thunderstorms over the Washington Cascades and
portions of the Blue Mountains today will be followed by
expanding chances (10-30 percent) of showers and thunderstorms
across all of the Cascades and Blue Mountains by Thursday/Friday.
***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
at the same time as max mixing height. ***
