.DISCUSSION...Seasonal temperatures and dry with diurnally breezy
winds through the Cascade gaps today. High confidence (70-95
percent) in a shift to a convective pattern Wednesday through the
weekend. A low (5-20 percent) chance of showers and thunderstorms
over the Washington Cascades and limited portions of the Blue
Mountains Wednesday will be followed by expanding chances (10-30
percent) of showers and thunderstorms across all of the Cascades
and Blue Mountains by Friday and Saturday.
***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. ***
