.DISCUSSION...
An upper level system spinning off the Washington coast will
continue to promote occasional lowland rain showers and mountain
snow showers over the next few days. Gusty winds This Afternoon will
weaken This Evening. Due to extensive clouds and the nearby
system, temperatures will trend slightly below normal through the
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. ***
