.DISCUSSION...A weather system will bring breezy west to
northwest winds through the Cascade gaps and into the Columbia
Basin Friday; while localized overlap of wind/low RH criteria may
be met (50 percent confidence) in the Kittitas Valley Friday
afternoon, no widespread Red Flag conditions are anticipated. The
next chance of widespread precipitation and breezy winds will be
with a stronger weather system that is slated to arrive late
Saturday into Sunday.
***Winds are 20 foot 10 minute averages***
***CWR-chance of wetting rain 0.10 or greater***
***Ventilation Index is derived from the
transport wind multiplied by the mixing
height in 100`s of feet. Index 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.***
Note: Max transport winds may not occur
at the same time as max mixing height.
