.DISCUSSION...
Dry weather is expected through the weekend into next week,
though there is a low (<20 percent) chance of showers and
thunderstorms this afternoon in eastern Oregon. Temperatures are
expected to be much above normal with diurnal breezes each day.
***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.
