.DISCUSSION...A weather system continues to slowly push to our
east as light rain (20-50%) and isolated thunderstorm (15-25%)
chances extend across the John-Day Basin, Blue Mountains, and
Wallowa/Union Counties this evening. Another weak system is
expected Friday afternoon, bringing a return to light rain
(15-25%) and isolated thunderstorm (10-20%) chances to the John-
Day Basin and Wallowa County. Dry and warm conditions return over
the weekend.
***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 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.
