406 AM PDT Thu Sep 17 2026
.DISCUSSION...Will see some showers (50-70% chance) and isolated
thunderstorms develop (15-30% chance) across Central Oregon
through the Wallowas that include the Foothills of the Blues
through Friday. Not expecting abundant lightning with this system,
but could see wetting rains in local areas where the heaviest
precipitation occurs. Afterwards, drier air returns this weekend
with elevated fire weather conditions but not expecting any wind
concerns at the moment.
***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. ***
