.DISCUSSION...Fire weather concerns will remain elevated through
the week with continued hot and dry conditions. A slight shift in
the pattern Wednesday will bring increased chances (10-30%) of
isolated to scattered thunderstorms Wednesday afternoon to central
OR and the Eastern Mountains with unstable conditions elsewhere.
***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. ***
