MOUNTAINS...
.DISCUSSION...Isolated thunderstorms, mixed wet and dry, are
ongoing across Central Oregon and the Eastern Mountains this
afternoon. There is medium confidence (50%) in isolated nocturnal
activity tonight into Sunday morning over portions of Central
Oregon, the Eastern Mountains, and eastern parts of the Columbia
Basin. Sunday afternoon, scattered wet and isolated dry
thunderstorms are expected for the same region. Locally breezy
winds will also develop through the Cascade gaps each afternoon
and evening through early next week.
***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.
