.DISCUSSION...
This evening, light and variable, terrain driven winds are
anticipated, with an increase in rain shower chances after sunset
and through the overnight along the Cascade caps and eastern
slopes. Winds increases through the Columbia gorge to breezy
conditions on Friday while becoming more windy Saturday and
Saturday night across a broader area of the Basin and central
Oregon. Precipitation chances increase through the weekend, with
minor snow accumulations (1 to 2 inches) across the higher
mountain reaches, however widespread wetting rains are not likely.
***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.
