251 PM PDT Wed May 14 2025
.DISCUSSION...Breezy to windy westerly winds are anticipated
through the Cascade gaps and across portions of the Columbia
Plateau this evening and again Thursday. A weak weather system
will push onshore late Thursday with low chances of wetting rain
for the mountains. Looking ahead, a more robust low-pressure
system is forecast this weekend with area-wide precipitation
likely. Widespread breezy to windy westerly winds are forecast
late Saturday 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.
