.DISCUSSION...Winds will increase across the area tomorrow as a
surface cold front approaches the PacNW. Breezy west to northwest
winds will continue through the weekend behind the front passage.
Isolated thunderstorms will develop across southern half of
Oregon into the weekend, but chances are very low (10% or less)
across southern zones. Afternoon RHs will be low, with a few
critically low areas in the Basin, central OR, and the eastern
mountains. Overnight recoveries will be mostly moderate to good.
***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.
