.DISCUSSION...
No red flag warnings are anticipated for this forecast/model
cycle. The areas south and west of of White swan/Harrah/Toppenish
could see meteorological red flag conditions briefly late this
afternoon into early evening that could last as little as an hour
in any locations along the fire zone 694/691 interface. For
Monday relative humidity will continue to be very dry to critical
across the OR/WA691 zones to the Wallowas and Grand Ronde valley
eastern OR700 and the John Day basin, but lacking winds. The
reverse is true over central Oregon and and northern central
Oregon where breezy conditions meets a little more moisture to
prevent red flag.
***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. ***
