.DISCUSSION...Fire weather conditions improve with moisture
advection moving into the area over the next few days. Showers
develop Tuesday across the mountain regions but only expecting
local wetting rains in the region. Min RH`s will be in the 20 and
30 percent range with good to excellent overnight recoveries.
***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 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. ***
