.DISCUSSION...The region will remain with elevated fire weather
through the period as there is some breezy with areas of low
relative humidity. This pattern will persist through mid-week
before giving way to an upper level trough that will bring
breezier conditions as well as the potential for mid level
moisture and instability across the region.
***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. ***
