.DISCUSSION...
Cool temperatures and unsettled conditions will continue through
the weekend with showers, and isolated thunderstorms, mainly over
the mountains. There could be some more widespread showers later
Sunday into Sunday night. Breezy winds will develop Monday. Drying
will follow Monday with a warming trend for much of the week. The
main fire weather concerns will be any lightning through the
weekend and any wind Monday, but overall fire weather conditions
remain low.
***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. ***
