.DISCUSSION...
Limited to no fire weather concerns expected for rest of the weekend and
into much of next week. Cooler temperatures combined with a surge of
monsoonal moisture will lead to daily precipitation chances and fairly
high afternoon minimum humidity values. Wetting rains are expected most
days. Winds will be quite elevated mid-week, but the atmosphere remains
unfavorable for fire weather concerns.
