.DISCUSSION...
Over the next several days, weather conditions remain favorable
for minimal fire concerns. Monsoonal moisture, and some
precipitation chances through Saturday, will keep relative
humidity in the 20s to 30s, while winds remain mostly light
through the period. There is a lower probability (<30%) of
lighting that could start fires Friday, as wetting rain
possibilities are also quite small during the period.
