.DISCUSSION...
Dry weather conditions are expected through the early afternoon
before some late day showers and storms will likely pop up around
the area. Most of this activity should avoid the site but some
rain is definitely possible between 2-6 PM. Winds will also be
gusty for another day, which is likely to lead to excellent
dispersion indices above 70-80 which can result in uncontrollable
fire behavior. Winds will decrease for tomorrow, allowing
dispersions to fall back into the good range and conditions will
be mostly dry again tomorrow at least through the early afternoon
hours.
