.DISCUSSION...

Though relative humidity will fall below critical fire weather 
thresholds for the majority of the region for the foreseeable 
future, Friday marks a relative lull in winds. Gusts will top out 
at 25 mph for most locations with localized areas reaching 30 mph.
Another brief system rolls through Saturday though, prompting a 
sharp increase in gusts to 35-45 mph. Critical fire weather 
conditions will thus be widespread on Saturday before we fall back
into a marginal fire weather pattern next week.
