.DISCUSSION...

...Wetting rain and snow occurred this past Thursday...
...A period of drying is expected through Saturday...

Warm temperatures along with sunny skies and gusty west winds
continue to prevail this afternoon. Winds diminish some tonight
but remain gusty to about 20 mph. Minimum RH values will improve
tonight compared to what it is now. Overnight lows in the mid to
upper 30s will also reset fire potential overnight. Saturday looks
relatively warm again, but with lighter winds. RH values tomorrow
will bottom out between 29 to 40% in the area of the fire.

Otherwise, the clock has been reset on fine dead fuels due to
widespread wetting this past Thursday. This moisture recovery is
expected to be temporary with wind and low humidity resulting in
good drying conditions through Saturday. As such, expect upward
trend with respect to fire danger as fuels dry going into the
weekend.

Moisture returns late Sunday into Monday as a strong storm
system crosses the region.
