.DISCUSSION...
Unseasonably warm temperatures accompany dry and breezy to gusty north
to east winds early this week. Strongest winds gusting up to 25 mph are
expected overnight tonight through midday Monday. These drying northerly
winds and generally poor overnight humidity recovery in the Park Fire
vicinity will result in daytime humidities in the teens and elevated fire
weather conditions for much of the day on Monday. Lighter, but still breezy
winds and low humidity then expected to persist into Tuesday as well.
