.DISCUSSION...

Winds are expected to be light and variable through the overnight
with mostly clear skies. No precipitation is expected. Humidity
is expected to recover to near 90% tonight. Winds will turn to the
west by early Wednesday morning with a slight increase in speeds,
but gusts should remain below 8-10 mph. Some wind gusts up to 12
mph are possible late Wednesday morning into the afternoon as
winds turn to the east. RH looks to drop into the 30s for most of
Wednesday afternoon and then rebound into the 40s with increasing
moisture moving into the area as a storm system approaches. Clouds
should also increase by Wednesday morning and then decrease a bit
by the late morning.

Mostly cloudy skies are expected for Wednesday afternoon. Highs
will be in the low 50s. There is a low chance for precipitation
(~20%) on Wednesday afternoon, most likely in the form of a
rain/snow mix. The chance drops to near zero by Wednesday evening.
Note that the chance of wetting precipitation is at 10% or less.
No snow accumulation is expected. Smoke dispersal becomes marginal
for most of the day on Wednesday after being poor for Tuesday
night.
