.DISCUSSION...High pressure is building in across the area today
and this is expected to persistent through Saturday. This morning
easterly winds are fairly strong at the higher elevations above
the inversion, while the valleys are seeing light winds and patchy
fog. The site is likely above the inversion and may be seeing
some stronger east to northeast winds this morning. These winds
are expected to diminish this afternoon and will likely shift to
the north or northwest in the afternoon. Tonight these winds will
become easterly once again. Lighter winds are expected Saturday
and they may switch to the west in the afternoon. The mixing
height is expected to be lower on Saturday and the winds lighter.
Temperature and RH are expected to be similar both days. Sunday
