SUNSET:  1741E

MILD WEATHER CONTINUES WITH MAINLY CLOUDY SKIES….

Clouds have been the theme today with light winds this morning.
The temperature has been on the mild side as a warm air mass
has been advected up the eastern sea-board the past couple of
days.

As mentioned, the wind was light during the morning out of
a westerly direction. However the direction has since backed
to the south and is starting to increase as a rather potent
cold front approaches the region. Gusts are so far reaching
the low 20s mph, but are expected to continue to increase as
we get toward the evening hours with gusts perhaps pushing or
exceeding 50mph here on the summit!

Visibility has been declining as the day rolls on due to an
increase in haziness. We could see 50 miles early this morning,
but only to 35 miles by early this afternoon.

The high so far today, which occurred at midnight, is a balmy
62F, which is 21 degrees above the normal maximum of 41F. The
low since midnight is 48F, which is 24 degrees above the normal
minimum of 24F.
