PLEASANTLY MILD TODAY WITH LIGHT WIND UNDER A MIX OF SUN AND CLOUDS…

What a spectacular day today! Temperatures reaching the low to mid
60s, with not much wind out there, it is making for a very pleasant
day to be outdoors. A mix of sun and mainly high level clouds just
adding to the beauty of the day.

As mentioned the wind has been on the light side since mid morning
after being a bit on the gusty side early this morning. The
average for the day thus far is around 11mph with a peak gust that
occurred in the wee hours of the morning of 27mph!

Visibility has been limited due to haziness in the air, holding
generally 40-45 miles today.

The high so far today is 62F, which is 18 degrees above the
normal maximum of 44F. The low since midnight is 40F, which
is 14 degrees above the normal minimum of 26F.
