PLENTY OF SUNSHINE FILTERED THROUGH HIGH THIN CIRRUS CLOUDS….

After a chilly weekend, today is proving to be a very pleasant
day with plenty of sunshine and only some decorative high
thin wispy clouds floating by. The temperature has responded
nicely as well with the mercury cruising into the low to mid
50s across the area.

To add to the comfort of the day, the wind has lessened since
early this morning with an average speed early this afternoon
only around 7-8mph.

Visibility however has been limited due to haziness, only
reaching 50 miles early this afternoon.

The high so far today is 52F, 14 degrees above the normal
maximum of 38F. The low since midnight is 28F, which is 7
degrees above the normal minimum of 21F.
