WARM WITH A MIX OF SUN AND CLOUDS….

We’re experiencing another warm day today with a mix of sun
and clouds. Not really much weather to talk about today.

Once again today there has been little wind to speak of. The
average speed since 7 A.M. is only around 4 mph. We even had
a period this morning where winds were calm! The peak gust so
far is only 14 mph!!

Visibility hasn’t been great today, generally hanging out
between 35-40 miles due to haziness.

The high so far today is 79F, which is 8 degrees above the
normal high of 71F. The low since midnight is 55F, which is
2 degrees above the daily normal low of 53F.
