ALL TIMES ARE IN EASTERN STANDARD TIME

FIRST DAY OF JULY CONTINUES DRY STREAK ALONG
WITH INCREASED CLOUDS AND HUMIDITY

July kicked off today much the same way June went out with
dry conditions and above average warmth. The moderating
trend has continued since the weekend with yesterday’s maximum
of 87F being the warmest reading for the month of June. There
is a slight chance that today might make for the first 90F
degree day this year, however low clouds have been on the
increase by early this afternoon.

Check back tomorrow for preliminary monthly statistics as we
start to wrap up the month of June.
