AUGUST DISSCUSION
The preliminary report for August shows that we had a cool August and very
dry conditions. An interesting note for the month is that we did not reach
90 degrees once. We started off cool and refreshing with highs struggling
to make into the 80s most day. However towards the end the month we had a return to warm
and humid weather, which balanced out the cooler temps to make the month only finish
about -0.8 degrees. August 2013 will go down in the history books to contain very beautiful
weather. We got 65% of possible sunshine, with an average high of 78.5. In New England,
weather doesn’t get any better. With all of the sun we obviously finished below average
for rain. However even though it was dry we are still running above normal for precip.
