An intense Bermuda high became established over the mid Atlantic region during the Independence Day weekend. This high pumped heat along with very high humidity across western Massachusetts, especially on July 5 and 6. Temperatures soared to 90 or higher most everywhere while dewpoints climbed well into the 70s. At the Albany International airport, the temperature peaked at 94 on July 5 and 95 on July 6. However after combining humidity values, the heat index reached as high as 105 on both days. High temperatures were similar in the Berkshires.
