Temperatures soared well past 90 most everywhere while dewpoints climbed well into the 70s. At the Dutchess County airport near Poughkeepsie, the temperature crested at 99 degrees both days. On July 5, the dewpoint reached 79 to produce a heat index of 119 degrees! The heat index peaked around 110 degrees on July 6.
