New York City, Boston, Philadelphia, and other cities and towns across the northeast saw temperatures break 100 degrees on June 24 as a heat wave continues to impact the region throughout the last few days following the Summer Solstice.
New York’s John F. Kennedy Airport recorded that triple-digit temperature for the first time since 2013, Philadelphia, and Boston recorded the same shortly afterward. And 100-degree temperatures were even felt in Maine.
